Quifenadine
Quifenadine is a non-sedating antihistamine used in the treatment of allergic rhinitis, urticaria and other allergic conditions. It is a third-generation antihistamine, meaning it is less likely to cause drowsiness or impair psychomotor function compared to older antihistamines.
Pharmacology[edit | edit source]
Quifenadine works by blocking the action of histamine, a substance in the body that causes allergic symptoms. It does this by binding to and blocking the H1 receptor, one of the four known types of histamine receptors in the human body. This prevents histamine from having an effect, thus reducing symptoms of allergy.
Uses[edit | edit source]
Quifenadine is used to treat a variety of allergic conditions, including:
- Allergic rhinitis: This is an allergic reaction to allergens such as pollen, dust mites or pet dander, which causes symptoms such as sneezing, runny nose, and itchy or watery eyes.
- Urticaria: Also known as hives, this is a skin reaction that causes red, itchy bumps to appear on the skin.
- Other allergic conditions: Quifenadine may also be used to treat other conditions where histamine is involved, such as angioedema (swelling beneath the skin) or certain types of dermatitis (skin inflammation).
