2.interferron gamma 1-b used for the treatment of?
3.what does a catalyst do?
4.disappearance of most drugs from the plasma follow first order kinetics, which means that
a. the rate of disappearance is independent of the amoiunt of drugn left at anytime
b. the rate of disappearance is proportional to the amount of drug left at any time
c. the disposition mechanism are saturated
d.the plasma t1/2 will have a high value.
5. if Pka of a base = PH+log-conc.ionized, what is the portion of epehedrine conc.nonionized?
Pka = 9.6 in the nonionized from in the plasma with Ph = 7.6
a. 1% b. 10% c.50% d. 90% e. 99%.
plz. anser this with example.

2.interferron gamma 1-b used for the treatment of? chronic granulomatous disease

3.what does a catalyst do? catalyse a reaction?!

4.disappearance of most drugs from the plasma follow first order kinetics, which means that
a. the rate of disappearance is independent of the amoiunt of drugn left at anytime
b. the rate of disappearance is proportional to the amount of drug left at any time
c. the disposition mechanism are saturated
d.the plasma t1/2 will have a high value.

because -dC/dt=kC

5. if Pka of a base = PH+log-conc.ionized, what is the portion of epehedrine conc.nonionized?
Pka = 9.6 in the nonionized from in the plasma with Ph = 7.6
a. 1% b. 10% c.50% d. 90% e. 99%.
pH-pKa=-2=log(base/sel) => base/sel=0.01
plz. anser this with example.

Correct me!
