Introdução: O que é Melfalano?

O melfalano é um medicamento quimioterápico usado principalmente para tratar certos tipos de câncer, incluindo mieloma múltiplo e câncer de ovário. Pertence a uma classe de medicamentos conhecidos como agentes alquilantes, que atuam interferindo no DNA das células cancerígenas, impedindo sua divisão e crescimento.

Melphalan works by attaching to the DNA of cancer cells, causing crosslinking that prevents the cells from replicating.
