A polymorphic form of 5-[4-[2-(N-methyl-N-(2-pyridyl)amino)ethoxy]benzyl]thiazolidine-2,4-di one, maleic acid salt (the "Polymorph") characterised in that it: (i) provides an infra red spectrum containing peaks at 1360, 1326, 1241, 714 and 669 cm<-1>; and/or (ii) provides a Raman spectrum containing peaks at 1581, 768, 670, 271 and 226 cm<-1>; and/or (iii) provides a solid-state nuclear magnetic resonance spectrum containing peaks at chemical shifts substantially as set out in Table I; and/or (iv) provides an X-ray powder diffraction (XRPD) pattern containing peaks substantially as set out in Table II; a process for preparing such a compound, a pharmaceutical composition containing such a compound and the use of such a compound in medicine.
