Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To study that 0.075% capsaicin lotion is safe, well tolerated and provide significant pain relief in patients with PDN compared with placebo lotion as a randomized, double- Blind, crossover, placebo-controlled trial

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Neuropathy is one of the most common complications in both type 1 and type 2 diabetes mellitus. The most common symptom is a symmetrical, chronic, axonal, length-dependent sensorimotor polyneuropathy.

Topical capsaicin formulations are widely used to manage pain. Low-concentration creams, lotions, and patches intended for daily skin application have been available in most countries since the early 1980s.

We study 0.075% capsaicin lotion is safe, well tolerated and provide significant pain relief in patients with PDN compared with placebo lotion as a randomized, double- Blind, crossover, placebo-controlled trial for 20 weeks throughout the study in 42 participants. All participants are provided both 0.075% capsaicin lotion and placebo lotion. Each agent will be applied for 8 weeks then stop for 4 weeks, after that another agent will be used for 8 weeks. We keep following up all of them by calling and appointment to get information in effectiveness and adverse effect at 0,2,4,8,12,14,16,20 week, respectively.
