Identification
- Summary
Palivizumab is a monoclonal anti respiratory syncytial virus F protein antibody used to prevent serious sequelae caused by respiratory syncytial virus infection in pediatric patients.
- Brand Names
- Synagis
- Generic Name
- Palivizumab
- DrugBank Accession Number
- DB00110
- Background
Humanized monoclonal antibody (IgG1k) produced by recombinant DNA technology, directed to an epitope in the A antigenic site of the F protein of respiratory syncytial virus (RSV). Synagis is a composite of human (95%) and murine (5%) antibody sequences. The human heavy chain sequence was derived from the constant domains of human IgG1 and the variable framework regions of the VH genes Cor (1) and Cess (2). The human lightchain sequence was derived from the constant domain of Ck and the variable framework regions of the VL gene K104 withJk-4. Palivizumab is expressed from a stable murine (mouse) myeloma cell line (NS0). Palivizumab is composed of to heavy chains (50.6 kDa each) and two light chains (27.6 kDa each), contains 1-2% carbohydrate by weight and has a molecular weight of 147.7 kDa +/- 1 kDa (MALDI-TOF)

- Contraindications & Blackbox Warnings
Avoid life-threatening adverse drug eventsImprove clinical decision support with information on contraindications & blackbox warnings, population restrictions, harmful risks, & more.Avoid life-threatening adverse drug events & improve clinical decision support.- Pharmacodynamics
Synagis exhibits neutralizing and fusion-inhibitory activity against Respiratory syncytial virus (RSV). These activities inhibit RSV replication or spread. Synagis is given to prevent the development of lower respiratory tract disease in pediatric patients.
- Mechanism of action
Palivizumab binds to the fusion glycoprotein of RSV. This prevents its binding and uptake by host cellular receptors.
