How is Pazeo primarily administered?

Pazeo is primarily administered topically in the eye because it is an eye drop formulation used to relieve allergic conjunctivitis symptoms such as itchy eyes. The active ingredient in Pazeo, which is olopatadine hydrochloride, works directly on the eye tissues, providing quick relief by targeting the histamine receptors involved in the allergic response. This route of administration is particularly effective for localized treatment, allowing for higher concentrations of the medication at the site of action while minimizing systemic side effects. Other methods of administration, such as orally or intravenously, are not suitable for this specific type of medication, and inhalation is not relevant as it targets the respiratory system rather than the ocular area.
