3. Dosage Forms and Strengths
Linearity was assessed using a concentration range of 0.01 - 60.00 µg/mL, achieving a correlation coefficient of 0.9999. The method yielded a limit of detection (LOD) of 3.82 ng/mL and a limit of quantification (LOQ) of 11.57 ng/mL. Under forced degradation, 95.99% of sildenafil remained after treatment with acidic and basic hydrolysis, indicating good stability. The accuracy tests showed an overall recovery of 100.18% across spiked concentrations, demonstrating method reliability.
