What is Q dissolution?
What is Q? Q, as it relates to dissolution is commonly used in the USP for immediate release and delayed release dosage forms. The quantity of Q is the amount of dissolved active ingredient specified in the individual monograph expressed as a percentage of the labeled content.
Is content uniformity A stability indicating test?
c) Assay: A specific, stability-indicating assay to determine strength (content) should be included for all new drug products. Results of content uniformity testing for new drug products can be used for quantitation of drug product strength, if the methods used for content uniformity are also appropriate as assays.
What is the Q value in dissolution?
USP defines Q as the quantity or the “amount of dissolved Active Pharmaceutical Ingredient (API) specified in an individual monograph, expressed as a percentage of the labeled content of the dosage unit…”. When we look at a Q value, we are looking at what percent has dissolved at that time for that product.
