Preparation for Administration

Adrucil is supplied in a pharmacy bulk package consisting of a vial. The pharmacy bulk package can be used to prepare doses for more than one patient. It is not supplied with a sterile transfer device, which is required for dispensing when multiple doses will be prepared from the single vial. The 50 mL vial is only intended for preparation in a Pharmacy Admixture Service under appropriate conditions for cytotoxic drugs [see References (15)]. Store vial at room temperature.

Using aseptic conditions, penetrate the container closure once with a suitable sterile transfer device or dispensing set that allows measured distribution of the contents. Record the date and time the vial was opened on the vial label. Discard the pharmacy bulk package 4 hours after penetration of the container closure.

Withdraw the calculated dose for an individual patient into a sterile syringe. Inspect the solution in syringe for particulate matter and discoloration prior to administration or further dilution. Discard syringe if the solution is discolored or contains particulate matter.

Do not administer in the same intravenous line concomitantly with other medicinal products.

For bolus administration, store undiluted Adrucil in the syringe for up to 4 hours at room temperature (25°C). Administer Adrucil as an intravenous bolus through an established intravenous line.

Store diluted solutions of Adrucil for up to 4 hours at room temperature (25°C) prior to administration to the patient. For intravenous infusion regimens, administer through a central venous line using an infusion pump.
