Overview
Cyclopentolate (HCl) is antimuscarinic agent and used to dilate the pupil in ophthalmology with more rapid onset and shorter duration.
Indications
Cyclopentolate (HCl) is primarily indicated in conditions like Diagnostic aid for mydriasis and cycloplegia.
Contraindications
Cyclopentolate (HCl) is contraindicated in conditions like Narrow-angle glaucoma.
Side Effects
Ocular The following ocular adverse experiences have been associated with the use of CYCLOMYDRIL ® (cyclopentolate hydrochloride and phenylephrine hydrochloride ophthalmic solution): increased intraocular pressure, burning/irritation upon instillation, photophobia, blurred vision and superficial punctate keratitis. Nonocular Use of cyclopentolate hydrochloride has been associated with psychotic reactions and behavioral disturbances in children. These disturbances include ataxia, incoherent speech, restlessness, hallucinations, hyperactivity, seizures, disorientation as to time and place. This drug produces reactions similar to those of other adrenergic and anticholinergic drugs; however, the central nervous system manifestations as noted above are most common. Other manifestations of adrenergic and anticholinergic topical ophthalmic drugs include tachycardia, hyperpyrexia, hypertension, vasodilation, urinary retention, diminished gastrointestinal motility, convulsion, bradycardia, apnea, necrotizing colitis and abdominal distention (in newborns and especially premature infants), skin rash, drowsiness, and decreased secretion in salivary and sweat glands, pharynx, bronchi and nasal passages. Severe manifestations of toxicity include coma, medullary paralysis and death. Systemic toxicity can result from topical application of sympathomimetic drugs: headache, blood pressure elevation, extrasystoles, tachycardia, syncope and cerebrovascular accidents have been reported.
Warnings
FOR TOPICAL OPHTHALMIC USE ONLY. NOT FOR INJECTION. There have been reports of serious cardiovascular reactions, including ventricular arrhythmias and myocardial infarctions, in patients using higher concentrations of phenylephrine. These episodes, some fatal, have usually occurred in patients with pre-existing cardiovascular diseases. This preparation may cause central nervous system (CNS) disturbances. This is especially true in younger age groups, but may occur at any age, especially with the stronger solutions. Infants are especially prone to CNS and cardiopulmonary side effects from cyclopentolate.

Adult Dosage
0.5 mg (0.5 (0.5)) As recommended. Ophthalmic — Repeated after 5 min 1 % (1 (1)) As recommended. Ophthalmic — Repeated after 5 minutes. Scraped Dose — Excessive dosage may produce behavioral disturbances, tachycardia, hyperpyrexia, hypertension, elevated intraocular pressure, vasodilation, urinary retention, diminished gastrointestinal motility and decreased secretion in salivary and sweat glands, pharynx, bronchi and nasal passages. Pulmonary oedema or cardiac arrest may occur due to phenylephrine toxicity. Severe intoxication is characterized by central nervous system depression, coma, circulatory and respiratory failure, and death. Patients exhibiting signs of overdosage should receive supportive care and monitoring.
Child Dosage
0.5 mg (0.5 (0.5)) As recommended. Opthalmic — Once or repeated in 5min as required
Neonatal Dosage
0.5 mg (0.5 (0.5)) As recommended. Opthalmic — Once or repeated in 5min as required
