During the last decade there are new developments in site-specific formulations for targeting drug to the colon. Colon has proved to be a site for the absorption of poorly soluble drugs. Micro carriers as colon drug delivery System has gained importance for the delivery of the drug in the colon because of their increase biocompatibility, controlled release of drug and higher stability. This rev...

The oral route is the preferred route for drug delivery, among oral delivery Intestine and colon drug delivery have been used for molecules aimed at local treatment of colonic diseases such as Colon Cancer, Polyp, Colorectal, Crohn’s Disease, Inflammatory Bowel Disease (IBD), Ulcerative Colitis (UC) etc. and for delivery of molecules susceptible to enzymatic degradation such as peptides. There ...

Green synthesis of mPEG–PLGA and nanoformulation for delivery irinotecan to colon cancer.

Day by day there are new developments in field of colon specific drug delivery system. Colonic drug delivery has gained increased importance not just for the delivery of the drugs for the treatment of local diseases associated with the colon like Crohn’s disease, ulcerative colitis, etc. but also for the systemic delivery of proteins, therapeutic peptides, anti-asthmatic drugs, antihypertensive...

Article reviews the research focus on potential opportunities and challenges available in new area of colon targeted drug delivery system. Colon was considered as “BLACK BOX” as, most of drugs are absorbed from upper part of GIT tract. Targeted drug delivery to the colon would ensure direct treatment at the disease site, lowering of dose and lesser systemic side effects. In addition, the colon ...

Oral administration of different dosage forms is the most commonly used method due to greater flexibility in design of dosage form and high patient acceptance, but the gastrointestinal tract presents several formidable barriers to drug delivery. In oral colonspecific drug delivery system, colon has a large amount of lymphoma tissue (facilitates direct absorption in to the blood), negligible bru...

The colon targeted drug delivery has a number of important implications in the field of pharmacotherapy. Oral colon targeted drug delivery systems have recently gained importance for delivering a variety of therapeutic agents for both local and systemic administration. Targeting of drugs to the colon via oral administration protect the drug from degradation or release in the stomach and small i...

Colon specific drug delivery has achieved utmost importance because the colon is an area that is vulnerable to a number of diseases including ulcerative colitis, crohn’s disease, irritable bowel syndrome and carcinomas. And, preservation of formulation in upper GIT to colon is still important step. Treatment of these diseases with a colon-specific drug delivery system provides an interesting al...

BACKGROUND Colon interposition carries a significant complication rate due to attenuated arterial blood supply, because the interposed colon segment depends on a single vascular pedicle. CASES We report for the first time five vaginal deliveries in two women following the operation, illustrating the dilemmas encountered in choosing the delivery method in these patients. CONCLUSION We sugges...

The purpose of present investigation was to achieve successful delivery especially to colon using microbially triggered, osmotically controlled approach. Prednisolone was chosen model drug for treatment of inflammatory bowel disease (IBD). Prednisolone-β-cyclodextrin complex were prepared and phase solubility study was carried out. Cellulose acetate solution containing chitosan was used to prep...
