The main cause of dysmenorrhea is the rise in prostaglandins, so prostaglandin synthase inhibitors are preferred for the treatment of dysmenorrhea. Prostaglandin synthase inhibitors reduce or eliminate dysmenorrhea by inhibiting the activity of prostaglandin synthase, resulting in a decrease in prostaglandin synthesis and preventing uterine contractions and spasms. Prostaglandin synthase inhibitors are more commonly used as ibuprofen and ketoprofen. Usually after taking the medication, the symptoms of dysmenorrhea are significantly reduced. For patients with more severe dysmenorrhea, it is recommended to take oral contraceptive drugs, which reduce the amount of prostaglandins in the menstrual blood by inhibiting ovulation. For this condition, you can choose Daing-35, Eusemin, Eusypt, Mafulon, etc.
