The draft guidance is a proposed revision of section We originally issued CPG b. Since its adoption in , the CPG has stated that, in light of the USP standards and under certain conditions, the agency does not deem it necessary that stability studies be conducted on drugs that are repackaged into unit-dose containers. Therefore, the CPG has stated that we do not intend to initiate enforcement action against any unitdose repackaging firm for failure to have stability studies supporting expiration dates, provided certain conditions are met, including that the expiration date does not exceed 6 months.
At the time the CPG was adopted, this recommendation was substantially PO Frm Fmt Sfmt comparable to the USP standards on expiration dating of nonsterile unit-dose repackaged drug products.

The packaging is usually a foil or plastic pouch. Several systems are commercially available in the U. Semi-automated Unit-dose Packaging Systems Semi-automated unit-dose packaging systems are considerably more affordable for pharmacy departments with very conservative budgets and are more flexible to meet the needs of the facility.

Most of the semi-automated systems are stand-alone systems and not connected with the hospital's operating system; however, most of the software that operates these systems is connected to an Internet drug database, such as First Data Bank. This allows the necessary information that is needed for the label to automatically populate in the software based on the NDC numbers and minimizes labeling errors. The labels can be manually modified to harmonize descriptions with the hospitals' systems and barcode labeling formats.
Partial tablets and compounded medications can also be added to the software library for future packaging. Again, the packaging is usually foil or plastic packets and takes up very little space in the dispensing cabinets or on the shelves in the pharmacy.
The disadvantage to a semi-automated unit-dose packaging system is that a dedicated person has to operate it, and, depending on the quantity of repackaged medication needed by the facility, it could require a full FTE position. Again, the information for each system should be reviewed and visits made to facilities that own and operate these systems.
Demonstrations are often set up at trade shows too.

The cost of materials is minimal, and the labeling software is easily affordable, but it can require a lot of manpower depending on the quantity that needs to be repackaged. Most of the manual systems for the solid dosage forms are blister packs. The software will create the labeling and barcoding for the blister packs and is printed on foil-backed paper that adheres to and seals the blister packs with adhesive or heat.
When choosing the materials, make sure that they meet USP standards.
Oral liquids can be drawn up into oral syringes or added to oral vials. Sometimes a peristaltic pump can be useful in filling the syringes or vials, but usually the pump must be calibrated for each liquid due to the differences in viscosity. When repackaging oral suspensions, the suspensions must be shaken or agitated often to ensure that the medication is uniformly distributed throughout the liquid base during the repackaging process.
