Q

Why drugs with short half lives can be given once a day?

A

This is because of the high initial concentration in relation to the EC50.

initial dose has a higher effect that last longer, regardless of the short half life.

Q

why do most drugs follow first order kinetics?

a. Enzymes and sites are saturated.
b. plasma concentration is well below Km ( conc. of drug to saturate half of the receptors).
c. Because the initial concentration are high

A

B.
CL = Vmax x C/Km, since Km is always very high, c can be ignored.
Clearance: Vmax/Km; concentration is less than Km and can be ignored.

Q

A pesticide handler, who is obese with a 40 PPY smoking history wants to lose weight. He admits to you that he eats a lot barbecue meat with cauliflower rice. and likes to barbecue his meat like dark. You recommend, since he is 450 pounds, a weight loss medication that gets metabolized via P450 pathway.

Would you consider higher dose of this medication, with the above risk factors or a lower dose.
. (don’t laugh-answer correctly).

Higher/ lower dose?

A

Higher dose, since he has all the risk factors that lead to induction of P450, quickly metabolizing the drug.

Good luck with the weight loss; may be better than fasting.

Aromatic hydrocarbons in cigarette smoke cause AhR-mediated P450 enzyme induction. • Charcoal-broiled foods and cruciferous vegetables induce CYP1A enzymes. • Industrial workers exposed to some pesticides metabolize certain drugs more rapidly than non-exposed individuals

Q

What is the difference between these two drugs: Raloxifene and Fulvestrant?

a. Fulvestrant is SERM
Raloxifene is SERDS
b. c. Both are the same.
c. Fulvestrant is SERD: it is devoid of estrogen activity. It inhibits dimerization of the estrogen receptor, hence increasing estrogen receptor degradation.
d. Raloxifene is SERD. It is a Modulator of the estrogen receptors and binds and inhibit estrogen receptor in the breast and is an agonist to the estrogen receptors elsewhere.

A

C.
The correct choice.

For D, Raloxifene is SERM and SERD.

72
Q

b. Vitamin C, Zn, copper

c. Vitamin A, Vitamin K and calcium
d. Vitamin K, copper, Zn.

A

C.
Hydroxylation of the proline and lysine and requires Vitamin C.
Lysyl oxidse requires copper.

b. PGE2, 
c. PGE2, PGD2, PGl2.
d PEG2 and IL1
A

d.

Q

During acute inflammation, coagulation and fibrinolytic systems, complement, and Kinin systems are activated by which of the following activated protein;

a. Factor II
b. Factor III
c. Factor IV
d. Factor X
e. Factor XII

A

E

Factor XII is formed in the liver in an inactivated form and gets activated upon exposure to subendothelial and tissue collagen exposure and, in turn, activates coagulation and fibrinolytic systems,complement, and Kinin systems.
