Dimethyl fumarate, a fumaric acid derivative, is a medication made from fumaric acid. Fumaric acid was originally synthesized in the 1950s for the treatment of psoriasis. Fumaric acid functions as a dicarbonic acid in the citric acid cycle. Dimethyl fumarate is a lipophilic ester of fumaric acid and is rapidly metabolized in the body. It is used to treat multiple sclerosis and psoriasis. Doctors use dimethyl fumarate as a generic drug. This means it has the same efficacy as brand-name drugs but is generally less expensive.
Key Takeaways
- Dimethyl fumarate is derived from fumaric acid. It is a medication used to treat multiple sclerosis and psoriasis.
- This generic drug has similar efficacy to Tecfidera. Its price is generally lower, making it more accessible to patients.
- Dimethyl fumarate can reduce swelling and protect nerve cells. It helps reduce relapses in patients with multiple sclerosis.

The Relationship Between Fumaric Acid and Dimethyl Fumarate
Fumaric acid and dimethyl fumarate are closely related. Fumaric acid is a dicarboxylic acid containing a double bond. Fumaric acid reacts with methanol to form dimethyl fumarate. This reaction adds a methyl group to the compound. They belong to the same class of compounds but have different uses. The conversion between fumaric acid and dimethyl fumarate demonstrates that a simple food additive can be transformed into a potent drug. It links a basic compound to its pharmaceutical form. Fumaric acid and dimethyl fumarate help treat diseases such as multiple sclerosis and psoriasis.
Uses of Dimethyl Fumarate
Multiple Sclerosis Treatment
Doctors prescribe dimethyl fumarate to patients with relapsing-remitting multiple sclerosis (MS). This medication can slow disease progression and reduce relapses. Many countries consider dimethyl fumarate safe and effective for MS. The European Union allows doctors to use it as a first-line oral treatment for relapsing-remitting MS. The U.S. Food and Drug Administration (FDA) has also approved it for the treatment of relapsing-remitting MS.
Dimethyl fumarate helps treat MS by reducing swelling and protecting nerves. Studies have shown that it can reduce new brain lesions and slow the progression of disability. The DEFINE and CONFIRM studies found that patients taking dimethyl fumarate experienced fewer relapses and improved health.
| Study | Efficacy Measure | Result |
|---|---|---|
| DEFINE | Proportion of patients with MS relapse | Effective at 2 years |
| CONFIRM | Annualized relapse rate | Effective compared to placebo |
| DEFINE | Reduced disability progression | Observed versus placebo |
Researchers tested dimethyl fumarate in multiple trials. These studies found it to be safe, effective, and superior to placebo. The CONFIRM and DEFINE trials showed that patients taking dimethyl fumarate had lower relapse rates and better MRI results.
| Trial Design | Results |
|---|---|
| Phase IIb trial on oral fumarate in relapsing-remitting MS | Antiinflammatory effects shown by fewer new lesions and good safety. More long-term studies were needed. |
| Retrospective study of MRI scans from a phase IIb trial | BG-12 lowered new Gd+ lesions and stopped them from turning into T1-hypointense lesions compared to placebo. |
| Phase III study (CONFIRM trial) | BG-12 and glatiramer lowered relapse rates and improved MRI results compared to placebo. |
| Phase III study (DEFINE study) | Both BG-12 regimens lowered the number of relapses and annual relapse rate compared to placebo. |
| Ongoing phase III extension study (ENDORSE) | Safety and tolerability of dimethyl fumarate matched earlier studies. No new safety problems were found. |
Psoriasis and Other Indications
Doctors use dimethyl fumarate to treat psoriasis. Psoriasis causes red, scaly plaques on the skin. Dimethyl fumarate can clear the scales from the skin and reduce swelling. A large trial involving more than 700 patients showed that dimethyl fumarate was as effective as other treatments. Doctors used PASI and PGA scores to assess improvement. Patients experienced improved skin condition and felt healthier.
Dimethyl fumarate can be used alone to treat psoriasis without needing to be combined with other medications. Therefore, it is a good option for many patients.
Industrial and Preservative Uses
Dimethyl fumarate is not only a pharmaceutical product. Factories also use it for other purposes. It can prevent leather goods from becoming moldy, especially during transport in humid weather. Workers place small sachets of dimethyl fumarate in boxes to keep shoes, bags, and leather goods dry and mold-free.
Dimethyl fumarate is also used in food factories. It helps control acidity, adds flavor, and promotes bread fermentation. In animal feed, it keeps feed fresh and helps animals digest food better. Dimethyl fumarate is used in factories to enhance the strength and lifespan of resins and plastics.
How Fumaric Acid Dimethyl Fumarate Works
Mechanism of Action
Dimethyl fumarate works by altering how cells respond to stress and swelling. Scientists have discovered that this drug blocks signals that lead to swelling and damage. It inhibits specific pathways associated with Toll-like receptors and ubiquitin-binding enzymes.
Researchers have found that dimethyl fumarate (DMF) can prevent the body from producing excessive pro-inflammatory cytokines. It does this by blocking pathways associated with Toll-like receptors (TLRs) and ubiquitin-binding enzymes. When these signals are blocked, the production of pro-inflammatory cytokines in the body decreases. This is crucial for treating autoimmune diseases such as multiple sclerosis.
Dimethyl fumarate also helps protect cells from damage. It promotes the production of more beneficial proteins in the body. These proteins can fight harmful molecules and reduce swelling. The drug can also alter how genes function in brain cells, thus helping to suppress brain swelling.
| Evidence Type | Description |
|---|---|
| Cytoprotective and Anti-inflammatory Properties | Dimethyl fumarate helps protect cells and lowers swelling. This helps treat relapsing multiple sclerosis. |
| Mechanism of Action | The medicine works in many ways to help the immune system stay balanced. |
| Induction of Anti-inflammatory Proteins | It changes glutathione levels to make more haem oxygenase-1. This helps the immune system work better. |
| Regulation of Gene Expression | Dimethyl fumarate changes histone deacetylases in astrocytes. This may turn on Nrf2 and lower swelling. |
Effects on the Immune System
Fumaric acid dimethyl fumarate changes how the immune system acts. It lowers the number of cells that cause swelling and harm. These cells include T cells, B cells, and other immune cells.
- Dimethyl fumarate lowers the number of proinflammatory T cells (CD8+, CD4+), B cells (CD19+), NK cells (CD56dim), plasmacytoid DCs, and eosinophils.
- It makes T cells stick less to other cells, so they do not move as much.
- In mice, it lowers integrin α4 on T and B cells. This means mice get sick later and have fewer symptoms in EAE.
Doctors see that this medicine helps the immune system stay balanced. It does not stop the immune system from working. Instead, it helps the body fight disease in a safer way.
| Mechanism | Effect |
|---|---|
| Anti-inflammatory properties | Helps treat relapsing multiple sclerosis by lowering swelling. |
| Restores immune balance | Works in many ways to help treat MS. |
Generic Dimethyl Fumarate
What are generic drugs?
Generic drugs have the same main ingredient as brand-name drugs. They must have the same efficacy and work in the body in the same way. The U.S. Food and Drug Administration (FDA) reviews generic drugs to ensure their safety and effectiveness. After the patent for a brand-name drug expires, pharmaceutical companies can produce generic versions. This makes the medication available to more people.
Generic drugs may differ from brand-name drugs in appearance, such as color, shape, or packaging. However, they must still adhere to strict quality and safety standards. Doctors trust generic drugs because they provide the same efficacy as the original brand-name drug.
Comparison of Brand-Name and Generic Drugs
Doctors sometimes have to choose between brand-name and generic drugs. Both are used to treat the same health problems. Tecfidera is a brand-name drug for dimethyl fumarate. Generic dimethyl fumarate has the same main ingredient. Patients with multiple sclerosis or psoriasis can use either one.
Here is some important information about the differences between the two:
- Generic dimethyl fumarate usually costs much less than the brand.
- Generics can be 80 to 85% cheaper than brand-name drugs.
- Both kinds must follow the same safety and quality rules.
- Doctors and pharmacists say both are safe and work well.
| Feature | Brand-Name (Tecfidera) | Generic Dimethyl Fumarate |
|---|---|---|
| Active Ingredient | Yes | Yes |
| FDA Approval | Yes | Yes |
| Cost | High | Lower (80-85% less) |
| Effectiveness | Same | Same |
| Safety | Same | Same |
The example of dimethyl fumarate demonstrates how a drug’s price can drop significantly when it becomes a generic version. This helps more patients access the treatment they need at a lower cost.
Benefits and Side Effects of Fumarate
Main Benefits
Dimethyl fumarate helps treat multiple sclerosis and psoriasis. Doctors choose this drug because it controls swelling and protects cells. The drug alters the level of glutathione in the body, producing more heme oxygenase-1, which combats swelling. It also alters histone deacetylase in brain cells, activating Nrf2 and reducing swelling. Dimethyl fumarate slows aerobic glycolysis in immune cells, reducing the activity of these cells during disease. Studies have shown that the drug can reduce the number of lesions in patients with relapsing-remitting multiple sclerosis. Patients taking dimethyl fumarate experience fewer relapses and feel better for many years.
