This invention relates to pharmaceutical compositions comprising compounds of formula
or a pharmaceutically acceptable saltthereofwherein-B-B1- represents a chain of formula
or
or
R represents an optionally substituted aryl or heteroaryl radical,
R', R2, R3 and R4 independently represent hydrogen, or a defined substituent or any adjacent pair of R', R2, R3 and R4 together with the carbon atoms to which they are attached complete a five or six membered saturated or unsaturated carbocyclic or heterocyclic ring, said ring being optionally substituted by a defined substituentand said heterocyclic ring having at least one heteroatom selected from oxygen, nitrogen and sulphur;
R5 and R6 independently represent hydrogen or lower alkyl; n and m independently represent 0 or 1, providing that when -B-B'- has formula la, n is 1 and m is O then R is heteroaryl, the term "heteroaryl" means a monovalent aromatic heterocyclic group in which the ring heteroatom or atoms is/are selected from oxygen, nitrogen and sulphur; and a pharmaceutically acceptable carrier which have anti-uicer and/or anti-secretory activity. Novel compounds of formula I are also disclosed together with processes for preparing them.
