(cytarabine liposome injection) 50 mg Vial
For Intrathecal Use Only
DepoCyt® (cytarabine liposome injection) should be administered only under the supervision of a qualified physician experienced in the use of intrathecal cancer chemotherapeutic agents. Appropriate management of complications is possible only when adequate diagnostic and treatment facilities are readily available. In all clinical studies, chemical arachnoiditis, a syndrome manifested primarily by nausea, vomiting, headache and fever, was a common adverse event. If left untreated, chemical arachnoiditis may be fatal. The incidence and severity of chemical arachnoiditis can be reduced by coadministration of dexamethasone (see WARNINGS). Patients receiving DepoCyt should be treated concurrently with dexamethasone to mitigate the symptoms of chemical arachnoiditis (see DOSAGE AND ADMINISTRATION).
DepoCyt® (cytarabine liposome injection) is a sterile, injectable suspension of the antimetabolite cytarabine, encapsulated into multivesicular lipid-based particles. Chemically, cytarabine is 4amino-1 -β-D-arabinofuranosyl-2(1H)-pyrimidinone, also known as cytosine arabinoside (C9H13N3O5, molecular weight 243.22).
The following is an artist's rendition of a DepoCyt particle:
