**3.4 Biochemical effects**

The biochemical effects, also an outcome of the drug-receptor interaction that is referred as therapeutic processing of drugs that aids the modification of the drug's conformation according to the environment of the receptor. Since the function of the molecule is associated with the structure of molecule, if the structure of the molecule is modified, then mechanism of receptor might be modified or inhibited by the instance of biochemical interaction which as a result exposes biochemical effects. The administration of oral drug creates a long lasting intense effect whereas the injections possesses and intense effects [13].
