Stability of extemporaneous enalapril maleate suspensions for pediatric use prepared from commercially available tablets.
In this paper, the stability of enalapril maleate in oral formulations prepared from commercially available tablets was investigated. Extemporaneously compounded, 0.1 mg/mL and 1.0 mg/mL, oral suspensions of enalapril maleate in sugar-containing and sugar-free vehicles were stored in the absence of light at 4 degrees and 25 degrees C for 30 days. Enalapril maleate stability was quantified after...
متن کاملComparison of two commercially available isolation systems for Chlamydia trachomatis.

متن کاملExtemporaneous Furosemide Suspensions for Pediatrics Use Prepared from Commercially Available Tablets
Objective: Three furosemide aqueous suspensions for paediatric oral usage (2 mg/ml) were investigated to determinate its physicochemical stability under different storage conditions. Method: Formulations using sugar syrup and sugar-free vehicles were stored at 4 and 25 o C and the furosemide content was determined by spectrophotometer. Each sample was analyzed in triplicate at different time po...
