fexofenadine profile

Fexofenadine is a non-sedating antihistamine used to treat allergies. It is a second-generation antihistamine, meaning it is less likely to cause drowsiness than older antihistamines. Fexofenadine is a selective antagonist of the H1 receptor, which means it blocks the action of histamine at this receptor. Histamine is a chemical that is released by the body in response to allergens. When histamine binds to the H1 receptor, it causes a variety of allergic symptoms, such as sneezing, runny nose, itchy eyes, and hives. Fexofenadine blocks histamine from binding to the H1 receptor, which prevents these symptoms from occurring. Fexofenadine is available in both prescription and over-the-counter formulations. It is typically taken once or twice a day. Fexofenadine is generally well-tolerated, but it can cause side effects such as headache, drowsiness, and nausea. Fexofenadine was synthesized by scientists at Hoechst AG in the early 1990s. It was approved for use in the United States in 1996. Fexofenadine is a popular antihistamine because it is effective in treating allergies and is relatively safe for most people. It is studied to better understand its effects on the human body and to develop new and improved antihistamines.'

Effects

Fexofenadine has a positive antihistamine effect, which is probably no worse than the second-generation antihistamines. It is also well tolerated in subjects with renal or hepatic impairment, in children and the elderly.

Fexofenadine (FEX) has a positive antihistamine effect, which is probably no worse than the second-generation antihistamines. It has been used for its efficacy and safety in the treatment of allergic rhinitis (AR) for many years although no meta-analyses supporting its use currently exist. FexofENadine has also been shown to have a favorable effect on nasal congestion.

Dosage Studied

Fexofenadine HCl (Allegra, Telfast) is approved in the US for twice-daily dosing for treatment of seasonal allergic rhinitis. Although widely used in the treatment of allergic diseases, fexofen adine is not listed in any pharmacopeia. There are few methods in the literature for its quantitation in pharmaceutical dosage forms.
