Neuropathic Pain – US Drug Forecast and Market Analysis to 2022

Neuropathic pain (NP) is defined as a disorder of the sensorimotor system and is distinctly different from nociceptive pain, which is a consequence of trauma, injury, or inflammation. The main difference between neuropathic and nociceptive pain is the absence of a continuous nociceptive input in neuropathic pain. Although the term neuropathic pain is used to describe a wide range of pain syndromes with varying etiologies, this report focuses on 3 distinct forms of NP: Painful diabetic neuropathy, Postherpetic neuralgia and trigeminal neuralgia. The main classes of drugs used to treat these three neuropathic pain indications include anticonvulsants, antidepressants, opioids and topical treatments. However, despite the availability of multiple pain medications only 50% of patients respond to any given drug and there are numerous the side effects associated particularly with systemically administered drugs, that reduce their tolerability.

The obesity epidemic in the US, which will lead to an increased prevalence of PDN, and the launch and uptake of seven pipeline drugs, will also be key growth drivers. Among these pipeline drugs, DS-5565, which is in development for PDN, is anticipated to offer an improvement upon Lyrica’s efficacy and safety, and as such, it is expected to be the market-leading brand-name drug at the end of the forecast period, with sales of $389m in 2022.
