Patients with obstructive sleep apnea who receive drug therapy for cardiovascular disease may experience resistant hypertension, arrhythmias, or more severe heart failure, and many of the drugs used to treat these conditions are substrates for P-glycoprotein (P-gp) transporters. Therefore, we sought to determine if intermittent hypoxia, which mimics obstructive sleep apnea, would upregulate myocardial and hepatic P-gp expression and Abcb1a and Abcb1b messenger RNA (mRNA) expression (genes that encode for P-gp) in an animal model.
