Background: Olanzapine (OLZ) is one of most recommended drugs for the treatment of schizophrenia while metformin (MET) is the most commonly used hypoglycemic agent. Aim: Development and validation of two green, sensitive and accurate chromatographic methods for the simultaneous determination of OLZ along with the co-prescribed, MET. Materials & methods: TLC-densitometric method with a developing system consisting of methylene chloride:methanol:ethyl acetate:triethylamine (4:4:5:0.1, by volume) and a reversed-phase (RP)-HPLC method where the chromatographic separation was performed using ethanol:water mixture (50: 50, v/v) as a mobile phase. Results: TLC-densitometric method had linearity over concentration ranges of 160–4000 ng/band for OLZ and 150–4500 ng/band for MET, while RP-HPLC method was linear and validated over concentration range of 300–20000 ng/ml for OLZ and MET. Conclusion: Pharmacokinetic study was successfully performed and suggested the possibility of co-administration of MET with OLZ and their further formulation in one pharmaceutical preparation to enhance patient’s compliance.

Development And Validation

A sensitive and accurate reversed– phase high performance liquid chromatography (RP-HPLC) method with UV absorbance detection at 289 nm was developed and validated for the determination and quantification of besifloxacin (BSF) in rat plasma. Ofloxacin was used as an internal standard (IS). The sample was prepared by liquid extraction of BSF from plasma, using methanol and acetonitrile (70:30). The chromatographic separation was achieved with octadecylsilane (ODS-3), Hypersil® C18 column (250 mm×6mm×5μm). The chromatographic runtime was less than 5 minutes where the retention time of internal standard and the drug was 2.15 min and 3.30 min respectively. A standard curve with a regression coefficient (r2) 0.999 was obtained in the range of 0.025-20 μg/mL. The method was validated with respect to linearity, range, precision, accuracy and robustness according to ICH guidelines. The method was found to be accurate and robust with a runtime of less than 5 minutes. Hence, the present method was rapid and economical to use for clinical studies as well as to analyze the drug in different plasma samples.
