Formulation and characterization of metformin hydrochloride orodispersible tablets with super disintegrants

Abstract

Metformin hydrochloride's fast onset of action is very desirable, making it a prime candidate for the preparation of orodispersible tablets in the present study. This medication is prescribed for the management of type 2 diabetes, which does not respond to insulin. The tablets were made using direct compression and a mixture of the super disintegrants sodium starch glycolate (SSG) and croscarmellose sodium (CCS). Mannitol is a sugar-based excipient that serves as a binding agent, dissolves well in water, and provides a pleasant mouth feel. The blend's pre-compression results show that the medication excipients work well together and have desirable compression characteristics. Eight distinct formulations with varying amounts of SSG, CCS, and Mannitol were made. The properties of the tablets' drug release were measured, including their in vitro disintegration time, water absorption ratio, mechanical stability, wetting time, and so on. When using a greater concentration of SSG, CCS, and Mannitol, formulations F4 and F8 showed shorter in vitro disintegration times of 10.2 and 7.8 ​s, respectively, and formulation F8 showed 99.65% in vitro drug release at the end of 30 ​min. The orodispersible tablet performance can be enhanced through direct compression using the super disintegrants inclusion methodology.
