No, there aren't any new rules about patent extension. The same 17 year window still applies but it seems that the French have found a new way to keep their market share even when the patent on Ambien expires. Their secret? Ambien Extended Patent...er... I mean Controlled Release. Ambien CR is merely a way for French pharmaceutical giant Sonofi-Aventis to keep market share after the patent on Ambien expires. Ambien CR is the same medicine as Ambien, merely formulated to change the pharmacokinetic profile. Additionally the dosage of Ambien in Ambien CR has been increased. Regular Ambien is sold in 5 & 10 mg pills. The new Ambien CR is sold in 6.25 and 12.5 mg pills.
If Ambien is working for you there is no need to switch to the controlled release formula. In fact, when Ambien comes off patent it will result in significant reductions in price for consumers. Generic zolpidem tartrate will be just as effective as Ambien.
