Overview
Ganciclovir is a nucleoside analogue antiviral drug that inhibits viral DNA polymerase, making it effective against cytomegalovirus (CMV) and other herpesviruses. It is commonly used in immunocompromised patients, such as those with HIV/AIDS or organ transplant recipients, to prevent or treat CMV infections. The drug is available in oral, intravenous, and ocular formulations, depending on the clinical need. First synthesized in the 1980s, ganciclovir has become a critical component in managing CMV-related complications. Its mechanism of action involves competitive inhibition of viral DNA polymerase, which disrupts viral replication. Despite its efficacy, the drug requires careful monitoring due to potential side effects, including bone marrow suppression.
Physical and Chemical Properties
Ganciclovir is a white to off-white crystalline powder with a molecular weight of 255.23 g/mol. It is soluble in water and dimethyl sulfoxide (DMSO), which facilitates its formulation into various pharmaceutical preparations. The compound decomposes at approximately 250°C, and its stability is best maintained when stored at 2-8°C in a dry, airtight environment. The molecular formula of ganciclovir is C9H13N5O4, and its structure includes a guanine-like moiety, which is essential for its antiviral activity. The drug's solubility and stability profiles are critical for its bioavailability and efficacy in clinical settings. Proper handling and storage are necessary to maintain its chemical integrity.
Main Applications
Ganciclovir is primarily used to treat and prevent CMV infections in immunocompromised individuals, such as those undergoing organ transplantation or with HIV/AIDS. It is also employed in the management of CMV retinitis, a sight-threatening condition in AIDS patients. The drug's intravenous form is often used for severe infections, while the oral form is suitable for maintenance therapy. In addition to its clinical uses, ganciclovir is utilized in research settings to study herpesvirus infections and antiviral resistance. Its ability to inhibit viral DNA polymerase makes it a valuable tool for understanding viral replication mechanisms. However, its use is limited by potential toxicity, necessitating careful patient monitoring.
Safety and Storage
Ganciclovir must be handled with care due to its potential to cause hematologic toxicity, including neutropenia and thrombocytopenia. Personnel should use appropriate protective equipment, such as gloves and masks, when handling the drug. Storage conditions are critical to maintaining its stability; the compound should be kept at 2-8°C in a dry, airtight container. Patients receiving ganciclovir therapy require regular blood tests to monitor for adverse effects. The drug is contraindicated in pregnant women due to its teratogenic potential. Proper disposal methods should be followed to prevent environmental contamination and ensure compliance with regulatory guidelines.
B2B Procurement Guide
When procuring ganciclovir in bulk, B2B buyers should prioritize suppliers who adhere to Good Manufacturing Practices (GMP) and provide certificates of analysis (CoA) to verify product quality. The reference price range varies depending on the quantity and supplier, so obtaining multiple quotes is advisable. Buyers should also consider the drug's shelf life and storage requirements to ensure optimal efficacy. It is essential to establish a reliable supply chain to avoid shortages, especially for critical care settings. Partnering with reputable manufacturers and distributors can help mitigate risks associated with counterfeit or substandard products. Buyers should also stay informed about regulatory changes that may impact procurement processes.
