What is the difference between loratadine and desloratadine?
Loratadine and desloratadine are both anti-allergy antihistamines and act in the same way, preventing the action of histamine, which is the substance that causes allergy symptoms.
However, they have some differences. Desloratadine is obtained from loratadine, resulting in a drug that has a longer action time, which means that it stays in the body longer, and in addition its structure has less ability to cross the brain and cause drowsiness.
