Opioid overdoseAn opioid overdose is toxicity due to excessive consumption of opioids, such as morphine, codeine, heroin, fentanyl, tramadol, and methadone. This preventable pathology can be fatal if it leads to respiratory depression, a lethal condition that can cause hypoxia from slow and shallow breathing. Other symptoms include small pupils (with the exception of pethidine, where there may be dilated pupils), and unconsciousness, however its onset can depend on the method of ingestion, the dosage and individual risk factors.
PapaverinePapaverine (Latin papaver, "poppy") is an opium alkaloid antispasmodic drug, used primarily in the treatment of visceral spasms and vasospasms (especially those involving the intestines, heart, or brain), occasionally in the treatment of erectile dysfunction and acute mesenteric ischemia. While it is found in the opium poppy, papaverine differs in both structure and pharmacological action from the analgesic morphine and its derivatives (such as codeine). Papaverine was discovered in 1848 by Georg Merck (1825–1873).
Supervised injection siteSupervised injection sites (SIS) are medically supervised facilities designed to provide a hygienic environment in which people are able to consume illicit recreational drugs intravenously and prevent deaths due to drug overdoses. The legality of such a facility is dependent by location and political jurisdiction. Supervised injection sites are part of a harm reduction approach towards drug problems. The facilities provide sterile injection equipment, information about drugs and basic health care, treatment referrals, access to medical staff, and, at some facilities, counseling.
ProdrugA prodrug is a pharmacologically inactive medication or compound that, after intake, is metabolized (i.e., converted within the body) into a pharmacologically active drug. Instead of administering a drug directly, a corresponding prodrug can be used to improve how the drug is absorbed, distributed, metabolized, and excreted (ADME). Prodrugs are often designed to improve bioavailability when a drug itself is poorly absorbed from the gastrointestinal tract.
Drug policyA drug policy is the policy regarding the control and regulation of psychoactive substances (commonly referred to as drugs), particularly those that are addictive or cause physical and mental dependence. While drug policies are generally implemented by governments, entities at all levels (from international organisations, national or local government, administrations, or private places) may have specific policies related to drugs.
NoscapineNoscapine (also known as Narcotine, Nectodon, Nospen, Anarcotine and (archaic) Opiane) is a benzylisoquinoline alkaloid, of the phthalideisoquinoline structural subgroup, which has been isolated from numerous species of the family Papaveraceae (poppy family). It lacks significant hypnotic, euphoric, or analgesic effects affording it with very low addictive potential. This agent is primarily used for its antitussive (cough-suppressing) effects. Noscapine is often used as an antitussive medication.
Buprenorphine/naloxoneBuprenorphine/naloxone, sold under the brand name Suboxone among others, is a fixed-dose combination medication that includes buprenorphine and naloxone. It is used to treat opioid use disorder, and reduces the mortality of opioid use disorder by 50% (by reducing the risk of overdose on full-agonist opioids such as heroin or fentanyl). It relieves cravings to use and withdrawal symptoms. Buprenorphine/naloxone is available for use in two different forms, under the tongue or in the cheek.
