ARALEN® Sanofi Chloroquine Phosphate Antimalarial – Antiparasitic Action And Clinical Pharmacology: Chloroquine has been found to be highly active against the erythrocytic forms of Plasmodium vivax, ovale and malariae and many strains of Plasmodium falciparum (but not the gametocytes of Plasmodium falciparum). The precise mechanism of plasmodicidal action of the drug is not known. While the drug can inhibit certain enzymes, its effect is believed to result, in part, from…

AQUACORT® Spectropharm Dermatology Hydrocortisone Topical Corticosteroid Action And Clinical Pharmacology: Topical corticosteroids are synthetic derivatives of cortisone which are effective when applied locally to control many types of inflammatory, allergic and pruritic dermatoses. They are thought to act by controlling the rate of synthesis of proteins. The primary action of the corticosteroid is to interfere with the synthesis of arachidonic acid by inhibiting the phospholipase A2 synthesis. The overall effect…

APO®-TERAZOSIN Apotex Terazosin HCl Antihypertensive Agent – Symptomatic Treatment of Benign Prostatic Hyperplasia (BPH) Action And Clinical Pharmacology: Hypertension: The antihypertensive effect of terazosin is believed to be a direct result of peripheral vasodilation. Although the exact mechanism by which the lowering of blood pressure is achieved is not known, the relaxation of the vessels appears to be produced mainly by selective blockade of a1-adrenoceptors. Benign Prostatic Hyperplasia (BPH): The…

APO®-OFLOX Apotex Ofloxacin Antibacterial Action And Clinical Pharmacology: Ofloxacin is a broad-spectrum, synthetic fluoroquinolone antibacterial agent for oral administration. Ofloxacin is thought to exert a bactericidal effect on susceptible bacterial cells by inhibiting the essential bacterial enzyme DNA gyrase, a critical catalyst in the duplication, transcription and repair of bacteria. The bioavailability of ofloxacin in the tablet formulation is approximately 98%. Ofloxacin is rapidly and completely absorbed from the upper…

APO®-TICLOPIDINE Apotex Ticlopidine HCl Inhibitor of Platelet Function Action And Clinical Pharmacology: Ticlopidine is an inhibitor of platelet aggregation. It causes a time and dose-dependent inhibition of platelet aggregation and release of platelet factors, as well as prolongation of bleeding time. The drug has no significant in vitro activity. The exact mechanism of action is not fully characterized, but does not involve inhibition of the prostacyclin/thromboxane pathways or platelet cAMP….

APO®-DOMPERIDONE Apotex Domperidone Maleate Modifier of Upper Gastrointestinal Motility Action And Clinical Pharmacology: Domperidone is a peripheral dopamine antagonist structurally related to the butyrophenones with antiemetic and gastroprokinetic properties. Domperidone effectively increases esophageal peristalsis and lower esophageal sphincter pressure (LESP), increases gastric motility and peristalsis, enhances gastroduodenal coordination and consequently facilitates gastric emptying and decreases small bowel transit time. The mechanism of action of domperidone is related to its peripheral…

APO®-ETODOLAC Apotex Etodolac Anti-inflammatory Action And Clinical Pharmacology: Etodolac is a nonsteroidal anti-inflammatory drug (NSAID) that exhibits anti-inflammatory, analgesic and antipyretic properties in animal models. The pharmacological actions of etodolac are thought to be related to inhibition of prostaglandin biosynthesis at the site of inflammation. Etodolac is a racemic mixture of R- and S-etodolac. As with other NSAIDs, it has been demonstrated in animals that the S-form is biologically active…

APO®-KETOCONAZOLE Apotex 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. The…
