| Popis: | Procedures were developed for the simultaneous determination of pharmaceuticals in two-component commercial formulations by first-order derivative UV spectrophotometry. Phenylephrine hydro chloride and carbinoxamine maleate in capsules and diphenhydramine hydrochloride and naphazolixehydro hydrocloride in nasal gelly were succesfully assayed. A simple sensitive method in the usual range for the binary preparations has been developed. Average recoveries of the four compounds in the formulations under study were 100.04 ± 1.28% 101.50 ± 2.27 %, 101.59 % 1.24 % and 100.49 ± 2.59 %. |
