Generic Cyclogyl Information

Introduction

Cyclogyl is an ophthalmic solution containing the active compound cyclopentolate. It belongs to the eye‑drop group that acts as a muscarinic antagonist, producing rapid pupil dilation (mydriasis) and temporary paralysis of the ciliary muscle (cycloplegia). In Hong Kong, cyclopentolate eye drops are routinely used by optometrists and ophthalmologists for diagnostic examinations, especially when accurate measurement of refractive error is required. The medication is also employed to facilitate certain therapeutic procedures, such as intra‑ocular lens implantation, and to alleviate ocular discomfort associated with ciliary spasm.

What is Cyclogyl?

• Classification: Cyclogyl is a synthetic anticholinergic eye drop, classified pharmacologically as a muscarinic receptor antagonist.
• Development: Cyclopentolate, the active ingredient, was first synthesized in the 195s and has been approved for ophthalmic use in many regulatory jurisdictions, including the United States, European Union, and Hong Kong.
• Manufacturer: The specific manufacturer of Cyclogyl marketed in Hong Kong is not publicly disclosed; the product is distributed through licensed pharmaceutical importers that comply with the Hong Kong Department of Health’s requirements for ophthalmic preparations.

Cyclogyl is the generic version of well‑known brand‑name cyclopentolate formulations such as Cyclomydril and Mydriacyl. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

How Cyclogyl Works

Cyclogyl’s active compound, cyclopentolate, competitively blocks muscarinic acetylcholine receptors (M₁–M₄) on the iris sphincter and ciliary body. By preventing acetylcholine from activating these receptors, the drug relaxes the smooth muscle of the iris, producing dilation of the pupil, and inhibits the ciliary muscle, halting accommodation.

• Onset: Within 30–45 minutes after instillation, most patients experience noticeable dilation.
• Peak: Maximal effect generally occurs at 60 minutes.
• Duration: The mydriatic and cycloplegic effects persist for 6–24 hours, depending on individual ocular metabolism and the dose administered.
• Clearance: Cyclopentolate is cleared from the ocular tissues primarily via aqueous humor turnover and systemic absorption; systemic half‑life is approximately 2 hours, limiting prolonged systemic exposure in healthy adults.

The rapid and predictable pharmacodynamic profile makes Cyclogyl suitable for same‑day diagnostic procedures, where precise assessment of refractive status is essential.

Conditions Treated with Cyclogyl

• Diagnostic Mydriasis for Refraction

  • Provides a stable, unaccommodated eye that allows accurate measurement of refractive error.
  • In Hong Kong, refractive errors affect an estimated 30 % of the adult population; cyclopentolate enables precise correction, reducing the burden of uncorrected vision.

• Cycloplegic Refraction in Pediatric Patients

  • Children often retain accommodation during standard refraction, leading to inaccurate readings. Cyclogyl temporarily halts accommodation, revealing the true refractive status.

• Pre‑operative Dilation for Intra‑ocular Surgery

  • Facilitates visualization of the anterior segment during cataract extraction, intra‑ocular lens placement, and laser procedures.

• Management of Anterior Uveitis‑Related Ciliary Spasm

  • By relaxing the ciliary muscle, Cyclogyl can reduce painful ciliary spasm associated with mild anterior uveitis, complementing anti‑inflammatory therapy.

These indications are aligned with the product labeling approved by the Hong Kong Department of Health and supported by peer‑reviewed ophthalmic literature.

Patient Groups Most Likely to Benefit

• Adults undergoing comprehensive eye examinations requiring accurate refractive measurements.
• Children (≥6 years) needing cycloplegic refraction to diagnose amblyopia or hyperopia.
• Patients scheduled for intra‑ocular lens implantation or laser refractive surgery, where pupil dilation improves surgical visualization.
• Individuals with mild anterior uveitis where ciliary spasm contributes to discomfort.

Contra‑indications: Patients with narrow‑angle glaucoma, known hypersensitivity to cyclopentolate or other anticholinergics, and infants younger than 6 months should avoid cyclopentolate due to the risk of severe systemic anticholinergic toxicity.

Risks, Side Effects, and Interactions

Common

• Transient blurred vision
• Photophobia due to sustained pupil dilation
• Stinging or burning sensation upon instillation
• Temporary increase in intra‑ocular pressure (observed in a minority of patients)

Rare

• Allergic contact dermatitis of the eyelid or conjunctiva
• Systemic anticholinergic effects such as dry mouth, tachycardia, or mild confusion (more likely in elderly patients or those with impaired hepatic metabolism)

Serious

• Acute angle‑closure glaucoma precipitated by mydriasis in predisposed individuals
• Severe systemic anticholinergic toxicity (e.g., delirium, hallucinations, urinary retention) especially after accidental overdose or in pediatric patients

Drug–Drug Interactions

• Pilocarpine or other miotic agents: Concurrent use may reduce the efficacy of Cyclogyl because miotics constrict the pupil, counteracting mydriasis.
• Systemic anticholinergics (e.g., atropine, scopolamine): Additive anticholinergic burden can increase the risk of systemic side effects.
• Topical beta‑blockers for glaucoma: May mask cycloplegic‑induced rise in intra‑ocular pressure, necessitating close monitoring.

Patients should disclose all ophthalmic and systemic medications to their healthcare provider before initiating Cyclogyl.

Practical Use: Dosing, Missed Dose, Overdose

• Standard Adult Dose: Instill 1 drop (approximately .05 mL) of Cyclogyl into the conjunctival sac of each eye. A second dose may be given after 5–10 minutes if a stronger cycloplegic effect is required.
• Pediatric Dosing: For children aged 6 years and older, a single .25% cyclopentolate drop is typically sufficient; higher concentrations (.5%) are reserved for cases where profound cycloplegia is needed.
• Missed Dose: Cyclogyl is generally used on an “as‑needed” basis for diagnostic procedures. If a scheduled dose is missed, the clinician may simply repeat the dose at the next appropriate appointment; no repeat dosing is required to maintain therapeutic effect.
• Overdose: In the event of accidental administration of multiple drops or ingestion, seek immediate medical attention or contact the Hong Kong Poison Centre (24‑hour hotline: 2824 2626). Monitor for signs of systemic anticholinergic toxicity, including rapid heart rate, flushing, agitation, or urinary retention.

Precautions

• Avoid contact with the cornea of the other eye, as systemic absorption can occur via the nasolacrimal duct.
• Do not combine with alcohol‑containing eye cosmetics, which may increase irritation.
• Patients with hepatic impairment should use the lowest effective dose and be monitored for prolonged systemic exposure.
