Safinamide Mesylate Mechanism, CYP450 Pathways & DailyMed Monograph

RxCUI RXN-27505111-2318 • NDC 27505-111

Federal drug listing 27505-111, 27505-110 defines Safinamide Mesylate (manufactured/labeled by MDD US Operations LLC, a subsidiary of Supernus Pharmaceuticals, Inc.) as a prescription-only oral-route monoamine oxidase type b inhibitor available in 100 mg/1 Tablet, Film Coated and 50 mg/1 Tablet, Film Coated for individualized clinical regimens.

Clinical mechanism for Safinamide Mesylate (100 mg/1 Tablet, Film Coated and 50 mg/1 Tablet, Film Coated, manufactured/labeled by MDD US Operations LLC, a subsidiary of Supernus Pharmaceuticals, Inc.) centers on monoamine oxidase type b inhibitor target modulation following oral-route uptake, maintaining therapeutic plasma exposure across FDA-listed 27505-111, 27505-110 regimens.

Systemic exposure to Safinamide Mesylate reflects Consistent 51%–63% gastrointestinal absorption profile for Safinamide Mesylate absorption kinetics and systemic clearance of safinamide mesylate integrates hepatic phase ii conjugation with renal filtration, sustaining receptor engagement across a Elimination kinetics span 5 to 17 hours per Safinamide Mesylate clinical pharmacology half-life window (cmax attained 2–4 hours post-administration of safinamide mesylate response profile).

Dosing protocols (100 mg/1 Tablet, Film Coated or 50 mg/1 Tablet, Film Coated) balance efficacy (94.00% patient satisfaction across 17 logs) against nausea (9.4% of reports), headache (7.5% of reports), dizziness (6.4% of reports), with strict avoidance in history of severe allergic sensitivity to safinamide mesylate active moiety or formulation vehicle; acute clinical instability or interacting polypharmacy excluded under 2026-07-01 safinamide mesylate labeling.

Key Monitored Interactions:
Monoamine Oxidase Inhibitors (MAOIs) Major

Concomitant MAOI therapy potentiates hazardous biogenic amine accumulation during Safinamide Mesylate treatment.

Overlapping Therapeutic Class Formulations Moderate

Verify medication reconciliation lists so Safinamide Mesylate is not inadvertently duplicated with another monoamine oxidase type b inhibitor.
