The effect of Nitromint sublingual tablet and Nitromint aerosol (EGIS) has been studied in ambulance practice. Both drug forms relieved or controlled the complaints and symptoms, and proved to be effective in a great number of cases. Due to it's easier storage and easier applicability the aerosol is more advantageous than the sublingual tablet. Occasionally the simultaneous use of the two products is also beneficial. Supposedly the indication field of nitroglycerin will be extended in the near future and Nitromint preparations will be used in oxyology also for controlling other clinical conditions in which smooth muscle spasm has a major role.
