Know a little about “medicine” | What are the advantages of nitroglycerin aerosol in treating angina pectoris?

Aunt Wang suffered from angina pectoris 3 months ago. During the follow-up visit, the doctor prescribed nitroglycerin aerosol. She asked the pharmacist whether the nitroglycerin she had taken before was a tablet to be taken orally, and whether this aerosol spray would also work?

The fastest onset time of nitroglycerin is 30 seconds to 1 minute after taking the medicine. The commonly used nitroglycerin dosage forms in clinical practice are injections, tablets and aerosols. Tablets and aerosols can be stored at home for use in the prevention and treatment of angina pectoris, and are particularly suitable for first aid during angina attacks. Aerosols are more and more widely used in clinical practice because they are easy to use and have a significantly faster onset time than tablets. Nitroglycerin aerosol can be used when angina pectoris attacks or there are signs of angina attacks. When using, immediately remove the cap of the aerosol, shake it well, aim the nozzle at the patient's oral sublingual mucosa and spray 1-2 presses. It should be noted that vasodilatory headaches, facial flushing, dry mouth, dizziness, etc. may occur in the early stage of medication. Therefore, patients should take a sitting or semi-recumbent position when taking the medicine, and change their position slowly after use to prevent fainting and falling.
