Imidazyl (Naphazoline Nitrate)

Naphazoline Nitrate is a selective alpha‑adrenergic receptor agonist. When applied to the eye, it binds to alpha receptors on conjunctival vessels, causing vasoconstriction. This reduces blood flow to the ocular surface, decreasing capillary dilation, redness, and associated swelling.

The appropriate dosing regimen for Imidazyl is determined by the prescribing healthcare professional. Typically, one or two drops are instilled in the affected eye(s) up to three to four times per day, but the exact frequency and duration should follow the prescriber’s instructions.

Safety data for Naphazoline Nitrate in pregnancy and lactation are limited. It should only be used if the potential benefit justifies the potential risk to the fetus or infant, and the decision should be made by a qualified healthcare provider.

To order Imidazyl, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies, and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details, and any necessary import documentation.

Both Imidazyl (naphazoline nitrate) and tetrahydrozoline are alpha‑adrenergic agonists that reduce eye redness through vasoconstriction. Naphazoline generally has a slightly faster onset, while tetrahydrozoline may have a longer duration of action. Choice of product depends on clinician preference, patient response, and formulation availability.

Imidazyl should be stored at room temperature, away from direct sunlight and moisture. Keep the bottle tightly closed when not in use and retain it in its original packaging to protect the formulation from contamination.

Imidazyl is administered topically as eye drops. The patient should wash hands, tilt the head back, pull down the lower eyelid, and place the prescribed number of drops into the conjunctival sac. Avoid touching the tip of the bottle to the eye or any surface.

Serious risks include a rise in intra‑ocular pressure, especially in patients with narrow‑angle glaucoma, and rare allergic reactions that may cause swelling, rash, or breathing difficulties. Persistent eye pain or vision changes should prompt immediate medical evaluation.

Imidazyl should not be used by individuals with known hypersensitivity to naphazoline nitrate or any excipients, and it is contraindicated in eyes with narrow‑angle glaucoma, severe ocular infection, or ulceration. Patients with these conditions should consult a healthcare professional for alternative therapy.
