Pharmacokinetics

One major distinguishing feature among alkylating agents is the rate at which the parent drug is converted to a strong electrophile. For some drugs (e.g. MECHLORETHAMINE), the reaction is virtually instantaneous --- these agents are given IV to minimize blistering and GI effects. Other agents (such as CYCLOPHOSPHAMIDE, BUSULFAN, and MELPHALAN) must be activated in various tissues, and they can be given orally.
