Abstract

Background: The development of appropriate dosage forms for paediatric antiretroviral therapy is key for improved therapeutic outcomes in children. The focus of this study was to improve solubility, dissolution rate, drug release and maintain high drug permeability.

Methodology: A nanoemulsion was prepared using emulsion inversion point and evaluated. The nanoemulsion had nevirapine (3% w/w). In vitro drug release studies were performed using dialysis membrane. Permeability studies using the Caco-2 cell model were performed for the formulation.

Results: The optimized nevirapine nanoemulsion had a mean droplet size of 36.09±12.27nm, low pdI of 0.598 and zeta potential of -7.87±4.35mV. At pH 2, the nanoemulsion released 76 ± 2 % of nevirapine within 2 h, while at pH 6.4 value representing the small intestine, amount of nevirapine released was 41.6± 4 %. The permeability rate of the nevirapine nanoemulsion was 30.02 x 10-6cm/s and higher than that of propranolol. Efflux ratio was 0.02 indicating low chance of drug efflux occurring.

Conclusion: The results showed that a modified liquid drug release formulations of nevirapine could improve rate of dissolution and maintain high permeability and low drug efflux improving bioavailability of nevirapine in vivo.
