Drug of last resort

Common card · No. 333527

A drug of last resort (DoLR), also known as a heroic dose, is a pharmaceutical drug which is tried after all other drug options have failed to produce an adequate response in the patient. Drug resistance, such as antimicrobial resistance or antineoplastic resistance, may make the first-line drug ineffective, especially in case of multidrug-resistant pathogens and tumors. Such an alternative may be outside of extant regulatory requirements or medical best practices, in which case it may be viewed as salvage therapy.
