All medicines either in the form of pills or liquid interact with our body by forming a bond with target specific receptors. For instance if a pain killer is taken then it shall form bond with receptors produced by pain and inflammation
So medicines are basically chemical which interact with biomolecules such as enzymes, nucleic acid, hormones, ions etc. by forming ionic bond, hydrogen bond, van der wall force etc. in the active site of enzyme.
