ANTIALLERGIC DRUGS Meaning and
Definition
-
Antiallergic drugs, also known as antihistamines or allergy medications, refer to a class of medications that are designed to alleviate or alleviate symptoms associated with an allergic reaction. Allergies occur when the immune system overreacts to usually harmless substances, such as pollen, dust mites, pet dander, or certain foods, triggering an allergic response. Antiallergic drugs work by blocking the effects of histamine, a chemical released by the body during an allergic reaction.
Histamine is responsible for various allergic symptoms like itching, sneezing, runny nose, watery eyes, and skin rashes. By interfering with the action of histamine, antiallergic drugs can help reduce or relieve these symptoms. These medications are available in various forms, including oral tablets, liquids, nasal sprays, eye drops, and creams.
Antiallergic drugs can be classified into two main categories: first-generation antihistamines and second-generation antihistamines. First-generation antihistamines, such as diphenhydramine and chlorpheniramine, are often associated with drowsiness and are commonly used for short-term relief of allergy symptoms. Second-generation antihistamines, such as cetirizine and loratadine, are generally non-drowsy and provide longer-lasting relief, making them more suitable for long-term use.
It is important to note that antiallergic drugs only relieve the symptoms of allergies and do not cure or prevent the underlying allergic response. Therefore, it is advisable to identify and avoid allergens whenever possible, in addition to using antiallergic medications, to effectively manage allergies.

Etymology of ANTIALLERGIC DRUGS
The word "antiallergic" is derived from three roots:
1. "Anti-" is a prefix derived from the Greek word "anti", meaning "against" or "opposite". It is commonly used to indicate opposition or negation.
2. "Allerg(y)" is derived from the Greek word "allos", meaning "other or different", and "ergon", meaning "work or activity". It was coined by the Austrian pediatrician Clemens von Pirquet in 1906 to describe hypersensitivity reactions.
3. "-ic" is a suffix that is added to the end of a word to denote "relating to" or "pertaining to".
The word "drug" comes from the Old French word "drogue" meaning "medicine" or "substance used in medication".
