CLASSICAL ANTIHISTAMINES Meaning and Definition

1. Classical antihistamines refer to a class of drugs that are primarily used to treat allergies, specifically to relieve symptoms associated with histamine release in the body. Histamine is a chemical compound that is released by the immune system when the body is exposed to allergens, such as pet dander, pollen, or certain foods. These antihistamines work by blocking the effects of histamine, preventing it from binding to histamine receptors and thus reducing the symptoms caused by its release.

   Classical antihistamines are often characterized by their sedating side effects, which can cause drowsiness and impair cognitive function. These drugs are typically effective in alleviating symptoms such as itching, sneezing, runny nose, watery eyes, and hives caused by histamine release. They are typically available over-the-counter and are frequently used to manage seasonal allergies, hay fever, and allergic rhinitis.

   Examples of classical antihistamines include diphenhydramine (Benadryl), chlorpheniramine (Chlor-Trimeton), and promethazine (Phenergan). These drugs are known to have a relatively short duration of action, usually requiring multiple daily doses to maintain their effects.

   It is important to note that the sedating nature of classical antihistamines can be undesirable for some individuals, especially those who need to remain alert and focused, such as while operating machinery or driving. Therefore, non-sedating antihistamines, such as loratadine (Claritin) and cetirizine (Zyrtec), are often preferred for daytime use.

Etymology of CLASSICAL ANTIHISTAMINES

The word "classical antihistamines" is a term used in pharmacology and medicine to describe a specific category of antihistamine drugs.

The etymology of the term can be traced back to two main components: "classical" and "antihistamines".

1. "Classical" derives from the Latin word "classicus", which means "of the highest class" or "of the first rank". In the context of pharmacology, "classical" is used to refer to older or first-generation drugs that were among the first to be discovered and used in the treatment of allergies and allergic reactions.

2. "Antihistamines" are drugs that block or inhibit the effects of histamine, a chemical substance released by cells in response to an allergic reaction.
