What is the mechanism of action of Z-drugs?
Binds to benzodiazepine binding sites on GABAA receptors, preferentially the α2 subunit. Acts as an agonist of GABAA receptors to produce anxiolytic effect.

What are the clinical uses of GABAB antagonists?
Prevents seizures (antiepileptic)
What are the uses of drugs that modulate 5-HT transmission?
- Antidepressants (e.g. SSRIs)
- Antipsychotics
- Antiemetics (5-HT3 antagonists)
- Migraine (5-HT1D agonist)
