A drug product or service or group of drug products and solutions could meet up with a number of of these requirements that point out it offers demonstrable complications for compounding. FDA proposes to use precisely the same requirements when considering drug solutions or types of drug items for inclusion on both the DDC Record for segment 503A or perhaps the DDC Record for segment 503B on the FD&C Act, Whilst the application of the criteria may possibly bring on various conclusions for each checklist.
It should click here be employed with caution in patients with uncontrolled hypertension, unstable angina, or the latest myocardial infarction.
