Colon-Targeted Oral Drug Delivery Systems: Design Trends and Approaches

Novel Approaches in Colon Targeted Drug Delivery Systems

Although oral delivery has become a widely accepted route of administration of therapeutic drugs, the gastrointestinal tract presents several formidable barriers to drug delivery. Colonic drug delivery has gained valued attention not just for the targeted delivery and effective therapy of local diseases associated with the colon but also for its potential for the delivery of proteins and therap...

Colon Targeted Drug Delivery Using Different Approaches

Although oral delivery has a become a widely accepted route of administration of therapeutic drugs, the gastrointestinal tract presents several formidable barrier to drug delivery. The delivery of drugs to the colon has a number of therapeutic implications in the field of drug delivery. In the recent times, the colon specific drug delivery system is also gaining importance not only for local dr...

A Promising Approaches of Colon Targeted Drug Delivery System

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...

Formulation and Evaluation of Colon Targeted Oral Drug Delivery Systems for Metronidazole in Treatment of Amoebiasis

The aim of study is to develop colon targeted system for metronidazole using guar gum and xanthan gum. Matrix formulations containing various proportions of guar gum and xanthan gum were prepared by wet granulation technique. Later on, multilayer tablets were prepared by using 50 mg and 100 mg of guar gum as release controlling layer on either side of (M5) matrix tablets of metronidazole. The i...
