Skeletal muscle relaxants for the treatment of myofascial pelvic pain and high tone pelvic floor disorders.

PURPOSE OF REVIEW: Chronic pelvic main is a complex process that includes many causes. In gynecology, the treatment of myofascial pelvic pain and high tone pelvic floor disorders can be managed with skeletal muscle relaxants for select clinical indications. A review of skeletal muscle relaxants will be included for gynecologic indications. RECENT FINDINGS: There are limited studies on vaginal skeletal muscle relaxants, but there can be oral forms used for chronic myofascial pelvic pain. They function as antispastic, antispasmodic, and combination of the two modes of action. Diazepam is the most studied for myofascial pelvic pain in both oral and vaginal formulations. Its use can be combined with multimodal management to optimize outcomes. Other medications have limitations due to dependency and limited studies that demonstrate improvement in pain scales. SUMMARY: Skeletal muscle relaxants have limited high quality studies for chronic myofascial pelvic pain. Their use can be combined with multimodal options to improve clinical outcomes. Additional studies are needed for vaginal preparations and evaluation of safety and clinical efficacy for patient reported outcomes measures in patients living with chronic myofascial pelvic pain.
