Background: Topical capsaicin therapy may be of benefit in providing pain relief in patients with peripheral neuropathy. Objectives: To investigate the efficacy and safety of 0.625% (50 µg/cm2 ) and 1.25% (100 µg/cm2 ) capsaicin patches (CPs) compared to conventional 0.075% capsaicin cream or placebo patches in patients suffering from peripheral neuropathy. Study Design: Early Phase II, multi-center, randomized, semi-double-blind, and placebocontrolled clinical trial. Setting: Two medical college teaching hospitals. Methods: Sixty patients were randomized to the 0.625% CP, 1.25% CP, placebo-controlled patch, or 0.075% capsaicin cream. The primary efficacy endpoint was the mean difference in the change of daily numerical rating scale (NRS) pain score. Secondary endpoints included values for the Daily Sleep Interference Scale, the percentage of patients achieving a ≥ 30% or ≥ 50% reduction in pain, and data for Global Impression Change (GIC) and EQ-5D. Results: Patients treated with the 0.625% CP and 0.075% capsaicin cream showed statistically significant improvements in pain after 6-weeks of test drug application. Daily sleep disorder scores were improved only for those patients applying the 0.075% capsaicin cream. For patient-derived GIC scores, the majority (11 of 12) of patients in the 0.625% CP group reported that their pain was improved. For the safety evaluation, 2 severe adverse events were reported for the 0.075% capsaicin cream group only. Repetitive patch application was related to minor skin problems such as a burning sensation, erythema, pruritus, and vesicles in 28 patients (46.67%). Limitations: The small sample size and relatively high dropout rates. Conclusion: Our data indicate that the 0.625% CP may prove to be an effective and safe alternative with which to treat patients with peripheral neuropathy and could replace the high concentration (8%) CP. Further studies are now needed to definitively establish efficacy. Key words: Capsaicin, patch, CP, topical capsaicin, neuropathic pain, peripheral neuropathic pain, PNP, high concentration CP

ABSTRACT Introduction Dyspepsia is a clinical problem of considerable magnitude for the healthcare system due to the high prevalence and chronic and recurrent nature of symptoms. Earlier dyspepsia was referred to as a heterogeneous group of symptoms in the upper abdomen and retrosternal which are related to ingestion of meals and include heartburn, regurgitation, epigastric pain, epigastric burning, postprandial fullness/distension, early satiety, bloating, belching, anorexia, nausea, and vomiting. This has prompted the search for newer agents with equal efficacy but lower side effect potential such as levosulpiride and itopride. Aim and objectives To evaluate and compare the efficacy of the newer drugs like levosulpiride and itopride in functional dyspepsia. Observations and results The most common presenting symptoms in the present study were epigastric fullness (81%), upper abdominal pain (55%), early satiety (52%), and epigastric burning (45%). Less common symptoms were bloating (27%), belching (11%), heartburn (10%), and nausea (8%). Conclusion Drugs, itopride and levosulpiride, were equally effective in ameliorating different symptoms of functional dyspepsia at the end of 4 weeks of treatment. There was a significant reduction in mean global symptom score (GSS) and mean duration score and mean score of severity in follow-up visits at the 2nd and 4th week from the day of presentation (p value < 0.05).
