Mechanism of action
The mechanism of action of tetrahydrozoline ophthalmic involves the constriction of blood vessels in the eyes, reducing the flow of blood to the affected area. This leads to a reduction in the redness and swelling associated with allergic reactions or other irritants. The drug achieves this effect by binding to alpha-2 adrenergic receptors, which are present in the smooth muscle cells of blood vessels
The spectrum of activity of tetrahydrozoline ophthalmic is limited to the eyes and the surrounding tissues. It is ineffective in treating conditions that affect other body parts
