Q

During a cold, the blood vessels that surround the nasal sinus are dilated and engorged with plasma, white blood cells, mast cells, histamines, and many other blood components that are involved in fighting infections of the respiratory tract. This swelling, or dilation, blocks the nasal passages, which results in nasal congestion. When these drugs are administered intranasally, they cause dilated arterioles to constrict, which reduces nasal blood flow and congestion. ______ should be used for no more than 3 days at a time.
