CATEGORIES

Antineoplastic Agents Immunosuppressive Agents Cross-Linking Reagents Antineoplastic and Immunomodulating Agents Platinum Compounds

CHEMICAL FORMULA

C6H12N2O4Pt

COMPOSITION

Carboplatin 150 MG

INDICATION

For the initial treatment of advanced ovarian carcinoma in established combination with other approved chemotherapeutic agents. One established combination regimen consists of PARAPLATIN and cyclophosphamide. It is also indicated for the palliative treatment of patients with ovarian carcinoma recurrent after prior chemotherapy, including patients who have been previously treated with cisplatin.

PHARMACODYNAMICS

Carboplatin is an antineoplastic in the class of alkylating agents and is used to treat various forms of cancer. Alkylating agents are so named because of their ability to add alkyl groups to many electronegative groups under conditions present in cells. They stop tumor growth by cross-linking guanine bases in DNA double-helix strands - directly attacking DNA. This makes the strands unable to uncoil and separate. As this is necessary in DNA replication, the cells can no longer divide. In addition, these drugs add methyl or other alkyl groups onto molecules where they do not belong which in turn inhibits their correct utilization by base pairing and causes a miscoding of DNA. Alkylating agents are cell cycle-nonspecific. Alkylating agents work by three different mechanisms all of which achieve the same end result - disruption of DNA function and cell death.

MECHANISM

Alkylating agents work by three different mechanisms: 1) attachment of alkyl groups to DNA bases, resulting in the DNA being fragmented by repair enzymes in their attempts to replace the alkylated bases, preventing DNA synthesis and RNA transcription from the affected DNA, 2) DNA damage via the formation of cross-links (bonds between atoms in the DNA) which prevents DNA from being separated for synthesis or transcription, and 3) the induction of mispairing of the nucleotides leading to mutations.

ABSORPTION

The Cmax values and areas under the plasma concentration versus time curves from 0 to infinity (AUC inf) increase linearly with dose, although the increase was slightly more than dose proportional. Carboplatin exhibits linear pharmacokinetics.

VOLUME DISTRIBUTION

16 L [apparent volume of distribution, 30 minute IV infusion of 300 mg/m^2 to 500 mg/m^2]

ROUTE ELIMINATION

The major route of elimination of carboplatin is renal excretion. After 24 hours, all of the platinum is recovered in the urine as carboplatin. Whether biliary excretion occurs is not known.

HALF LIFE

Initial plasma half-life (alpha) = 1.1 to 2 hours; Post distribution plasma half-life (beta) = 2.6 - 5.9 hours.

TOXICITY

Toxic by ingestion. May be create toxic effect through inhalation or skin contact. May cause reproductive defects. May act as a sensitizer. ORL-RAT LD50 343 mg kg-1; SCN-RAT LD50 72 mg kg-1; IPN-MUS LD50 118 mg kg-1

FOOD INTERACTIONS

Avoid echinacea as it may decrease effectiveness of immunosuppresants like carboplatin

SIDE EFFECTS

Chance of getting an infection. Wash hands often. Stay away from people with infections, colds, or flu. Anemia, low white blood cell count, and low platelet count. Feeling tired or weak. Upset stomach or throwing up. Many small meals, good mouth care, sucking hard, sugar-free candy, or chewing sugar-free gum may help. Skin irritation. Hair loss. Hair most often grows back when this drug is stopped. Allergic side effects may rarely happen.
