Ronifibrate, a hypolipidemic agent, is an agonist of peroxisome proliferator-activated receptor.

Acipimox (5-methylpyrazinecarboxylic acid 4-oxide) is a new lipolysis inhibitor that has a distant chemical relationship with nicotinic acid (NA). The anti-lipolytic action of acipimox is mediated through suppression of intracellular cyclic AMP levels, with the subsequent decrease in cyclic AMP-dependent protein kinase activity, leading to the reduced association of hormone-sensitive lipase with triacylglycerol substrate in the lipid droplet of adipocytes. Acipimox has been identified as an agonist at G-protein coupled nicotinic acid HM74A and HM74B receptors. Acipimox (Olbetam) is indicated for the treatment as alternative or adjunct treatment to reduce triglyceride levels in patients who have not responded adequately to other treatments such as statin or fibrate treatment for hypertriglyceridaemia (Fredrickson type IV hyperlipoproteinaemia) and hypercholesterolaemia and hypertriglyceridaemia (Fredrickson type IIb hyperlipoproteinaemia).

Meglutol (3-Hydroxy-3-methylglutaric acid, HMGA) is an antilipemic agent which lowers cholesterol, triglycerides, serum beta-lipoproteins and phospholipids, and inhibits the activity of hydroxymethylglutarryl CoA reductases, which is the rate-limiting enzyme in the biosynthesis of cholesterol. 3-Hydroxy-3-methylglutaric acid (HMGA) is a competitive inhibitor of 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCoAR) and strongly reduces cholesterol biosynthesis both in vitro and in vivo. In hamster model HMGA is effective in reducing both bile cholesterol supersaturation and hypercholesterolemia.

Nicofuranose is a niacin derivative used as a hypolipidemic agent. The Nicofuranose administration leads to inhibition of free fatty acid turnover and consequently a marked reduction in triglyceride turnover. Nicofuranose, unlike clofibrate, did not affect the mechanisms responsible for the clearance of plasma triglycerides.

Colesevelam (trade name Welchol) a non-absorbed, polymeric, lipid-lowering agent intended for oral administration. Colesevelam is poly(allylamine hydrochloride) cross-linked with epichlorohydrin and alkylated with 1-bromodecane and (6-bromohexyl)-trimethylammonium bromide. Colesevelam hydrochloride is a hydrophilic, water-insoluble polymer that is not hydrolyzed by digestive enzymes and is not absorbed. Colesevelam is part of a class of drugs known as bile acid sequestrants. Colesevelam hydrochloride, the active pharmaceutical ingredient in Welchol, is a non-absorbed, lipid-lowering polymer that binds bile acids in the intestine, impeding their reabsorption. As the bile acid pool becomes depleted, the hepatic enzyme, cholesterol 7-α-hydroxylase, is upregulated, which increases the conversion of cholesterol to bile acids. This causes an increased demand for cholesterol in the liver cells, resulting in the dual effect of increasing transcription and activity of the cholesterol biosynthetic enzyme, HMG-CoA reductase, and increasing the number of hepatic LDL receptors. These compensatory effects result in increased clearance of LDL-C from the blood, resulting in decreased serum LDL-C levels. Colesevelam is indicated as an adjunct to diet and exercise to reduce elevated low-density lipoprotein cholesterol (LDL-C) in patients with primary hyperlipidemia as monotherapy and to improve glycemic control in adults with type 2 diabetes mellitus, including in combination with a statin. The expanded use of colesevelam in adults with type 2 diabetes mellitus is an example of drug repositioning.

Simvastatin is a HMG-CoA Reductase Inhibitor that is FDA approved for the treatment of hypercholesterolemia and for the reduction in the risk of cardiac heart disease mortality and cardiovascular events. It reduces levels of "bad" cholesterol (low-density lipoprotein, or LDL) and triglycerides in the blood, while increasing levels of "good" cholesterol (high-density lipoprotein, or HDL). Common adverse reactions include abdominal pain, constipation, nausea, headache, upper respiratory infection. Cases of myopathy/rhabdomyolysis have been observed with simvastatin co-administered with lipid-modifying doses ( ≥ 1 g/day niacin) of niacin-containing products. The risk of myopathy, including rhabdomyolysis, is increased by concomitant administration of amiodarone, dronedarone, ranolazine, or calcium channel blockers such as verapamil, diltiazem, or amlodipine.
