Summary of Product Characteristics Updated 14-Jun-2017 | Bausch & Lomb U.K Limited
Minims Prednisolone Sodium Phosphate
Clear, colourless, sterile eye drops containing Prednisolone Sodium Phosphate Ph. Eur. 0.5% w/v.
For the full list of excipients, see section 6.1.
Sterile single-use eye drop.
Non-infected inflammatory conditions of the eye.
Adults and the elderly
One or two drops applied topically to the eye as required.
At the discretion of the physician.
Use is contraindicated in viral, fungal, tuberculous and other bacterial infections.
Prolonged application to the eye of preparations containing corticosteroids has caused increased intraocular pressure and therefore the drops should not be used in patients with glaucoma.
In children, long-term, continuous topical corticosteroid therapy should be avoided due to possible adrenal suppression.
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.
Care should be taken to ensure that the eye is not infected before Minims Prednisolone is used.
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.).
Visual disturbance may be reported with systemic and topical corticosteroid use. If a patient presents with symptoms such as blurred vision or other visual disturbances, the patient should be considered for referral to an ophthalmologist for evaluation of possible causes which may include cataract, glaucoma or rare diseases such as central serous chorioretinopathy (CSCR) which have been reported after use of systemic and topical corticosteroids.
Corticosteroids are known to increase the effects of barbiturates, sedative hypnotics and tricyclic antidepressants.
They will, however, decrease the effects of anticholinesterases, antiviral eye preparations and salicylates.
Co-treatment with CYP3A inhibitors, including cobicistat-containing products, is expected to increase the risk of systemic side-effects. The combination should be avoided unless the benefit outweighs the increased risk of systemic corticosteroid side-effects, in which case patients should be monitored for systemic corticosteroid side-effects.
Topical administration of corticosteroids to pregnant animals can cause abnormalities of foetal development and although the relevance of this finding to human beings has not been established, the use of Minims Prednisolone during pregnancy should be avoided.
Not known: vision, blurred (see also section 4.4)
Prolonged treatment with corticosteroids in high dosage is occasionally associated with cataract.
The systemic effects of steroids are possible following the use of Minims Prednisolone, but are, however, unlikely due to the reduced absorption of topical eye drops.
Cases of corneal calcification have been reported very rarely in association with the use of phosphate containing eye drops in some patients with significantly damaged corneas.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via:
Yellow Card Scheme
As Minims are single dose units, overdose is unlikely to occur.
Pharmacotherapeutic group: Corticosteroids, plain, ATC code: S01BA04
Mechanism of action
The actions of corticosteroids are mediated by the binding of the corticosteroid molecules to receptor molecules located within sensitive cells. Corticosteroid receptors are present in human trabecular meshwork cells and in rabbit iris ciliary body tissue.
Prednisolone, in common with other corticosteroids, will inhibit phospholipase A2 and thus decrease prostaglandin formation.
The activation and migration of leucocytes will be affected by prednisolone. A 1% solution of prednisolone has been demonstrated to cause a 5.1% reduction in polymorphonuclear leucocyte mobilisation to an inflamed cornea. Corticosteroids will also lyse and destroy lymphocytes. These actions of prednisolone all contribute to its anti-inflammatory effect.
The oral availability, distribution and excretion of prednisolone is well documented. A figure of 82 ± 13% has been quoted as the oral availability and 1.4 ± 0.3ml/min/kg as the clearance rate. A half life of 2.1 - 4.0 hours has been calculated.
With regard to ocular pharmacokinetics, prednisolone sodium phosphate is a highly water soluble compound and is almost lipid insoluble. Therefore, theoretically it should not penetrate the intact corneal epithelium. Nevertheless, 30 minutes after instillation of a drop of 1% drug, corneal concentrations of 10µg/g and aqueous levels of 0.5µg/g have been attained. When a 0.5% solution was instilled in rabbit eyes every 15 minutes for an hour, an aqueous concentration of 2.5µg/ml was measured. Considerable variance exists in the intraocular penetration of prednisolone depending on whether the cornea is normal or abraded.
It can be seen that only low levels of prednisolone will be absorbed systemically, particularly where the cornea is intact.
Any prednisolone which is absorbed will be highly protein-bound in common with other corticosteroids.
The use of prednisolone in ophthalmology is well-established. Little specific toxicology work has been reported, however, the breadth of clinical experience confirms its suitability as a topical ophthalmic agent.
