Advances in biochemistry authorized for the invention of drug metabolizing enzymes and characterization of the different reactions they catalyzed whilst innovations in molecular genetics authorized for an improved idea of both of those the DNA sequence answerable for the production of these enzymes as well as consequence of genetic variation in that sequence on enzyme action.
Drugs that share elements in their metabolic pathways may also 'contend' for the same binding sites on enzymes, reducing their metabolism's efficiency.
