Optimide
Optimide Uses, Dosage, Side Effects, Mechanism of Action, How Long Does it Take to Work? Optimide is a brand name. Its generic name is Tropicamide.
Optimide
Optimide is a topical antimuscarinic medication that is used to reduce the particle size of the pupil of the eye to inhibit visual accommodation for diagnostic and therapeutic procedures. It has a marked effect on pupillary size and a marked effect on visual accommodation for a short duration of time.
Uses for
Optimide is used to reduce pupil size for diagnostic procedures like ophthalmoscopy, endothelial specular microscopy, fundus photography, and tonography. Its use also includes therapeutic management of acute angle-closure glaucoma and sympathetic ophthalmia.
Mechanism of Action
Optimide binds to muscarinic acetylcholine receptors on the iris sphincter muscle resulting in a decrease in the muscle's contractility. This results in mydriasis (dilation) and cycloplegia (paralysis of accommodation). Optimide is also believed to decrease intraocular pressure.
How Long Does It Take to Work?
Optimide begins to take effect within 30 minutes and can last for up to 8 hours.
Absorption
Optimide is rapidly absorbed through the corneal and conjunctival epithelium. It is also absorbed through the ciliary body and iris.
Route of Elimination
Optimide is metabolized in the liver and excreted through the kidneys.
Dosage
The recommended dose of tropicamide is one drop of a 0.5% or 1% solution into the conjunctival sac of the affected eye. The strength and amount of medicinal product must be specified when prescribing and/or dispensing tropicamide.
Administration
Optimide is administered via topical ophthalmic route. It should not come into contact with the eye lids and conjunctivae.
Side Effects
The most common reported side effects from tropicamide use are burning, stinging, discomfort or a feeling of foreign body sensation in the eyes, blurred vision, myopia, conjunctival hyperemia, decrease in intraocular pressure, transient ischemic optic neuropathy, ciliary block glaucoma, circumpapillary telengiectasia, purulent conjunctivitis, cystoid macular edema, and keratitis. It can also cause systemic effects on the cardiovascular system, such as tachycardia and hypertension.
Toxicity
Optimide is not known to be toxic at therapeutic doses. In case of accidental ingestion, the effects may include blurred vision, drowsiness, insomnia, loss of appetite, nausea, vomiting and increased salivation and bronchial secretions.
Precaution
Patients should be monitored for signs and symptoms of systemic side effects such as hypertension and tachycardia, especially in those with a history of cardiovascular disease. Long-term use of tropicamide may increase the risk of cataracts so patients should be monitored for any changes in vision. It should not be used in patients with known hypersensitivity to anticholinergics.
Interaction
Optimide may interact with other medications, including anticonvulsants, antidepressants, antiarrhythmics, digitalis glycosides, narcotics, orphenadrine, quinidine, and sedatives. It may also interact with antihistamines, antimuscarinics, and para-aminobenzoic acid.
Disease Interactions
Optimide should be used with caution in patients with angle-closure glaucoma, congestive heart failure, urinary retention, arrhythmias, and bronchial asthma. It may exacerbate narrow angle glaucoma in some patients.
Drug Interactions
Optimide may interact with other ophthalmic products such as mydriatics, miotics, adrenergics, anti-inflammatory agents, and antiglaucoma agents. It may also interact with medications used to treat neurological disorders, cardiovascular disorders, and gastrointestinal disorders.
Food Interactions
Optimide should not be taken with food, as it can impair absorption.
Pregnancy Use
Optimide should be used during pregnancy only if clearly needed. The safety and efficacy of the drug in pregnant women has not been established.
Lactation Use
Optimide is excreted in the breast milk, and should not be used during lactation.
Acute Overdose
Acute overdose of tropicamide may cause tachycardia, hypertension, and CNS disturbances, although the effects are usually mild. Treatment is symptomatic and supportive.
Contraindication
Optimide is contraindicated in patients with narrow angle glaucoma, hypersensitivity to anticholinergics, and in patients with a history of peptic ulcer disease, bladder neck obstruction, or hiatal hernia.
Use Direction
Optimide should be administered as one drop of the appropriate concentration into the conjunctival sac of the affected eye three to four times daily. It should not be used for more than 2 weeks without consulting a physician.
Storage Condition
Optimide should be stored at room temperature between 15° C and 30° C. Protect from light and moisture and keep away from children.
Volume of Distribution
The volume of distribution for tropicamide is approximately 10-15L/kg.
Half Life
The elimination half-life of tropicamide is approximately 1.6 hours.
Clearance
The clearance of tropicamide is approximately 35-60 mL/min/kg.

How does Optimide work?
Optimide works by temporarily paralyzing the ciliary muscle of the eye, which is responsible for pupil constriction. By paralyzing this muscle, the pupil remains dilated for a period of time.
What are the uses of Optimide?
Optimide is used to temporarily expand the pupil or to enhance visualization of the anterior segment of the eye. It may be used during ophthalmic procedures such as retinal examination, gonioscopy, or the placement of iris lenses, and for diagnosis of conditions including glaucoma and cataracts.
What is the dosage of Optimide?
The recommended dose of Optimide is 0.5–1% solution, usually applied as single drops into conjunctival sacs. Children may require lower dosages.
