Tapentadol helps in trigeminal neuralgia: a case report.

BACKGROUND

Trigeminal neuralgia (TN) usually affects people over 50 years old. TN-related pains are short-lived, and the disease course is characterized by exacerbations and remissions. Sometimes chronic pain develops due to central sensitization. This is the first case report on the effectiveness of tapentadol in pain control in TN.

CASE DESCRIPTION: It is an instructive case history demonstrating the high effectiveness of tapentadol in a 55-year-old Caucasian male with severe [Visual Analogue Scale (VAS) 9/10] TN-related pain and a history of ineffective treatment with antiepileptic drugs. The neuralgia had occurred twice a year for the three preceding years, and typically the TN periods lasted 2-3 weeks with complete remissions between. Previously the patient had been treated with antiepileptic drugs (e.g., carbamazepine, phenytoin, clonazepam, gabapentin, and lamotrigine). However, he found all treatments to be ineffective and accompanied by unacceptable somnolence. Thus, a prolonged-release oral tapentadol was proposed at the beginning of the next relapse. After application of tapentadol, the patient reported a significant improvement. The severity of pain declined to VAS 6/10 (2nd day) and 4/10 (3rd day), and the attacks resolved entirely on the fourth day of treatment. He reported no side effects. The drug was discontinued after 14 days.

CONCLUSIONS

Despite pain chronification, tapentadol was efficient and well tolerated in TN. Further research is needed to reveal tapentadol's efficacy in neuralgias.
