Microemulsions as the Potential Delivery System for Nimodipine

An important area of interest in pharmaceutical technology is the issue of poorly soluble drugs and their formulation into drug dosage forms that ensure optimal bioavailability. One of the options to solve solubility is the development of nanodispersion systems. This work is focused on the preparation of microemulsion systems suitable for poorly soluble drugs, for example, nimodipine. The composition and structure of microemulsion enable solubilization of different drugs and make it a universal drug carrier. Microemulsions increased the solubility of the model drug 20-fold compared to solubility in water. The use of mucoadhesive polymers – hydroxyethyl cellulose and xanthan gum – improved the in vitro release significantly. The highest amount of nimodipine was released from the microemulsion gel system with hydroxyethyl cellulose (1% w/w) and this depended on the diffusion of dissolved molecules.
