Mechanism

Lyrica, a compound with both analgesic and anticonvulsant properties, was developed by Pfizer as a more potent successor to Neurontin. The exact mechanism of action has not been fully known but according to the preclinical findings, it helps to reduce the abnormal neuronal excitability by reducing neurotransmitter release.

Apparently, it binds to an a-2-d site that is an auxiliary subunit of voltage-gated calcium channels in CNS tissues and reduces neuronal excitability and seizures. In fact, it functions mechanistically to reduce pain.

It’s believed that this anti-seizure drug binds to a part of the nerves and reduces the nerves’ ability to send pain messages to each other; it slows down impulses in the brain that cause seizures and also has a noticeable effect on the chemicals in the brain that sends pain signals across the nervous system.

Global Market

After the FDA approval of Lyrica in 1990, Pfizer brought it to market as a follow-up brand to gabapentin (Neurontin). The company has also engaged in extensive direct-to-consumer advertising campaigns since 2008 so that to promote its branded product Lyrica for fibromyalgia and diabetic nerve pain indications.

The value of the Global painful diabetic neuropathy drugs (PDN) market accounted for US$ 4,811.8 Mn in 2017 and it’s projected to attain a value of US$ 8,962.0 Mn by 2026 at a CAGR of 6.6% during the next years. The ever-growing pool of geriatric population with diabetes is the primary driver of the market growth. Availability of approved drugs and the presence of an extensive diabetic patient pool are the other drives that contributed to the overall market growth.

There are only four drugs currently approved for the management of PDN that are Lyrica, Cymbalta, Nucynta, and Qutenza; so there is a huge opportunity for new and emerging market players and Lyrica supplier with potential pipeline portfolio. Among these marketed products, Lyrica accounted for a maximum market share in 2017 and will continue the similar trend through 2026.

With diabetes changing to a global concern, the PDN drugs market comprises a worldwide outreach. In 2017, North America dominated the market and is expected to maintain its position throughout 2018-2026. Due to the growing awareness of PDN and the rise in healthcare expenditure, Asia Pacific exhibited the fastest CAGR during the mentioned period. In the below figure, the sales for Lyrica and Pregabalin generics in the seven major markets (US, 5EU, and Japan) and India and China are shown during 2012-2022.

Sales volume by Lyrica sellers worldwide -2012-2022

It’s expected that sales of Lyrica and Pregabalin generics decrease from $121.2m in 2012 to $83.5m in 2022 at a negative compound annual growth rate (CAGR) of 3.7%. A major driver of Lyrica and Pregabalin generics sales during 2012-2022 is Pfizer’s historical strength in marketing.

The patent will expire in the US in 2018 and it was expired in the EU in 2013; Entry of newer and more efficacious anti-epileptic drugs (AEDs) into the market is a major barrier to Lyrica and Pregabalin generics sales over this period.
