The study aims to investigate the impact of intergranular superdisintegrant on the properties of drotaverine hydrochloride fast-dissolving granules and orodispersible tablets. Orodispersible tablets were obtained by compressing the granules and excipient mixture. Different concentrations of superdisintegrant excipients were used to develop the tablets, which met the quality requirements in terms of friability, crushing strength, and disintegration time. The release of drotaverine from the tablets showed satisfactory results within the specified time.
The main objective of this study consists in establishing the influence of the intergranular superdisintegrant on the specific properties of drotaverine hydrochloride fast-dissolving granules (DROT-FDGs) and orodispersible tablets (DROT-ODTs). The orodispersible tablets were obtained by the compression of the FDGs and excipient mixture with an eccentric tableting machine. To develop DROT-ODTs, two types of superdisintegrant excipients in different concentrations (water-soluble soy polysaccharides (SSP) (1%, 5%) and water-insoluble soy polysaccharides-Emcosoy (R) STS IP (EMCS) (1%, 3%, 5%)) were used, resulting in five formulations (D1-D5). The DROT-FDGs and the DROT-ODTs were subjected to pharmacotechnical and analytical evaluation. All the orodispersible tablets obtained respect the quality requirements in terms of friability (less than 1%), crushing strength (ranging between 52 N for D2 and 125.5 N for D3), and disintegration time (<180 s). The in vitro release of drotaverine from ODTs showed that all formulations presented amounts of active substance released greater than 85% at 10 min. The main objective, developing 30 mg DROT-ODTs for children aged between 6 and 12 years by incorporating the API in FDGs, was successfully achieved.
