Tương tác
Anion-exchange resins (e.g. cholestyramine) inhibit bezafibrate absorption, take at least 2 hr apart. May increase serum concentration of anticoagulants. Increased risk of renal impairment when used w/ immunosuppressants. May potentiate the therapeutic effect of sulfonylureas and insulin. Estrogens may increase lipid levels, dosing should be individualised in patients taking oestrogen-containing contraceptives.
Potentially Fatal: Potential hepatotoxic effect when used w/ perhexiline maleate or MAOIs. Increased risk of myopathy in predisposed patients who are taking HMG-CoA reductase inhibitors. |

Tác dụng
Description:
Mechanism of Action: Bezafibrate, a fibric acid derivative, reduces VLDL and LDL while increasing HDL levels. It increases the activity of triglyceride lipases involved in the catabolism of triglyceride-rich lipoproteins and inhibits hepatic acetyl co-enzyme A carboxylase synthesis. Pharmacokinetics: Absorption: Rapid and almost completely absorbed in the GI tract. Time to peak serum concentration: 1-2 hr (conventional); 3-4 hr (modified-release). Distribution: Volume of distribution: Approx 17 L. Plasma protein binding: 94-96%. Excretion: Via urine (95%, 50% as unchanged drug and 20% as glucuronides); faeces (3%). Elimination half-life: 1-2 hr. |
