Drug Absorption after Oral Administration

Solid dosage forms have to go though several steps before the drug is absorbed into the systemic circulation.

a-Disintegration

b-Dissolution

c-Absorption

The rate constant that describes the overall absorption process is the absorption rate constant. The absorption rate constant after administration of different dosage forms of the same drug can be different because of the differences in the formulation characteristics.
