Multiple choice
  1. Tryptamine

  2. Melatonin

  3. Auxins

  4. Pindolol

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Pindolol is a nonselective beta blocker with partial beta-adrenergic receptor agonist activity. It possesses ISA (Intrinsic Sympathomimetic Activity). This means that pindolol, particularly in high doses, exerts effects like epinephrine or isoprenaline (increased pulse rate, increased blood pressure, bronchodilation), but these effects are limited.
