Final answer:
Antihistamines like Loratadine are used to treat symptoms of allergies. Pseudoephedrine is a decongestant often combined with antihistamines, while Phenylephrine helps clear nasal congestion by dilating bronchioles.
Explanation:
Antihistamines such as Loratadine (Claritin) are typically used to treat symptoms like runny nose, sneezing, and sore throat associated with allergies or colds. Antihistamines work by reducing or eliminating the effects of histamines that cause these symptoms.
Pseudoephedrine (Sudafed) is commonly used as a nasal decongestant and can be found in combination with other medications like antihistamines in cold and allergy preparations to relieve congestion.
Phenylephrine is another decongestant that can help with nasal congestion by dilating the bronchioles in the lungs, allowing mucus to be cleared.
