Bioavailability/Bioequivalence Detection
Bioavailability refers to the extent and rate at which the active pharmaceutical
ingredients or active parts of the drugs are absorbed and available at the site of action
of the drug action. It is an indicator reflecting the degree and speed of absorption of
the active ingredient into the body and has become an important means to evaluate the
quality of preparations. It is generally divided into absolute bioavailability and
relative bioavailability. Absolute bioavailability refers to the relative amount of the
active ingredient of the drug absorbed into the body circulation obtained by
intravenous preparations (usually considered as 100% ) as the reference preparations;
relative bioavailability refers to the relative amount of active ingredients absorbed
into the systemic circulation by preparations administered by other nonintravenous
routes (such as tablets and oral solutions). If the bioavailability of two drug products
is similar, the drug products are called bioequivalent.
CD Formulation laboratory is cGMP-compliant and equipped with state of the art
analytical instruments. We have experienced analysis experts who can work with our
