![]() Logistic regression was used to identify predictors of response and Complete Response, and subgroups of patients who respond best to the capsaicin patch.īaseline pain intensity score (BPIS)≤4 was a predictor of Sustained and Complete Response in PHN and HIV-AN patients absence of allodynia and presence of hypoesthesia, and a McGill Pain Questionnaire (MPQ) sensory score <22 were predictors of Sustained Response in PHN patients female sex was a predictor of Sustained and Complete Response in HIV-AN patients. Sustained response was defined as>50% decrease in the mean pain intensity from baseline to weeks 2 to 12, and Complete Response as an average pain intensity score≤1 during weeks 2 to 12. We conducted a meta-analysis of 6 completed randomized and controlled Qutenza studies by pooling individual patient data. Our objective was to determine the baseline characteristics of patients who best benefit from capsaicin patch treatment. In clinical studies, some patients had a dramatic response to the capsaicin patch. ![]() Qutenza is a high-dose capsaicin patch used to relieve neuropathic pain from postherpetic neuralgia (PHN) and HIV-associated neuropathy (HIV-AN).
