An open-label, single-dose, parallel-group study of the effects of chronic hepatic impairment on the safety and pharmacokinetics of desvenlafaxine.
    Clinical therapeutics, 2013, Volume: 35, Issue:6

    Many antidepressants are extensively metabolized in the liver, requiring dose adjustments in individuals with hepatic impairment. Clinical studies indicate that the serotonin-norepinephrine reuptake inhibitor desvenlafaxine is metabolized primarily via glucuronidation, and ∼45% is eliminated unchanged in urine.. The objectives of this study were to assess the pharmacokinetic profile, safety, and tolerability of desvenlafaxine in adults with chronic Child-Pugh class A, B, and C hepatic impairment.. Subjects (aged 18-65 years) with mild (Child-Pugh class A, n = 8), moderate (Child-Pugh class B, n = 8), and severe (Child-Pugh class C, n = 8) hepatic impairment and 12 healthy matched subjects received a single 100-mg oral dose of desvenlafaxine. Disposition of (R)-, (S)-, and (R+S)-enantiomers of desvenlafaxine were examined in plasma and urine. Geometric least squares (GLS) mean ratios and 90% CIs for AUC, AUC0-τ, Cmax, and Cl/F were calculated; comparisons were made by using a 1-factor ANOVA. Safety was evaluated according to adverse events, physical examination, vital signs, and laboratory assessments.. Healthy participants had a mean age of 51 years (range, 36-62 years) and weight of 79.1 kg (range, 52.5-105.0 kg); hepatically impaired participants had a mean age of 52 years (range, 31-65 years) and weight of 80.9 kg (range, 50.2-119.5 kg). In both groups, 67% of participants were male. No statistically significant differences (≥50%) in the disposition of desvenlafaxine were detected between hepatically impaired patients and healthy subjects based on GLS mean ratios for Cmax, AUC0-τ, AUC, or Cl/F (P > 0.05 for each comparison). Median Tmax was similar for all groups (range, 6-9 hours). A nonsignificant increase was observed for desvenlafaxine exposure in patients with moderate or severe hepatic impairment (GLS mean ratios [90% CIs] for AUC, 31% [93.2-184], 35% [96.5-190], respectively). The most common adverse events were nausea (n = 2, healthy subjects; n = 3, hepatically impaired subjects) and vomiting (n = 1, healthy subjects; n = 2, hepatically impaired subjects).. A single 100-mg dose of desvenlafaxine was well tolerated in healthy subjects and hepatically impaired patients. A mild increase in exposure was observed for moderate and severe hepatically impaired subjects (Child-Pugh class B and C).
