Subclinical ergotism.

H Dige-Petersen, N A Lassen, I Noer

    Lancet (London, England)
    |July 9, 1977
    PubMed
    Summary

    Regular ergotamine use can lower blood pressure in the feet, potentially causing arterial issues. Stopping ergotamine treatment normalized foot blood pressure in patients within nine days.

    Area of Science:

    • Vascular Medicine
    • Pharmacology

    Background:

    • Ergotamine is frequently used for vascular headaches.
    • Long-term ergotamine use may affect peripheral circulation.

    Purpose of the Study:

    • To investigate the impact of chronic ergotamine intake on peripheral systolic blood pressure.
    • To assess the reversibility of ergotamine-induced changes in foot circulation.

    Main Methods:

    • Systolic blood pressure was measured at the ankle and first toe in 30 patients with a history of regular ergotamine use (>1 year).
    • A subgroup of 13 patients discontinued ergotamine treatment.
    • Peripheral blood pressure was monitored after cessation of ergotamine.

    Main Results:

    • All patients exhibited low-normal or abnormal foot systolic blood pressures.
    • Following cessation of ergotamine, distal blood pressures significantly increased.
    • Normal distal pressures were observed by the ninth day after stopping ergotamine.

    Conclusions:

    • Chronic ergotamine use is associated with reduced peripheral systolic blood pressure in the feet.
    • Discontinuation of ergotamine leads to a rapid and significant recovery of distal circulation.
    • These findings suggest ergotamine can induce reversible peripheral arterial vasoconstriction.
