Ezetimibe - A New Class of Lipid-Lowering Drugs
by Pharma - 5342 reads, based on 8 votes
Introduction Statins are among the best-studied drugs for the primary and secondary prevention of atherosclerosis, and particularly of coronary heart disease. Their tolerability is generally very good. Their lipid-lowering effect is species and dose dependent, and the maximum lowering of the LDL cholesterol level can be up to 55%.

This rule also applies to the side effects, which most often involve the liver enzymes and the musculature. Raised liver values are found in 0.5–2.0% of the patients, and the incidence of myopathy is 0.1–1.0%... More

Similar to morphine with respect to analgesic potency and onset and duration of action. Less risk of abuse due to the mixed agonist-antagonist properties of the drug.
