The study evaluated changes in blood pressure and heart rate during esketamine administration in patients with and without concomitant tranylcypromine treatment. Results showed that while there were statistically significant increases in blood pressure for patients receiving tranylcypromine, these changes were clinically insignificant. The study suggests that combining esketamine and tranylcypromine at standard doses is safe, but caution should be taken with higher doses of tranylcypromine.
Background (Es)ketamine and monoamine oxidase inhibitors (MAOIs), e.g., tranylcypromine, are therapeutic options for treatment-resistant major depression. Simultaneous administration is currently not recommended because of concern about hypertensive crises. Objective Our objective was to evaluate whether changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) during esketamine administration differed between patients who concomitantly received tranylcypromine and those who did not. Methods This was a retrospective cohort study utilizing cardiovascular monitoring data from inpatients treated for severe depression in unipolar, bipolar, and schizoaffective disorder. Primary outcomes were change in mean BP and HR during the first hour after intravenous or subcutaneous esketamine administration compared with baseline, controlled for confounders. Secondary analyses quantify differences in absolute BP during esketamine treatment and comparisons of BP peaks, temporal effects, and intraindividual comparisons before and after tranylcypromine initiation. Results Our analysis included 509 esketamine administrations in 43 patients, 14 of whom concomitantly received tranylcypromine. Controlling for creatinine and age, mean +/- standard deviation (SD) BP changes were significantly increased by concomitant tranylcypromine treatment (Delta SBP: F[1,503] = 86.73, p < 0.001; Delta DBP: F[1,503] = 55.71, p < 0.001), but HR remained unaffected. Mean SBP change during esketamine administration was 2.96 +/- 18.11 mmHg in patients receiving tranylcypromine (TCP+) and -8.84 +/- 11.31 mmHg in those who did not (TCP-). Changes in DBP were -2.81 +/- 11.20 mmHg for TCP+ and -10.77 +/- 9.13 mmHg for TCP-. Moreover, we found a significant dose-response relationship between tranylcypromine dose and BP (SBP: B = 0.35, standard error [SE] = 0.12, 95% confidence interval [CI] 0.12-0.60, p = 0.004; adjusted R-2 = 0.11, p = 0.008; DBP: B = 0.21, SE = 0.08, 95% CI 0.06-0.36, p = 0.007; adjusted R-2 = 0.08; p = 0.023). Conclusions Although statistically significant changes in BP were identified in patients receiving tranylcypromine and esketamine, these changes were clinically insignificant. Thus, combining esketamine and this MAOI appears to be safe at standard doses. The dose-response relationship calls for caution with higher doses of tranylcypromine.
