MedChem II - stack 3

Catecholaminergic drugs part 2

Drug nameDescription
Phenoxybenzamine HCl (Dibenzyline) Adrenergic antagonist, covalently bonds to the receptor, treats pheochromacytoma
Phentolamine (Regitine) Incomplete and transient alpha-blocker, more potent than priscoline, used to treat pheochromacytoma
Priscoline (Tolazoline) Less potent incomplete and transient alpha blocker, used in persistent pulmonary hypertension in newborn infants, use with caution in patients with gastritis or peptic ulcer disease
Prazosin HCl (Minipress) Piperazinyl quinazoline alpha-antagonist, used in hypertension and benign prostatic hypertrophy
Terazosin HCl (Hytrin) Piperazinyl quinazoline alpha-antagonist, highly specific for alpha-1 receptors, more water soluble (higher bioavailability, longer half-life, and duration of action)
Doxazosin mesylate (Cardura) Piperazinyl quinazoline selective alpha-1 antagonist, treats hypertension
Afluzosin HCl (Uroxatral) Piperazinyl quinazoline selective alpha-1 antagonist, metabolized by CYP3A4, used to treat BPH
Tamsulosin HCl (Flomax) Non-piperazilyn quinazoline alpha-1 adrenergic antagonist, has a reduced incidence of vascular side effects, treats BPH, cannot be used to treat hypertension
Yohimbine Indole alpha antagonist, has alpha-2 and serotonergic antagonist activity, used to treat impotence and postural hypotension
Propranolol HCl (Inderal) Nonselective beta blocker, no sympathomimetic activity, lipophilic (CNS penetration, etc.), metabolized to naphtoxylactic acid, mainly used to treat hypertension
Nadolol (Corgard) Analogue of propranolol, nonselective beta blocker with no intrinsic sympathomimetic activity, less lipophilic, treats hypertension and chest pain
Timolol maleate opthalmic solution (Timoptic) Nonselective betea blocker, no sympathomimetic activity, lipophilic (systemic absorption), used to treat glaucoma
Timolol maleate oral (Blocadren) Combination with HCTZ (Timolide) Oral form of timolol, marketed for hypertension
Pindolol (Visken) Beta blocker with sympathomimetic activity, somewhat lipophilic, treats angina and hypertension
Labetalol HCl (Normodyne, Trandate) Nonselective beta blocker, has some alpha-1 antagonistic activity, some sympathomimetic activity, treats hypertension
Metoprolol Tartrate (Lopressor) Metoprolol Succinate (Toprol XL) Beta-1 selective antagonist, no intrinsic sympathomimetic activity, lipophilic, treats hypertension
Atenolol (Tenormin) Beta-1 selective antagonist, no intrinsic sympathomimetic activity, less lipophilic, treats hypertension
Esmolol HCl (Bevibloc) Beta-1 blocker with no intrinisc sympathomimetic activity, has a short half-life, used IV in emergencies involving atrial flutter, atrial fibrillation, or sinus tachycardia
Acebutolol HCl (Sectral) converted to Diacetolol Beta-1 selective antagonist, diacetolol is the more active compound, has a degree of sympathomimetic activity
Carvedilol (Coreg) S(-) isomer is a nonselective beta blocker, both enantiomers have alpha-blocking properties and thus vasodilatory activity, treats hypertension
Careolol (Cartrol) Penbutolol sulfate (Levatol) Nonselective beta antagonists with intrinsic sympathomimetic activity
Levobunolol HCl (Betagan) Nonselective beta blocker, used in treatment of glaucoma
Betaxolol HCl (Betopic) Beta-1 selective antagonist, used as antihypertensive and in treatment of glaucoma
Bisprolol Fumarate (Zebeta) Highly beta-1 selective antagonist, treats hypertension
Sotalol (Betapace) Nonselective beta blocker, structurally distinct from others, treats ventricular arrhythmias
Propafenone HCl (Rythmol) Weak beta blocker, has local anesthetic activity through blocking sodium ion channels, used as an antiarrhythmic
Nebivolol (Bystolic) Highly selective beta blocker (selects beta-1 over beta-2), less bronchoconstrictive effects, treats hypertension
Theophylline Aminophylline Inhibit phosphodiesterase enzyme and prevent conversion of c-AMP to 5`-AMP, cause bronchodilation
