Abstract

Objective: The objective of the present study was to formulate solid dispersions (SD) of Ezetimibe to improve the solubility and dissolution rate to facilitate faster onset of action. Ezetimibe is poorly water soluble BCS class II drug and used as a hypolipidemic agent. It has poor bioavailability (35-65%) due to its low dissolution profile in gastro intestinal tract.


Methods: In the present study, eight solid dispersion formulations of Ezetimibe with polymers PEG-4000 and PEG-6000 were prepared by solvent evaporation and fusion methods.  Solid dispersion formulations were characterized by content uniformity, flow properties and in vitro dissolution studies.


Results: The solubility of Ezetimibe powder in distilled water at 37±0.5°C was 2.37±0.14 µg/ml, whereas solubility of the solid dispersion formulations was in the range of 322.43-37.48 µg/ml. Percent yield of eight solid dispersion formulations of Ezetimibe lies in range of 98.20 to 99.42% w/w. 


Conclusion: Present study concluded that the Ezetimibe solid dispersion formulations are a suitable approach to improve the solubility and dissolution rate of ezetimibe than pure form of drug.

Peer Review History:


Received 2 February 2017;   Revised 28 February; Accepted 3 March, Available online 15 March 2017


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.
