Randomized Controlled Trial
Predictors of Response in Patients with Post-herpetic Neuralgia and HIV-associated Neuropathy Treated with the 8% Capsaicin Patch (Qutenza®).
Qutenza is a high-dose capsaicin patch used to relieve neuropathic pain from postherpetic neuralgia (PHN) and HIV-associated neuropathy (HIV-AN). In clinical studies, some patients had a dramatic response to the capsaicin patch. Our objective was to determine the baseline characteristics of patients who best benefit from capsaicin patch treatment. ⋯ We identified subpopulations of PHN and HIV-AN patients likely to benefit from the capsaicin patch.
