Lobaplatin is a platinum-based antineoplastic agent used in the treatment of various types of cancer. It is a third-generation platinum compound, following cisplatin and carboplatin, and is known for its improved safety profile and efficacy.
Chemical Structure[edit | edit source]
Lobaplatin is a complex of platinum with a cyclobutane dicarboxylate ligand and a 1,2-diaminocyclohexane carrier ligand. This structure allows it to form cross-links with DNA, inhibiting DNA replication and transcription, which ultimately leads to cell death.
Mechanism of Action[edit | edit source]
Lobaplatin exerts its antitumor effects by binding to DNA and forming intrastrand cross-links between adjacent guanine bases. This cross-linking disrupts the DNA double helix, preventing DNA replication and transcription, and triggering apoptosis in rapidly dividing cancer cells.
Clinical Uses[edit | edit source]
Lobaplatin is primarily used in the treatment of breast cancer, ovarian cancer, and small cell lung cancer. It is often administered in combination with other chemotherapeutic agents to enhance its efficacy.
Side Effects[edit | edit source]
Common side effects of Lobaplatin include myelosuppression, nausea, and vomiting. It is generally better tolerated than earlier platinum-based drugs, with a lower incidence of nephrotoxicity and neurotoxicity.
Pharmacokinetics[edit | edit source]
Lobaplatin is administered intravenously and exhibits a biphasic elimination pattern. It is primarily excreted through the kidneys, and dose adjustments may be necessary in patients with renal impairment.
Development and Approval[edit | edit source]
Lobaplatin was developed to overcome the limitations of earlier platinum drugs, such as cisplatin and carboplatin. It has been approved for use in several countries, although its availability may vary.
