Packaging and storage— Preserve in Containers for Sterile Solidsas described under Injections á1ñ.
USP Reference standards á11ñ USP Endotoxin RS.USP Human Chorionic Gonadotropin RS.USP Menotropins RS.
Constituted solution— At the time of use,it meets the requirements for Constituted Solutionsunder Injections á1ñ.
Bacterial endotoxins á85ñ It contains not more than 2.5USP Endotoxin Units per USP Follicle-stimulating Hormone Unit.
pHá791ñ: between 6.0and 7.0,in the solution constituted as directed in the labeling.
Uniformity of dosage units á905ñ Open 10containers and accurately weigh each individual container and its contents,taking care to preserve the identity of each container.Remove the contents of each container by rinsing thoroughly with water,dry at 105to constant weight,and reweigh.Calculate for each container the net weight of its contents by subtracting the weight of the dry,empty container from its initial gross weight.Determine the average weight of the contents and the relative standard deviation (see Calculation of the Relative Standard Deviationunder Uniformity of Dosage Units á905ñ).The requirements are met if the weight of the contents of each container does not deviate from the average weight by more than 5.0%and the relative standard deviation of the 10containers is not greater than 3.0%.If the requirements of the test are not met,test 20additional containers.The requirements are met if the net weight of not more than 1container of the 30deviates by more than 7.5%from the average weight of the contents of the 30containers and the relative standard deviation of the 30containers is not greater than 3.3%.
