Q

Precautions of TCA use.

A

Prostatic hypertrophy - may precipitate urinary retention
Hyperthyroidism - may have enhanced response to TCAs
Epilepsy - TCAs may increase risk of seizures (so may depression)
Coronary heart disease - TCAs may precipitate angina
May prolong Q-T interval
Orthostatic hypotension may be exacerbated.
High abuse potential.

20
Q

MOA of Agomelatine:

A

Unclear, Melatonin receptor agonist (M1 and M2) and 5HT receptor antagonist.

21
Q

Precautions for Agomelatine:

A

Combination with potent CYP1A2 inhibitors - may increase agomelatine concentration.
Bipolar disorder
