The present invention relates to a selective inhibitor of mammalian osteoclast cell activity, processes for its preparation and pharmaceutical compositions comprising the same as well as methods of treatment, where said selective inhibitor is administered to a human or animal patient. Said selective inhibitor has been found to inhibit vacuolar H+-ATPase, such as vacuolar H-ATPase in osteoclast cells, whereby it is therapeutically efficient against physiological disorders involving bone resorption. In an embodiment of the present invention, said selective inhibitor comprises a nicotinonitrile compound with general formula (I). |
