Posology Recommended dosage in adults (including older people) The recommended dose is one drop of Bimatoprost/Timolol in the affected eye(s) once daily, administered either in the morning or in the evening. It should be administered at the same time each day.
Existing literature data for bimatoprost/timolol suggest that evening dosing may be more effective in IOP lowering than morning dosing. 1). If one dose is missed, treatment should continue with the next dose as planned. The dose should not exceed one drop in the affected eye(s) daily.
Renal and hepatic impairment Bimatoprost/Timolol has not been studied in patients with hepatic or renal impairment. Therefore caution should be used in treating such patients. Paediatric population The safety and efficacy of bimatoprost/timolol in children aged 0 to 18 years has not been established.
No data are available. Method of administration If more than one topical ophthalmic medicinal product is to be used, each one should be instilled at least 5 minutes apart. When using nasolacrimal occlusion or closing the eyelids for 2 minutes, the systemic absorption is reduced.
This may result in a decrease in systemic side effects and an increase in local activity.
Bimatoprost/Timolol Summary of the safety profile The adverse reactions reported in clinical studies using bimatoprost/timolol were limited to those earlier reported for either of the single active substances bimatoprost and timolol.
No new adverse reactions specific for bimatoprost/timolol have been observed in clinical studies. The majority of adverse reactions reported in clinical studies using bimatoprost/timolol were ocular, mild in severity and none were serious.
5% of patients. Tabulated list of adverse reactions Table 1 presents the adverse reactions that have been reported during clinical studies with all bimatoprost/timolol formulations (multi-dose and single-dose) (within each frequency grouping, adverse reactions are presented in order of decreasing seriousness) or in the post-marketing period.

Like other topically applied ophthalmic medicinal products, the active substances (timolol/ bimatoprost) in Bimatoprost/Timolol may be absorbed systemically. No enhancement of the systemic absorption of the individual active substances has been observed.
Due to the beta- adrenergic component, timolol, the same types of cardiovascular, pulmonary and other adverse reactions as seen with systemic beta-blockers may occur. Incidence of systemic ADRs after topical ophthalmic administration is lower than for systemic administration.
2. g. coronary heart disease, Prinzmetal's angina and cardiac failure) and hypotension therapy with beta-blockers should be critically assessed and therapy with other active substances should be considered. Patients with cardiovascular diseases should be watched for signs of deterioration of these diseases and of adverse reactions.
Due to its negative effect on conduction time, beta-blockers should only be given with caution to patients with first degree heart block. e. severe forms of Raynaud’s disease or Raynaud’s syndrome) should be treated with caution. Respiratory disorders Respiratory reactions, including death due to bronchospasm in patients with asthma have been reported following administration of some ophthalmic beta-blockers.
Bimatoprost/Timolol should be used with caution, in patients with mild/moderate chronic obstructive pulmonary disease (COPD) and only if the potential benefit outweighs the potential risk. Endocrine disorders Beta-adrenergic blocking medicinal products should be administered with caution in patients subject to spontaneous hypoglycemia or to patients with labile diabetes as beta-blockers may mask the signs and symptoms of acute hypoglycemia.
Beta-blockers may also mask the signs of hyperthyroidism. Corneal diseases Ophthalmic β-blockers may induce dryness of eyes. Patients with corneal diseases should be treated with caution Other beta-blocking agents The effect on intra-ocular pressure or the known effects of systemic beta-blockade may be potentiated when timolol is given to the patients already receiving a systemic beta-blocking agent.
1. Reactive airway disease including bronchial asthma or a history of bronchial asthma, severe chronic obstructive pulmonary disease. Sinus bradycardia, sick sinus syndrome, sino-atrial block, second or third degree atrioventricular block, not controlled with pace-maker.

The response of these patients should be closely observed. 5). Anaphylactic reactions While taking beta-blockers, patients with a history of atopy or a history of severe anaphylactic reaction to a variety of allergens may be more reactive to repeated challenge with such allergens and unresponsive to the usual dose of adrenaline used to treat anaphylactic reactions.
g. timolol, acetazolamide) after filtration procedures. g. of adrenaline. The anaesthesiologist should be informed when the patient is receiving timolol. Hepatic In patients with a history of mild liver disease or abnormal alanine aminotransferase (ALT), aspartate aminotransferase (AST) and/or bilirubin at baseline, bimatoprost had no adverse reactions on liver function over 24 months.
There are no known adverse reactions of ocular timolol on liver function. Ocular Before treatment is initiated, patients should be informed of the possibility of eyelash growth, darkening of the eyelid or periocular skin and increased brown iris pigmentation since these have been observed during treatment with bimatoprost and bimatoprost/timolol.
Increased iris pigmentation is likely to be permanent, and may lead to differences in appearance between the eyes if only one eye is treated. After discontinuation of bimatoprost/timolol, pigmentation of iris may be permanent. 2%. 5% and did not increase following 3 years treatment.
The pigmentation change is due to increased melanin content in the melanocytes rather than to an increase in the number of melanocytes. The long term effects of increased iridial pigmentation are not known. Iris colour changes seen with ophthalmic administration of bimatoprost may not be noticeable for several months to years.
Neither nevi nor freckles of the iris appear to be affected by treatment. Periorbital tissue pigmentation has been reported to be reversible in some patients. Macular oedema, including cystoid macular oedema, has been reported with bimatoprost/timolol.
g. intraocular surgery, retinal vein occlusions, ocular inflammatory disease and diabetic retinopathy). g. uveitis) because the inflammation may be exacerbated. Skin There is a potential for hair growth to occur in areas where bimatoprost/timolol solution comes repeatedly in contact with the skin surface.
Thus, it is important to apply Bimatoprost/Timolol as instructed and avoid it running onto the cheek or other skin areas. Excipients The preservative in Bimatoprost/Timolol, benzalkonium chloride, may cause eye irritation. Contact lenses must be removed prior to application, with at least a 15-minute wait before reinsertion.
Benzalkonium chloride is known to discolour soft contact lenses. Contact with soft contact lenses must be avoided. Benzalkonium chloride has been reported to cause punctate keratopathy and/or toxic ulcerative keratopathy. Therefore monitoring is required with frequent or prolonged use of […]
