(Effect of combination treatment of atomoxetine and oxybutynin for Japanese patients with obstructive sleep apnea syndrome)

Effect of combination treatment of atomoxetine and oxybutynin

18

Atomoxetine + Oxybutynin first group: total 9 (1 exclusion) male 7 female 2 (1 exclusion), age 49-65 No-med first group: total 9 male 8 female 1, age 47-65

Consent obtained :18 Enrollment:18 ATO + OXY first group: 9 (exclude 1) ATO + OXY 8 to No medicine(med) 8 No med first group: 9 No med 9 to ATO + OXY 9 Analysis: ATO + OXY first group 8 , no med first group 9

Mild adverse events: 1case (vomiting)

Primary endpoints: AHI ( No significant difference) Secondary endpoints: lowest SPO2 value (no significant difference), minimum SPO2 time (no significant difference) sleep architecture (REM sleep p<0.0001, sleep efficiency p=0.02)

Contrary to previous reports, ATO and OXY combined therapy did not significantly improve AHI in Japanese OSA. Sleep architecture showed significant changes, which could be attributed to differences in the metabolic capacity of Asians for ATO.
