    Suloctidil demonstrated potent antispasmodic effects on both peripheral and cerebral blood vessels. It effectively inhibited induced vasospasms, outperforming other tested agents in canine and rabbit models.

    Area of Science:

    • Pharmacology
    • Cardiovascular Science
    • Neuroscience

    Background:

    • Peripheral and cerebral vasospasms pose significant clinical challenges.
    • Existing antispasmodic agents have limitations in efficacy and application.

    Purpose of the Study:

    • To evaluate the in vivo antispasmodic activity of suloctidil.
    • To compare suloctidil's efficacy against established vasodilators.

    Main Methods:

    • Utilized perfused dog hind limb preparation to assess peripheral circulation.
    • Investigated cerebral circulation using rabbit pial arteries.
    • Induced vasospasms with norepinephrine, angiotensin, and BaCl(2).

    Main Results:

    • Suloctidil significantly inhibited norepinephrine- and angiotensin-induced vasospasms in dogs.

  • Suloctidil exhibited greater potency than cinnarizine and papaverine.
  • Suloctidil rapidly alleviated BaCl(2)-induced spasms in rabbit pial arteries, where papaverine and vincamine were ineffective.

    • Conclusions:

    • Suloctidil possesses significant in vivo antispasmodic properties on peripheral and cerebral circulations.
    • Suloctidil demonstrates superior efficacy compared to papaverine and cinnarizine in specific vasospasm models.
    • Suloctidil represents a promising therapeutic agent for vasospastic conditions.
