H 1 receptor blocker
This is an antiallergic drug, mainly used for allergic rhinitis.
Antibiotics have antibacterial or bactericidal effects. Different from the role of kestin, kestin destroys the sensitization process by blocking H 1 receptor. Antibiotics kill or inhibit bacteria and viruses by destroying their structures and metabolic processes, thus eliminating infection and inflammation.
Simply put, one is to treat allergies.
One is antibacterial.
