Drug Names and Classifications (Diureticss, Anti-platelets) Flashcards
Mannitol
Osmotic diuretic; working on proximal tubule; becomes filtered into urea and drags water into urine with it
Mostly used to maintain acute renal failure
Glyerol
Osmotic diuretic; freely filtered into urine and increases the volume.
Safer and less effective than Mannitol
Has a caloric value
Acetalzolamide (Diamox)
Prototypical carbonic anhydrase inhibitor; sulfa drug
Taken orally
Dorzolamide (Trusopt)
Carbonic Anhydrase Inhibitor; topical, used in the eye for IOP.
Can be used off label for treatment of acute mountain sickness by causing acidosis (drives respiration which is helpful in elevated climates)
Hydrochlorothiazide (HydroDiuril)
Prototypical thiazide drug; sulfa drug; distal tubule, blocking sodium/chloride symport
Indapamide (Lozol)
Thiazide drug; sulfa drug; distal tubule, blocking sodium/chloride symport
Chlorthalidone (Hygroton)
Thiazide drug; sulfa drug; distal tubule, blocking sodium/chloride symport
Furosemide (Lasix)
Prototypical loop diuretic; sulfa; blocks Na/Cl/K co-transport in thick ascending loop of Henle, losing the NaCl and K to the urine
Bumetanid (Bumex)
Prototypical loop diuretic; sulfa; blocks Na/Cl/K co-transport in thick ascending loop of Henle, losing the NaCl and K to the urine
Spirolactone (Aldactone)
K+ sparring diuretic; blocks aldosterone action to prevent Na/K exchange in late distal tubule to conserve.
Triamterene (Dyrenium)
K+ sparring diuretic; directly blocks Na/K exchange in late distal tubule to conserve
Few toxicities, but do not use while on potassium supplement
Quinidine
Class I Anti-arrhythmic; blocks Na channel to hyperpolarize and slow impulses.
Disopyramide (Norpace)
Class IA Anti-arrhythmic; Like quinidine, a sodium and some potassium block to slow heart.
Metabolized into an active product
Lidocaine (Xylocaine)
Class IB anti-arrhythmic; blocks active and inactive sodium channels rapidly and highly effective at treating ventricular fibrillation
Also used for ventricular arrhythmias and myocardial infarct
Contraindicated in epilepsy and liver disease
Flecainide (Tambocor)
Class IC anti-arrhythmic; maximal depression of phase 0, extremely powerful sodium channel blocker
Propranolol (-olol)
Beta blocker (Class II); blocks adrenergic (beta) activity, especially good at treating arrhythmia due to excess sympathetic tone
Sotalol
Class II with some potassium blocking
Amiodarone (Cordarone)
Class III anti arrhythmia; increases duration of action potential
Used in cases of severe resistant arrhythmia
Verapamil (Isoptin)
Class IV anti-arrhythmia; calcium channel blocker; blocks calcium influx in SA/AV node to prevent depolarization
Diltiazam
Class III anti-arrhythmic; calcium channel blocker; not as selective as verapamil and more issues with hypotension
Heparin
Indirect acting Anti-coagulant; must work in the presence and on Anti-Thrombin III; enhances ability to block factor Xa
Warfarin
Prototypical vitamin K antagonist; competitive with vitamin K and disrupts coagulation factor synthesis.
Active only in vivo
Dabigatrin (Pradaxa)
Active thrombin inhibitor; inhibits thrombin (active factor IIa)
Aspirin
NSAID; but is a really, really good anti-platelet drug; affects COX-1 and COX-2 and disrupts prostaglandins
Classic toxicity is GI upset/ulcer
