A compound, or a solvate or salt thereof, of formula (I):
in which:
RCO is an acyl group in which the group R contains a substituted or unsubstituted carbocyclic aromatic or heterocyclic aromatic ring;
R₁ and R₂ are independently hydrogen, C₁₋₆ alkyl, C₂₋₆ alkenyl, C₃₋₆ cycloalkyl or C₄₋₁₂ cycloalkylalkyl groups, or together form a C₂₋₈ branched or linear polymethylene or C₂₋₆ alkenylene group, optionally substituted with a hetero-atom,
R₃ is hydrogen , C₁₋₆ alkyl or phenyl, or R₃ together with R₁ form a -(CH₂)₃- or -(CH₂)₄- group;
R₄ and R₅ are independently hydrogen, hydroxyl, halogen, C₁₋₆ alkyl or aryl, provided both R₄ and R₅ are not simultaneously hydrogen; and p is an integer from 1 to 4,
is useful for the treatment of pain or hyponatraemic disease states.
