Abstract A rapid, sensitive, and simple HPLC/MS/MS method was developed and validated for the determination of (5Z,E)-3-[2-(4-chlorophenyl)-2-oxoethyl]-5-(1H-indol-3-ylmethylene)-thiazolidine-2, 4-dione (PG15) in rat plasma using chlortalidone as an internal standard (IS). Analyses were performed using a C18 column and isocratic elution with acetonitrilewater (90 + 10, v/v) containing 10 mM ammonium hydroxide (pH 8.0) as the mobile phase pumped at 0.3 mL/min. Detection was performed by MS with negative ion mode electrospray ionization. Rat plasma samples were prepared by deproteinizing with acetonitrile. Detected fragments were 395.1 > 171.9 for PG15 and 337.3 > 189.9 for the IS. Calibration curves were linear from 10 to 1000 ng/mL, with the determination coefficient >0.99. The intraday and interday precisions were less than 12.2 and 11.3, respectively. The applicability of the HPLC/MS/MS method for pharmacokinetic studies was tested using plasma samples obtained after oral administration of PG15 to rats, and it provided the necessary sensitivity, linearity, precision, accuracy, and specificity.

Metformin Hcl

Background: Food and herbal extracts rich in Quercetin (QRT) are often self-medicated by diabetics and can potentially alter the pharmacokinetics (PK) of Metformin HCl (MET) and Canagliflozin (CNG) leading to food or herb-drug interactions and reduced therapeutic efficacy. However, the impact of these flavonoids on the pharmacokinetic behaviour of MET and CNG is mostly unknown. Methods: A simple one-step protein precipitation method was developed for the determination of MET and CNG from rat plasma. The mobile phase chosen was MeOH 65% and 35% water containing 0.1% formic acid at a flow rate of 1mL/min. Results: The retention time of MET, internal standard (Valsartan) and CNG was 1.83, 6.2 and 8.2 min, respectively. The method was found to be linear in the range of 200 - 8000 ng/mL for CNG and 100 = 4000 ng/ml for MET. Precision and accuracy of the method were below 20% at LLOQ and below 15% for LQC, MQC, and HQC. Conclusion: The method was successfully applied for the determination of PK of MET and CNG by using 100 μL of rat plasma. QRT co-administration affects the PK parameters of MET and CNG. This alteration in PK parameters might be of significant use for clinicians and patients.
