Aspirin is NOT used therapeutically as what?

Aspirin is primarily known for its analgesic (pain-relieving), antipyretic (fever-reducing), and anti-inflammatory properties. It works by inhibiting the enzyme cyclooxygenase (COX), which plays a crucial role in the formation of prostaglandins, compounds that mediate pain, fever, and inflammation. Therefore, it effectively reduces pain, lowers fever, and alleviates inflammation.

In contrast, aspirin is not used therapeutically as a decongestant. Decongestants are medications that relieve nasal congestion, typically by constricting blood vessels in the nasal passages, which reduces swelling and mucus production. Common decongestants include substances like pseudoephedrine and phenylephrine that work through mechanisms distinct from aspirin's action. Aspirin does not address nasal congestion or the underlying causes associated with conditions like colds or allergies, which is why it is not classified or used as a decongestant.
