Drug discovery is a process of searching new therapeutically useful entities. The process of bringing a new drug to the market consists of four main stages-drug discovery, preclinical testing, clinical trials and FDA review. Drug discovery involves the searching of a new compound by lead search, combinatorial chemistry and HTS. After getting a new compound, preclinical testing and preformulation are done. INDA is required for continuing, the process in phases of clinical trials. Final step is submission of NDA to FDA, and a drug comes in the market after approval of FDA. This process continues here also with post-market surveillance, long term effect of a drug is studied. Drug discotery is a challenging process requiring a huge amount of money, time and man power.
