Cisplatin 50 mg Injection — Platinum-Based Chemotherapy for Solid Tumours Cisplatin 50 mg Injection contains cisplatin, a platinum-derived chemotherapy agent used in the treatment of numerous cancers including testicular, ovarian, bladder, lung, and head & neck cancers. It works by binding to DNA in cancer cells and disrupting their ability to divide and grow, leading to cell death. Given by intravenous infusion under strict clinical supervision, cisplatin is often used in combination with other anticancer drugs in multi-drug chemotherapy protocols. Due to its potent effects and potential side effects — such as kidney toxicity, nausea, low blood counts, and hearing changes — close medical monitoring and supportive care (hydration, blood tests) are essential.
