Abstract

Objective: Enalapril maleate (EM) is an angiotensin-converting enzyme (ACE) inhibitor. It is generally prescribed for the treatment of hypertension, heart failure and chronic kidney diseases in adults and children. EM 2.5mg, 5mg, 10mg and 20mg tablets and EM injection 1.25 mg/ml are currently available in the market. But a liquid paediatric formulation of this medicine is not currently available. Also, it is a BCS class III drug, having a bioavailability of approximately 60%. The present study proposes a new strategy for improvement of drug bioavailability and taste masking: EM nanoencapsulation within polymeric nanoparticles suspensions prepared with Eudragit RS100 (ERS100) as polymer and Tween 80 as a stabilizer, aiming at obtaining a liquid dosage form suitable for paediatric administration. Methods: Nanoprecipitation method used for the preparation of nanoparticles suspension. The preparations were evaluated for drug content, entrapment efficiency, particle size, zeta potential, polydispersity index, pH, viscosity and in vitro drug release. Based on the entrapment efficiency, viscosity and in vitro drug release the optimized formulation was selected. Optimized formulation evaluated for taste, ex vivo intestinal permeation, differential scanning calorimetry, scanning electron microscopy and release kinetic studies. Results: The optimized nanoparticle formulation F8 having drug to polymer ratio of 1:100 showed satisfactory drug content (95.1%), entrapment efficiency (77.71%), particle size (198.47 nm), pH (6.36), viscosity (2.9 x Pa·s) and 81.2% drug release after 12 hours. The formulation has taste-masking properties and shows 84.6% drug permeation through the goat intestine within 12 hours.

Conclusion: The prepared nanoparticles suspension of Enalapril maleate was found to be an effective liquid pharmaceutical dosage form for paediatric administration with taste-masking properties.
