Application in the Pharmaceutical Industry: Tetrahydrozoline has several important applications in the pharmaceutical industry. It is primarily used as a nasal decongestant to relieve symptoms associated with the common cold, allergies, and sinusitis. When applied topically, it constricts the blood vessels in the nasal passages, reducing swelling and congestion.

Tetrahydrozoline is also widely used as an ocular lubricant and redness reliever. It is commonly found in over-the-counter eye drops, which provide temporary relief from eye redness caused by minor irritations, such as dust, smoke, or dryness. By constricting the blood vessels in the eyes, Tetrahydrozoline reduces redness and provides soothing relief.

Furthermore, Tetrahydrozoline is sometimes used in combination with other active ingredients to treat eye conditions such as allergic conjunctivitis, eye allergies, and eye irritation caused by contact lenses. These formulations provide a multi-symptom relief approach, targeting redness, itching, and watering of the eyes.
