The manufacturer states that constituted solns are stable for 8 hr at a room temp not exceeding 25 °C. However, other information indicates that the drug may be stable for a much longer time. At a concn of 15 mg/ml in sterile water for injection or at concns of 2 & 0.5 mg/ml in dextrose 5% in water, no decomp occurs in 24 hr at 22-25 °C. Aqueous solns of 10 mg/ml prefilled into plastic syringes exhibited no decomp in 5 days at 4 °C & only a 3% loss in 24 hr at 37 °C.

Mild and transient elevations in serum aminotransferase levels are found in up to one-third of patients taking carboplatin. However, clinically apparent acute liver injury from carboplatin is extremely rare and the characteristics of such injury have not been well defined. In addition, carboplatin has been used in combination with other alkylating agents in high doses in conditioning regimens in preparation of hematopoietic cell transplantation which may be associated with instances of sinusoidal obstruction syndrome, which can be severe and lead to acute liver failure. Onset of sinusoidal obstruction syndrome is generally within 10 to 20 days of transplantation and presents with right upper quadrant pain, hepatic tenderness, weight gain, edema and ascites, followed by jaundice. The role of carboplatin in causing these cases of sinusoidal obstruction syndrome has not been well defined.
Carboplatin is usually given in combination with other antineoplastic agents and adverse events that occur with these combinations cannot always be attributed to carboplatin. In this regard, individual case reports of reactivation of hepatitis B, acute hepatic necrosis, sinusoidal obstruction syndrome and severe hyperammonemic coma (without liver injury) have been described after chemotherapeutic regimens that include carboplatin and other platinum coordination complexes such as cisplatin and oxaliplatin. In most of these instances, it is difficult to assign a specific role for carboplatin in causing the injury.
Likelihood score: D (possible cause of clinically apparent liver injury).
A higher percentage of a dose of carboplatin is excreted in the urine than cisplatin & most of the dose is excreted during the initial 24 hr after injection.
