Absorption is the process of delivering a drug into the blood stream. Absorption can be accomplished by administering the drug in a variety of different ways (e.g. orally, rectally, intra-muscularly, subcutaneously, inhalation, topically, etc.).

- Drug Distribution
Drugs diffuse across a cell membrane from a region of high concentration (eg, gastrointestinal fluids) to one of low concentration (eg, blood). Diffusion rate is directly proportional to the gradient but also depends on the molecule’s lipid solubility, size, degree of ionization, and the area of absorptive surface.
Absorption is the first stage of pharmacokinetics and occurs after medications enter the body and travel from the site of administration into the body’s circulation. Distribution is the second stage of pharmacokinetics. It is the process by which medication is spread throughout the body.

Absorption occurs after drugs enter the body and travel from the site of administration into the body’s circulation. Medications can enter the body through various routes of administration. Common routes to administer medications include the following examples: oral (swallowing an aspirin tablet)
Absorption through the buccal or sublingual membranes may be rapid. Absorption through skin is generally slower but produces steady, long-term effect that avoids the first pass effect. However, absorption of medication is affected by blood flow to the skin.

Absorption is the process of moving the medication from the site of administration into the circulation. With the exception of intravenous administration , a medication will need to cross one or more cell membranes before it reaches the circulation.
