Q

What effect can a drug have on release?

A

Inhibits release

17
Q

What is the agonist effect?

A

Triggers processes

18
Q

What is the antagonist effect?

A

Block receptor

19
Q

What 4 effects can a drug have on deactivation?

A

Produce more enzyme
Reduce production of enzymes so there is less removal
Disrupt reuptake
Suppress certain enzymes

20
Q

What is half-life?

A

21
Q
