Step-by-step explanation:
A decongestant commonly used for cold symptoms is phenylephrine. Phenylephrine is a sympathomimetic drug that binds to adrenergic receptors in the bronchioles of the lungs, causing them to dilate. This dilation helps to clear out accumulated mucus in the lower respiratory tract. Phenylephrine is often combined with other pharmaceuticals in over-the-counter cold medications.
