Deroximel DR Capsule (Enteric Coated Pellets) 231 mg
Deroximel DR Capsule (Enteric Coated Pellets) 231 mg Uses, Dosage, Side Effects, Food Interaction and all others data.
Multiple Sclerosis (MS) is a chronic, debilitating neurological disease that can lead to profound cognitive and physical symptoms, severely affecting quality of life. It is the main cause of neurological disability not caused by trauma in the young adult population of both North America and Europe. Relapsing-remitting forms of MS lead to neurological symptoms that resolve and recur periodically. More than 80% of patients suffering from this disease have relapsing-remitting MS.
Deroximel DR Capsule (Enteric Coated Pellets) 231 mg is a new drug from the fumarate class formulated to treat various relapsing forms of MS. This drug is bioequivalent to Dimethyl fumarate(initially manufactured in 2013), but is less likely to cause gastrointestinal side effects, owing to its unique chemical structure. Deroximel DR Capsule (Enteric Coated Pellets) 231 mg was formulated by Alkermes in collaboration with Biogen, and approved by the FDA on October 30, 2019.
Deroximel DR Capsule (Enteric Coated Pellets) 231 mg relieves the neurological symptoms of relapsing MS with less gastrointestinal effects than its bioequivalent counterpart, dimethyl fumarate. It is important to note that diroximel fumarate can cause angioedema, anaphylaxis, hepatotoxicity, flushing, lymphopenia, and Progressive Multifocal Leukoencephalopathy (PML).

Uses
Deroximel DR Capsule (Enteric Coated Pellets) 231 mg is a drug used for the treatment of relapsing forms of Multiple Sclerosis (MS).
Deroximel DR Capsule (Enteric Coated Pellets) 231 mg is indicated for the treatment of relapsing forms of multiple sclerosis (MS) in adults; specifically active secondary progressive disease and clinically isolated syndrome, as well as relapsing-remitting MS.
Deroximel DR Capsule (Enteric Coated Pellets) 231 mg is also used to associated treatment for these conditions: Active secondary progressive Multiple Sclerosis, Clinically Isolated Syndrome (CIS), Relapsing Remitting Multiple Sclerosis (RRMS)
How Deroximel DR Capsule (Enteric Coated Pellets) 231 mg works
Currently, the mechanism of action of this drug in MS is not fully understood. Deroximel DR Capsule (Enteric Coated Pellets) 231 mg is hypothesized to regulate cell signaling pathways, causing beneficial immune and neuroprotective effects. Monomethyl fumarate (MMF) is the active metabolite of diroximel fumarate, and activates the nuclear factor (erythroid-derived 2)-like 2 (Nrf2) pathway in humans. This pathway occurs as a response to oxidative stress in cells.
In addition to the above, MMF is a nicotinic acid receptor agonist in the laboratory setting. The relevance of this finding to the treatment of MS is unknown at this time. The mechanism by which this drug leads to less gastrointestinal effects is purported to be due to its lack of a methanol leaving group in its chemical structure, and substitution with inert 2-hydroxyethyl succinimide.
Toxicity
Currently, an MSDS for diroximel fumarate is unavailable. The MSDS for its bioequivalent counterpart, dimethyl fumarate, indicates an oral LD50 of 2,240 mg/kg in rats.
There is no information regarding overdose on the FDA label for diroximel fumarate. Cases of overdose with its bioequivalent counterpart, dimethyl fumarate, have been reported in the literature, and symptoms reflect the adverse effects of this drug. These symptoms include nausea, vomiting, diarrhea, and flushing, among others. Currently there is no antidote to an overdose with diroximel fumarate or dimethyl fumarate. Symptomatic and supportive management are the only options up to this date if an overdose should occur.
Food Interaction
- Avoid alcohol.
- Take with or without food. If taken with food, the meal/snack should contain no more than 700 calories and no more than 30 g fat. Taking diroximel fumarate with food may reduce the adverse effect of flushing.
Volume of Distribution
The apparent volume of distribution ranges from 72L to 83L. Monomethyl fumarate (MMF), the active metabolite of diroximel fumarate, crosses the blood brain barrier.
Elimination Route
Deroximel DR Capsule (Enteric Coated Pellets) 231 mg is rapidly absorbed in the gastrointestinal tract following administration, like its bioequivalent drug, dimethyl fumarate. The median Tmax of monomethyl fumarate (MMF) after oral administration ranges from 2.5-3 hours with a mean Cmax of 2.11 mg/L. The bioequivalent drug, dimethyl fumarate, administered to healthy volunteers also shows a similar mean Tmax and Cmax.
The average steady state concentration of this metabolite is estimated at 8.32 mg.hr/L after it is administered twice a day in patients with MS. The mean AUC0–∞ of the active metabolite is 88mg × min L−1. Food appears to significantly reduce the Cmax of diroximel fumarate's active metabolite, MMF, when compared to administration in the fasted state.
Half Life
The terminal half-life of monomethyl fumarate (MMF), diroximel fumarate's active metabolite, is estimated to be 1 hour.
Clearance
No clearance information is available on the FDA label for diroximel fumarate, however, clinical study results for its active metabolite, monomethyl fumarate show a mean apparent total clearance from the plasma after oral administration of 1.54 mgL−1.
Elimination Route
Monomethyl fumarate is eliminated as carbon dioxide through expired breath. Negligible amounts, under 0.3% of the ingested dose, are measured in urine. The inactive metabolite, 2-hydroxyethyl succinimide (HES), representing 58-63% of the ingested dose, is excreted in urine.
