Stability-Indicating HPLC Method for Simultaneous Determination of Sulfadimethoxine and Ormetoprim in an Oral Solution
A stability-indicating HPLC method was developed and validated for the simultaneous determination of sulfadimethoxine (SDM) and ormetoprim (OMP) in an oral solution. Chromatographic separation was achieved on a C18 column using 0.05% (v/v) phosphoric acid in water and methanol as the mobile phase under gradient elution...
