| Drug Name: | TIMOPTIC |
| Manufacturer: | Merck & Co., Inc. |
| Other Info: | Beta-adrenergic blocking agents may mask certain clinical signs (e.g., tachycardia) of hyperthyroidism. Patients suspected of developing thyrotoxicosis should be managed carefully to avoid abrupt withdrawal of beta-adrenergic blocking agents that might precipitate a thyroid storm. |
| Clinical Trials: | |
As with many topically applied ophthalmic drugs, this drug is absorbed systemically.The same adverse reactions found with systemic administration of beta-adrenergic blocking agents may occur with topical administration.
For example, severe respiratory reactions and cardiac reactions, including death due to bronchospasm in patients with asthma, and rarely death in association with cardiac failure, have been reported following systemic or ophthalmic administration of timolol maleate (see CONTRAINDICATIONS).
