how long does it take for loratidine to work
Loratadine Loratadine's peak effect occurs after one to two hours, and its biological half-life is on average 8 hours (range 3 to 20 hours) with desloratadine's half-life being 27 hours (range 9 to 92 hours), accounting for its long-lasting effect.[19] About 40% is excreted as conjugated metabolites into the urine, and a similar amount is excreted into the feces. Traces of unmetabolised loratadine can be found in the urine.[8]
Hydrochloride Converting insoluble amines into hydrochlorides is a common way to make them water-soluble. This characteristic is particularly desirable for substances used in medications.[1] The European Pharmacopoeia lists more than 200 hydrochlorides as active ingredients in medications.[2] These hydrochlorides, compared to free bases, may more readily dissolve in the gastrointestinal tract and be able to be absorbed into the bloodstream more quickly. In addition, many hydrochlorides of amines have a longer shelf-life than their respective free bases
