Formulary(NF)were given official status.The Harrison Narcotic Act is passed to control the importation,sale,and distribution of opium and its derivatives,as well as other narcotic analgesics.The Food,Drug,and Cosmetic Actbecomes law.This is the Federal Food,Drug,and Cosmetic Act to protect the pnblic health and protect physicians from irresponsible drug manufacturers.This act is enforced by the Food and Drug Administration(FDA).The Durham-Humphrey Amendment defines the drugs that may sold by the pharmacist only on prescripition.The Kefauver-Harris Law is passed as an amendment to the Food,Drug,and Cosmetic Act of 1938.This act requires proof of safety and efficacy of all drugs introduced since 1938.Drugs in use before that time have not been reviewed but are under study.1971 The Controlled Subsances Act becomes effective;this act lists requirements for the control,sale,and dispensation of narcotics and dangerous drugs.Five schedules of controlled substances have been defined,Schedule I to Schedule V generally define drugs of decreasing potential for abuse,increasing medical use,and decreasing physical dependence.Examples of each schedule are as follows:Schedule:All nonresearch use isillegal;examples:heroin,marijuana,LSD,peyote,and mescalineSchedule:No telephone prescriptions,no refills;examples:opium,morphine,certain barbiturates Schedule:Prescription must be rewritten after 6 months,or five refills;examples:certain opioid doses,glutethimide(Doriden),and some other barbituratesSchedule:Prescription must be rewritten after 6 months or five refills;penalties for illegal possession differ from those for Schedule drugs;examples:phenobarbital,barbital,chloral hydrate,meprobamate(Equanil,Miltown),and zolpidem(Ambin)Schedule:As for any nonopioid prescription drug;examples:narcotics contanining nonnarcotics in mixture form,such as cough preparations or Lomotil(diphenoxylate,narcotic with 2.5 mg and atropine sulfate,nonnarcotic).,Raus Respiratory Care Pharmacology.7th edition,2008,Mosby,美國藥物管理之發展The first Food and Dr,1906 國會通過第一個藥物食品法;美國藥典及國家處方集取 得官方認可1914 通過Harrison麻醉藥品管理條例，對鴉片及其衍生物及 其他麻醉藥品之輸入、販售及配送進行管理1938 制定食品、藥品及化妝品法，也就是現行用以保障公共 衛生及醫師免於不負責任的藥廠影響的聯邦法律，由藥 物食品局(FDA)執行1952 Durham-Humphrey修正案，規定藥物需有處方才得由 藥師販售 Kefauver-Harris法案修正1938年之食物、藥品及化妝 品法，本法案要求1938年後上市之藥品需有安全性及有 效性之證明，1938年之前之藥物雖然沒有重新檢討，但 仍需重新研究1971 管制藥品法生效，本法列出有關麻醉及危險藥品之管制、販售及配送等措施。分為五等級，級數越高，其濫用之 可能性越低，醫療用途越高及成癮性越低,美國藥物管理之發展,1906 國會通過第一個藥物食品法;美國藥典及國家處方集取,第一級(schedule):非研究用途皆為非法，如heroin,marijuana,LSD,peyote&mescaline第二級(schedule):不得以電話處方，非經診察不得單純領藥(refill)，如:opium,morphine,certain barbituates,amphetamines第三級(schedule):處方在6個月後需重新開立，或只可單純領藥五次，如某些opioid doses，glutethimide(Doriden)，和某些barbituates第四級(schedule):處方在6個月後需重新開立，或只可單純領藥五次，但非法擁有之處罰與第三級不同，如phenobarbital,barbital,choral hydrate,meprobamate(Equanil,Miltown)和zolpidem(Ambien)第五級(schedule):非鴉片類藥物，如含有麻醉與非麻醉之混合藥物，例如:咳嗽藥或Lomotil(diphenoxylate,narcotic with 2.5mg and atropine sulfate,nonnarcotic),美國藥物管理之發展,第一級(schedule):美國藥物管理之發展,台灣藥政紀要,1983優良藥品製造標準(GMP)1985優良藥品調劑作業規範(GDP)1988完成實施藥品GMP制度1990實施藥品再分類1993藥事法公布施行1993新藥監視制度-要求執行國內臨床試驗1994藥事法施行細則公佈施行1995無菌製劑確效作業實施1996藥品優良臨床試驗規範(GCP)1998成立財團法人醫藥品查驗中心(CDE)1998藥品非臨床試驗優良操作規範(GLP)1998藥品非臨床試驗安全性規範1999管制藥品管理條例公佈施行1999建立全國藥物不良反應(ADR)通報系統,1999推動醫療器材GMP1999修訂藥品優良製造規範(cGMP)2000罕見疾病防治及藥物法公布施行2000藥害救濟法公布施行2000醫療器材重新分類分級管理2001成立財團法人藥害救濟基金會(TDRF)2002啟動海外藥廠查核制度2003推動優良調劑及給藥安全作業規範(GDDP)2004實施銜接性試驗評估2004藥事法修法,台灣藥政紀要1983優良藥品製造標準(GMP)1999推動,管制藥品的分類在台灣,管制藥品依行政院衛生署公告之管制藥品管理條例第三條之說明如下：管制藥品係指下列藥品：一、成癮性麻醉藥品。二、影響精神藥品。三、其他認為有加強管理必要之藥品前項管制藥品限供醫藥及科學上之需用，依其習慣性、依賴性、濫用性及社會危害之程度，分四級管理。其分級及品項，由中央衛生主管機關設置管制藥品審議委員會審議後，報請行政院核定後公告之。案例：第一級管制藥品：Morphine、Heroin、Opium、Cocaine等。第二級管制藥品：Codeine、Hydromorphine、Fentanyl、Pethidine、Methsdone 等。第三級管制藥品：Tramadol、Ketamine等第四級管制藥品：Diazepam、Estazolam等,管制藥品的分類在台灣管制藥品依行政院衛生署公告之管制藥品管,呼吸照护药理学简介课件,Naming Drugs(藥物之命名),Chemical name(化學名)：藥物的化學結構Code name(編號名)：藥廠給予，可能成為藥物的試驗性化學品一個名稱Official name：正式名Generic name：學名Brand(trade)name：商標名,Naming Drugs(藥物之命名)Chemical n,Generic Name(學名),當化學產物有治療的效果，而藥廠想將之上市，美國命名協會(United States Adopted Name,USAN)給予這個化學物的名稱。與編號(採用數字)不同的是，學名是基於藥物的化學結構，如isoproterenol有isopropyl group連在胺基酸鏈的末端氮上(terminal nitrogen)與商標名(brand name)不同的是generic name是非專利名(nonproprietary),Generic Name(學名)當化學,Official Name(正式名),當試驗藥品完全通過可做一般用途，且被收錄於美國藥典-國家處方集(United States pharmacopeia-National Formulary)，學名就成為正式名，因為正式核可的藥品可能由很多藥廠以不同的名字在市場銷售，建議臨床醫師使用無專利性的正式名，而非商標名。,Official Name(正式名)當試驗藥品完全通過,台灣藥典,台灣並沒有如美國藥典之國家處方集收錄通過臨床驗的藥品。在台灣藥品一旦通過新藥上市申請衛生署會給予藥品許可證號，我們可以利用衛生署網頁上的【藥品醫材化妝品許可證號查詢】來確認。想要了解藥品相關的資訊可以查詢【MIMS台灣藥品手冊、MIMS簡明處方藥典、常用藥品手冊】等，這些收錄台灣上市藥品的藥品資料，不過內容較為簡略。但若想要更清楚藥品完整的資料，就必須使用【各國的藥典】來查詢，或利用藥品資料整合軟體，如：Micromedex。,台灣藥典台灣並沒有如美國藥典之國家處方集收錄通過臨床驗的藥品,衛生署藥品醫材化妝品許可證號查詢,衛生署藥品醫材化妝品許可證號查詢,MIMS台灣藥品手冊、MIMS簡明處方藥典,MIMS台灣藥品手冊、MIMS簡明處方藥典,Trade
