The aim of the study was to develop novel drug design of etoricoxib microbeads for sustained drug delivery by oral route which reduces the dosing frequency. Etoricoxib is a NSAIDs commonly used by patients so to reduce the dosing frequency of drug administration the etoricoxib loaded microbeads were prepared with sodium alginate and calcium chloride in different ratios by inotropic gelation technique and characterized by FTIR, drug entrapment efficiency, particle size, swelling Index and release profile. The microbeads show that 3.86±0.28% of surface entrapment, drug content87±0.35%, swelling Index was found to be 80.76 and 88.72±0.15drug entrapment of F4 formulation depending on polymer/drug ratio. The IR spectrum shows stable character of etoricoxib in the microbeads and revealed an absence of drug polymer interaction. The prepared microbeads were spherical in shape and had a size range of 125±0.02to 165±0.18µm, the release of the drug was found to be 64.092±0.24 in F4 formulation among all formulation in 240 minutes which shows that the drug released by sustained effect and shows kinetic release mechanism the formulation F1 shows fickian diffusion and F2, F3 and F4 shows the super-case Ⅱ transport which depends upon the loss of polymeric chain and the release of drug takes place.

Peer Review History:

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 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.
