Nitroglycerin relaxes the arteries and veins. It pools the blood
in the extremities dropping blood pressure. Chest pain relief can be expected
in 1-3 minutes. Because it is administered sublingually, it is absorbed

should be repeated. It can be repeated the third time( after 5 minutes from
second dose). If the pain doesn't subside after 3 doses, emergency care is
needed.
