Biomedical research is essential for enhancing human health and well being.
Development of a therapeutic drug is a complex process. At times it involves Research over 2 to 3 decades and may cost crores of rupees. It is mandatory that any drug before being marketed is evaluated for its toxicology and efficacy in controlled trials in human sunjects. The type of experimental protocol or procedure that a human volunteer or a patient may be exposed to will vary with the complexity of the medical intervention and is often associated with a certain amount of risk. Similar considerations also apply to studies on subjects designed to evaluate newly developed diagnostic agents, medical devices and vaccines.
