Abstract

BUONTEMPO, F.; MORETTON, M. A.; QUIROGA, E.  and  CHIAPPETTA, D. A.. Extemporaneous clobazam suspensions for paediatric use prepared from commercially available tablets and pure drug. Farm Hosp. [online]. 2013, vol.37, n.2, pp.103-110. ISSN 2171-8695.  https://dx.doi.org/10.7399/FH.2013.37.2.117.

Objective: Two clobazam aqueous suspensions for paediatric oral usage (5 mg/ml) were investigated to determinate its physicochemical stability under different storage conditions. Method: Formulations were stored at 4 and 25 ^oC and the clobazam content was determined by High Performance Liquid Chromatography. Each sample was analyzed by triplicate at different time points (0, 7, 14, 28 and 56 days). Results: Liquid suspensions were successfully formulated from pure drug and commercially available tablets. In both cases, samples showed suitable physical stability. Clobazam was chemically stable in aqueous suspension during the 56 days of the study at the two storage temperatures. Conclusions: All the tried oral liquid formulations can be conserved at 4 and 25 ^oC at least 56-day period.
