Pharmacology

Pregabalin is a structural analogue of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA), but it does not act directly on GABAA, GABAB, or benzodiazepine receptors. Instead, it binds with high affinity to the alpha2-delta site, an auxiliary subunit of voltage-gated calcium channels in central nervous system tissue. Pregabalin's exact mechanism of action is not yet fully understood, but animal studies suggest that this binding to the alpha2-delta subunit may contribute to its pain-relieving and antiseizure effects.

Pregnancy & Breastfeeding

Pregnancy & Breastfeeding

There haven't been enough well-controlled studies of pregabalin in pregnant women to establish its safety, so pregnant women should be made aware of the possible risk to the baby. Trace amounts of pregabalin have also been found in the breast milk of nursing mothers, and because of a possible risk of tumour formation, breastfeeding is not advised while being treated with pregabalin.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.
