Solriamfetol weakly binds to dopamine and norepinephrine transporters but not serotonin transportersLabel2. Solriamfetol does not bind to dopamine, serotonin, norepinephrine, GABA, adenosine, histamine, orexin, benzodiazepines, or muscarinic and nicotinic receptorsLabel.
Solriamfetol is also associated with a mean increase of 21 beats per minute (BPM) in heart rate in patients taking 300mg (twice the maximum recommended dose) and 27 BPM in patients taking 900mg (six times the maximum recommended dose)Label. 300mg of solriamfetol does not increase the QTcF interval to a clinically relevant degreeLabel.
- Mechanism of action
The specific mechanism of action is unknown but it may be through its activity as a dopamine and norepinephrine reuptake inhibitorLabel2.
Target Actions Organism USodium-dependent dopamine transporter Not Available Humans USodium-dependent noradrenaline transporter Not Available Humans - Absorption
Oral bioavailability of solriamfetol is approximately 95%Label. Peak plasma concentration is reached in 2 hours (with a range of 1.25 to 3 hours) in fasted patientsLabel. When solriamfetol is taken with a high fat meal, the time to peak plasma concentration increases to 3 hoursLabel.
- Volume of distribution
199LLabel. Other studies have found the volume of distribution to be 158.2L ± 37.3L in fasted subjects and 159.8L ± 38.9L in fed subjects4.
- Protein binding
13.3% to 19.4% protein bound over a plasma concentration range of 0.059 to 10.1mcg/mLLabel.
- Metabolism
Solriamfetol does not undergo significant metabolism in humans, though less than 1% of solriamfetol is metabolized to N-acetyl solriamfetolLabel2.
- Route of elimination
95% of solriamfetol is recovered in urine unchanged by metabolismLabel. Less than 1% of solriamfetol is recovered as N-acetyl solriamfetolLabel2.
- Half-life
7.1 hoursLabel. Other studies have found the mean half life to be 6.1 ± 1.2 hours in fasted subjects and 5.9 ± 1.2 hours in fed subjects4.
- Clearance
Renal clearance is 18.2L/h and total clearance is 19.5L/hLabel. Other studies have found clearance to be 18.4 ± 4.2L/h in fasted subjects and 18.8 ± 4.2L/h in fed subjects4.
- Adverse Effects
Improve decision support & research outcomesWith structured adverse effects data, including: blackbox warnings, adverse reactions, warning & precautions, & incidence rates.Improve decision support & research outcomes with our structured adverse effects data.- Toxicity
Age, gender, and race do not significantly affect solriamfetol pharmacokinetics and no dose adjustments were made in clinical trials for patients over 65 yearsLabel.
Patients with renal failure experience increases in half life between 1.2 and 3.9 times that in healthy patientsLabel. 21% of solriamfetol was removed by hemodialysis, however time to peak concentration was not affectedLabel.
Solriamfetol is not expected to lead to adverse effects in pregnancyLabel. Maternal and fetal toxicity was seen in animal studies at ≥4 and 5 times the maximum recommended human dose and teratogenicity was seen at 19 and ≥5 times the maximum recommended human doseLabel.
Breastfed infants should be monitored for adverse reactions such as agitation, insomnia, anorexia, and reduced weight gain as solriamfetol is present in breast milkLabel. However, there is no currently available data on the effect of solriamfetol in breast milk on breast fed inantsLabel.
Safety and effectiveness of solriamfetol in pediatric patients has not been established in clinical studiesLabel.
Solriamfetol does not display different safety or effectiveness in geriatric populationsLabel.
Dosage adjustments are recommended for patients with eGFR <60mL/min/1.73m^2 and solriamfetol is not recommended for patients with an eGFR <15mL/min/1.73m^2Label.
