And the drug is safe for human ingestion and stands a fair prospect of treating the illness it's meant to tackle.
If a medication makes it through the initial trial, it is going to proceed to stage two. In stage two, the principal intention is to check the potency of the medication in treating its planned symptom or disease.

After a medication has passed a phase three trial, it's prepared to be accepted by the FDA. However, there's an additional phase of testing: stage four. This really is a post-market stage, in which the provider keeps tabs on potential problems that slipped through the cracks in the past trials. For example, extremely low-frequency negative effects just appear as soon as the medication is utilized by thousands and thousands of individuals.
