Detailed explanation-1: -Pharmacokinetics is the aspect of pharmacology dealing with how drugs reach their site of actionand are removed from the body. The following processes govern the rate of accumulation and removal of drug from an organism–absorption, distribution, metabolism, and excretion.
Detailed explanation-2: -Following administration, the drug must be absorbed and then distributed, usually via vessels of the circulatory and lymphatic systems; in addition to crossing membrane barriers, the drug must survive metabolism (primarily hepatic) and elimination (by the kidney and liver and in the feces).
Detailed explanation-3: -Pharmacokinetics (PK) is the study of how the body interacts with administered substances for the entire duration of exposure (medications for the sake of this article). This is closely related to but distinctly different from pharmacodynamics, which examines the drug’s effect on the body more closely.
Detailed explanation-4: -Absorption, distribution, metabolism, and excretion are processes that together describe a drug’s overall disposition via pharmacokinetics, or what the body does to a drug. ADME data can be collected at many stages in a drug’s development pipeline.
