It was revised in 2013 and contains 406 drugs.

Receptor antagonism, partial agonist and inverse agonist, drug synergism, pharmacovigilance, first-pass metabolism, plasma protein binding of drugs, plasma half-life, loading dose, drug treatment of glaucoma, levocetrizine, sodium cromoglycate, lignocaine, etc. are the other topics on which short notes are given in this chapter.
