{"question": "Mechanism of action of Abatacept is ( REPAEAT)", "exp": "Abatacept is a soluble fusion protein that consists of the extracellular domain of human cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) linked to the modified Fc (hinge, CH2, and CH3 domains) poion of human immunoglobulin G1 (IgG1). Abatacept is produced by recombinant DNA technology in a mammalian cell expression system. The drug has activity as a selective costimulation modulator with inhibitory activity on T lymphocytes. It is used in the treatment of Rheumatoid ahritis. Ordinarily, full T cell activation requires 1) binding of the T cell receptor to the antigen-MHC complex on the antigen presenting cell (APC) and 2) a costimulatory signal provided by the binding of the T cell's CD28 protein to the B7 protein on the APC. Abatacept, which contains a high-affinity binding site for B7, works by binding to the B7 protein on APCs and preventing them from delivering the costimulatory signal to T cells, thus preventing the full activation of T cells. Abatacept is the basis for the second-generation belatacept currently being tested in clinical trials. In organ transplantation, it is intended to provide extended graft survival while limiting the toxicity generated by standard immune-suppressing regimens such as calcineurin inhibitors (eg, ciclosporin).

Mech of action:- This class of oral antidiabetic drugs are selective agonists for the nuclear peroxisome proliferator-activated receptor g (PPARg) which is expressed mainly in fat cells, but also in muscle and some other cells. It enhances the transcription of several insulin responsive genes. Glitazones tend to reverse insulin resistance by enhancing GLUT4 expression and translocation. Entry of glucose into muscle and fat is improved. Hepatic gluconeo- genesis is also suppressed. Activation of genes regulating fatty acid metabolism and lipogenesis in adipose tissue contributes to the insulin sensitizing action. Lipolysis and plasma fatty acid levels are reduced. Adipocyte turnover and differentiation is accelerated by glitazones. Thus, fatty tissue is a major site of their action. Improved glycaemic control results inlowering of circulating HbA1C and insulin levels in type 2 DM patients. Pioglitazone, in addition, lowers serum triglyceride level and raises HDL level without much change in LDL level, probably because it acts on PPARa as well to induce expression of reverse cholesterol transpoer and some apoproteins.

{"question": "Beta blocker used safely in hepatic disease is", "exp": "Ans) a (Esmolol) Ref: Gondmun & Gilman 11thedition KDT 6th ed p.139, Katzung edEsmolol has a half-life of about 8 minutes and it contains an ester linkage, and it is hydrolyzed rapidly by esterases in erythrocytes. The half-life of the carboxylic acid metabolite of esmolol is far longer and is about 4 hours which accumulates during prolonged infusion of esmolol which is excreted in the urine. Soit can be safely given in liver diseasesBisoprolol is well absorbed following oral administration with bioavailability of -90%. It is eliminated by renal excretion (50%) and liver metabolism to pharmacologically inactive metabolites (50%).CarvedilolCarvedilol is a third-generation b receptor antagonist that has a unique pharmacological profile. It blocks bl, b2, and al receptors similarly to labetalol, but also has antioxidant and antiproliferative effects. It has membrane-stabilizing activity but it lacks intrinsic sympathomimetic activity. Carvedilol produces vasodilation.It is thought that the additional properties (e.g., antioxidant and antiproliferative effects) contribute to the beneficial effects seen in treating congestive heart failure. Carvedilol does not increase b receptor density and is not associated with high levels of inverse agonist activity. Carvedilol is rapidly absorbed following oral administration, with peak plasma concentrations occurring in 1 to 2 hours. It is highly lipophilic and thus is extensively distributed into extravascular tissues. It is >95% protein bound and is extensively metabolized in the liver, predominantly by CYP2D6 and CYP2C9.

Life- long therapy is required, except in some cases of head injury or neurosurgery, where DI occurs transiently. The dose of desmopressin is individualized by measuring 24 hour urine volume. It can be used in transient DI and to differentiate neurogenic from nephrogenic DI--urine volume is reduced and its osmolarity increased if DI is due to deficiency of ADH, but not when it is due to unresponsiveness of kidney to ADH.

{"question": "The mechanism of action of local anesthetics is that they act on Na+ channels in their", "exp": "The mechanism of action of local anesthetic is by blockade of sodium channels in their activated state. Local anesthetic drugs interfere with excitation and conduction by action potentials in the nervous system and in the hea by blockade of the voltage-gated Na channel. Drug affinity varies with gating state of the channel. The drugs show low affinity at slow excitation rates, but high affinity when the channels are opened and inactivated during action potentials at high frequency, as they are during pain or during a cardiac arrhythmia. The drugs are thought to access their binding site in the inner pore by passage through the membrane and entry through the inner pore vestibule. There have been three major developments in the last decade that greatly increase our understanding of their mechanism of action. Firstly, amino acid residues critical to drug binding have been located by mutagenesis, and it is possible to develop a molecular model of the drug binding site. Secondly, a path for drug access directly from the outside has been characterized in the cardiac isoform of the channel. Thirdly, the hypothesis that high affinity binding stabilizes the fast inactivated conformation of the channel has been challenged. Rather, the drug may stabilize a slow inactivated state and immobilize the voltage sensor in domain III in its activated outward position. The combination of mutational study of the cloned Na channels and patch clamp offers the oppounity to understand the detailed molecular mechanism of drug action and to resolve drug structure-function.

{"question": "Drugs that are highly bound to albumin", "exp": "Plasma protein binding 1) Highly plasma protein bound drugs are largely restricted to the vascular compament because protein bound drug does not cross membranes,thus they tend to have smaller volumes of distribution. 2)High degree of protein binding generally makes the drug long acting, because bound fraction is not available for metabolism or excretion, unless it is actively extracted by liver or by kidney tubules. 3) One drug can bind to many sites on the albumin molecule. Conversely, more than one drug can bind to the same site. This can give rise to displacement interactions among drugs bound to the same site(s).

The hormone ADH is partly responsible for this process by controlling the amount of water the body retains from the kidney when filtering the blood stream.# Vasopressin has three main effects:> Increasing the water permeability of distal convoluted tubule & collecting duct cells in the kidney, thus allowing water reabsorption & excretion of more concentrated urine, i.e., antidiuresis. This occurs through increased transcription and insertion of water channels (Aquaporin-2) into the apical membrane of distal convoluted tubule and collecting duct epithelial cells. Aquaporins allow water to move down their osmotic gradient and out of the nephron, increasing the amount of water re-absorbed from the filtrate (forming urine) back into the bloodstream. This effect is mediated by V2 receptors. Vasopressin also increases the concentration of calcium in the collecting duct cells, by episodic release from intracellular stores. Vasopressin, acting through cAMP, also increases transcription of the aquaporin-2 gene, thus increasing the total number of aquaporin-2 molecules in collecting duct cells.> Increasing permeability of the inner medullary portion of the collecting duct to urea by regulating the cell surface expression of urea transporters, which facilitates its reabsorption into the medullary interstitium as it travels down the concentration gradient created by removing water from the connecting tubule, cortical collecting duct, and outer medullary collecting duct.> Acute increase of sodium absorption across the ascending loop of Henle. This adds to the countercurrent multiplication which aids in proper water reabsorption later in the distal tubule and collecting duct.# Drug Stimulators of Vasopressin secretion: Vincristine, cyclophosphamide, tricyclic antidepressants, nicotine, epinephrine, and high doses of morphine. Lithium, which inhibits the renal effects of vasopressin, also enhances vasopressin secretion. Inhibitors of vasopressin secretion: Ethanol, phenytoin, low doses of morphine, glucocorticoids, fluphenazine, haloperidol, promethazine, oxilorphan, and butorphanol.

As with other triazoles voriconazole impairs the biosynthesis of ergosterols by inhibiting the p450 enzyme 14a sterol demethylase. Voriconazole is administered by i.v. and oral routes. It is formulated as lyophilized powder ,for solution for i.v. infusion as well as tablets and powder for suspension for oral administration. Uses of Voriconazole Varoconazole is a broad spectrum azole. It can be used in all diseases where azoles are effective. It is especially used for ? Invasive aspergillosisQ In patients with invasive aspergillosis, initial therapy with voriconazole led to better responses and improved survival and resulted in.fewer side effects than the standard approach of initial therapy with amphotericin B. Emerging fungal pathogensQ Voriconazole is used in the primary treatment of amphotericin B and fluconazole resistant fungal infections e.g., Fusarium, Scendosporium. Patients with neutropenia and feverQ Pts with neutropenia and fever are often treated empirically with AMB or liposomal AMB to prevent invasive fungal infections. Voriconazole is a suitable alternative to AMB preparation for empirical antifungal therapy in patients with neutropenia and persistent fever. Those with Fluconazole resistant candida infection Voriconazole is a broad spectrum antifungal showing in vitro activity against candida species uncluding fluconazole resistant candida albicans2 and candida krusei2. Some impoant adverse effect of Voriconazole : ? Teratogenecity - Voriconazole is teratogenic in animals and contraindicated in pregnancy (class 0) QTc prolongation and arrhythmias - Voriconazole like some other azoles causes a prolongation of the QTc intervals which can become significant in patient with other risk factors for Torsades-de-points.", "cop": 2, "opa": "Aspergillosis", "opb": "Mucormyocosis", "opc": "Candida albicans", "opd": "Candida tropicalis", "subject_name": "Pharmacology", "topic_name": null, "id": "8cd5848d-67f9-470d-a441-002593d66378", "choice_type": "single"}

{"question": "Digoxin increases cardiac contractility by directly engaging in wof", "exp": "Mechanism of action:- Digoxin increases force of cardiac contraction by a direct action independent of innervation. It selectively binds to extracellular face of the membrane associated Na+K+ ATPase of myocardial fibres and inhibitis this enzyme. Inhibition of this cation pump results in progressive accumulation of Na+ intracellularly. This indirectly results in intracellular Ca2+ accumulation. During depolarization Ca2+ ions enter the cell driven by the steep Ca2+ gradient through voltage sensitive L type Ca2+ channels. This triggers release of larger amount of Ca2+ stored in sarcoplasmic reticulum (SR) through Ryanodine calcium channel 2 (RYR2) - cytosolic Ca2+ increases transiently (calcium transients) - triggers contraction by activating troponin C on myofibrils.

Maximum action is exeed at S phase, but toxicity is usually exhibited in G2 phase. Adverse effects:- It produces cardiotoxicity as a unique adverse effect. This can manifest either acutely within 2-3 days, causing ECG changes, arrhythmias and hypotension, all of which are reversible; or be delayed--congestive hea failure (related to the total dose administered). CHF is due to cardiomyopathy and may be fatal. Marrow depression, alopecia, stomatitis, vomiting and local tissue damage (on extravasation) are other adverse effects.

(ii) Acquired resistance In these cases the cancers were initially drug sensitive and became drug resistant, later on in the course of therapy. It can be :- Single drug resistance Cancer is resistant to a single drug and is based on change in genetic apparatus of a given tumour cell.

P glycoprotein is a protective mechanism possessed by normal cells. Pgp is an ATP dependent membrane efflux pump. Its function is to expel a variety of foreign molecules including antitumour drugs from the cell. Long lived cells such as the haemopoietic stern cells, cells on excretory surfaces such as biliarr hepatocytes, proximal renal tubules and intestinal cells and the cells of the blood- brain barrier, all have high expression of Pgp.

{"question": "Nitrates are not used in", "exp": "Renal colic The main pharmacological action of Nitrates Nitroglycerine relaxes all types of smooth muscle irrespective of the state of the preexisting muscle tone. The most prominent action is exeed on the vascular smooth muscle. - Apa .from vascular smooth muscle nitrates also cause relaxation of the smooth muscles of the bronchi, gastrointestinal tract (including biliary system) and genitourinary tract. Nitrates are rapidly denitrated in the smooth muscle to release nitric oxide which activates cytosolic guanyl cyclase which in turn increases CGMP that leads to vasodilation Effect of nitrate on cardiovascular system Enzymes activates Nitrates --4 NO --> Gyanylcyclase 1' CGMP Vasodilation Nitrates cause relaxation of all the components of vascular system from large aeries to veins, aerioles and capillaries. Veins respond at the lowest concentrations and aeries at slightly higher one (Veins express greater amount of the enzyme that generates NO )from organic nitrates). The primary direct result of an effective dose of nitroglycerine is marked relaxation of veins with increased venous capacitance and decreased ventricular preload. This leads to reduction in pulmonary vascular pressure and hea size. Effect of nitrates on coronary circulation '* In normal subjects without coronary disease - Nitroglycerine can induce a significant if transient increase in total coronary blood flow. In patients with angina due to atherosclerosis - There is no evidence that total coronary .flow is increased in patients with angina due to atherosclerotic obstructive coronary aery disease. However, in these patients - Nitrates cause redistribution of coronary blood flow from normal to ischemic regions which may play role in therapeutic effect. There are two types of vessels in coronary circulation :Larger conducting aeries They run epicardially and send perforating branches to deeper tissue. Smaller resistance vessels These are the perforating branches of larger conducting aeries. These aerioles supply blood to endocardium. If there is ischemia in any region of endocardium the perforating vessels of those region are dilated due to autoregulation (hypoxia causes vasodilation). Nitrates preferentially dilates larger conducting vessels. This pattern of action ours more blood flow towards the ischaemic zone as the smaller endocardial vessels are already dilated as a result of hypoxia / ischaemia. Nitrates in hea failure Nitrates afford relief by causing venous pooling of blood. - Nitrates reduce venous return (preload) decreases end diastolic volume -4 improvement in left ventricular function by Laplace law regression of pulmonary congestion. Nitrates are used in cyanide poisoning Cyanide poisoning results from complexing of cytochrome iron by the CV ion. - Methemoglobin has a very affinity for CN ion. - Methemoglobin combines with CN to form cyamnethemoglobin which is rapidly excreted by the body. It is a well known fact that Nitrates generate generate Methemoglobin when they combine with Hb. - Thus administration of nitrates will generate large amount of methemoglobin. - Due to its high offinity.for cyanide, methemoglobin combines with cyanide .forming cyanmethemoglobin. - This will regenerate active cytochrome. - However this may again dissociate to release cyanide. - The cynamethemoglobin can be fuher detoxified by the intravenous administration of sodium thiosulfate. This results in formation of thiocyanate ion a less toxic ion that is readily excreted. Biliary colic Esophageal spasm Sublingual GIN promptly relieves pain. Nitrates taken before a meal facilitate feeding in esophageal achalasia by reducing esophageal tone. Also remember these impoant propeies of Nitrates. Oral availability of Nitrates is low The liver contains a high capacity organic nitrate reductase that removes nitrate groups in a stepwise _fashion from the parent molecule and ultimately inactivates the drug. Therefore oral bioavailability of the traditional organic nitrates e.g. nitroglycerine and isosorbidedinitrate is very low. For this reason sublingual route is preferred for nitrates. Nitroglycerine and isosorbide dintrate are both absorbed effectively by this route and reach therapeutic blood levels within a few minutes. Nitrates develop tolerance With continued exposure smooth muscles develop tolerance to nitrates. The mechanism by which tolerance develops are not completely understood. As noted above diminished release of nitric oxide resulting from depletion of tissue thiol compounds may be paly responsible ,for tolerance to nitrates. Some student argue that cyanide poisoning should be the answer because nitrites not nitrates are used in cyanide poisoning but we are not convinced. All the standard books group them together and do not differentiate between nitrates or nitrites. More so Nitrates have'nt found wide clinical use in Renal colic - None of the standard text books mention use of nitrates in renal colic. - Both Goodman Gilman and KDT says that unlike its consistent effect on muscles of biliary tract, the action of nitrates on ureteric muscles is variable therefore it has not found application in renal colic. - None of the studies and research papers convincingly state that nitrates should be used in renal colic. Nitrates have been anecdotally used only in uruguay to treat renal colic. A trial was conducted based on this but it did'nt come out with conclusive results. - It states that large trials and studies should be undeaken before nitrates before nitrates use is begun clinically.", "cop": 3, "opa": "CCF", "opb": "Esophageal spasm", "opc": "Renal Colic", "opd": "Cyanide poisoning", "subject_name": "Pharmacology", "topic_name": null, "id": "7ce2dcb0-8de4-47b7-9d96-e9bbfb0fc3ce", "choice_type": "single"}

Instead, drug usage reflects longevity of use without obvious harm to the fetus. Hence methyldopa is still the drug of choice for many obstetricians.

Parenteral hydralazine is reserved for emergency reduction of blood pressure in late pregnancy, preferably in combination a b blocker to avoid unpleasant tachycardia (labetalol and atenolol) are often effective and probably the drug of choice in the third trimester. There is anecdotal evidence to suggest growth retardation with b blockade used in first and second trimester. Diuretics reduce the chance of developing preeclampsia but are avoided in pre-eclampsia itself because these patients, already have a contracted circulatory volume. Spironolactone is a diuretic which is avoided in pregnancy because of its antiandrogenic effect on fetus.

The precise mechanism by which opioids can cause muscular rigidity is not clearly understood. Muscle rigidity is not due to direct action on muscle fibres because it can be decreased or prevented by pretreatment with muscle relaxants. In addition, opioid induced muscle rigidity is not associated with increase in creatinine kinase a .finding suggesting that little or no muscle damage occurs during this period. - Opioids do not have any significant effect on neuromuscular conduction and result in only minimal depression of monosynaptic reflexes associated with muscle stretch receptors. - Some investigators have suggested that opioids produce rigidity by altering dopamine concentrations within the striatum.s of the brain. Rigidity may occur due to the result of stimulation of GABA ergic interneurons which can be blocked by lesion in the striatum. Continuous research and data seems to indicate that the main mechanism responsible for opioid induced muscle rigidity is stimulation of it receptors. - Opioids appear to produce their physiological effects by.binding to at least three types of opioid receptors the mu (p), delta (8) and Kappa (x) receptors. - Muscle rigidity occurs after administration of supra analgesic doses of potent p preferring opioids. - The present data demonstrates that whereas systemic opiate induced muscle rigidity is primarily due to the activation of central mu receptors, supraspinal delta and kapp receptors may attenuate this effect.

HIV and anti TNF- a therapy As of now there are only eight patients treated with HIV and Rheumatoid disease. Retrospective series of eight patients suggests that treatment with anti TNF- a therapy can be used in HIV patients without advanced disease with associated rheumatic diseases. HCV and anti TNF-- cc therapy Anti TNF- a therapy is safe in patients with HCV and Rheumatoid ahritis. In a study involving 31 patients with RA with concomitant HCV infection, TNF a blocker seemed to be safe provided there is close monitoring of clinical virological data. Pulmonary fibrosis and anti TNF- a therapy Anti TNF-a therapy is considered safe in patients with Rheumatoid ahritis and pulmonary fibrosis. In some cases pulmonary. fibrosis seems to have improved with anti-TNF- atherapy.", "cop": 2, "opa": "RA with HIV", "opb": "RA with Hepatitis B", "opc": "RA with HCV", "opd": "RA with pulmonary fibrosis", "subject_name": "Pharmacology", "topic_name": null, "id": "f7e5d78e-8c7b-4acb-989e-9aff47271f45", "choice_type": "single"}

Impaired Polyglutammation The polyglutammated.forms of methotrexate inhibits dihydrofolate reductase. The intracellular content of polyglutammate derivatives of methotrexate is controlled by a balance between folypolyglutamate synthetase and glutamyl hydrolase activity. Folypolyglutamate synthetase produces polyglutammate while A glutamyl hydrolase conves its bact to monoglutamate form A lower content of methotrexate polyglutamate could he due to decreased synthesis or an increased catabolism of methotrexate polyglutamates by A glutamate hydrolase.

{"question": "Increased prolactin is associated with aEUR'", "exp": "Increased estradial Prolactin is a polypeptide produced by the lactotrophs of the pituitary. It is responsible .for the initiation and maintenance of lactation. As with several pituitary hormones, prolactin is secreted in a circadian, fashion with the highest levels being attained during sleep and a nadir occurring between 10 am and noon. Prolactin is secreted in a pulsatile .fashion, the amplitude and frequency of which not only varies throughout the day but is also impacted upon by a variety of physiology stimuli i.e., suckling, stress and increased level of ovarian steroids primarily estrogens. \"The general view is that lactotrophs have spontaneously high secretary activity\". Therefore pituitary prolactin secretion is under a tonic and predominantly inhibitory control exeed by the hypothalamus. - Hypothalmus releases prolactin inhibitory factor (PIF) which inhibits prolactin release. - PIE is actually dopamine and it suppresses prolactin synthesis and secretion by means of D2 receptors. - These actions constitute the physiologic basis of therapeutic effect of dopamine agonists in hyperprolactinemia. Prolactin acts on the breast tissue where in the setting of estrogen priming, it stimulates lactation. Effect of physiological hormones on prolactin secretion Glucocoicoids seem to have an inhibitory role on PRL secretion. - These hormones stimulate the differentiation of somatotrophs but suppress that of lactotrophs. - Long-term elevation of the serum glucocoicoid levels by chronic administration of coicotrophin (ACTH) or hydrocoisone or by prolonged stress decreases PRL secretion. Estrogens and thyroid hormones have opposite effects on PRL synthesis and release. - \"Estrogen increases prolactin levelQ by acting at both pituitary and hypothalamic level\" - At pituitary level it increases prolactin secretion by controlling PRL gene expression and modifying its sensitivity to physiological stimuli. - At hypothalamic level it inhibits the activity of all three types of hypothalamic neuroendocrine dopaminergic neurone. - Low thyroxine (T4) and triiodothyronine (T3) levels increase TRH-induced PRL secretion, whereas high T4 and T3 levels inhibit PRL mRNA accumulation and release. An impoant point Increased estrogen causes hyperprolactinemia But Hyperprolactinemia causes decrease in estrogen Prolactin also acts at the hypothalamus to inhibit the secretion of gonadotropin releasing hormone (GnRH). - Inhibition of GnRH results in a decrease in the release of LH and FSH from the anterior pituitary. In females - This leads to decreased in estrogen and progesterone synthesis and secretion by the ovaries and a failure of ovarian .follicular maturation. In males - This leads to decrease in testicular production and synthesis of testosterone and a halt in spermatogenesis.

High doses of steroids or Tirilazad are thought to minimize the secondary effects of acute SCI.> 30-mg/kg bolus of methylprednisolone administered within 8 hours of injury, whereas the study evaluated methylprednisolone 5.4 mg/kg/h for 24 or 48 hours versus tirilazad 2.5 mg/kg q6h for 48 hours. (Tirilazad is a potent lipid preoxidation inhibitor.)> Between the 2 studies, it was determined that: (1) in patients treated earlier than 3 hours after injury, the administration of methyl- prednisolone for 24 hours was best; (2) in patients treated 3-8 hours after injury, the use of methylprednisolone for 48 hours was best; (3) Tirilazad was equivalent to methylprednisolone for 24 hours.> Both NASCIS studies evaluated the patients' neurologic status at baseline on enrollment into the study, at 6 weeks, and at 6 months and found absolutely no evidence suggests that giving the medication earlier (eg, in the first hour) provides more be nefit than giving it later (eg, between hours 7 and 8).> The authors concluded that there was only a benefit if methylprednisolone or tirilazad were given within 8 hours of injury.> Use of high-dose methylprednisolone in non-penetrating acute SCI had become the standard of care in North America.An increased incidence of infection and avascular necrosis has been documented.> Revised recommendations pertaining to steroid therapy in SCI:- The American College of Surgeons (ACS) has modified their advanced trauma life support (ACLS) guidelines to state that methylprednisolone is \"a recommended treatment\" rather than \"the recommended treatment.\" Updated guidelines issued in 2013 by the CNS and the American Association of Neurological Surgeons (AANS) recommend against the use of steroids early after an acute SCI. Guidelines recommend that methylprednisolone not be used for the treatment of acute SCI within the first 24-48 hours following injury. Previous standard was revised because of a lack of medical evidence supporting the benefits of steroids in clinical settings and evidence that high-dose steroids are associated with harmful adverse effects. Overall, the benefit from steroids is considered modest at best, but for patients with complete or incomplete quadriplegia, a small improvement in motor strength in one or more muscles can provide important functional gains. Administration of steroids remains an institutional and physician preference in spinal cord injury. Administration of high-dose steroids within 8 hours of injury for all patients with acute spinal cord injury is practiced by most physicians. Current recommendation is to treat all patients with spinal cord injury according to the local/regional protocol. If steroids are recommended, they should be initiated within 8 hours of injury with the following steroid protocol: Methylpred- nisolone 30 mg/kg bolus over 15 minutes and an infusion of methylprednisolone at 5.4 mg/kg/h for 23 hours beginning 45 minutes after the bolus.", "cop": 3, "opa": "15 mg/kg/body weight", "opb": "25 mg/kg/body weight", "opc": "30 mg/kg/body weight", "opd": "50 mg/kg/body weight", "subject_name": "Pharmacology", "topic_name": "Miscellaneous (Pharmacology)", "id": "0382a2af-b8f1-4c95-9eb8-9ffdd684c474", "choice_type": "single"}

It is most commonly caused by Graves disease, but autonomously functioning nodules, gestational trophoblastic disease, thyroiditis, and hyperemesis gravidarum should also be considered. Methimazole crosses the placenta to a greater degree than propylthiouracil and has been associated with fetal aplasia cutis. However, propylthiouracil can be associated with liver failure. Some experts recommend propylthiouracil in the first trimester and methimazole thereafter. Radioiodine should not be used during pregnancy, either for scanning or treatment, because of effects on the fetal thyroid. In emergent circumstances, additional treatment with beta blockers and a saturated solution of potassium iodide may be necessary.

When the time to reach steady state is long, as it is for drugs with long half-lives and having high volume of distribution (Vd) due to their tissue affinities, it may be desirable to administer a large dose (loading dose) to achieve the desired plasma levels rapidly. The volume ot distribution is the proportionality factor that relates the total amount of drug in the body to the concentration in the plasma (Cp).LOADING DOSE= Vd X Desired steady state plasma concentrationLoading dose can be given as single dose or multiple doses over a short time. E.g. in case of treatment of AF by digoxin (longer acting drug with high Vd), loading dose is must to saturate the tissues and to achieve desired plasma concentration rapidly (otherwise it would take about a week for digoxin to achieve the steady state plasma concentration). Loading dose of Chloroquine is also required to treat the malaria.On the other hand, maintenance dose is dependent of the clearance (Cl) as we have to maintain the steady state concentration in view of the volume of the plasma cleared of drug per unit time. Hence, equation for maintenance dose isMAINTENANCE DOSE= Cl X Desired steady state plasma concentration", "cop": 1, "opa": "Volume of distribution", "opb": "Clearance", "opc": "Half life", "opd": "bioavailability", "subject_name": "Pharmacology", "topic_name": "General Pharmacology", "id": "d746203f-d228-428c-8e11-06df6ca4c7a6", "choice_type": "single"}

{"question": "Mechanism of action of disgitalis is", "exp": "Digoxin's primary mechanism of action involves inhibition of the sodium potassium adenosine triphosphatase (Na+/K+ ATPase), mainly in the myocardium. This inhibition causes an increase in intracellular sodium levels, resulting in decreased activity of the sodium-calcium exchanger, which normally impos three extracellular sodium ions into the cell and transpos one intracellular calcium ion out of the cell. The reversal of this exchanger causes an increase in the intracellular calcium concentration that is available to the contractile proteins. Increased intracellular calcium lengthens phase 4 and phase 0 of the cardiac action potential, which leads to a decrease in hea rate. Increased amounts of Ca2+ also leads to increased storage of calcium in the sarcoplasmic reticulum, causing a corresponding increase in the release of calcium during each action potential.

{"question": "Oral vancomycin is indicated in the following condition", "exp": "GLYCOPEPTIDE ANTIBIOTICS Vancomycin Mech of action:- Vancomycin acts by inhibiting bacterial cell wall synthesis. It binds to the terminal dipeptide 'D-ala-D-ala' sequence of peptidoglycan units-- prevents its release from the bactoprenol lipid carrier so that assembly of the units at the cell membrane and their cross linking to form the cell wall cannot take place. pharmacokinetics:- Vancomycin is not absorbed orally. After i.v. administration, it is widely distributed, penetrates serous cavities, inflamed meninges and is excreted mainly unchanged by glomerular filtration with a t 1/2 of 6 hours. Dose reduction is needed in renal insufficiency. Toxicity:- Systemic toxicity of vancomycin is high. It can cause plasma concentration dependent nerve deafness which may be permanent. Kidney damage is also dose-related. Other oto- and nephrotoxic drugs like aminoglycosides must be very carefully administered when vancomycin is being used. Skin allergy and fall in BP during i.v. injection can occur. Vancomycin has the potential to release histamine by direct action on mast cells. Rapid i.v. injection has caused chills, fever, uicaria and intense flushing-- called 'Red man syndrome'.

Harrison 16thie p 4781 CML is characterized by the presence of a distinctive molecular abnormality namely philadelphia chromosome. Philadelphia chromosome in formed as a result of reciprocal translocation between long arm of chromosome 22 and chromosome 9 i.e. t (9 ; 22). ABL protooncogene from chromosome 9 is translocated to chromosome 22 where BCR is present and results in formation of BCR-ABL fusion chimeric gene. The drug imatinib mesylate is a BCR-ABL tyrosine kinase signal transduction inhibitor. This drug acts as a inhibitor of the ATP binding site on the protein and prevents its phosphorylation and thus its activity. An impoant point CML is caused by reciprocal translocation between BCR and ABL gene located on chromosome 9 and 22. Imatinib mesylate does not block this translocation i.e., BCR ABL translocation. - Instead, it blocks the constitutive abnormal tyrosine kinase, BCR-ABL that is created by the Philadelphia chromose (BCR-ABL). - The drug inhibits the proliferation and induces apoptosis in BCR-ABL positive cells. Also know Protein tyrosine kinase inhibitors Protein kinases are ubiquitous and critical components of signal transduction pathways that transmit information concerning extra cellular or cytoplasmic conditions to the nucleus, thereby influencing gene transcription and/or DNA synthesis. The protein kinases can be classified into three categories: (i) Tyrosine kinase (ii) Serine threonine kinase (iii) Kinases with activity for all three residues Abnormal activation of specific tyrosine kinase has been demonstrated in many human neoplasms. Thus they can be targeted in ceain cancer therapies. There currently are three small-molecular weight protein tyrosine kinase inhibitors that are FDA approved and many others are in clinical trials. i) Imatinib Imatinib has efficacy in diseases in which the ABL, KIT or PDGFR have dominant roles in driving the proliferation of the tumour. Thus, imatinib shows remarkable therapeutic benefits in patients with - CML (BCR-ABL) - GIST (KIT mutation positive) - CMML (EVT6-PDGFR) ii) Gefitinib The epidennal growth factor receptor (EGFR) belongs to the family of tyrosine kinase. Gefitinid is a specific inhibitor of the EGFR tyrosine kinase that competitively inhibits ATP binding. EGFR is overexpressed in non-small cell carcinoma of lung, thus Gefitinib has been approved for use in non-small cell carcinoma. iii) Erlotinib It is a human HERI/EGFR tyrosine kinase inhibitor.

{"question": "Drug that can be used for producing alkalinization of urine is", "exp": "CARBONIC ANHYDRASE INHIBITORS Carbonic anhydrase is an enzyme which catalyses thereversible reaction H2O+CO2 -> H2CO3. Carbonic acid spontaneously ionizes H2CO3 -> H+ + HCO3-. Carbonic anhydrase thus functions in CO2 and HCO3 - transpo and in H+ ion secretion. The enzyme is present in renal tubular cell (especially PT) gastric mucosa, exocrine pancreas, ciliary body of eye, brain and RBC. Acetazolamide:- Mech of action:- It is a sulfonamide derivative which noncompetitively but reversibly inhibits CAse (type II) in PT cells resulting in slowing of hydration of CO2 ->decreased availability of H+ to exchange with luminal Na+ through the Na+-H+ antipoer. Inhibition of brush border CAse (type IV) retards dehydration of H2CO3 in the tubular fluid so that less CO2 diffuses back into the cells. The net effect is inhibition of HCO3 - (and accompanying Na+) reabsorption in PT.

{"question": "SERM drug used in treatment of osteoporosis aEUR'", "exp": "Raloxifene Traditionally hormone replacement therapy with estrogen was being used to prevent/treat osteoporosis in postmenopausal worsen. H has been shown to reduce the risk of osteoporosis in women. But long term use of estrogen leads to range of adverse effect including cardiovascular disease, stroke, pulmonary emboli and invasive breast cancer. These serious adverse effect made to look for other options. Selective estrogen receptor modulators These are class of compounds that act on estrogen receptors. Their characteristic feature is that they do not have pure agonist or antagonistic action on estrogen receptors. - Their selective action distinguishes these substances .from pure receptor agonist or antagonist. - SERMS are \"selective\" that means SERMS block estrogen in some tissues and activate estrogen action in others. - All the SERMS bind to the estrogen receptor but each agent produces a unique receptor drug conformation. - As a result specific coactivator or co-oppressor proteins are bound to the receptor resulting in differential effects. Two SERMS are currently being used Raloxifens For the t/t and prevention of osteoporosis Tamoxifen --> For the t/t and prevention of Breast Ca The .first SERM to reach the market was Tamoxifen which blocks the stimulative effect of estrogen on breast tissue and is used in breast cancer. Raloxifene is the second SERM to be approved by the FDA. Raloxifens has been approved for the tit and prevention of osteoporosis in postmenopausal women. Raloxifens acts like estrogen on bone and helps to build and maintain bone density. - Raloxifen has been shown in clinical trials to increase bone density in the spine and hip and to reduce the risk of spinal fractures in women with osteoporosis. While it acts like estrogen on bone, it blocks the action of estrogen on breast and uterus. - This profile makes it very useful for the t/t of osteoporosis because Raloxifene provides the bone benefits of estrogen without increasing the risk for estrogen related breast and uterine cancers. Raloxifene in Breast cancer Due to its antiestrogenic effect on breast, Raloxifene has been shown to reduce the risk of invasive breast cancer in women who are taking it for osteoporosis. Raloxifene reduces the risk of breast cancer by 50-70% in both low risk and high risk postmenopausal women. The national cancer institute U.S.A. funded the STUDY OF TAMOXIFEN AND RALOXIFEN (STAR) a clinical trial comparing raloxtfens with tamoxifen in preventing breast cancer, in postmenopausal women who are at increased risk of developing the disease. The study found that tamoxifen and Raloxifen are equally effective in reducing invasive breast cancer risk in postmenopausal women who are at increased risk of the disease. The study also .found out that women who took raloxifen had fewer uterine cancer and.fewer blood clots than women who took tamoxifen. However, Raloxifen did not decrease the risk of noninvasive breast Ca.
