Illinois Multistate Pharmacy Jurisprudence Examination (MPJE) Practice Exam

To classify codeine as a Schedule 5 controlled substance, the compounded dose limit is set at no more than 200 mg of codeine per 100 milliliters. This threshold is significant because it distinguishes Schedule 5 substances, which have a lower potential for abuse compared to those in higher schedules. The 200 mg per 100 milliliters limit is a regulatory measure to ensure that such preparations remain in a lower regulatory category, reflecting their accepted medical use and lower risk of addiction or dependence.

It's important to understand that these regulations help maintain a balance between the availability of useful medications and the need to control substances that could be abused. The specific limit of 200 mg per 100 milliliters dictates how codeine can be formulated in pharmaceutical preparations without moving it into a higher schedule, which would impose stricter controls and limitations.
