No, Lyrica it's stronger something like gabapentin v2, it's stronger and the high it's similar but obviously more intense with Lyrica, excuse me but my English it's a little bad
Not sure about pricing.
This class of drugs are known as gabapentinoids and have similar mechanisms of action.
Gabapentin (generally) is absorbed at around 30% whereas pregabalin is pretty much used completely if I am not mistaken.
Big difference in dose to reach the same state.
I would personally opine that pregabalin is 5-8 times as strong in effects at same doses.
If one is not careful and doses too much (pregabalin) there is a high chance of some physical mishaps that may be painful.
