Developmental data should be considered when determining the need for either a dissolution procedure or a particle size distribution procedure.〔【出典】ICHガイドライン 〕
Developmental data should be considered when determining the need for either a dissolution procedure or a particle size distribution procedure for these formulations.〔【出典】ICHガイドライン 〕
Dissolution testing should be performed at release. This test may be performed as an in-process test when justified by product development data.〔【出典】ICHガイドライン 〕
For immediate-release drug products where changes in dissolution rate have been demonstrated to significantly affect bioavailability, it is desirable to develop test conditions which can distinguish batches with unacceptable bioavailability.〔【出典】ICHガイドライン 〕
Where dissolution significantly affects bioavailability, the acceptance criteria should be set to reject batches with unacceptable bioavailability.〔【出典】ICHガイドライン 〕
(1) Immediate-release dosage forms are preparations showing a release pattern of active substance(s) that is not intentionally modified and is generally dependent on the intrinsic solubility of the active substance.〔【出典】第十六改正日本薬局方(平成23年3月24日 厚生労働省告示第65号)〕
(9) The test for Content Uniformity under the Uniformity of Dosage Units and the Dissolution Test are not intended to apply to the crude drug component of preparations which are prepared using crude drugs or preparations related to crude drugs as raw materials.〔【出典】第十六改正日本薬局方(平成23年3月24日 厚生労働省告示第65号)〕
BでAを溶出する
dissolve out A with B
In vitro/in vivo相関が確立された場合、それは適切な溶出試験の規格値を選択するのに役立つであろうし、製剤や製造工程の変更後に必要となる生物学的同等性試験を減らすことを可能にするかもしれない。
A successful correlation can assist in the selection of appropriate dissolution acceptance criteria, and can potentially reduce the need for further bioequivalence studies following changes to the product or its manufacturing process.〔【出典】ICHガイドライン 〕
こうした場合には、溶出試験を適用する必要はないと思われる。
In such cases dissolution testing may not be necessary.〔【出典】ICHガイドライン 〕
For example, the presence of trace amounts of a protease might only be detected by product degradation that occurs over an extended time period; or, in some cases, divalent ions leached from the container closure system might change the stability profile because of the activation of trace proteases not detected in stability studies of the pre-change product.〔【出典】ICHガイドライン 〕
A surrogate test (e.g., dissolution) (see Decision tree 4(3)) can generally be used to monitor product performance, and polymorph content should only be used as a test and acceptance criterion of last resort.〔【出典】ICHガイドライン 〕
また、溶出のプロフィールも同様のものが得られなければならない。
A similar elution profile should result.〔【出典】ICHガイドライン 〕
If changes in formulation or process variables significantly affect dissolution and such changes are not controlled by another aspect of the specification, it may also be appropriate to adopt dissolution test conditions which can distinguish these changes (see Decision Tree #7(2)).〔【出典】ICHガイドライン 〕
Otherwise, test conditions and acceptance criteria should be established which pass clinically acceptable batches (see Decision Tree #7(2)).〔【出典】ICHガイドライン 〕
