Novel salts of omeprazole with Li+ Na+ K+ Mg2+ Ca2+ Ti4+ N+(R1)4 or as cation; processes for their preparation thereof pharmaceutical compositions containing such salts and their use in medicine.

Novel compounds of the formula wherein R is H or CH3 a process for their preparation and their use as intermediates in the preparation of pharmaceutically useful compounds e.g. substituted benzimidazoles containing a pyridine radical i.a. omeprazole.

The present invention relates to novel compounds of the formula wherein R1 and R2 are the same or different and are each hydrogen, alkyl, halogen, carbomethoxy, carbethoxy, alkoxy, or alkanoyl, R6 is hydrogen, methyl or ethyl, R3, R4 and R5 are the same or different and are each hydrogen, methyl, methoxy, ethoxy, methoxyethoxy or ethoxyethoxy whereby R3, R4 and R5 are not all hydrogen, and whereby when two of R3, R4 and R5 are hydrogen the third of R3, R4 and R5 is not methyl. The compou...
