Zolpidem (sold under the brand names Ambien, Stilnox, and Sublinox) is a prescription medication used for the treatment of insomnia, as well as some brain disorders. It is a short-acting nonbenzodiazepine hypnotic of the imidazopyridine class that potentiates gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter, by binding to GABA_A receptors at the same location as benzodiazepines. It works quickly (usually within 15 minutes) and has a short half-life (two to three hours).

Zolpidem has not adequately demonstrated effectiveness in maintaining sleep (unless delivered in a controlled-release form); however, it is effective in initiating sleep. Its hypnotic effects are similar to those of the benzodiazepine class of drugs, but it is molecularly distinct from the classical benzodiazepine molecule and is classified as an imidazopyridine. Flumazenil, a benzodiazepine receptor antagonist, which is used for benzodiazepine overdose, can also reverse zolpidem's sedative/hypnotic and memory-impairing effects.

Patton Oswalt (born January 27, 1969) is an American stand-up comedian, writer, actor and voice actor known for roles such as Spencer Olchin in the popular sitcom The King of Queens, and voicing Remy from the film Ratatouille and Thrasher from the Cartoon Network original series Robotomy.

Oswalt was born January 17, 1969 in Portsmouth, Virginia, to Carla and Larry J. Oswalt, a career United States Marine Corps officer. He was named after George S. Patton.

He is a 1987 graduate of Broad Run High School in Ashburn, Virginia and later attended the College of William and Mary, where he majored in English and was initiated into the Alpha Theta Chapter of the Phi Kappa Tau Fraternity.^{[citation needed]}

Oswalt first began performing standup comedy in the late 1980s or early 1990s, by his own reckoning. After writing for MADtv and starring in his own 1996 comedy special for HBO, he went on to garner notable roles in films and television shows. His most prominent and long-running role was as Spence Olchin on The King of Queens. His first starring film role was as the voice of Remy, the lead character in the 2007 Pixar film Ratatouille. He has also appeared in smaller roles in such films as Magnolia and Madagascar: Escape 2 Africa. He lent his voice as in the video game Grand Theft Auto: San Andreas as a caller on the WTCR show "The Tight End Zone", and was the voice of a caller on "Chatterbox" on LCFR in the game Grand Theft Auto: Liberty City Stories. He was also the voice of a reporter on "New World Order", a radio show on VCPR in Grand Theft Auto: Vice City Stories. He supposedly lent his voice as Randall Tugman in the zombie game Dead Rising 2, although he denies this. The character Randall Tugman is credited to have been voiced by John Murphy.

George Lopez (born April 23, 1961) is an American comedian, actor, and talk show host. He is mostly known for starring in his self-produced ABC sitcom George Lopez. His stand-up comedy examines race and ethnic relations, including the Mexican American culture. He was the host of the late-night talk show Lopez Tonight on TBS until its cancellation on August 12, 2011.

Lopez was born on April 23, 1961 in Mission Hills, California. He was deserted by his father when he was two months old and by his mother when he was 10 years old, but was raised by his maternal grandmother, Benita Gutierrez, a factory worker, and step-grandfather, Refugio Gutierrez, a construction worker.

In 1999, Lopez hosted a major morning radio show for Clear Channel Communications in Los Angeles. He was the first Latino to have headlined the keystone morning radio slot on an English-language station in LA—the nation’s top radio market.

In 2000, after several years of performing stand-up comedy, Lopez was approached by actress Sandra Bullock for Lopez to produce and star in a comedy. Bullock was concerned about the lack of Hispanic-oriented sitcoms on American television and pushed to get a sitcom on television that starred Hispanics without being exclusively about the Hispanic American community. Long criticized by Hispanic American groups for lack of Latinos on their television shows, ABC quickly picked up the television series. In 2002, Lopez became one of the few Latinos to star in a television comedy series, following in the footsteps of Desi Arnaz, Freddie Prinze, and John Leguizamo. George Lopez is an American situation comedy that originally aired on ABC from 2002–2007. Lopez is the co-creator, writer, producer, and star of the show.
