    Medroxyprogesterone acetate improved sleep apnea symptoms in some patients, reducing daytime sleepiness and apneas. Responders had lower oxygen levels before treatment, and symptoms returned after stopping the drug.

    Area of Science:

    • Sleep Medicine
    • Pharmacology

    Background:

    • Obstructive sleep apnea syndrome (OSAS) is a common disorder.
    • Current treatments for OSAS have limitations.

    Purpose of the Study:

    • To assess the efficacy of medroxyprogesterone acetate in treating OSAS.
    • To identify predictors of treatment response.

    Main Methods:

    • Nine adult patients with OSAS received medroxyprogesterone acetate (60-120 mg/day).
    • Clinical symptoms and obstructive apneas during sleep were monitored.
    • Arterial oxygen tension was measured during wakefulness.

    Main Results:

    • Four of nine patients responded to treatment, showing reduced daytime sleepiness, edema, and fewer apneas.

  • Discontinuation of therapy led to symptom recurrence in responders.
  • Lower baseline arterial oxygen tension distinguished responders from non-responders.
  • Two responders experienced side effects (alopecia, decreased libido).

    • Conclusions:

    • Medroxyprogesterone acetate may benefit a subgroup of OSAS patients.
    • Lower resting arterial oxygen tension may predict positive response.
    • Further research is warranted to explore this therapeutic option.
