Q

Interactions for amitriptyline?

A

Main issues - hypotension, hyponatraemia, constipation.

* Amantadine (a weak dopamine agonist) - increases risk of hypotension
* Amlodipine - increases risk of hypotension
* Baclofen - hypotension
* Thiazide diuretics - hypotension and hyponatraemia
* B blockers (atenolol, bisoprolol) - hypotension
* Carbamazepine - decreases exposure to amitriptyline
* Chlordiazepoxide - both this and amitriptyline = have depressive effects
* Citalopram - hyponatraemia
* Clozapine - an antipsychotic. this + ami = cause constipation
* Lithium - neurotoxicity
* Oxybutynin - ++ antimusc effects

Q

Impact of tamsulosin on falls?

A
  • For alpha1-selective adrenoceptor blockers, prescription potentially inappropriate (STOPP criteria) in elderly:
  1. in those with symptomatic orthostatic hypotension or micturition syncope (risk of precipitating recurrent syncope)
  2. in those with persistent postural hypotension i.e. recurrent drop in systolic blood pressure ≥ 20 mmHg (risk of syncope and falls).

Due to hypotension and risk of syncope – increase risk of falls
