Ariplat (Cisplatin) injection for IV infusion contains 10 mg and 50 mg of Cisplatin which is a platinum coordination compound.

Description

Cisplatin binds with DNA to form intrastrand crosslinks and adducts that cause changes in the conformation of the DNA and affect DNA replication. Cisplatin then binds with DNA, RNA, or other macromolecules at two sites to form interstrand and intrastrand links. These intrastrand adducts significantly alter the conformation of DNA and inhibit DNA polymerase, RNA polymerase, RNA translocation, and other key enzymes. Cisplatin causes cell cycle arrest in the G2-phase and then induces programmed cell death or apoptosis. Cisplatin injection is indicated for the treatment of Testicular, Ovarian and Bladder Cancer.

Presentation

    Ariplat 10 Injection: Each vial contains Cisplatin BP 10 mg, as sterile preservative free 10 ml concentrated solution for IV Infusion.
    Ariplat 50 Injection: Each vial contains Cisplatin BP 50 mg, as sterile preservative free 50 ml concentrated solution for IV Infusion.

Indications

    Metastatic Testicular Tumors: In established combination therapy with other approved chemotherapeutic agents in patients with metastatic testicular tumors who have already received appropriate surgical and/or radiotherapeutic procedures.

    Metastatic Ovarian Tumors: In established combination therapy (e.g.Cisplatin with Cyclophosphamide) with other approved chemotherapeutic agents in patients with metastatic ovarian tumors who have already received appropriate surgical and/or radiotherapeutic procedures.
    Cisplatin Injection, as a single agent, is indicated as secondary therapy in patients with metastatic ovarian tumors refractory to standard chemotherapy who have not previously received Cisplatin Injection therapy.

    Advanced Bladder Cancer: Cisplatin Injection is indicated as a single agent for patients with transitional cell bladder cancer which is no longer amenable to local treatments, such as surgery and/or radiotherapy.

Dosage & Administration

    Cisplatin Injection is administered by slow intravenous infusion. Pretreatment hydration with 1 to 2 liters of fluid infused for 8 to 12 hours prior to a Cisplatin Injection dose is recommended.
    Needles or intravenous sets containing aluminum parts that may come in contact with Cisplatin Injection should not be used for preparation or administration. Aluminum reacts with Cisplatin Injection, causing precipitate formation and a loss of potency. All parenteral drug products should be inspected visually prior to administration and should not be used if precipitates, visible particles and/or discoloration is present.

    Metastatic Testicular Tumors: The usual dose for the treatment of testicular cancer in combination with other approved chemotherapeutic agents is 20 mg/m2 IV daily for 5 days per cycle.

    Metastatic Ovarian Tumors: The usual dose for the treatment of metastatic ovarian tumors is 75 to 100 mg/m2 IV in combination with Cyclophosphamide 600 mg/m2 IV per cycle once every 4 weeks. In combination therapy, Cisplatin Injection and Cyclophosphamide are administered sequentially.
    As a single agent, Cisplatin Injection should be administered at a dose of 100 mg/m2 IV per cycle once every four weeks.

    Advanced Bladder Cancer: Administered as a single agent at a dose of 50 to 70 mg/m2 IV per cycle once every 3 to 4 weeks depending on the extent of prior exposure to radiation therapy and/or prior chemotherapy. For heavily pretreated patients an initial dose of 50 mg/m2 per cycle repeated every 4 weeks is recommended.

    Preparation for Administration: To prepare for administration Cisplatin is diluted in 2 liters of 5% Dextrose in 1/2 or 1/3 normal saline containing 37.5 g of mannitol, and infused over a 6-to 8-hour period. If diluted solution is not to be used within 6 hours, protect solution from light. The diluted solution is intended to be used within 24 hours and any unused portion should be discarded after this period.

    Precautions during Handling: Caution should be exercised in handling the aqueous solution. Procedures for proper handling and disposal of anticancer drugs should be utilized. To minimize the risk of dermal exposure, always wear impervious gloves when handling vials and IV sets containing Cisplatin. If Cisplatin contacts the skin or mucosa, immediately and thoroughly wash the skin with soap and water and flush the mucosa with water.

Contrainidications

    Cisplatin is contraindicated in patients with preexisting renal impairment. Cisplatin should not be employed in myelosuppressed patients, or in patients with hearing impairment. Cisplatin is contraindicated in patients with a history of allergic reactions to Cisplatin or other platinum-containing compounds.

Warning & Precautions

    Pregnancy: Pregnancy category D, Cisplatin can cause fetal harm. Pregnancy should be avoided during Cisplatin treatment and for at least 14 months after the last dose.
    Nursing mothers: Cisplatin has been reported to be found in human milk; patients receiving Cisplatin should not breast-feed.
    Pediatric use: Safety and effectiveness in pediatric patients have not been established.
    Geriatric use: Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and renal function should be monitored.
    Renal impaired patients: Cisplatin is known to be substantially excreted by the kidney and is contraindicated in patients with preexisting renal impairment.

    Peripheral blood counts should be monitored weekly. Liver function should be monitored periodically. Neurologic examination should also be performed regularly.

Side effects

    Nephrotoxicity: Dose-related and cumulative renal insufficiency, including acute renal failure. Ototoxicity: Tinnitus and/or hearing loss in the high frequency range. Hematologic: Myelosuppression, leukopenia, thrombocytopenia, anemia, neutropenia. Gastrointestinal: Nausea and vomiting, anorexia, diarrhoea. Other Toxicities: Serum electrolyte disturbances, hyperuricemia, neurotoxicity, ocular toxicity, anaphylactic-like reactions, hepatotoxicity.

Drug interaction

    Plasma levels of anticonvulsant agents may become subtherapeutic during Cisplatin therapy.
    Response duration can be adversely affected when pyridoxine is used in combination with hexamethylmelamine and Cisplatin.

Use in special groups
