- Mechanism of action
Safinamide is a unique molecule with multiple mechanisms of action and a very high therapeutic index. It combines potent, selective, and reversible inhibition of MAO-B with blockade of voltage-dependent Na+ and Ca2+ channels and inhibition of glutamate release. Safinamide has neuroprotective and neurorescuing effects in MPTP-treated mice, in the rat kainic acid, and in the gerbil ischemia model.
Target Actions Organism AAmine oxidase [flavin-containing] B antagonistHumans - Absorption
Rapid with peak plasma concentrations ranging from 2 to 4 h, total bioavailability is 95%. Food prolonged the rate and did not affect the extent of absorption of safinamide.
- Volume of distribution
1.8 litres/kg
- Protein binding
88–90%
- Metabolism
The principal step is mediated by amidases which have not been identified, and produces safinamide acid. It is also metabolized to O-debenzylated safinamide and N-delkylated amine. The N-dealkylated amine is then oxidized to a carboxylic acid and finally glucuronidated. Dealkylation reactions are mediated by cytochrome P450s (CYPs), especially CYP3A4. Safinamide acid binds to organic anion transporter 3 (OAT3), but no clinical relevance of this interaction has been determined. Safinamide also binds to ABCG2 transiently. No other transporter affinities have been found in preliminary studies.
- Route of elimination
76% renal, 1.5% faeces
- Half-life
22 h
- Clearance
total oral clearance of plasma , which accounts for parent safinamide as well as metabolites, was on average only 17.53 ± 2.71 ml/h × kg

Drug Interaction Integrate drug-drug
interactions in your software1,2-Benzodiazepine The risk or severity of CNS depression can be increased when Safinamide is combined with 1,2-Benzodiazepine. Abaloparatide Safinamide may increase the orthostatic hypotensive activities of Abaloparatide. Abametapir The serum concentration of Safinamide can be increased when it is combined with Abametapir. Abciximab The risk or severity of bleeding and hemorrhage can be increased when Safinamide is combined with Abciximab. Abemaciclib Safinamide may decrease the excretion rate of Abemaciclib which could result in a higher serum level. - Food Interactions
- Avoid excessive or chronic alcohol consumption. Ingesting alcohol may increase the sedative effects of safinamide.
- Avoid St. John's Wort. This herb may increase the risk of serotonin syndrome, and therefore, concomitant use is contraindicated.
- Avoid tyramine-containing foods and supplements. Avoid foods containing high amounts of tyramine (>150mg) as these foods may cause a significant elevation in blood pressure. Tyramine-containing foods include cheese, red wine, fava beans, pickled food, cured food, and alcoholic beverages.
- Take at the same time every day.
- Take with or without food.
