Learn why transudative fluid does not contain proteins, why exudate does contain proteins, and how health professionals can differentiate between the two using Lightâs criteria.
Chemistry [edit]. Betahistine chemically is 2-[2-(methylamino)ethyl]pyridine, and is formulated as the dihydrochloride salt. Its structure closely resembles that of phenethylamine and histamine.t is rapidly and completely absorbed. The mean plasma half-life is 3â4 hours, and excretion is virtually complete in the urine within 24 hours. Plasma protein binding is very low. Betahistine is transformed into aminoethylpyridine and hydroxyethylpyridine and excreted with the urine as pyridylacetic acid.
