Palonosetron is a potent and highly selective serotonin 5-HT(3) receptor antagonist that has been evaluated for the prevention of chemotherapy-induced nausea and vomiting. black triangle Intravenously administered palonosetron has a linear pharmacokinetic profile, with a long terminal elimination half-life ( approximate, equals 40 hours) and moderate (62%) plasma protein binding. In two randomised, double-blind trials in 1132 cancer patients receiving moderately emetogenic chemotherapy, intravenous palonosetron 0.25 mg was more effective than intravenous ondansetron 32 mg in producing a complete response (no emesis, no use of rescue medication) during acute (0-24 hours) or delayed (24-120 hours) phases, and similar to intravenous dolasetron 100 mg in acute, but more effective in delayed phase. ⋯ Intravenous palonosetron was generally well tolerated in clinical trials, with few adverse events being treatment related. Palonosetron had no significant effect on the corrected QT interval or laboratory parameters.

Randomized Controlled Trial Multicenter Study Clinical Trial
Prevention of coronary and stroke events with atorvastatin in hypertensive patients who have average or lower-than-average cholesterol concentrations, in the Anglo-Scandinavian Cardiac Outcomes Trial--Lipid Lowering Arm (ASCOT-LLA): a multicentre randomised controlled trial.
The lowering of cholesterol concentrations in individuals at high risk of cardiovascular disease improves outcome. No study, however, has assessed benefits of cholesterol lowering in the primary prevention of coronary heart disease (CHD) in hypertensive patients who are not conventionally deemed dyslipidaemic. ⋯ The reductions in major cardiovascular events with atorvastatin are large, given the short follow-up time. These findings may have implications for future lipid-lowering guidelines.
