The objectives of this study are to determine efficacy and safety of 0. 75% topical capsaicin nanoparticle preparation versus placebo in patient with painful diabetic neuropathy.

Clinical Details

Official title: Study of Topical Preparation of Capsaicin Nanoparticle in Patient With Painful Diabetic Neuropathy

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Pain relief from pain score reduction, using visual analog scale (VAS)

Detailed description: Painful diabetic neuropathy is the most common cause of neuropathic pain. 0. 075% topical capsaicin has been used to treat the pain. Because of high concentration, conventional capsaicin topical preparation causing burning sensation and required several time of applications per day. The nanoparticle of capsaicin topical preparation was developed with expectation of remaining efficacy, minimizing burning sensation and improving convenience of use.


Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.
