USP30-NF25: <1151> PHARMACEUTICAL DOSAGE FORMS
Extended-release tablets are formulated in such manner as to make the contained
medicament available over an extended period of time following ingestion.
Expressions such as “prolonged-action,” “repeat-action,” and
“sustained-release” have also been used to describe such dosage forms.
However, the term “extended-release” is used for Pharmacopeial purposes, and
requirements for Drug release typically are specified in the individual
monographs.
美國藥典30-國家處方集25版: <1151>章節 藥劑形式 大意是說
緩釋錠劑被製成在攝取後，藥物隨著延長時間釋放樣式。換句話說就是在你的腸胃道裡
持續或是延長釋放(相對於速放劑型)。
1.延長釋放(prolonged-action)
2.重複釋放(repeat-action)
3.持續釋放(sustained-release)
之表達方式也被用於描述緩釋劑型(Extended-release dosage form)
“Extended-release”是用於藥典之敘述如說明藥品為緩釋劑型，或是藥品釋放(溶離
試驗)章節。簡單的說在藥典內關於緩釋劑型你會看到“Extended-release”

FormulationGuides/SustainedRelease.aspx
Sustained release (or extended-release) formulations create a steady drug
release profile making the drug substance available over an extended period of
time following ingestion.
Advantages of sustained release formulations include :
Uniform release of drug substance over time
Reduction in frequency of intakes
Reduced adverse side effects
Better patient compliance
持續/緩釋劑型設計成能穩定釋放藥物之模式，使藥物在攝取後能長時間被吸收。
持續釋放之好處為:
1. 隨著時間能均一釋放藥物(相對於速放在於短時間釋放大量藥物)
2. 減少服藥頻率 (如一天兩顆變成一天一顆)
3. 減少副作用
4. 較佳的之病人順從性
