Drug Absorption
Drug Absorption
In pharmacology (and more specifically pharmacokinetics), absorption is the movement of a drug into the bloodstream.
Absorption involves several phases. First, the drug needs to be introduced via some route of administration (oral, via the skin, etc.) and in a specific dosage form such as a tablet, capsule, and so on.
In other situations, such as intravenous therapy, intramuscular injection, enteral nutrition and others, absorption is even more straight-forward and there is less variability in absorption and bioavailability is often near 100%.
Absorption is a primary focus in drug development and medicinal chemistry, since the drug must be absorbed before any medicinal effects can take place. Moreover, the drug's pharmacokinetic profile can be easily and significantly changed by adjusting factors that affect absorption.
