Factors that affect absorption of drugs
aqueous and lipid solubility
concentration
area of absorbing surface
contact time with absorbing surface
route of administration
1st pass metabolism
when a drug passes through the liver the bioavailability significantly decreases
- amount of available drug in the blood flow after passing through the liver
Enteropherpatic shunting
considerable amount of drugs pass from liver to bile and from bile to small intestine but then travel through hepatic portal back to liver then into the blood flow
Bioavailability
Amount of drug available when reaches the systemic circuit
Low vs high volume of distribution
Low = stuck in the vacucirculation
High = high lipid solubility and able to pass to many areas of the body
pro drugs
in inactive form until metabolised by the body is then in active form
Half life
time it takes for the drugs active substance to decrease by half
