Drug Discovery is the scientific process of identifying, designing, and developing new medications or therapeutic agents to treat diseases and improve patient outcomes. It involves a multidisciplinary approach that combines biology, chemistry, pharmacology, and computational techniques to discover and optimize potential drug candidates.
Drug delivery refers to approaches, formulations, manufacturing techniques, storage systems, and technologies involved in transporting a pharmaceutical compound to its target site to achieve a desired therapeutic effect. Principles related to drug preparation, route of administration, site-specific targeting, metabolism, and toxicity are used to optimize efficacy and safety, and to improve patient convenience and compliance. Drug delivery is aimed at altering a drug's pharmacokinetics and specificity by formulating it with different excipients, drug carriers, and medical devices.
