I just took another look at the USP monograph for Carbidopa, and it applies to ALL such formulations, i.e. generic and non-generic, and it categorically states that it cannot have less than 90% nor more than 110% of the labelled amount. This 10% deviation allows for variation in the compression of dosage forms, that is the tablet or the capsule. Of course they cannot check every single batch, but they are checked randomly by the federal and by the state labs, and when found to be violative, they are recalled. Michel Margosis
