A

F=(area under curve oral x IV)/(area under IV curve x oral dose)

195
Q

what happens with oral bioavailability- why does it decrease with oral

A

High first pass metabolism through the liver leads to decreased serum drug

196
Q

where is absorption of rectum based on pectinate line

A

if below the pectinate line, it can increase bioavailability because of systemic circulation. If it is above the pectinate line, it can go through portal circulation so there is decreased drug

198
Q

What is the volume of distribution and formula

A

It is the theoretical volume occupies by the total amount of drug in the body relative to plasma concentration.

Q

what is the tachyphylactic effect of drug interactions

A

acute decrease in response to a drug after initial or repeated administration.

212
Q

with a competitive antagonist, what happens to the potency and efficacy and an example

A

The curve shifts right, so the potency is decreased but there is no change in efficacy because it can be overcome which the addition of substrate- diazepam and flumazenil

213
Q

with a noncompetitive antagonist, what happens to the potency and efficacy and an example

A

It shifts the curve down, so there is decreased efficacy that cannot be overcome with increased substrate. An example would be- NE and pehnoxybenzamine

214
Q

with partial agonist, what happens to potency and efficacy and an example

A

It acts at the same site as full agonist, but with lower maximal effect, so decreased efficacy and potency is independent- morphine and buprenorphine.
