Dược Lực Học :
FM VP4 is thought to bind competitively with cholesterol to MDR1 resulting in a synergistic decrease in cholesterol accumlation. Others have suggested that FM VP4 may act by inhibiting a transporter that mediates intestinal absorption of cholesterol.
Cơ Chế Tác Dụng :
FM-VP4, is a novel hydrophilic phytostanol analogue representing a new class in cholesterol-lowering drugs called cholesterol absorption inhibitors. FM-VP4 has been shown to inhibit cholesterol absorption and to lower plasma LDL-cholesterol and total cholesterol in a broad range of animal species. Additional experiments suggest that FM-VP4 can reduce plasma LDL cholesterol levels and triglyceride levels, reduce weight gain and exert a anti-atherosclerosis effect

One study indicates that FM-VP4 inhibits cholesterol accumulation within IEC-6 cells and is most effective at equimolar concentrations with cholesterol, further suggesting that the action of FM-VP4 is likely at the cell surface and not elicited intracellularly.
Độc Tính :
Clinical trials have indicated that the drug is well-tolerated.
Chỉ Định :
Investigated for use/treatment in hyperlipidemia and cancer/tumors (unspecified).
Monotherapy is recommended for people with marginally high LDL-cholesterol or who cannot be prescribed statins due to drug interactions and safety concerns. Combination Therapy is recommended if statin therapy alone is either insufficient to achieve the guidelines set by the NCEP or there is concern over side effects as Statin doses can be lowered in combination treatment without losing efficacy.
