Gemfibrozil ve Pioglitazon ve glimepirid etkileşimi

(C) CYP2C8 Substrates Gemfibrozil is a strong inhibitor of CYP2C8 and may increase exposure of drugs mainly metabolized by CYP2C8 (e.g., dabrafenib, enzalutamide, loperamide, montelukast, paclitaxel, pioglitazone, rosiglitazone).

Strong CYP2C8 inhibitors (e.g., gemfibrozil) increase pioglitazone concentrations.

Strong CYP2C8 Inhibitors Pioglitazone An inhibitor of CYP2C8 (e.g., gemfibrozil) significantly increases the exposure (area under the serum concentration-time curve or AUC) and half-life (t ½ ) of pioglitazone.

Therefore, the maximum recommended dose of pioglitazone is 15 mg daily if used in combination with gemfibrozil or other strong CYP2C8 inhibitors.

Since the minimum dose of pioglitazone in pioglitazone and glimepiride tablets exceeds 15 mg, patients taking concomitant strong CYP2C8 inhibitors should switch to individual components of pioglitazone and glimepiride tablets, unless the prescribing health care provider determines that the benefit of pioglitazone and glimepiride tablets clearly outweighs the…
