About this study

Vulvodynia (Vd) is chronic functional vulvar pain, with prevalence of 3-16% and unclear etiopathology. Although Vd significantly deteriorates quality of life, the problem is marginalized, no pharmacologic treatment standards exist. Naltrexone hydrochloride is a specific opioid antagonist with slight agonist activity. There is growing body of evidence supporting the effectiveness of low-dose naltrexone (LDN) in different types of chronic pain. The main goal of this trial is to test the effect of LDN on pain perception and quality of life in women with different types of Vd. Half of the study population receives LDN and the remaining patients take placebo, according to randomization list. This RTC is quadruplet blinded.
