The advancement in medicines and drugs is not merely the discoveries in medicine laboratories. The clinical trials are the essential parts of research process, which can ensure that the newly invented drugs can function properly in our body. The process of clinical trial incorporate many stages and patients willing to help in finding new treatments can test any new drug or medicine, along with getting compensation with time. In fact, clinical trials have to pass through different steps before obtaining approval from FDA.

Phases of Clinical Trials to Launch New Drug

The Clinical Trials in Southern California revealed that the clinical trial of any new drug is consisting of 4 different phases, starting from initial stage to obtaining of approval from FDA. Firstly, the newly invented drug has to pass through phase 1, which is even referred as initial test. In this phase, researchers administered the new drug to only few volunteers and have close monitoring of these volunteers. Thus, in this manner, researchers can ensure themselves that human body is giving proper response to the drug. After this, new drug entered in to the second phase. In this phase, researchers test the drug by having large test group. In the third phase, researchers compared the properties of new drug against the properties of already existing medications. In the fourth phase or last phase, new drug obtained the approval from FDA.
