Adenosine stimulates respiration in man.

A H Watt, P A Routledge

    British Journal of Clinical Pharmacology
    |November 1, 1985
    PubMed
    Summary

    Adenosine administration significantly increased respiration depth in healthy subjects. This study investigated the dose-related respiratory effects of adenosine, exploring potential underlying mechanisms.

    Area of Science:

    • Physiology
    • Pharmacology

    Background:

    • Adenosine is a naturally occurring nucleoside with diverse physiological roles.
    • Understanding adenosine's effects on the respiratory system is crucial for its therapeutic applications.

    Purpose of the Study:

    • To investigate the respiratory effects of intravenous adenosine boluses in healthy humans.
    • To determine the dose-response relationship of adenosine on respiratory parameters.

    Main Methods:

    • Nine healthy human subjects received a series of intravenous adenosine boluses.
    • Respiratory parameters were monitored to assess the effects of adenosine administration.

    Main Results:

    • Adenosine caused a significant, dose-related increase in respiration.
    • The primary driver of increased respiration was a greater depth of breathing.

    Conclusions:

    • Intravenous adenosine administration elicits a dose-dependent stimulation of respiration in humans.
    • Increased tidal volume is the main contributor to adenosine-induced hyperpnea, suggesting central respiratory modulation.
