Which term describes a medication that alleviates itching?

The term that describes a medication specifically designed to alleviate itching is "antipruritic." Antipruritic medications work by targeting the underlying causes of itchiness, which can be the result of various irritations, allergic reactions, or skin conditions. They can provide relief through different mechanisms, such as blocking histamine receptors or reducing inflammation, ultimately helping to soothe the discomfort associated with itching.

Antipyretics are medications that reduce fever, not itching. Antihistamines can manage symptoms associated with allergic reactions, including some forms of itching, but they are not exclusively focused on this symptom. Antibiotics are used to treat bacterial infections and do not have a direct effect on itching. Thus, antipruritic is the most relevant term in this context for medications aimed at relieving itchiness.
