Explanation:

Pharmacokinetics is the analysis of how the body copes with absorption, distribution, metabolism & excretion of drugs under examination. The impacts and length of the drug's action are also considered.

The four process of pharmacokinetics are absorption, distribution, metabolism and elimination.

1) Absorption - Absorption is the motion of a drug into the blood from its administration site. Many drugs are absorbed through passive absorption, but certain drugs require transportation mediated by the carrier.

2) Distribution - Distribution is the body wide motion of drugs

3) Metabolism - It is the method of transforming a drug throughout the body and make it much more hydrophilic in order for the kidneys to secrete it from the body.

4) Elimination - Excretion is the elimination from the body of the substance. Several drugs are either excreted unchanged or emit as urine or some other form.
