1620s, "inducing sleep," originally used of drugs, from French hypnotique (16c.) "inclined to sleep, soporific," from Late Latin hypnoticus, from Greek hypnotikos "inclined to sleep, putting to sleep, sleepy," from hypnoun "put to sleep," from hypnos "sleep" (see somnolence). Modern sense of "pertaining to an induced trance" first recorded in English 1843, along with hypnotist, hypnotize, both coined by Dr. James Braid. Related: Hypnotical; hypnotically.
hypnotic hyp·not·ic (hĭp-nŏt'ĭk)
Of or relating to hypnotism or hypnosis.
Inducing or tending to induce sleep; soporific.
chemical substance used to reduce tension and anxiety and induce calm (sedative effect) or to induce sleep (hypnotic effect). Most such drugs exert a quieting or calming effect at low doses and a sleep-inducing effect in larger doses. Sedative-hypnotic drugs tend to depress the central nervous system. Since these actions can be obtained with other drugs, such as opiates, the distinctive characteristic of sedative-hypnotics is their selective ability to achieve their effects without affecting mood or reducing sensitivity to pain.
