مستخلص: | The determination of nimodipine in the presence of its degradation products, formed through photolysis, acidic and alkaline hydrolysis, and the drug degradation kinetics under these conditions, was investigated through a validated liquid chromatography method. Separation was achieved using a Phenomenex Luna C18 column (250 × 4.6 mm i.d., 5 µm) with a mobile phase consisting of acetonitrile-methanol-water (55:11:34, v/v/v), at 0.5 mL/min and with ultraviolet detection at 235 nm. The method was considered to be specific, accurate, precise, robust and linear over the concentration range of 5.0 to 35.0 µg/mL. The drug followed a first-order reaction for both hydrolysis and photolysis in methanol, and zero-order for photolysis in acetonitrile and water. The calculated activation energies were 10.899 and 23.442 kcal/mol for alkaline and acidic hydrolysis, respectively. No degradation was observed under thermal and oxidative stress conditions. |
