Excretion: Finally, the drug and its metabolites are removed from the body. The kidneys are the primary organs for excretion via urine, though drugs can also be cleared through bile, sweat, or breath. Pharmacodynamics: What the Drug Does to the Body

Pharmacology is built on two fundamental pillars: pharmacokinetics (PK) and pharmacodynamics (PD). Understanding these concepts is essential for determining how drugs move through the body and how they exert their therapeutic effects. While they are distinct fields of study, they are deeply interrelated and together dictate the clinical outcome of any drug therapy.

Dose-Response Relationship: PD examines the relationship between the concentration of the drug at the target site and the intensity of the resulting effect. This help determines the therapeutic window—the range between a dose that is effective and a dose that becomes toxic. Excretion: Finally, the drug and its metabolites are

Distribution: Once in the blood, the drug is carried to various tissues and organs. Distribution depends on blood flow, the drug’s ability to cross cell membranes (like the blood-brain barrier), and its tendency to bind to plasma proteins.
