Delipid – Gemfibrozil is used as a hypolipidemic agent in conjunction with dietary modification. It is recommended in the treatment of type IIa, type IIb, type III, type IV and type V hyperlipoproteinemia.
Delipid – Gemfibrozil is an anti-lipemic agent. Gemfibrozil decreases serum triglycerides in healthy individuals and patients with hyper-triglyceridemia. It decreases very low-density lipoprotein (VLDL)- triglyceride concentration and to a lesser extent, LDL triglyceride concentration. HDL-triglyceride is usually decreased slightly. Gemfibrozil usually increases the HDL-cholesterol fraction in healthy individuals and patients with hyperlipoproteinemia, an action that may be beneficial in slowing the progression of atherosclerosis and in reducing the risk of coronary heart disease.
Gemfibrozil also inhibits synthesis of VLDL carrier apolipoprotein B, leading to a decrease in VLDL production. How gemfibrozil raises HDL concentration is not known. Gemfibrozil inhibits lipolysis of fat in adipose tissue and decreases the hepatic uptake of plasma free fatty acids, thereby reducing hepatic triglyceride production.
Dosage & Administration
The usual dose by mouth is 1.2 gm daily in 2 divided doses given 30 minutes before morning and evening meal. The dosage range may vary between 0.9-1.5 gm daily or as directed by the physician.
Concomitant anticoagulant dosage may need to be reduced and frequent determinations of prothrombin carried out to confirm that the desired prothrombin level has been re-established. There have been reports of severe myositis with marked elevation of creatinine kinase and myoglobinuria when Delipid – Gemfibrozil and lovastatin were used concomitantly. In most subjects who have had an unsatisfactory lipid response to either drug alone, the possible benefit of combined therapy with lovastatin and Gemfibrozil does not outweigh the risks of severe myopathy, rhabdomyolysis and acute renal failure.
Hypersensitivity. Severe hepatic or renal dysfunction; gall stones; neonates, children, pregnancy, lactation.
The most frequent adverse effect involves the G. I. Tract. Abdominal pain and epigastric pain or dyspepsia is common adverse G. I. effects. Other adverse reaction includes pruritus, rash, headache, dizziness, blurred vision, painful extremities and rarely myalgia.
Pregnancy & Lactation
Safe use in human pregnancy has not been established. It is not known whether gemfibrozil is secreted in human milk. Like most drugs, gemfibrozil should normally be avoided during pregnancy and lactation.
Causes of secondary hyperlipidaemia such as hypothyroidism and diabetes must be treated before initiating therapy. Renal impairment; blood disorders. Periodic monitoring of the serum lipids should be done; if no adequate response after 3 mth, treatment should be withdrawn. May increase risk of cholelithiasis.
It should be stored in a dry place at room temperature.
