ABSTRACT
BACKGROUND AND OBJECTIVES:
Viloxazine extended-release (viloxazine ER) capsules (QelbreeTM) is a novel nonstimulant recently approved as a treatment for attention-deficit/hyperactivity disorder in children and adolescents. Here, we determined whether the pharmacokinetics of viloxazine are impacted by consuming the capsule contents sprinkled on applesauce rather than an intact capsule, and the effect of a high-fat meal on the pharmacokinetics of viloxazine ER.METHODS:
This was a randomized, open-label, crossover, three-treatment, three-period study in healthy adults using orally administered single-dose viloxazine ER 200 mg capsules. Subjects consumed (1) an intact capsule after a 10-h fast (control condition); (2) the capsule contents sprinkled on one tablespoon of applesauce; and (3) an intact capsule with a standard high-fat meal. Blood samples were collected for 48 h post-dosing. Relative bioavailability analyses were performed to assess the impact of each test condition against the control condition (intact capsule, fasting). The absence of an impact was indicated if the 90% confidence interval (CI) for the least-squares geometric mean ratio (LSGMR) of maximal concentration (Cmax), the area under the concentration-time curve from time 0 to the last measurable concentration time (AUClast), and the area under the concentration-time curve from time 0 to infinity (AUCinf) were within the predetermined no-difference limits of 80-125%.RESULTS:
Out of 27 enrolled subjects, 25 were included in the pharmacokinetic analysis. The LSGMR (90% CI) for viloxazine ER sprinkled vs. intact were 90.10% (83.35-97.40) for Cmax, 93.71% (89.09-98.57) for AUClast, and 95.37% (89.80-101.28) for AUCinf. The LSGMR (90% CI) for viloxazine ER consumed in the fed state vs. fasting state were 90.86% (84.05-98.21) for Cmax, 89.68% (85.26-94.33) for AUClast, and 92.35% (86.96-98.07) for AUCinf. The 90% CIs of the LSGMRs were within the predetermined no-difference limits of 80-125%. Viloxazine ER was well tolerated, with most adverse events reported as mild.CONCLUSIONS:
These data suggest that viloxazine ER can be consumed sprinkled on applesauce or as intact capsules with or without meals without significantly changing its pharmacokinetics.
