Colon delivery systems for oral administration have grown in popularity since the 1990s, primarily because of the increasing incidence of inflammatory bowel disease (IBD) that has broadly been demonstrated to benefit from topical pharma- cological treatment.

Abstract: Background: Colorectal carcinoma is the fourth most common internal malignancy; it is second only to carcinoma of the lung as a cause of carcinoma death. 6-Mercaptopurine (6-MP) is a drug of choice in the treatment of Crohn's disease, ulcerative colitis and colorectal cancer. The drug shows irritation on gastric exposure. It has poor bioavailability with half life less than 2 h. Targeted delivery of 6-MP will provide an effective and safe therapy for colon diseases. Objective:...

As a novel drug delivery approach, piroxicam an anti rheumatoid drug is loaded in microspheres prepared by chitosan as a polymer and coated with eudragit S-100 to prepare colon speci c microspheres which increases the bioavailability of the drug to the targeted area and in a controlled manner and reduces GI related side effects. In the present study chitosan microspheres were prepared using emulsion crosslinking technique, glutaraldehyde as a crosslinker and microencapsulation using phase...

Abstract Lansoprazole degrades rapidly in an aqueous solution at low pH values. Degradation rate increases at pH values below 4 .The aim of this study was development of enteric coated pellets containing Lansoprazole by an extrusion/ spheronization technique. Eight different formulations based on lactose and six different formulations based on mannitol, consisting of different portions of other excipients including sucrose, hydroxy propyl methyl cellulose, magnesium carbonate, and sodium lauryl...

This research has investigated over different parameters and combined the additional anti-cancerous properties of high ester pectin based formulation, which exhibit almost negligible degradation by colonic bacteria. In present investigation compression coated tablets were prepared using high ester pectin derived from Mangifera indica fruit peel for colon specific delivery of 5-Fluorouracil. Pectin was extracted from dried fruit peel powder of Mangifera indica using water acidi ed with 0.2 M...

ABSTRACT: Tablets are widely used and most preferred dosage form because of its ease of manufacture and administration, lower cost, good aesthetic appearance. Now a days new trends are going to develop in formulation of conventional tablet in to modified tablet dosage forms like floating, sustained release matrix, coated tablets, controlled release, fast release etc. This review provides the detail information of compression coated tablets including its classes, polymers commonly used in...

Compaction of multiple-unit pellet system (MUPS) tablets has been extensively studied in the past few decades but with marginal success. This study aims to investigate the formulation and process strategies for minimizing pellet coat damage caused by compaction and elucidate the mechanism of damage sustained during the preparation of MUPS tablets in a rotary tablet press.

Urea cycle disorders are a group of inherited orphan diseases leading to hyperammonemia. Current therapeutic strategy includes high doses of sodium benzoate leading to three or four oral intakes per day. As this drug is currently available in capsules or in solution, children are either unable to swallow the capsule or reluctant to take the drug due to its strong bitter taste. More
