This document discusses the manufacturing process for fexofenadine hydrochloride through 10 stages including routes of synthesis, material balance, and environmental impact reports. It also provides information on consultants that can assist with EIA reports, and details on patents, certificates of analysis, material safety data sheets, technology sourcing, academic theses, major manufacturers, and market scenario for fexofenadine hydrochloride production. Additionally, it notes that fexofenadine is less sedating than cetirizine and is considered the best antihistamine choice for those in safety-critical jobs.

10. Cetirizine is significantly more
likely than fexofenadine to cause
drowsiness. Fexofenadine
(Allegra), even in dosages
exceeding those recommended,
is the least sedating of all second-
generation antihistamines, so is
considered the antihistamine of
choice for people in safety-critical
jobs such as airline pilots.
