Introduction to Levomilnacipran Hydrochloride
Levomilnacipran hydrochloride, marketed under the brand name Fetzima, is a serotonin-norepinephrine reuptake inhibitor (SNRI) approved by the FDA for the treatment of major depressive disorder (MDD) in adults. Here, we will delve into the clinical trials, market analysis, and projections for this medication.
Clinical Trials Overview
The efficacy and safety of levomilnacipran hydrochloride were established through several clinical trials.
Pivotal Studies
- Three 8-week, randomized, double-blind, placebo-controlled studies were conducted. These included two fixed-dose studies and one flexible-dose study involving adult outpatients aged 18-78 years who met the DSM-IV-TR criteria for MDD[1][3].
- In these studies, patients received levomilnacipran at doses of 40 mg, 80 mg, or 120 mg once daily. The flexible-dose study allowed doses to range from 40 mg to 120 mg, with 21%, 34%, and 44% of patients receiving 40 mg, 80 mg, and 120 mg, respectively, at the end of the treatment[1][3].
Efficacy
- Levomilnacipran demonstrated superiority over placebo in all three studies, as measured by the improvement in depressive symptoms using the Montgomery-Åsberg Depression Rating Scale (MADRS) total score. It also showed improvement on the Sheehan Disability Scale functional impairment total score[1][3].
Safety and Adverse Events
- The safety profile of levomilnacipran was evaluated in 2,655 patients. Common adverse events included nausea, constipation, hyperhidrosis, heart rate increased, erectile dysfunction, tachycardia, vomiting, and palpitations. Dose-related adverse events included erectile dysfunction and urinary hesitation[3].
- The drug showed a modest QTc prolongation effect, and recommendations include monitoring blood pressure and heart rate before and during treatment. Dose adjustments are recommended for patients with moderate and severe renal impairment and when co-administered with strong CYP3A4 inhibitors[3].
