Summary
A new high-performance liquid chromatography (HPLC) method was developed and validated for accurately assaying 200-mg troglitazone tablets. This validated method ensures reliable quality control for troglitazone drug products.
Area of Science:
- Analytical Chemistry
- Pharmaceutical Analysis
Background:
- Troglitazone is an important pharmaceutical agent.
- Accurate quantification of active pharmaceutical ingredients is crucial for drug safety and efficacy.
Purpose of the Study:
- To develop and validate a robust isocratic, reversed-phase, high-performance liquid chromatographic (HPLC) method.
- To accurately quantify troglitazone in 200-mg tablet formulations.
Main Methods:
- Utilized a YMC ODS-A column with a specific mobile phase composition (aqueous NaH2PO4, acetonitrile, methanol).
- Employed isocratic elution at a flow rate of 1.0 ml/min with ultraviolet (UV) detection at 225 nm.
- Analyzed samples using peak area responses at ambient column temperature.
Main Results:
- Successfully developed and validated an isocratic, reversed-phase HPLC method.
- The method is suitable for the assay of 200-mg troglitazone tablets.
- Demonstrated reliable quantification using peak area responses.
Conclusions:
- The developed HPLC method provides accurate and reliable quantification of troglitazone in tablet dosage forms.
- This method is suitable for routine quality control and pharmaceutical analysis.
- The validation confirms the method's suitability for its intended purpose.
