VISKEN® Novartis Pharmaceuticals Pindolol Antihypertensive – Antianginal Action And Clinical Pharmacology: Pindolol is a beta-adrenergic-receptor-blocking agent which possesses partial agonist activity (intrinsic sympathomimetic activity – I.S.A.). Hypertension: The mechanism of the antihypertensive effect of pindolol has not been established. Among the factors that may be involved are: competitive ability to antagonize catecholamine-induced tachycardia at the beta-receptor sites in the heart, thus decreasing cardiac output; a reduction in total peripheral resistance;…

VIROPTIC® Glaxo Wellcome Trifluridine Topical Antiviral Action And Clinical Pharmacology: Trifluridine is phosphorylated by a cellular thymidine kinase to its nucleotide monophosphate. Trifluridine monophosphate is an inhibitor of thymidylate synthetase, the target enzyme for the action of monofluorinated pyrimidines. Trifluridine has been demonstrated to combine slowly and irreversibly with thymidylate synthetase in a reaction that requires ATP. Trifluridine monophosphate is further phosphorylated by cellular enzymes to the triphosphate which is…

VISKAZIDE® Novartis Pharmaceuticals Pindolol – Hydrochlorothiazide Antihypertensive Action And Clinical Pharmacology: Viskazide contains the antihypertensive activity of 2 agents: a beta-adrenergic receptor blocking agent (pindolol) and a diuretic (hydrochlorothiazide). Pindolol is a nonselective beta-adrenergic receptor blocking agent which possesses partial agonist activity (intrinsic sympathomimetic activity-ISA). The mechanism of the antihypertensive effect of beta-adrenergic receptor blocking agents has not been established. Among the factors that may be involved are: (a) competitive…

VISIPAQUE™ Nycomed Imaging A.S. Iodixanol Nonionic Radiographic Contrast Medium Action And Clinical Pharmacology: Immediately following rapid intravascular injection, iodixanol reaches peak plasma concentration and is then rapidly distributed throughout the extracellular fluid compartment. It will opacify those vessels in the path of flow of the contrast medium, permitting radiographic visualization of the vasculature of the internal structures until significant dilution and elimination occurs. The degree of density enhancement is directly…

VIOKASE® Axcan Pharma Pancrelipase Oral Enzyme Therapy Action And Clinical Pharmacology: The natural digestive enzymes in Viokase hydrolyse fats into fatty acids and glycerol, split protein into amino acids, and convert carbohydrates to dextrins and short chain sugars. Under conditions of the USP test method (in vitro), Viokase has the following total digestive capacity The digestive capacity of a pancreatic enzyme concentrate depends on the amount that passes through the…

VIPRINEX® Knoll Ancrod Anticoagulant Action And Clinical Pharmacology: Ancrod, a thrombin-like enzyme obtained from the venom of the Malayan Pit Viper (Agkistrodon rhodostoma), is highly specific for fibrinogen, producing anticoagulation by defibrinogenation. Enzymatically, Ancrod cleaves fibrinogen to split off the A-fibrinopeptides (A, AY and AP), but not the B-fibrinopeptide. The resulting fibrin polymers are imperfectly formed and much smaller in size (1 to 2 m long) than the fibrin polymers…

Virazole (Lyophilized) ICN Ribavirin Antiviral Action And Clinical Pharmacology: Ribavirin is active against respiratory syncytial virus (RSV). In cell cultures, the inhibitory activity of ribavirin for RSV is selective. The mechanism(s) of action is unknown, although evidence exists that inhibition of other RNA and DNA viruses may be due to ribavirin competition with guanosine in formation of viral mRNA cap structures and/or interference with enzymes responsible for functional methylation of…
