What's the best time of year to start building? If you live in a climate that has hot summers and cold snowy winters (we're in Northeast Pennsylvania). I'm not sure if we should shoot for this fall, or should we wait until next spring? I'd appreciate your thoughts/experiences.
Topics | Pharmacology | Cardiovascular Agent | How does nitroglycerin treat high blood pressure? High blood pressure (hypertension) happens when your blood has a hard time getting through the body, usually because of narrowed arteries. Nitroglycerin is a vasodilator. This means it widens the arteries so your blood can more freely move through them, your heart does not have to work so hard, and this lowers your blood pressure.

Nitroglycerin preferentially vasodilates the coronary arteries, but other arteries in the body also dilate. When this happens to the cerebral arteries that supply blood to the brain, a headache can result.
