Trocane Eye Drop 0.8%+5% contains a combination of Tropicamide 0.8% and Phenylephrine Hydrochloride 5%, formulated to facilitate pupil dilation (mydriasis) and temporary paralysis of the ciliary muscles (cycloplegia) during ophthalmic examinations. This combination is commonly used by ophthalmologists for diagnostic procedures such as fundoscopy, retinoscopy, and intraocular pressure measurement, allowing a detailed view of the retina and other internal structures of the eye.

Trocane Eye Drop provides rapid onset of action and effective pupil dilation while maintaining a safe profile for use in adults and children under medical supervision. The synergistic action of its components ensures both dilation and improved visualization of ocular structures for precise clinical assessment.

Composition

• Tropicamide 0.8% – a muscarinic receptor antagonist causing temporary paralysis of the ciliary muscles (cycloplegia)

• Phenylephrine Hydrochloride 5% – an alpha-adrenergic agonist causing pupil dilation (mydriasis)

Mechanism of Action

1. Tropicamide – Blocks muscarinic receptors in the iris sphincter and ciliary muscles, preventing constriction of the pupil and temporarily paralyzing accommodation. This allows ophthalmologists to examine the retina and lens clearly without interference from pupil movement.

2. Phenylephrine Hydrochloride – Stimulates alpha-adrenergic receptors in the iris dilator muscle, causing contraction and further dilation of the pupil. It also reduces conjunctival redness and improves visualization of intraocular structures.

3. Combined effect – Tropicamide and Phenylephrine work together to achieve faster and more effective pupil dilation with minimal systemic absorption, enhancing the safety and efficacy of diagnostic procedures.

Indications

Trocane Eye Drop 0.8%+5% is indicated for:

• Diagnostic ophthalmic procedures – including fundus examination, retinoscopy, and tonometry

• Cycloplegic refraction – to accurately determine refractive errors in children and adults

• Pre-surgical pupil dilation – before certain eye surgeries to improve surgical access and visibility

• Management of uveitis or anterior segment inflammation – under supervision, to relieve ciliary spasm and pain

Dosage and Administration

• Instill 1–2 drops in the affected eye(s) as directed by an ophthalmologist.

• Allow 15–30 minutes for full effect before performing the examination.

• Avoid touching the dropper tip to the eye or eyelids to prevent contamination.

• Remove contact lenses before administration and wait at least 15 minutes before reinsertion.

• Monitor for systemic effects, particularly in children, elderly patients, or those with cardiovascular conditions.

Benefits

• Provides rapid and effective pupil dilation for diagnostic and surgical procedures

• Facilitates accurate retinal examination and refractive assessment

• Reduces ciliary muscle spasm and discomfort during ocular procedures

• Combines two agents for a synergistic effect, improving efficacy and reducing required dosing

• Safe and well-tolerated when used under medical supervision

Precautions

• Avoid use in patients with narrow-angle glaucoma unless under strict supervision.

• Use caution in patients with cardiovascular disorders, hypertension, hyperthyroidism, or diabetes.

• Avoid driving or operating machinery until full visual recovery, as dilation may cause blurred vision and photophobia.

• Contact a physician if excessive eye irritation, pain, or allergic reaction occurs.

• Not recommended for prolonged use; intended for diagnostic or preoperative purposes only

Possible Side Effects

Common side effects may include:

• Temporary blurred vision or difficulty focusing

• Sensitivity to light (photophobia)

• Mild stinging or burning upon instillation

Rare but serious side effects:

• Increased intraocular pressure, particularly in glaucoma patients

• Systemic cardiovascular effects, including elevated blood pressure or palpitations

• Allergic reactions such as itching, swelling, or rash

Storage

• Store below 25°C in a cool, dry place

• Protect from light

• Keep the bottle tightly closed

• Keep out of reach of children

Trocane Eye Drop 0.8%+5% is a reliable ophthalmic preparation for achieving effective pupil dilation and cycloplegia, ensuring accurate diagnostic examinations and surgical readiness under proper medical supervision.
