Effective use of topical amitriptyline hydrochloride 2.5% and ketamine hydrochloride 0.5% for analgesia in refractory proctodynia.
Idiopathic proctodynia, an enigmatic pain syndrome affecting the perianal region, can be persistent, relatively refractory to treatment, and associated with considerable psychological distress. The authors present the case of a patient with a long history of severe proctodynia that had been resistant to a range of topical and systemic treatments. With the use of topical amitriptyline hydrochloride 2.5% and ketamine hydrochloride 0.5% cream, the patient's pain resolved rapidly, leading to a substantially improved quality of life.
