Minims Tropicamide 0.5 %.
Clear, colourless, sterile eye drops containing tropicamide Ph. Eur. 0.5 % w/v.
Single-use, sterile eye drops.
As a topical mydriatic and cycloplegic.
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.
At the discretion of the physician.
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.
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.)
Tropicamide may cause increased intraocular pressure. The possibility of undiagnosed glaucoma should be considered in some patients, such as elderly patients. Determine the intraocular pressure and an estimation of the depth of the angle of the anterior chamber prior to initiation of therapy.
There is no evidence as to the drug's safety in human pregnancy, nor is there evidence from animal work that it is free from hazard. This product should only be used in pregnancy if considered essential by the physician.
Patient warning: Patients who receive a mydriatic may suffer from photophobia and this may impair their ability to drive under certain circumstances.
Transient stinging, dry mouth and blurred vision may occur following the use of this product.
Systemic effects from Minims Tropicamide are not expected. Should an overdose occur causing local effects, e.g. sustained mydriasis, pilocarpine or 0.25% w/v physostigmine should be applied.
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.
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.
Store below 25°C. Do not freeze. Protect from light.
