Outcome:
1 paper was identified that was relevant to the clinical question and there was 1 Cochrane review. Salbutamol has never been studied.

Terbutaline inhalation for alleviation of severe pain in essential dysmenorrhea. Kullander S 1981 Scandinavica Not in emergency department setting Kullander S and Svanberg L examined the effect of terbutaline spray inhalations in 14 women with severe dysmenorrhoea. A significant relief was noted in association with an increased menstrual blood loss. The side effects were few. Terbutaline inhibited the myometrial activity, increased the blood flow, and relieved the pain.
The Study was conducted in 1981, thus not a recent one. It was not performed in a modern emergency department therefore can not be generalised to patients presenting in emergency departments.
Author Commentary:
There is evidence that beta-adrenoreceptor agonists reduce uterine tonicity, but insufficient evidence that this translates to the reduction of pain. The study available on inhaled beta 2 agonist is too small to make an adequate assessment of their utility. The limited evidence there shows that this is potential treatment worthy of further study.
Bottom Line:
There is no evidence currently to suggest that Salbutamol as beta-adrenoreceptor agonists are effective as pain relief for dysmenorrhoea and further study is required. However there are studies on other beta adrenoreceptor agonist which shows improvement in patients symptoms.
