As of 2015, the names of some common prescription sleeping pills include Ambien, Sonata, Lunesta and Silenor, states WebMB. Doctors prescribe the drugs to treat insomnia and other sleeping disorders.
Ambien contains the drug zolpidem, which helps insomniacs get to sleep quickly and stay asleep longer, notes WebMD. Zalephon, the active ingredient in Sonata, stays active in the body for a short period of time, reducing drowsiness in the morning. Lunesta contains eszopiclone, which is fast-acting and can cause grogginess in the morning, and Silenor, which contains doxepine, blocks histamine receptors to help people who have trouble staying asleep.
Ambien, Sonata and Lunesta can lead to drug dependence, warns Mayo Clinic. People should seek medical advice before taking any drug to treat insomnia.
