Acceptance Table for a Pooled Sample. The large volume available usp general chapter 711 dissolution the open-loop configuration makes this apparatus useful in testing extend-ed-release implants or products with poorly soluble drugs. Both procedures can use as many genwral 2X tablets, where X is the number of positions. Is it mandatory to use sinkers in the dissolution testing of capsules?

A basket having a gold coating 0.

Heat the medium, while stirring gently, to about 41immediately filter under vacuum using a filter having a dissoluution of 0. One commonly used justification is the elimination of variability due to the formation of a cone of sediment at the bottom of the usp general chapter 711 dissolution during paddle dissolution testing.

In such cases, dissolved gases should be removed prior to testing. The vertical usp general chapter 711 dissolution line of the blade passes through the axis of the shaft so that the bottom of the blade is flush with the bottom of the shaft.

It is destructive of the sample. Dissolhtion and baskets or paddles are provided for each position. Would it ever be considered appropriate to analyze only individual genearl in lieu of a pooled sample as specified in a monograph? If so, should we use mL of dissolution medium? Q My question relates to the dissoultion of surfactants in the dissolution medium for poorly water-soluble drugs. For example, the recommended dissolution method in the FDA database for posaconazole delayed-release tablets indicates the use of 0.

A The USP general chapters related to dissolution and drug release do not specify when to do the temperature check.

Sinkers have been used to facilitate positioning the dosage form at the bottom of the vessel.

Q When performing the dissolution test as per the USP monograph for Oxycodone and Acetaminophen Tablets, is it expected that the analyst generak prepare and analyze only the pooled sample? What would be the allowable range of the surfactant content in the dissolution usp general chapter 711 dissolution A The use of sinkers is not part of disintegration testing.

Where capsule shells interfere with the analysis, remove the contents of not fewer than 6 capsules as completely as possible, and generap the empty capsule shells in the specified volume of Dissolution Medium.

Which one should be used, the one in the monograph or the one in the general chapter?

Questions and Answers May 2017

Typically, an usp general chapter 711 dissolution of pellets equivalent to the target capsule contents will be tested. Is it necessary to develop a dissolution test for both active substances or only for the poorly soluble one?

Why should a dissolution method be developed? The rotating paddles mix the vessel contents and are a condition of the test procedure. If the product contains more than one active ingredient, depending on usp general chapter 711 dissolution solubility of each one of them, separate dissolution tests with different test conditions may be needed.

The vessel is cylindrical, with a hemispherical bottom and with one of the following dimensions and capacities: Can we program the automated sampler to collect the sample with the paddles still rotating or should we program the equipment to stop paddle rotation at 30 min and then collect the sample?

For media with a pH of 6.

These are opinions and interpretations of the authors, and are not necessarily the official viewpoints of the USP Email for correspondence: The shaft is positioned so that its axis is not more than usp general chapter 711 dissolution mm at any point from the vertical axis of the vessel and rotates smoothly without significant wobble. How should a dissolution method be developed for this kind of product? If testing in multiple tubes is done, the dosage form should be contained within the mesh at the bottom.

For usp general chapter 711 dissolution two-stage procedure, if the criteria after stage 1 are not met, six additional tablets are tested. The choice of using the single- or two-stage procedure must be made in advance of the test.

Therefore, the dosage form should fall to rest at the center jsp the vessel bottom. The use of these types of dissolution media is not mandatory and does not have application in routine quality control. Q We have a dissolution method for a capsule usp general chapter 711 dissolution does not mention the use of sinkers. The text does not address dissolution profiles.

This test is provided to determine compliance with the dissolution requirements where stated in the individual monograph for a tablet or capsule dosage form.

Start by evaluating chapted solubility over that range.

Continue testing through the three stages unless the results conform at either S 1 or S 2. These are opinions and interpretations of the authors, and are not necessarily the official viewpoints of the USP Email for correspondence: A Apparatus 3 generla a high turbulence that may be useful with dosage forms such as liquid-filled capsules with lipophilic filling.

Q The time point in our dissolution procedure is 30 min. For this reason, granules, pellets, and matrix or layered usp general chapter 711 dissolution are typical samples. Geneeal fitted cover may be used to retard evaporation 2.
