Development, Characterization and Evaluation of Tinidazole Nanosuspension for Treatment of Amoebiasis

Pawar RN, Smita N Chavan and Menon MD

Amoebiasis is an infectious disease of gastrointestinal tract caused by the protozoan, Entamoeba histolytica. This disease is widely distributed worldwide and is endemic in most parts of India and other developing countries. The protozoa multiply rapidly in their hosts. Since effective vaccines are as yet unavailable, chemotherapy is the major strategy to treat infected individuals and reduce transmission. Nitroimmidazoles, like Tinidazole (TNZ) form an important class of drugs, which are active against both intestinal and systemic forms of amoebiasis. Most of these drugs have high dose and metallic to bitter taste which result in poor patient compliance. In the present study, nanosuspension was developed by nanoprecipitation method for oral delivery using Tinidazole as model drugs with improved its dissolution rate and hence bioavailability. With improved bioavailability it may be possible to reduce the dose requirement, which would be especially advantageous for paediatric patients. Ex-vivo absorption studies performed using the rat intestinal model showed an enhanced absorption from the nanosuspension as compared to micronized drug.
