Astelin (Azelastine) is an antihistamine drug that works by reducing the effects of histamine chemical secreted in the body.

Physiology behind Astelin nasal sprays action

Astelin is an anti-allergic drug that works by inhibiting signs of the allergic rhinitis. The duration of effect after drug inoculation is usually 2 to 3 hours and reaches its peak action after 5hours. The effect of a single dosage operates to a maximum of 12 hours. Astelin is a quick acting drug which works on same receptors such as histamine. When taken, Azelastine HCl produces antihistamine which stabilizes the membranes of the nasal cavity.

Astelins pharmacological action inhibits the release of mediators which could have otherwise produced symptoms such as sneezing. Azelastine also reduces the speed at which the immune system responds to the introduction of allergens. Serotonin, leukotrienes, and histamine secretions are regulated during an allergy hence thereby lessen the permeability of capillaries. The action prevents the release of such chemicals that would have otherwise initiated the onset of severe symptoms.

Precautions to take

Children below six years of age should not use Astelin. Children younger than this age are advised to use other drugs to relieve allergic symptoms. Pregnant and lactating women should not use Astelin. There are possible chances of traces of the compound reaching the infant or fetus as the drug dissolves fast in a semipermeable membrane. The use is strongly opposed especially during the first term of pregnancy.

Administer the drug while the head is straight. The drug has the capability of reaching the throat and can cause an irritable bitter taste. Sometimes reactions occur in some patients increasing the effect of the allergic reaction. In such occurrences, one should stop using the drug.
