How Do You Spell CLASSICAL ANTIHISTAMINICS?

1. Classical antihistaminics, also known as traditional or first-generation antihistamines, are a class of drugs that target the effects of histamine, a substance produced by the body in response to allergic or inflammatory reactions.

However, they are still widely used in the treatment of allergies and allergic reactions, as they can provide effective relief for many individuals.

They are available over-the-counter in many forms, including tablets, capsules, and syrups. However, it is essential to follow dosage instructions carefully and consult a healthcare professional if symptoms persist or worsen.

   In summary, classical antihistaminics are a class of drugs that aim to alleviate symptoms caused by histamine release during allergic reactions. While they have been largely replaced by newer, second-generation antihistamines due to their side effect profile, they still play a
