A pharmaceutical composition is disclosed. In at least one embodiment, a pharmaceutical drug is linked via a peptide linker to an iron-binding agent, for example an iron-binding protein, with the iron-binding agent in turn being bound to an iron-containing magnetic particle. The peptide linker has a protease recognition sequence, i.e. it may be cleaved at said protease recognition sequence by a protease, thereby enabling the pharmaceutical drug to be released locally. The pharmaceutical composition is suitable for magnetic drug targeting.
