PHARMA QUICK REVIEW


Amiloride is drug of choice for diabetes insipidus due to lithium

Thiazides can be useful in patients having renal stone due to hypercalciurea

Furosemide is the high ceiling Diuretics

Potassium sparing Diuretics cause hyperkalemia if given with ace inhibitors

thioazides are doc for hypertension as they act slowl and conserve calcium

mc side efects of both thiazides and furosemide is hypokalemia




mc mode of drug absorption is passive diffusion

vd volume of distribution =amount/plasma concentration

clearence is the volume of plasma that gets filterd of the drug in unit time

clearence is rate of elimination/plasma concentration

both halflife and CL remains constant in first order kinetics while both change in zero order kinetics

a drug is eliminated completely in 4-5 half-lives

dose response curve is relationship btwn log of dose and response

slope indicates safety;hight indicates efficacy;x axis indicates potency

teratogens are drugs that cause teratogenicity;thalidomide is most potent teratogen

bio-availability depends upon absorption and first pass metabolism;it is 100% by i.v route

vd determines the loading dose and CL determines the maintenece dose

zero order kinetic drugs:phenytoin,warfarin,theophilin,alcohol

efficacy is more important than safety



hypokalemia is mc precipitating factor of digoxin toxicity

spiraolactone is doc for refractor ascities ;mc sideeffect is hyperkalemia

amiloride,triamterene are other k+sparing diuretics

manitol is osmotic diuretic & doc for brain edema

demeclocycline & lithium are adh receptor agonists,used in syndrome of inappropriate adh secretion

loop diuretics are effective in renal failure whereas thiazides are effective

loop diuretics cause hypocalcemia whereas thiazides cause hypercalcemia

carboic anhydrase inhibitors like acetazolamide cause maximum excretion of potassium

. Drug not interferes with antacid( Azithromycin, Tetracyclin, Norfloxacin,Ranitidine)

. All are B-lactam inhibitors except(Astreonam, Sulbactam, Tazactam, Clavulenic acid)

. Penicillin is(safe in pregnancy, is 6 amino penicill acid, all are not antipseudomonal)

. Not used as an antacid(NaHCO3, AlOH3, SiO2, MgSO4)

. DOC in LGV- Tetracycline

. Lactic acidosis in DM therapy caused by – Phenformin

. Pancreatitis is a S/E of( Didanosine, Zidovudine,Zalcitabine)

. B-blockers are used in all except( A-V block, angina, FAMILIAL TREMOR
