Cardiovascular Although Timolol maleate 10 mg tablets have no direct myocardial depressant activity, the continued depression of sympathetic drive through beta blockade may lead to cardiac failure in patients with latent cardiac insufficiency.
All patients should be observed for evidence of cardiac failure and, if it occurs, then treatment with beta blockers should be gradually withdrawn. If it is not possible to withdraw beta blocker treatment, then digitalisation and diuretic therapy should be considered.
g. coronary heart disease, Prinzmetal’s angina and cardiac failure) and hypotension, therapy with beta-blockers should be critically assessed and the 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.
Beta blockers should not be used in patients with untreated congestive heart failure. This condition should first be stabilised. In patients with ischaemic heart disease, treatment should not be discontinued suddenly. e. over 1-2 weeks.
If necessary, replacement therapy should be initiated at the same time, to prevent exacerbation of angina pectoris. Beta blockers may induce bradycardia. If the pulse rate decreases to less than 50-55 beats per minute at rest and the patient experiences symptoms related to the bradycardia, the dosage should be reduced.
In patients with peripheral circulatory disorders (Raynaud's disease or syndrome, intermittent claudication), beta blockers should be used with great caution as aggravation of these disorders may occur. Due to its negative effect on conduction time, beta-blockers should only be given with caution to patients with first degree heart block.
Respiratory disorders:
Respiratory reactions, including death due to bronchospasm in patients with asthma have been reported following administration of some beta-blockers. 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.
Hypersensitivity to timolol or to any of the excipients. Heart failure, unless adequately controlled, sinus bradycardia (<45 - 50 bpm) or heart block. Cardiogenic shock. History of bronchospasm and bronchial asthma. Chronic obstructive pulmonary disease.
Patients receiving monoamine oxidase inhibitors. Pregnancy. Sick sinus syndrome (including sino-atrial block), severe peripheral vascular disease or Raynaud's disease. Prinzmetal's angina. Untreated phaeochromocytoma. Metabolic acidosis.
Hypotension. Severe peripheral circulatory disturbances.

Metabolic/endocrine Timolol maleate 10 mg tablets should be administered with caution to patients with impaired renal function or impaired hepatic function. Patients with liver or kidney insufficiency may need a lower dosage. Timolol maleate 10 mg tablets may be used safely in diabetes.
It may, however, interfere with the cardiovascular and possibly the metabolic responses to hypoglycaemia and, therefore, should be used with caution in diabetic patients treated with insulin or oral hypoglycaemic agents as well as patients subject to spontaneous hypoglycaemia.
Beta-blockers could further increase the risk of severe hypoglycaemia when used concurrently with sulfonylureas. Diabetic patients should be advised to carefully monitor blood glucose levels. 5). Beta-blockers should be administered with caution in patients subject to spontaneous hypoglycaemia or to patients with labile diabetes, as beta blockers may mask the symptoms of thyrotoxicosis or hypoglycaemia.
Beta-blockers may also mask the signs of hyperthyroidism. Corneal diseases Beta-blockers may induce dryness of eyes. Patients with corneal diseases should be treated with caution. Other beta-blocking agents The known effects of systemic beta-blockade may be potentiated when timolol maleate is given to the patients already receiving a systemic betablocking agent.
The response of these patients should be closely observed. 5). Anaphylactic reactions While taking beta-blockers, patients with 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.
Beta blockers may increase sensitivity to allergens and the seriousness of anaphylactic reactions. g. of adrenaline. The anaesthesiologist should be informed when the patient is receiving timolol maleate. Other warnings Patients with a history of psoriasis should take beta blockers only after careful consideration.
There have been reports of skin rashes and/or dry eyes associated with the use of beta-adrenergic blocking drugs. The reported incidence is rare and in most cases the symptoms have cleared when treatment was withdrawn. Discontinuance of the drug should be considered if any such reaction is not otherwise explicable.
Cessation of therapy with the beta blocker should be gradual although withdrawal symptoms with timolol are infrequent. The following statement will appear on the label of this product: `Do not take this medicine if you have a history of wheezing or asthma'.
