Indications & Clinical Uses

  • Mydrane is used in ophthalmic procedures that require both anesthesia and pupil dilation.\n\nCataract surgery: provides effective pupil dilation and intraocular anesthesia to enable safe lens removal.\nIntraocular surgery (e.g., vitrectomy): facilitates mydriasis and analgesia for better surgical access.\nOther ophthalmic procedures: supports surgical exposure by dilating the pupil and delivering local anesthesia.

How It Works

  • Mydrane combines three agents that act on distinct ocular targets. Lidocaine blocks voltage‑gated sodium channels in corneal and intraocular nerves, producing rapid local anesthesia. Phenylephrine stimulates alpha‑1 adrenergic receptors on the iris dilator muscle, causing contraction and pupil dilation. Tropicamide antagonizes muscarinic receptors in the iris sphincter and ciliary body, leading to cycloplegia and additional mydriasis. The synergistic action yields prompt anesthesia and sustained pupil dilation for intraocular surgery.

Side Effects

  • Mydrane may cause a range of ocular and systemic reactions.\n\nCommon Side Effects:\n- Ocular discomfort or burning sensation\n- Transient increase in intra‑ocular pressure\n- Mild conjunctival hyperemia\n- Temporary blurred vision\n- Mild corneal edema\n- Light‑headedness or mild headache\n\nSerious or Rare Side Effects:\n- Severe allergic reaction (anaphylaxis)\n- Persistent mydriasis lasting >24 hours\n- Sustained intra‑ocular pressure elevation\n- Corneal ulceration or keratitis\n- Endophthalmitis\n- Retinal toxicity

Precautions & Warnings

  • Before using Mydrane, clinicians should consider several safety measures.\n\nPatient assessment: evaluate ocular health and allergy history.\nContraindications: avoid in patients with known hypersensitivity to lidocaine, phenylephrine, or tropicamide.\nIntra‑ocular pressure monitoring: check IOP before and after administration.\nCardiovascular caution: phenylephrine may raise systemic blood pressure; monitor hypertensive patients.\nPregnancy and lactation: limited data; use only if benefit outweighs risk.\nStore at ambient temperature: keep in original container, protect from light and moisture.

Avoid Interactions

  • Mydrane can interact with other medications that affect ocular or systemic physiology.\n\nMajor Interactions (Avoid):\n- Systemic alpha‑agonists (e.g., phenylephrine nasal spray) may cause additive hypertensive effects.\n- Monoamine oxidase inhibitors can potentiate phenylephrine‑induced blood pressure rise.\n- Concurrent use of other local anesthetics may increase risk of toxicity.\n\nModerate Interactions (Monitor Closely):\n- Topical non‑steroidal anti‑inflammatory drugs may delay corneal healing.\n- Systemic antihypertensives may blunt phenylephrine‑mediated pupil dilation.

Frequently Asked Questions

Mydrane is an intracameral ophthalmic solution used to provide local anesthesia and to dilate the pupil during intraocular procedures such as cataract extraction, vitrectomy, and other eye surgeries that require a clear surgical field.

Lidocaine blocks sodium channels in ocular nerves, producing rapid anesthesia. Phenylephrine activates alpha‑1 receptors on the iris dilator muscle, causing contraction and pupil enlargement. Tropicamide blocks muscarinic receptors in the iris sphincter and ciliary body, leading to cycloplegia and additional mydriasis. Together they deliver both analgesia and sustained dilation.

The dose of Mydrane is determined by the operating ophthalmologist based on the specific surgical procedure and patient characteristics. It is administered intracamerally in a single dose at the start of the operation.

Safety data for Mydrane in pregnancy and lactation are limited. It should only be used when the potential benefit to the mother outweighs any possible risk to the fetus or infant, and the decision should be made by the prescribing clinician.

To order Mydrane, 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 (including any cold‑chain requirements), and necessary import documentation.

Mydrane combines a local anesthetic (lidocaine) with two mydriatic agents (phenylephrine and tropicamide) in a single intracameral formulation, offering simultaneous anesthesia and pupil dilation. Alternative regimens often require separate administration of anesthetic and dilating drops, which can prolong preparation time and increase handling steps.

Mydrane should be stored at ambient temperature, below 25 °C, in its original sealed container. Protect the vial from direct light and moisture. Do not freeze or shake the solution before use.

Mydrane is administered by the surgeon directly into the anterior chamber of the eye (intracameral injection) at the beginning of the procedure. The injection is performed under sterile conditions using a calibrated syringe.

Serious risks include severe allergic reactions such as anaphylaxis, persistent mydriasis lasting more than 24 hours, sustained elevation of intra‑ocular pressure, corneal ulceration, endophthalmitis, and retinal toxicity. Prompt recognition and appropriate management are essential.

Mydrane is contraindicated in patients with known hypersensitivity to lidocaine, phenylephrine, tropicamide, or any component of the formulation. Caution is advised in patients with uncontrolled hypertension, severe cardiovascular disease, or active ocular infections.
