Axsain contains capsaicin USP, in a patented emollient base containing benzyl alcohol, cetyl alcohol, glyceryl stearate, isopropyl myristate, lidocaine hydrochloride, PEG-100 stearate, purified water; sorbitol solution and white petrolatum.
Axsain is indicated for the temporary relief of neuralgia pain,
including painful diabetic neuropathy (PDN) and postherpetic neuralgia (PHN), when used under the supervision of a physician. Axsain is particularly useful as adjunctive therapy for PDN and PHN patients experiencing incomplete pain relief despite taking oral antiepileptics or tricyclic antidepressants.

Capsaicin instillation for postoperative pain following total knee arthroplasty: a preliminary report of a randomized, double-blind, parallel-group, placebo-controlled, multicentre trial. [2011.12.01]
BACKGROUND: Pain following total knee arthroplasty (TKA) interferes with rehabilitation. Capsaicin applied in high concentration to nociceptors can cause relatively selective C-fibre desensitization for a period of weeks to months. Resultant long-lasting analgesia might facilitate rehabilitation. OBJECTIVE: The objective of this study was to determine if direct instillation of a high-concentration capsaicin preparation into the wound following TKA would provide pain relief, improve physical functioning and rehabilitation, and reduce opioid requirements... CONCLUSION: Despite having higher BMIs, patients in the capsaicin group achieved comparable or better pain scores with significantly less opioid use in the first 3 postoperative days. They also had less pruritus, which may have been a consequence of the opioid-sparing effect. The effects of capsaicin with respect to function, however, appeared to be longer lasting, with improved active ROM reported at 14 days.
A randomized, double-blind, parallel trial comparing capsaicin nasal spray with placebo in subjects with a significant component of nonallergic rhinitis. [2011.08]
OBJECTIVE: To investigate the efficacy and safety of ICX72 or Sinus Buster, a proprietary homeopathic preparation of Capsicum annum and Eucalyptol, versus placebo administered continuously over 2 weeks in subjects with a significant component of nonallergic rhinitis (NAR)... CONCLUSION: This is the first controlled trial demonstrating intranasal capsaicin, when used continuously over 2 weeks, rapidly and safely improves symptoms in rhinitis subjects with a significant NAR component.

Clinical Trials Related to Axsain (Capsaicin / Lidocaine)
Acute Response Capsaicin Flare Study [Recruiting]
Prior to administering PF-04427429 to patients we wish to increase the understanding of
functional effects associated with calcitonin gene related peptide (CGRP) pathways. This
study will examine whether it is possible for a single dose of PF-04427429 to acutely
attenuate a capsaicin induced flare response.
Method of Pre-treatment for Application of QUTENZA Capsaicin 8% Patch [Recruiting]
The Summary of product characteristics (SmPC) for QUTENZA advises that topical anaesthetic
is applied prior to the application of QUTENZA. This is a multi-center, randomized,
assessor-blinded study which will investigate the use of an oral analgesic as an alternative
form of pre-treatment for QUTENZA.
Trial to Evaluate the Efficacy of Topical Capsaicin to Reduce Pain and Improve Health-related Quality of Life in Adults With Chronic Myofascial Neck Pain [Not yet recruiting]
Chronic neck pain is a common condition that can negatively impact quality of life.
Substance P is one of the chemicals in the body that can transmit pain signals from
overloaded neck muscles to the brain. Topical capsaicin blocks the action of Substance P by
releasing, and subsequently depleting the body's store of Substance P in the nerves.
Topical capsaicin has been reported to be an effective therapy for a number of persistent
pain conditions including diabetic neuropathy, post-herpetic neuralgia, osteoarthritis,
rheumatoid arthritis, and post-mastectomy pain. This study will evaluate the efficacy of
topical capsaicin to reduce pain and improve health-related quality of life in adults with
chronic muscular neck pain.
A Study to Evaluate the Efficacy and Safety of a Single Application of QUTENZA Compared to That of Placebo in Reducing Pain Intensity in Subjects With Painful Diabetic Peripheral Neuropathy (PDPN) [Recruiting]
The purpose of the study is to assess how well a single treatment of QUTENZA reduces pain
from damaged nerves (neuropathic pain) caused by diabetes and how safe QUTENZA is when
compared to using a placebo.
Efficacy and Safety Study of Topical Capsaicin in Painful Diabetic Neuropathy [Recruiting]
Painful diabetic neuropathy is the most common cause of neuropathic pain. 0. 075% topical
capsaicin has been used to treat the pain, but there is no data in lower concentration. This
is the efficacy and safety of 0. 025% topical capsaicin in treatment of painful diabetic
