dc.description.abstract | The objective of the present work was to investigate the potential for pharmacokinetic drug drug interactions between glimepiride (GMP) and piperazine dithioctate (PDT) in rats to support the development of an orally combined product of the two drugs. An LC-MS/MS bioanalytical method was developed for simultaneous quantification of GMP and thioctic acid (TA) in rat plasma. The accuracy, precision, linearity, selectivity, and recovery were all within an acceptable range. The oral plasma exposure of the GMP solution was more than 14-times greater than that of the GMP suspension at a dose of 0.5 mg/kg, suggesting a dissolution-limited absorption of the GMP suspension. Oral co-administration of PDT (72 mg/kg) with GMP suspension (0.5 mg/kg) reduced the plasma GMP exposure by approximately 80% without a significant change in t(1/2), and t(max) Oral co-administration of PDT with GMP solution had no significant effect on the plasma pharmacokinetics of GMP. PDT lowered the pH (from ca. 7 to 5.6) and the dissolved GMP concentration in the GMP suspension. It was also shown that GMP was more soluble at pH 7 than at 5.7 in an aqueous solution, and the oral plasma exposure of a GMP suspension at pH 7.0 was substantially higher than that of a suspension at pH 5.7. These results suggest that the pH-dependent solubility of GMP was likely responsible for PDT's effect on the oral absorption of GMP. In conclusion, the current work suggests a possibility of drug drug interaction between GMP and PDT upon oral co-administration. | - |
