NORLUTATE® Parke-Davis Norethindrone Acetate Progestational Agent Action And Clinical Pharmacology: Norethindrone acetate differs from norethindrone only in potency; the acetate is approximately twice as potent. Transforms proliferative endometrium into secretory endometrium. Inhibits (at the usual dose range) the secretion of pituitary gonadotropins, which in turn prevents follicular maturation and ovulation. May also demonstrate some estrogenic, anabolic or androgenic activity but should not be relied upon. Indications And Clinical Uses: Amenorrhea;…

NORCURON® Organon Vecuronium Bromide Nondepolarizing Neuromuscular Blocking Agent Action And Clinical Pharmacology: Vecuronium is a nondepolarizing neuromuscular blocking agent possessing all of the characteristic curariform pharmacological actions of this class of drugs. It acts by competing for cholinergic receptors at the motor end-plate. The antagonism to acetylcholine is inhibited and neuromuscular block is reversed by acetylcholinesterase inhibitors such as neostigmine, edrophonium, and pyridostigmine. Vecuronium is about a third more potent…

NIX® Dermal Cream Glaxo Wellcome Permethrin Topical Scabicide Action And Clinical Pharmacology: Permethrin is a synthetic pyrethroid, which is active against a broad range of pests including lice, ticks, fleas, mites, and other arthropods. It acts on the nerve cell membrane to disrupt the sodium channel current by which the polarization of the membrane is regulated. Delayed repolarization and paralysis of the pests are the consequences of this disturbance. Lag…

NIZORAL® Shampoo McNeil Consumer Products Ketoconazole Topical Antifungal Action And Clinical Pharmacology: In vitro studies suggest that the antifungal properties of ketoconazole may be related to its ability to impair the synthesis of ergosterol, a component of fungal and yeast cell membranes. Without the availability of this essential sterol, there are morphological alterations of the fungal and yeast cell membranes manifested as abnormal membranous inclusions between the cell wall and…

NIZORAL® Tablets Janssen-Ortho Ketoconazole Antifungal Action And Clinical Pharmacology: In vitro studies suggest that the antifungal properties of ketoconazole may be related to its ability to impair the synthesis of ergosterol, a component of fungal and yeast cell membranes. Without the availability of this essential sterol, there are morphological alterations of the fungal and yeast cell membranes manifested as abnormal membranous inclusions between the cell wall and the plasma membrane….

NITROLINGUAL® PUMPSPRAY Rhône-Poulenc Rorer Nitroglycerin Antianginal Action And Clinical Pharmacology: The principal action of nitroglycerin is that of all nitrates, namely, relaxation of vascular smooth muscle. Nitrates act primarily by reducing myocardial oxygen demand rather than increasing its oxygen supply. This effect is thought to be brought about predominantly by peripheral action. Although venous effects predominate, nitroglycerin produces, in a dose-related manner, dilation of both arterial and venous beds. Dilation…
