Description

FIELD[0001]The present invention relates to use of a carbamate compound of the following Formula 1 for the purpose of preventing the occurrence of headaches including migraine, by administering a pharmaceutical composition comprising said carbamate compound:[0002]wherein,[0003]R1, R2, A1 and A2 are as defined herein.BACKGROUND[0004]Migraine is a common disease with a worldwide prevalence rate of 8 to 18%. It occurs more frequently in women than in men, and can occur in both children and adults. Symptoms of migraine include not only headaches but also accompanying symptoms such as nausea, vomiting, photosensitivity, hypersensitivity to sound and hypersensitivity to odor, which are obstacles to physical activity. Such migraine-related disorders cause socio-economic losses worldwide and seriously hamper the quality of life (Krymchantowski et al., New and emerging prophylactic agents for migraine, CNS Drugs, 2002; Jackson et al., A comparative effectiveness meta-analysis of drugs for th...

AI Technical Summary

Benefits of technology

The medications and pharmaceutical compositions in this patent can prevent headaches, specifically the chronic ones associated with CSD and migraines. They do not affect the normal blood flow or communication between brain cells.

Problems solved by technology

Such migraine-related disorders cause socio-economic losses worldwide and seriously hamper the quality of life (Krymchantowski et al., New and emerging prophylactic agents for migraine, CNS Drugs, 2002; Jackson et al., A comparative effectiveness meta-analysis of drugs for the prophylaxis of migraine headaches, PLOS ONE, 2015).

Although the pathological mechanism of migraine has not been fully understood until now, it is believed that the electrochemical imbalance in the brain due to the excitability of excessive cranial nerve caused by various environmental and intrinsic factors will act as a cause of migraine.

Valproate has been used to prevent migraine, but it is known to have side effects such as liver damage and congenital malformations.

A variety of drugs have been used for the treatment or prevention of migraine, but there are still limitations in their use due to the lack of satisfactory level of drug response or side effects.
