What does absorption refer to in pharmacology?

Absorption in pharmacology specifically refers to the process by which a substance, such as a drug, is taken into the bloodstream or circulation after administration. This step is crucial as it determines how much of the medication is available to exert its therapeutic effects. The effectiveness of different routes of administration (like oral, intravenous, intramuscular, etc.) influences the rate and extent of absorption, which ultimately impacts how well a drug works in the body.

Understanding absorption is essential for medication aides, as it informs important aspects of medication administration, such as timing, dosage adjustments, and potential side effects. Effective absorption ensures that the active ingredients of the medication reach the target site in the body where they can be utilized effectively.
