what would make your body resistant to nitro?

Answer 1

The effectiveness of nitroglycerine to treat angina can lessen over time with repeated or constant use. Patients that use a skin patch recieve a constant low dose to try to keep the coronary arteries and veins dialated. In some people, eventually the arterial walls seem to get used to the drug stimulation and quit reacting to it. Sometimes the situation improves by not taking it for a day or so, and sometimes it doesn't. Vitamin C seems to help avoid the problem developing, but thats about the only thing that seems to have an effect. People who use Nitro tablets or patches should be re-evaluating the effectiveness of it with their doctor on a regular basis, say every 3-4 months, if they are using it on a regular or daily basis. The other common reason for the tablets not to work effectively usually has to do with a physical breakdown of the tablets due to heat or light exposure, or even just age. Nitroglycerine tablets can breakdown and become basically sugar pills if they are not stored correctly, and would not have the dosage you were expecting to get- so they wouldn't work like they should.
