Summary

The study has been designed to assess the effect of cyclooxygenase inhibition on blood pressure, cerebral blood flow, ventilation and renal hemodynamics following chronic intermittent hypoxia exposure.

Conditions

Interventions

OTHER

Intermittent hypoxia

The subjects will receive five days of drug intervention: either non-selective cyclooxygenase (Indomethacin) or selective cyclooxygenase-2 inhibition (Celecoxib) or placebo. On the testing day, the subjects will undergo an acute intermittent hypoxia testing before and six hours of hypoxic chamber exposure mimicking obstructive sleep apnea syndrome.

DRUG

Indomethacin

The subjects will receive five days of drug intervention: either non-selective cyclooxygenase (Indomethacin) or selective cyclooxygenase-2 inhibition (Celecoxib) or placebo. Then they will be tested with an exposure of intermittent hypoxia. Indomethacin: 50 mg, Oral, three times per day for five days.

DRUG

Celecoxib

The subjects will receive five days of drug intervention: either non-selective cyclooxygenase (Indomethacin) or selective cyclooxygenase-2 inhibition (Celecoxib) or placebo. Then they will be tested with an exposure of intermittent hypoxia. Celecoxib: 200 mg, Oral, two times per day for five days with a visually matching sequential placebo in between of two doses.

DRUG

Placebo

The subjects will receive five days of drug intervention: either non-selective cyclooxygenase (Indomethacin) or selective cyclooxygenase-2 inhibition (Celecoxib) or placebo. Then they will be tested with an exposure of intermittent hypoxia. Placebo: Oral, three times per day for five days.
