Mydrane

Lidocaine Hydrochloride, Phenylephrine Hydrochloride, Tropicamide, the active ingredients in Mydrane, are a combination ophthalmic anesthetic and mydriatic presented as an intracameral solution for intra‑operative use. They provide local anesthesia and pupil dilation during cataract surgery.

GNH USA supplies Mydrane as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals and surgical centres worldwide.

Mydrane is used in ophthalmic procedures to achieve intra‑operative pupil dilation and anesthesia. - Cataract surgery: provides rapid pupil dilation and corneal anesthesia during the procedure. - Intra‑operative ocular examination: facilitates visualization of intra‑ocular structures. - Combined anterior segment surgeries: enables adequate mydriasis and analgesia for procedures such as phacoemulsification.

Mydrane may cause ocular and systemic reactions, which are categorized by frequency.

Common Side Effects: - Transient blurred vision: temporary reduction in visual clarity after administration. - Mild ocular discomfort: brief sensation of irritation or pressure. - Conjunctival hyperemia: mild redness of the eye. - Increased intra‑ocular pressure: temporary rise in eye pressure.

Serious or Rare Side Effects: - Allergic reaction: signs such as swelling, rash, or anaphylaxis. - Persistent mydriasis: prolonged pupil dilation beyond the expected period. - Corneal endothelial toxicity: rare damage to corneal cells. - Endophthalmitis: severe intra‑ocular infection.

Prior to using Mydrane, clinicians should observe the following precautions. - Patient history: verify no known hypersensitivity to lidocaine, phenylephrine, or tropicamide. - Cardiovascular status: avoid in patients with uncontrolled hypertension or severe cardiac disease. - Glaucoma: use cautiously in eyes with narrow angles or uncontrolled glaucoma. - Pregnancy and lactation: safety not established; consider risk‑benefit before use. - Drug interactions: review concomitant ocular or systemic adrenergic agents. - Store at controlled room temperature: keep in original container, protect from light and moisture.

Mydrane can interact with other medications; awareness of these interactions helps prevent adverse outcomes.

Major Interactions (Avoid): - Systemic phenylephrine: may cause excessive hypertension when combined. - MAO inhibitors: increase risk of hypertensive crisis with phenylephrine component. - Other mydriatics: additive pupil dilation leading to prolonged mydriasis.

Moderate Interactions (Monitor Closely): - Beta‑blockers: may blunt cardiovascular response to phenylephrine. - Anticholinergic drugs: may enhance tropicamide effects. - Topical anesthetics: overlapping lidocaine exposure may increase local toxicity.
