Pharmacokinetics

Absorption

the process of movement of unchanged drug from the site of administration to systemic circulation.

Distribution

the drug might also additionally then reversibly leave the blood- circulation and distribute into the interstitial and intracellular fluids.

Metabolism

Metabolism is the sum of an organism's chemical reaction 

-It is an emergent property of life that arises from interactions between molecules within the cell

Elimination

Using statistics of pharmacokinetic parameters, clinicians can layout Optimal drug regimens, consisting of the path of administration, the dose The frequency, and the length of remedy.
