indications for Timolol Maleate Ophthalmic Solution

Timolol Maleate is the most commonly prescribed medication for veterinary use in the treatment of glaucoma in animals. The medication is a beta-blocker that effectively reduces the pressure mounting inside dogs’ eyeballs. This medication is used in conjunction with other drugs in the management of intraocular pressure in animals. Timolol is a beta-blocker, which is taken in by the anterior segment of the eye. This lowers the formation of aqueous humor, thus reducing the pressure. Moreover, the medication helps to ease down the heart functions as well as the blood pressure. The medication is used in treating glaucoma in both dogs and cats. Timolol Maleate is a topical drug that can be obtained by prescription and is available as suspension eye drops.


Do not use the medication in animals with known hypersensitivity to the drug or any other beta-blockers. Take extra care or if possible avoid using the medicine in animals with congestive heart diseases or respiratory complications. It is best to exclude cats with asthma or any other respiratory diseases from treating with the medication. Timolol Maleate has a tendency to interact when in certain combinations. In addition, ensure that the dropper tip is not exposed to any surface. Medication overdose can cause a drop down in the heart rate and bronchospasm.


Prior consultation with the veterinarian is necessary before administering the medication in the animal. The usual suggested dosage is one drop, twice a day; however, in severe cases, the dosage can be increased to three times daily.
