1. Name Of The Medicinal Product

Minims Tropicamide 0.5 %.

2. Qualitative And Quantitative Composition

Clear, colourless, sterile eye drops containing tropicamide Ph. Eur. 0.5 % w/v.

3. Pharmaceutical Form

Single-use, sterile eye drops.

4. Clinical Particulars

4.1 Therapeutic Indications

As a topical mydriatic and cycloplegic.

4.2 Posology And Method Of Administration

Adults (including the elderly):

1 drop followed by a second drop after an interval of 5 minutes. A further 1 drop may be instilled after 30 minutes, if required.

Children:

At the discretion of the physician.

4.3 Contraindications

Do not use in patients with a known hypersensitivity to tropicamide.

Tropicamide is contraindicated in narrow angle glaucoma and in eyes where the filtration angle is narrow, as an acute attack of angle closure glaucoma may be precipitated.

4.4 Special Warnings And Precautions For Use

Use with caution in an inflamed eye, as hyperaemia greatly increases the rate of systemic absorption through the conjunctiva.

Care should be exercised in small children.

Systemic absorption may be reduced by compressing the lacrimal sac at the medial canthus for a minute during and following the instillation of the drops. (This blocks the passage of drops via the naso-lacrimal duct to the wide absorptive area of the nasal and pharyngeal mucosa. It is especially advisable in children.)

None known.

5. Pharmacological Properties

5.1 Pharmacodynamic Properties

Tropicamide is a parasympatholytic agent, which acts by blocking the action of the parasympathetic nervous system. As acetylcholine is the neuro-humoral transmitter at the receptor site of the parasympathetic nervous system, tropicamide competes with acetylcholine for uptake at the receptor sites, thereby blocking its action. The results are mydriasis, due to unopposed action of the dilator pupillae, and cycloplegia.

5.2 Pharmacokinetic Properties

No data on the pharmacokinetics of topical tropicamide are available.

There are no preclinical data of relevance to the prescriber which are additional to that already included in other sections of the SPC.
