Nicotine causes inflammation in the arteries, which leads to narrowing and hardening of the blood vessels. When blood can't flow freely to your brain, you're at risk for blood clots, stroke and aneurysms. Nicotine also increases your endorphins, brain chemicals that make you feel good.
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.
