                            EXCRETION OF DRUGS

 CHEMICAL PATHWAYS FOR BIOTRANSFORMATION

The pathways of drug metabolism can divided in to:

                        METABOLISING ENZYMES

Metabolism (biotransformation)

Same like metabolism of carbohydrate, protein, lipids, the drug will metabolized by enzymes present in the body.

The conversion of lipid soluble substances or drug in to water soluble compound by enzymatic reaction is called as bio-transformation. It involves alteration of drug molecule.
