What is Phenylephrine 5% + Tropicamide 0.8% Eye Drops?
Itrop plus® are eyedrops used mainly for pupil dilation. The eyedrops solution contains two active components, phenylephrine 5% and tropicamide 0.8%. The two compounds act synergistically on the pupil’s muscles to increase the pupil diameter.
Eye dilation is an essential step in an ophthalmologic exam. As the pupil is a natural opening in the eyeball, Ophthalmologists and medical doctors use Eyedrops to dilate this hole and look into the inside of the eyeball.
Phenylephrine and tropicamide act on two different neurologic systems. They modulate the tone of the sympathetic and parasympathetic receptors to achieve maximum efficiency. The ideal eyedrops for the ophthalmological examination should have a set of properties:
- It should have a rapid onset of activity
- Achieves sufficient pupil enlargement
- Permits rapid recovery of normal eyesight
Itrop Plus® eyedrop has all of these properties due to its dual action on both systems controlling the pupils.

How do Itrops phenylephrine 5% and tropicamide 0.8% work?
The size of the pupils is under the control of the two sympathetic and parasympathetic systems. Ordinarily, the pupils dilate or constrict mainly to accommodate the amount of light entering the eyes. The change in pupils size is achieved by the constriction and dilation of the iris muscles.
When there is much light in the surroundings, the eyes react by narrowing the pupils. Consequently, only the precise amount of light reaches the visual receptors. When the surroundings are dark or poorly lighted, the pupils dilate, letting in as much light as possible to preserve the vision.
The sympathetic system responds to more than light intensity to cause mydriasis (pupil enlargement). It acts on the iris muscle to expand the pupil hole in emergencies. To provide maximum visual acuity, such as running from pressing danger.
Phenylephrine is a catecholamine, a molecule that intermediates sympathetic actions. Phenylephrine topical application on the eyes has the same effect as the sympathetic system. It results in mydriasis.
The parasympathetic system acts on the iris’s muscles to cause pupil constriction (miosis). It does so in reaction to excessive light or inflammation. Tropicamide is a compound that inhibits parasympathetic activity, allowing for unopposed pupils dilation.
Uses of Itrop Plus eye drops
Ophthalmologists and medical doctors use the combination of phenylephrine and tropicamide. Mydriasis allows a thorough exam of the interior eyeball structures. Direct visualization of the lens, vitreous fluid, and retina shows the structure in damage. Consequently, mydriasis is essential to make the diagnostics of eye conditions such as glaucoma and cataracts.
Additionally, mydriasis is an essential step for some ophthalmic surgical procedures. In cataracts surgery, the faulty lens is replaced with a synthetic implant. To gain access to the lens, the surgeons need a wide-open pupil.
Itrop Plus eye drops contain two compounds that efficiently cause mydriasis. An effect that is essential for both eye examination through an ophthalmoscope and surgical procedures. After the topical application of Itrop drops, the patient may experience side effects such as a stinging feeling in the eyes and temporary blurred vision.
