General description

Estructura química: macrólido

Application

La rifampicina se utiliza para el tratamiento de la tuberculosis y de las infecciones micobacterianas relacionadas con la tuberculosis. Se utiliza ampliamente como antiprurítico en la enfermedad hepática colestática autoinmunitaria, la cirrosis biliar primaria (PBC). Se ha demostrado que causa hepatitis.

Biochem/physiol Actions

La rifampicina inhibe el ensamblaje del ADN y las proteínas en partículas víricas maduras. Inhibe la iniciación de la síntesis de ARN al unirse a la subunidad β de la ARN polimerasa, lo que provoca la muerte celular.
