What is AMBIEN CR?
AMBIEN CR is the latest formulation of the sleep aid AMBIENĀ® (zolpidem tartrate) CIV tablets. AMBIEN CR is the only prescription, 2-layer sleep aid for the treatment of insomnia. The first layer dissolves quickly, to help you get to sleep fast. Then, the second layer dissolves slowly, to help you stay asleep, so you wake up less frequently and fall back to sleep faster. In clinical studies AMBIEN CR was proven effective for up to 7 hours and can be taken for as long as your physician recommends.
