Farmacocinética de los anticuerpos monoclonales

Abstract

Los anticuerpos monoclonales (mAb) representan uno de los grupos terapéuticos de mayor interés en el desarrollo farmacológico. Por toda su complejidad (estructural y funcional), el seguimiento farmacocinético de los fármacos biológicos debería ser imprescindible en la práctica clínica habitual. La absorción de los mAb tras su administración intramuscular o subcutánea se puede producir por vía sanguínea o linfática, y su distribución depende del mecanismo de extravasación, la afinidad del mAb para componentes tisulares y del aclaramiento (Cl) tisular. La eliminación se produce principalmente por proteolisis intracelular tras una endocitosis específica (mediada por receptor) o inespecífica. Por otro lado, la captación y posterior liberación del mAb, la redistribución del flujo sanguíneo por procesos fisiológicos, la formación de complejos y el proceso de reciclaje mediante el receptor de Brambell son los mecanismos fisiológicos que condicionan su variabilidad farmacocinética intraindividual. Además, la inmunogenicidad frente al mAb, el peso del paciente y la cantidad de antígeno diana son los principales factores que afectan a su variabilidad farmacocinética. Palabras clave: Anticuerpo monoclonal, farmacocinética, variabilidad.
