An agent that produces narcosis, in moderate doses it dulls the senses, relieves pain and induces sleep; in excessive dose it cause stupor, coma, convulsions and death.
Any opioid-derived drug, natural or synthetic, that relieves pain or alters mood. May cause addiction.
A drug or agent which in moderate doses depresses the central nervous system, relieving pain and producing sleep but in large doses, produces unconsciousness, stupor, coma and possibly death.
Causes drowsiness or stupor and relieves pain.
Causing sleep or coma.
A substance that depresses central nervous system function, bringing sleep and lessening pain. By definition, narcotics can be toxic in excess.
A substance that produces insensibility or stupor, combined with a sense of well-being.
Agent that induces sleep; intoxicating or poisonous in large doses.
A drug—made from opium or made artificially—that is used to relieve pain. It changes one’s sense of pain and may cause a heightened sense of well-being, mental confusion, mood changes, and deep sleep. Repeated and long-term use of a narcotic may result in physical and psychological addiction.
A drug that dulls the senses. Used to induce sleep or as a painkiller.
Produces stimulation or excitement followed by insensibility or stupor.
A drug derived from opium or opiumlike compounds that are analgesics, also producing significant alterations in mood and behavior. Addiction is possible, followed by a withdrawal syndrome upon the sudden, prolonged abstinence from the drug.
Drugs that induce sedation in small amounts, coma and death in large amounts, insensitivity to pain, and feelings of euphoria. There are four legal classes: (1) class A which include opium and its derivatives, coca leaves—their alkaloids and derivative meperidine, methadone, and other synthetic opiates; (2) class B, which include drugs having relatively little addicting potential, including papaverine and codeine; (3) class M which include those drugs that are especially exempt and may be prescribed by a physician, with-out filling out a narcotics order. Drugs in this class are considered non-addicting. (4) Class X, which includes drugs containing a prescribed minimum amount of narcotic and are non-addicting as prescribed.
A pain-relieving drug which makes someone sleep or become unconscious.
An agent that relieves pain and induces sleep. Narcotics sometimes produce visions and offer the potential for abuse.
Drugs used to relieve pain and induce sleep (morphine, heroin, etc.). Usually addictive.
Drug, derived from opium or produced synthetically, that relieves pain, induces euphoria and other mood changes, decreases respiration and peristalsis, constricts the pupils, and produces sleep. Narcotic drugs are addictive, producing drug addiction after repeated use. Narcotic drugs used for pain relief include morphine, meperidine (Demerol), and codeine; heroin and other narcotics are common street drugs.
A drug that induces stupor and insensibility and relieves pain. The term is used particularly for morphine and other derivatives of opium but is also applied to other drugs that depress brain function (e.g. general anesthetics and hypnotics). In legal terms a narcotic is any addictive drug subject to illegal use. Narcotics (i.e. morphine and morphinelike drugs) have been largely replaced as sleeping drugs because of their ability to cause dependence and tolerance; they are still used for relief of severe pain.
A substance that induces stupor and insensibility and relieves pain.
Analgesics (painkillers); sleep-inducing drugs. Narcotics act on the central nervous system to relieve pain. No matter what the reason for their use, any narcotics used for a long time can potentially cause physical and psychological dependence. Physical dependence can cause symptoms of withdrawal when the narcotic is stopped.
Substances that induce stupor and eventually unconsciousness. Used in the relief of severe pain, people can become first tolerant of them so requiring larger doses and then dependent.
Narcotics are powerful painkillers. The narcotic analgesics, often referred to as opioids, also produce pleasurable feelings (euphoria), induce sleep, and depress breathing. Heroin is the most rapidly acting opiate.
Any depressant drug made from or chemically similar to opium.
Narcotics, also known as opiate derivatives or substances resembling opium, manifest as powerful analgesics that have the ability to impact an individual’s emotional state and conduct. Prolonged consumption of these medications can engender both reliance and tolerance within an individual’s system.
Generating or connected to narcosis; informally, a drug that induces narcosis.
