Lipid Lowering Drugs (New)
Summary
Fish oil contains omega-3 fatty acids and is used as a lipid lowering drug to treat hyperlipidemia. Fish oil works by decreasing free fatty acid delivery to the liver, which decreases triglyceride synthesis in the body.
On laboratory testing, patients may experience a fall in triglyceride levels when fish oil is taken at high doses. Patients may also experience a slight rise in HDL levels and a slight rise in LDL levels. Side effects of fish oil include nausea and other symptoms of GI upset. Patients may also complain of fish oil having a fish-like taste.
