Pravastatin, sold under the brand name Pravachol among others, is a statin medication, used for preventing cardiovascular disease in those at high risk and treating abnormal lipids. [5] It is suggested to be used together with diet changes, exercise, and weight loss. [ 5 ]
WOSCOPS was a multicenter, randomized, double-blind, placebo-controlled trial conducted in Scotland. The study enrolled 6,595 men aged 45 to 64 years (average 55 years) with elevated total cholesterol levels (average 272 mg/dl) and LDL cholesterol levels (average 192 mg/dL) and no previous history of myocardial infarction.
Dosage typically includes information on the number of doses, intervals between administrations, and the overall treatment period. [3] For example, a dosage might be described as "200 mg twice daily for two weeks," where 200 mg represents the individual dose, twice daily indicates the frequency, and two weeks specifies the duration of treatment.
Cardiovascular agents generally have narrow therapeutic indices, implying that small differences in dose or blood concentration may give rise to adverse drug reactions. [45] Serious acute toxicity may result from accidental, intentional or iatrogenic overdose. [46] Therefore, patients need to be aware of any unusual and serious side effects.
Data collection also did not note the dosage of statin medications, medication adherence, or changes in HDL cholesterol levels. Furthermore, the researchers did not stratify atherosclerotic ...
On average, statins can lower LDL cholesterol by 1.8 mmol/L (70 mg/dL), which translates into an estimated 60% decrease in the number of cardiac events (heart attack, sudden cardiac death) and a 17% reduced risk of stroke after long-term treatment. [36] A greater benefit is observed with high-intensity statin therapy. [37]
Pravastatin belongs to the group called statins. [2] It reduces total blood cholesterol by blocking the action of 3-hydroxy-3-methyl-glutaryl-coenzyme-A (HMG-CoA) reductase, an enzyme in the liver involved in the production of cholesterol. [ 2 ]
Drug titration is the process of adjusting the dose of a medication for the maximum benefit without adverse effects. [1] When a drug has a narrow therapeutic index, titration is especially important, because the range between the dose at which a drug is effective and the dose at which side effects occur is small.
