n. a drug that differs in minor ways in molecular structure from its parent compound. Examples are calcipotriol (an analogue of vitamin D), betahistine (an analogue of histamine), and the gonadorelin analogues. Useful analogues of existing drugs are either more potent or cause fewer side-effects. Carboplatin and oxaliplatin, for example, are less toxic analogues of cisplatin.
