It is to be expected that there will be claims against Pfizer for the losses incurred as a result of the lyrica price canada excess prescription costs to the NHS, and the loss of sales for Actavis. Warner-Lambert (part of the Pfizer group) had a second medical use patent for the use of pregabalin in the treatment of neuropathic pain. The examples in the patent specification were typical models of inflammatory pain, but the patent claimed treatment of all kinds of pain (in claim 1), and all kinds of neuropathic pain (in claim 3). (There are two main classes of neuropathic pain – central neuropathic pain and peripheral neuropathic pain). Both at first instance in the Patents Court, and on appeal at the Court of Appeal, the patent was found to be invalid for insufficiency, because the information in the patent did not make it plausible that pregabalin could be used to treat all kinds of pain.
So, You Think Your Drug Is Counterfeit—Now What?
- One of the respondents also reported that pregabalin was the first psychoactive substance she tried after alcohol, even though she did not abuse alcohol and reported no psychopathological symptoms before starting to use pregabalin.
- Good oral hygiene accompanied with a healthy diet can help keep our teeth free from decay and damage.
- FDA approved this medicine in 2004, and it is one of the most demanding and recommended solutions for pain management and seizures.
- Reports of pregabalin’s addictive potential began to appear immediately after the drug’s market launch in 2005 6, the first cases of pregabalin abuse in Europe were recorded in 2008 7, and the first pregabalin use disorders were diagnosed in 2010 8.
They aligned with the initial view of Arnold J in his interim decisions that the test is whether the alleged infringer subjectively intended to target the patent-protected market – in the present case there was no subjective intent, and therefore likewise no infringement. Since the patent was held invalid, the comments on infringement are obiter (non-binding), and the Supreme Court was divided on how infringement of Swiss form claims should be interpreted. It was unanimous however that there would have been no infringement on the facts of the present case, had the patent claims been held to be valid. However, the split makes it hard to know how UK Courts will interpret second medical use claims in future.

In Belgium, the Chemfield project was launched to develop a digital support tool to reduce the harm caused by chemsex practices 186, and in Taiwan, a medical centre dedicated exclusively to chemsex issues was established in 2017 187. Experimental studies in rats have demonstrated the ability of pregabalin to cause oxidative stress in the central nervous system, leading to neuron degeneration 139. The above mechanisms lead to brain damage, memory impairment, decreased locomotor activity, and the onset of psychosis. These effects are observed with prolonged administration of high doses of pregabalin, which is typical for recreational use 20, 140. A decrease in cognitive function has also been shown with prolonged use of pregabalin at therapeutic doses 141.
