The present invention provides pharmaceutical formulations suitable for intravenous injection comprising a lyophilized anti-ulcerative agent reconstituted in isotonic solutions suitable for intravenous administration, such as 5% dextrose or 0.9% sodium chloride. The solutions are brought to a pH of between about 9 and about 12, preferably between about pH 10 and 11, by a glycine-sodium hydroxide buffer. Such formulations are chemically and physically stable, and do not significantly change color, for at least between about 6 and about 12 hours at room temperature, and are stable to color change for from between about 24 and 48 hours if kept at 5° C.
