Oftan Metaoksedrin (Phenylephrine Hydrochloride)

Phenylephrine hydrochloride is a selective alpha‑1 adrenergic agonist. When applied to the eye, it activates alpha‑1 receptors on the smooth muscle of conjunctival blood vessels and the iris dilator muscle, causing vasoconstriction that reduces redness and contraction of the dilator muscle that produces pupil dilation. The action is localized to the ocular surface.

The specific dose and frequency of Oftan Metaoksedrin are determined by the prescribing eye care professional based on the indication, patient age, and clinical response. Typical ophthalmic administration involves a few drops instilled into the affected eye(s) as directed, but the exact regimen should always follow the prescriber’s instructions.

Safety data for phenylephrine hydrochloride ophthalmic use in pregnancy or lactation are limited. The product should be used only if the potential benefit justifies any potential risk to the fetus or infant. Healthcare providers should evaluate the individual situation and discuss possible alternatives when treating pregnant or nursing patients.

Phenylephrine is a sympathomimetic mydriatic that primarily induces pupil dilation through alpha‑1 mediated iris muscle contraction, whereas agents like tropicamide act on muscarinic receptors to produce a faster but shorter‑lasting effect. Phenylephrine may provide a more sustained dilation but can raise systemic blood pressure, making patient selection and monitoring important when choosing between agents.

The product should be stored at room temperature, preferably below 25 °C, in its original container. Protect the solution from direct light and moisture, and keep the cap tightly closed when not in use. Do not freeze the product, and discard any solution that appears discolored or contains particles.

Oftan Metaoksedrin is applied topically to the eye. The recommended technique is to wash hands, tilt the head back, gently pull down the lower eyelid, and instill the prescribed number of drops into the conjunctival sac. Avoid touching the dropper tip to the eye or any surface to maintain sterility.

Serious risks include a significant rise in intra‑ocular pressure, which can exacerbate glaucoma, and systemic hypertension or cardiovascular stimulation, especially in patients with pre‑existing heart disease. Rarely, severe allergic reactions or corneal edema may occur. Prompt medical evaluation is required if any of these symptoms develop.

Contraindications include patients with narrow‑angle or acute angle‑closure glaucoma, uncontrolled hypertension, known hypersensitivity to phenylephrine or any excipients, and individuals using monoamine oxidase inhibitors. Use should be avoided or carefully monitored in patients with cardiovascular disease, severe systemic illness, or those taking interacting medications.
