Question
Chapter 15, Problem 17TYR
Summary Introduction
Introduction:
Pre- and post-ganglionic neurons are the functional components of the central nervous system. They are the neural circuits in which the command system from the brain passes to the preganglionic neurons that emit the neurotransmitter acetylcholine, and this in turn is received by the synaptic cleft of postganglionic nerve fibers. These postganglionic nerve fibers secrete the secondary neurotransmitter like norepinephrine into the target cells, which is received by the adrenergic receptors.

Students have asked these similar questions
a. What percentage of a drug is eliminated after 4 half-lives? Please round to the nearest percent.
b. What will happen to elimination of the drug in the previous question if the system is saturated? explain and show any math involved
If you wanted to reduce the difference between peak and trough levels that occur with repeated administration of a drug, how would you adjust the dose and dose interval without changing the plateau concentration (plateau is the average of peak and trough levels)? Select your answers for both dose and interval. Hint: It may be helpful to think about this problem using an example such as food. How would you eat if you wanted to maintain very steady hunger/satiety levels without changing your total caloric intake?
Options:
A. Dose; Increase dose
B. Dose; Decrease dose
C. Dose; Do not change dose
D. Interval; Increase the interval between doses (give the drug less frequently)
E. Interval; Decrease the interval between doses (give the drug more frequently)
F. Interval; Do not change the interval
What percentage of a drug is eliminated after 4 half-lives? Please round to the nearest percent. Show the math
