FORMULATION AND IN-VITRO EVALUATION OF FLOATING MICROBALLOONS OF STAVUDINE

Abstract

Objectives: Objective of present study involves preparation and evaluation of floating microballoons of Stavudine. It is a potent antiviral agent, used for treatment of human immunodeficiency virus (HIV) infection. In present study Stavudine is used as a model drug, to increase its residence time in the stomach without contact with the mucosa. Methods: Eight floating microballoons formulations of Stavudine were prepared by using different polymers i.e. Eudragit S100, EC and PVP K30, in different ratio by emulsion solvent diffusion method. The microballoons were prepared by the emulsion solvent diffusion technique using different ratio of polymers (Eudragit S100, Ethyl cellulose and PVP K 30) as carriers. Results: The mean particle diameter of the microballoons was between 230.23-238.33µm.The yield of microballoons was up to 68.32-80.22%. The cumulative percent drug release after 24 hrs of the Stavudine microballoons was in the range of 53.62 to 87.45%. The mean percentage buoyancy of the microballoons was between 69.23-82.53%. The cumulative percent drug release after 24 hrs of the Stavudine microballoons was 53.62 to 87.45%. Conclusion: Stavudine floating microballoons formulations of batch MB4 was concluded as the optimum formulations among the all 8 formulations based on different parameters.Study concludes that stavudine can be delivered through floating microballoons dosage form in an effective way. Peer Review History: Article received on- 29 September; Revised on- 20 October; Accepted on- 5 November , Available online 15 November 2016 Academic Editor: Ahmad Najib, Universitas Muslim Indonesia, Indonesia, ahmad.najib@umi.ac.id UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
