Application
Cromakalim has been used:
- as a potassium channel agonist to study its response to an acute increase in downstream pressure in rat lymphatic vessels.
- as a potassium channel opener to study its effects on the release of transmitters from adrenergic nerves in rat vas deferens.
- as a potassium channel activator to study its effects on the release of transmitters from purinergic and cholinergic nerves in the rat detrusor muscle.
Biochem/physiol Actions
Cromakalim is an activator of the potassium channel. It is involved in the relaxation of the vascular smooth muscles. Cromakalim exhibits anti-hypertensive activity.

The cardiac electrophysiologic effects of the potassium channel activators cromakalim, pinacidil and nicorandil were determined in anesthetized open-chest normotensive dogs using conventional surface electrogram recording techniques. Intravenous administration of cromakalim (0.025-0.5 mg/kg), pinacidil (0.1-2.0 mg/kg) and nicorandil (0.1-2.5 mg/kg) produced
