Absorption of Drugs

Absorption is the process by which drug molecules cross biological membranes.

It is usually associated with oral drugs and their absorption through the GIT.

It also occurs by subcutaneous, intra muscular and transdermal routes of administration of drugs. 

However, the absorptive process does not occur during direct injection of drug by intravenous or intra arterial injection.
