Who are the nonresponders to standard treatment with tricyclic antidepressant agents for cyclic vomiting syndrome in adults?
Product Description:
RESULTS: The nonresponders were receiving TCAs at an average dose of 90 mg/day compared to a mean dose of 85 mg/day in responders. Compared with the responders, the nonresponders were significantly more likely to have a history of migraine (P < 0.05); co-existing psychological disorders (P < 0.05); chronic marijuana use (P < 0.05) and reliance on narcotics for pain control between cyclic vomiting syndrome episodes (P < 0.05). CONCLUSIONS:(1) Nonresponse to standard therapy in adult cyclic vomiting syndrome patients occurs in approximately 13% and is not explained by under dosing with TCA therapy. (2) The main risk factors for nonresponse are: co-existing migraine headache, psychiatric disorder, chronic narcotic and marijuana use, which should be addressed aggressively when symptom exacerbations continue during attempts to induce remission in cyclic vomiting syndrome with high-dose TCA therapy.
