**For the treatment and prophylaxis of angina pectoris and the treatment of variant angina diagnosed by your Doctor.**
Nitrolingual is a sublingual spray which means that you use it under your tongue. The active ingredient is called glyceryl trinitrate or GTN for short. GTN is one of a group of medicines called ‘nitrates’. These relax the muscles around the blood vessels and make it easier for the heart to do its work. Nitrolingual helps stop the pain of angina (pain in your chest, arms or neck especially when you exert yourself). You can also use the medicine immediately before doing things which you know will cause you angina pain.
