Pregabalin is a prescription medication used in the treatment of neuropathic pain, epilepsy, generalized anxiety, and depression, among other health problems. Now, new research published in the British newspaper The Sunday Times has set off all the alarms in Europe by linking its use to almost 3,400 deaths in the last five years.
This drug, which works by mimicking gamma-aminobutyric acid (GABA) – the main inhibitory neurotransmitter in the mammalian nervous system – has been administered to millions of people to date, and is now under scrutiny for its possible adverse effects and its potential to generate addiction and abuse of this substance.
