Molecular pharmacology is that part of pharmacology which specializes in the molecular mechanism of drugs in interaction with biological systems. In other words, it involves the study of the interaction of drugs at the molecular level with the cellular processes, thereby gaining insight into drug action, efficacy, and safety.

Some major areas of molecular pharmacology include drug-receptor interaction, transduction pathways, and drug metabolism. Drugs function through interactions with specific receptors that may reside on the external surface of cells; this generates intracellular events that can occur either as the intended therapeutic response or as adverse side effects. Analyzes of such processes made use of methods involving radiolabeled ligand binding assays, molecular docking, and high-throughput screening.

Signal transduction pathways become central to an understanding of drug control of cellular response. Molecular pharmacology focuses on the ways drugs affect myriad signaling pathways, from GPCRs and kinases to transcription factors. The key rationale behind this understanding is in the design of drugs with actions targeted toward specific pathways and with minimal off-target effects.

Another critical aspect is drug metabolism whereby drugs entering the body undergo metabolism by the enzymes of the liver and other tissues. The knowledge obtained in the metabolic pathways for different drugs will help predict interaction between drugs, potential side effects, and individual variability in drug response.

New drugs also emanate from molecular pharmacology, such as new therapeutic agents and personalized medicine. It will serve to help in designing more specific and safer drugs in consonance with the genetic profile of the individual, by explaining and determining the molecular mechanisms of drug action and resistance.
