DESIGN AND EVALUATION OF CHRONOTHERAPEUTIC PULSATILE DRUG DELIVERY SYSTEM OF CILNIDIPINE
At present scenario the drug regimen based on circadian rhythm is recently gaining much attention worldwide by researchers. Justification behind it is that, there are various diseases like asthma, hypertension, and arthritis show circadian variation that demand time scheduled drug release for effective drug action. A chronodelivery system, based on biological rhythms, is a state-of the- art technology for drug delivery. The aim of present work is formulate and evaluate a press coated pulsatile release tablets of Cilnidipine using an admixture of hydrophilic polymer i.e. hydroxypropyl methyl cellulose (HPMC) and pH sensitive polymers (ethyl cellulose, eudragit S-100) in order to achieve a predetermined lag time for chronopharmacotherapy of Hypertension. Cilnidipine is the novel calcium antagonist accompanied with L-type and N-type calcium channel blocking function used for the treatment of hypertension. The tablets prepared were evaluated for different properties like bulk density, tapped density, Angle of repose and Carr’s index), hardness, thickness, weight variation, friability, drug content uniformity and in vitro drug release study.

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.
