コデイン

Also known as Codicept®, methylmorphine, morphine 3-methyl ether, morphine monomethyl ether, morphine-3-methyl ether, O(3)-methylmorphine, l-codeine, codeine anhydrous

Codeine is an opiate and prodrug of morphine mainly used to treat pain, coughing, and diarrhea. It is commonly used as a recreational drug. It is found naturally in the sap of the opium poppy, Papaver somniferum. It is typically used to treat mild to moderate degrees of pain. Greater benefit may occur when combined with paracetamol (acetaminophen) as codeine/paracetamol or a nonsteroidal anti-inflammatory drug (NSAID) such as aspirin or ibuprofen. Evidence does not support its use for acute cough suppression in children. In Europe, it is not recommended as a cough medicine for those under 12 y

AI overview

Codeine is an opiate derived from the opium poppy plant that doctors use to treat mild to moderate pain, coughing, and diarrhea, often in combination with other medications like paracetamol or ibuprofen. Because it is an opiate, codeine carries risks of recreational misuse and addiction, which is why its use—particularly for cough suppression in children—is increasingly restricted in many countries.

コデイン（英: Codeine）またはメチルモルヒネは鎮痛、鎮咳、および下痢止めの作用のある、μ受容体アゴニストのオピオイドである。塩の形態の硫酸コデインもしくはリン酸コデインとして製品化されている。リン酸コデインは鎮痛剤（疼痛の緩和ケア）や下痢止めとして用いられるが、コデインを還元して製造したジヒドロコデインを鎮咳薬（咳止め薬）として風邪薬に配合するのが一般的である。コデインは1832年にアヘンから単離された。プロドラッグであり、代謝産物の約10%がモルヒネとなる。コデインは世界保健機関(WHO)の必須医薬品に定められている。WHO方式がん性痛治療法では、第2段階の弱オピオイドの第1選択薬に指定されている。日本の処方箋医薬品としては、劇薬に区分される。乱用されやすく、国際条約である麻薬に関する単一条約が、コデインをスケジュールII薬物に指定している。
