It plays a vital role in the respiratory tract by allowing air to pass through it while keeping food and drink from blocking the airway.
Common side effects from nicotine gum include bleeding gums, too much saliva, hiccups, indigestion, slight swelling of the mouth, injury to teeth or cheeks, nausea, upset stomach and sore throat.

Nicorandil is another type of blood vessel dilating drug that acts in a slightly different way, and thus can be added to other calcium antagonists to treat angina. As these drugs dilate blood vessels (especially nifedipine and amlodipine), they can cause headaches, flushing of the skin, and ankle swelling. The latter needs to be distinguished from the reduced heart muscle function effects (more so with verapamil and diltiazem)) that can also cause swelling. The heart rate lowering effects can be used to treat some of the arrhythmias such as atrial fibrillation, atrial flutter and SVT.
