1- process of drug discovery in its early and clinical trial stages
2- synthesizing key issues around the complexities of novelty,
efficacy and benefit in the approval of new drugs for the market
and post-approval surveillances
3-chemical/molecular structure and any specific aspects of the
structure that may influence activity.
IMPORTANT
Please I don’t want general information.
I want just scientific and academic details.
I do not want any information about what is the drug, for home,
side effects and complication.
About half 900-100 words just about the early clinical trial
