APO®-CROMOLYN Apotex Sodium Cromoglycate Seasonal Rhinitis Prophylaxis Action And Clinical Pharmacology: In the immediate allergic reaction (Type I) the union of antigen with reaginic antibody leads to the formation and release of spasmogens and other mediators of the anaphylactic reaction. Sodium cromoglycate appears to block a step in the chain of events triggered by this union. This property accounts for the prophylactic rather than symptomatic approach to the management of…

APO®-CROMOLYN STERULES Apotex Cromolyn Sodium Asthma Prophylaxis Action And Clinical Pharmacology: In vitro and in vivo animal studies have shown that cromolyn sodium inhibits sensitized mast cell degranulation which occurs after exposure to specific antigens. It acts by inhibiting the release of mediators from mast cells. Studies show that cromolyn sodium indirectly blocks calcium ions from entering the mast cell, thereby preventing mediator release. Cromolyn sodium inhibits both the immediate…

ANZEMET™ Hoechst Marion Roussel Dolasetron Mesylate Antiemetic Action And Clinical Pharmacology: Dolasetron and its active metabolite, hydrodolasetron (MDL 74156), are selective 5-HT3 receptor antagonists shown not to have activity at other known serotonin receptors and with low affinity for dopamine receptors. The serotonin 5-HT3 receptors are located on the nerve terminals of the vagus in the periphery and centrally in the chemoreceptor trigger zone of the area postrema. It is…

  APO®-ACYCLOVIR Apotex Acyclovir Antiviral Agent Action And Clinical Pharmacology: Acyclovir, a synthetic acyclic purine nucleoside analog, is a substrate with a high degree of specificity for herpes simplex and varicella-zoster specified thymidine kinase. Acyclovir is a poor substrate for host cell-specified thymidine kinase. Herpes simplex and varicella-zoster specified thymidine kinase transform acyclovir to its monophosphate which is then transformed by a number of cellular enzymes to acyclovir diphosphate and…

APO®-CEFACLOR Apotex Cefaclor Antibiotic Action And Clinical Pharmacology: Like other b-lactam antibiotics, cefaclor owes its antibacterial activity to its ability to bind to and inhibit the action of certain bacterial cell wall synthetic enzymes, the penicillin-binding proteins. Cefaclor is well absorbed after oral administration to fed and fasted subjects. Following doses of 250 mg, 500 mg, and 1 g to fasted subjects, average peak serum levels of approximately 7, 13…
