Components, Properties, and Specifications of Dimethyl Fumarate (富马酸二甲酯)

For patients currently using or considering Dimethyl Fumarate (富马酸二甲酯), understanding its components, properties, and specifications is crucial for ensuring medication safety and efficacy. Dimethyl Fumarate is a drug used to treat multiple sclerosis, and its application in the medical field has seen significant progress in recent years. This article will delve into the components, physical and chemical properties, and related specifications of Dimethyl Fumarate.

Component Analysis

The main component of Dimethyl Fumarate is Dimethyl Fumarate itself, with the chemical formula C6H8O4 and a molecular weight of 144.13. It is a fumarate ester compound, scientifically named Dimethyl Fumarate, obtained through the esterification reaction of fumaric acid with methanol. The structural characteristics of this compound confer certain antioxidant properties within the body, which help reduce cellular inflammatory responses and are one of the mechanisms for its use in treating multiple sclerosis.

Physical and Chemical Properties

Dimethyl Fumarate appears as a white crystalline powder or powder, with a slight pungent odor, a melting point of 103-104°C, and a boiling point of 193°C. It is soluble in organic solvents such as ethanol, ethyl acetate, and chloroform, but insoluble in water. Additionally, it remains largely unchanged under ultraviolet light and sunlight for up to 72 hours and does not decompose when heated at 110°C for 2 hours.

Specifications

In pharmaceutical preparation, the standard specifications for Dimethyl Fumarate typically include purity, impurity content, and microbial limits. The purity is generally required to be no less than 98%, and it must comply with the relevant regulations of national pharmacopeias or international standards. Moreover, due to its application in pharmaceutical formulations, there are strict testing and evaluation procedures for the stability of the product, the release characteristics of the formulation, and biocompatibility.

Indications and Dosage

Dimethyl Fumarate is primarily used to treat relapsing forms of multiple sclerosis, a disease affecting the central nervous system. The drug alleviates symptoms by reducing inflammation in the nervous system and protecting nerve cells. The usual administration method is oral, with dosing 2 to 3 times daily, and the specific dosage should be adjusted according to the doctor's recommendation.

Q&A Cases
