The subject also emphasizes on the chemistry, mechanism of action, metabolism, adverse effects, Structure Activity Relationships (SAR), therapeutic uses and synthesis of important drugs.

Objectives:

Upon completion of the course student shall be able to

  1. Understand the importance of drug design and different techniques of drug design.
  2. Understand the chemistry of drugs with respect to their biological activity.
  3. Know the metabolism, adverse effects and therapeutic value of drugs.
  4. Know the importance of SAR of drugs.
