Acute use (1–3 days) yields a potency about 1.5× stronger than that of morphine and chronic use (7 days+) yields a potency about 2.5 to 5× that of morphine. Similarly, the effect of tramadol increases after consecutive dosing due to the accumulation of its active metabolite and an increase of the oral bioavailability in chronic use.
Ezetimibe/atorvastatin (trade names Liptruzet, Atozet) is a cholesterol lowering combination drug.In the United States, it was approved in May 2013, by the Food and Drug Administration for the treatment of elevated low-density lipoprotein (LDL) in patients with primary or mixed hyperlipidemia as adjunctive therapy to diet. [1]
All statins appear effective regardless of potency or degree of cholesterol reduction. [ 25 ] [ 45 ] [ 46 ] Simvastatin and pravastatin appear to have a reduced incidence of side-effects. [ 5 ] [ 47 ] [ 48 ]
[22] [23] Another consequence of taking statins is the risk of developing new-onset diabetes, which is more prominent in individuals with high TG levels and body mass index (BMI). [19] However, the risk is far outweighed by the benefits from statin therapy for the reduction in cardiovascular outcomes. [20]
The effects of rosuvastatin on low-density lipoprotein (LDL) cholesterol are dose-related. Higher doses were more efficacious in improving the lipid profile of patients with hypercholesterolemia than milligram-equivalent doses of atorvastatin and milligram-equivalent or higher doses of simvastatin and pravastatin.
Statin-induced rhabdomyolysis is rare, occurring in less than 0.1% of people who take statins. [64] [65] [66] Statin induced rhabdomyolysis, as with other statin associated muscle symptoms, occurs most commonly in the first year of treatment but can occur at any time during treatment. [64]
The pharmacological results from cerivastatin show that it is the most active HMG-CoA-reductase inhibitor among reported statins. Due to its high enzyme affinity, it would seem to offer ultra-low dose therapy in the microgram range. However, due to its relatively severe adverse effects in comparison to other statins, its market use was ...
In pharmacology, potency or biological potency [1] is a measure of a drug's biological activity expressed in terms of the dose required to produce a pharmacological effect of given intensity. [2]
