LONITEN® Pharmacia & Upjohn Minoxidil Antihypertensive Action And Clinical Pharmacology: Minoxidil is an orally effective direct acting peripheral vasodilator that reduces elevated systolic and diastolic blood pressure by decreasing peripheral vascular resistance. Minoxidil does not directly stimulate the heart or electrolyte reabsorption by the kidney. However, because of peripheral dilatation, minoxidil elicits a reflex mediated increase in cardiac output, salt and water retention, and a rise in plasma renin activity….

LOMOTIL® Searle Diphenoxylate HCl – Atropine Sulfate Antidiarrheal Action And Clinical Pharmacology: The mode of action of diphenoxylate in the bowel is similar to that of morphine and related drugs. Gastrointestinal propulsion is inhibited through a direct action on the smooth muscle, resulting in a decrease in peristaltic action and a consequent increase in transit time. tag_IndicationsIndications Indications And Clinical Uses: As an adjunct in the management of diarrhea. Bacterially-induced…

LEVOPHED® Sanofi Norepinephrine Bitartrate Sympathomimetic Action And Clinical Pharmacology: Norepinephrine functions as a powerful peripheral vasoconstrictor (alpha-adrenergic action) and as a potent inotropic stimulator of the heart and dilator of coronary arteries (beta-adrenergic action). Both of these actions result in an increase in systemic blood pressure and coronary artery blood flow. Cardiac output will vary reflexly in response to systemic hypertension but is usually increased in hypotensive man when the…

LECTOPAM® Roche Bromazepam Anxiolytic – Sedative Action And Clinical Pharmacology: Bromazepam is a benzodiazepine with anxiolytic and sedative properties which are of value in the symptomatic relief of pathological anxiety in psychoneurotic patients. The absolute bioavailability of unchanged, orally administered bromazepam is 60%, and peak blood levels are achieved within 2 hours after administration. On average, 70% of bromazepam is bound to plasma proteins. Bromazepam is metabolized in the liver,…

exoLERITINE® Injection LERITINE® Tablets Frosst Anileridine Phosphate Anileridine HCl Opioid Analgesic Action And Clinical Pharmacology: Anileridine, a synthetic opioid, is a strong analgesic. The chief pharmacologic action is exerted on the CNS. The analgesic effects usually are prompt in onset either orally or parenterally (approximately within 15 minutes). Duration of action is about 2 or 3 hours. Respiratory depression, when it occurs, is of shorter duration than that seen with…

LANVIS® Glaxo Wellcome Thioguanine Antileukemic Agent Action And Clinical Pharmacology: Thioguanine is a close relative of mercaptopurine and like the latter is an antimetabolite which blocks purine metabolism. It causes depletion of human bone marrow producing neutropenia, reticulopenia, anemia, thrombocytopenia, and prolongation of clotting time. The protracted but reversible aplasia of bone marrow closely resembles the effects of ionizing radiations. In man, thioguanine is extensively converted to 2-amino-6-methyl-mercaptopurine which is…

LARIAM® Roche Mefloquine HCl Antimalarial Agent Action And Clinical Pharmacology: Mefloquine acts on the asexual intraerythrocytic forms of the human malaria parasites: P. falciparum, P. vivax, P. malariae and P. ovale. Mefloquine is also effective against malaria parasites resistant to other antimalarials such as chloroquine, proguanil, pyrimethamine and pyrimethamine-sulfonamide combinations. Resistance to P. falciparum to mefloquine has been reported, mainly in parts of South-East Asia. Cross-resistance between mefloquine and halofantrine…

LASIX® SPECIAL Hoechst Marion Roussel Furosemide Diuretic Action And Clinical Pharmacology: Animal experiments using stop-flow and micropuncture techniques have demonstrated that furosemide inhibits sodium reabsorption in the ascending limb of Henle’s loop as well as in both proximal and distal tubules. The action of furosemide on the distal tubule is independent of any inhibitory effect on carbonic anhydrase or aldosterone. The diuretic effect of furosemide is exerted even when glomerular…
