Abstract
Site-specific colon drug delivery is a practical approach for the treatment of local diseases of the colon with several advantages such as rapid onset of action and reduction of the dosage of the drug as well as minimization of harmful side effects. 5-aminosalicylic acid (5-ASA) is a drug of choice in the treatment of inflammatory bowel disease and colitis. For the efficient delivery of this drug, it is vital to prevent 5-ASA release in the upper part of the gastrointestinal tract and to promote its release in the proximal colon. Different approaches including chemical manipulation of drug molecule for production of prodrugs or modification of drug delivery systems using pH-dependent, time-dependent and/or bacterially biodegradable materials have been tried to optimize 5-ASA delivery to the colon. In the current review, the different strategies utilized in the design and development of an oral colonic delivery dosage form of 5-ASA are presented and discussed.

Design, development, and optimization of polymeric based-colonic drug delivery system of naproxen. ScientificWorldJournal 2013; 2013:654829.

Abstract
The aim of present investigation deals with the development of time-dependent
and pH sensitive press-coated tablets for colon specific drug delivery of naproxen.
The core tablets were prepared by wet granulation method then press coated with
hydroxypropyl cellulose (HPC) or Eudragit RSPO : RLPO mixture
and further coated with Eudragit S-100 by dip immerse method. The in vitro drug
release study was conducted in different dissolution media such as pH 1.2, 6.8, and 7.4
with or without rat caecal content to simulate GIT conditions. Surface morphology and
cross-sectional view of the tablets were visualized by scanning electron microscopy
(SEM). All prepared batches were in compliance with the pharmacopoeial standards.
The tablets which are compression coated with HPC followed by Eudragit S-100 coated
showed highest in vitro drug release of 98.10% in presence of rat
caecal content. The SEM of tablets suggested that the number of pores got increased
in pH 7.4 medium followed by dissolution of coating layer. The tablets coat erosion study
suggested that the lag time depends upon the coating concentrations of polymers.
A time-dependent hydrophilic polymer and pH sensitive polymer based press-coated
tablets of naproxen were promising delivery for colon targeting.
