What is Timolol 0.25% Teika?
Timolol 0.25% Teika is used alone or together with other medicines (such as hydrochlorothiazide) to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled.
Timolol 0.25% Teika is also used after an acute heart attack to decrease its severity and prevent another heart attack. It may also be used to help prevent migraine headaches.
Timolol 0.25% Teika is a beta-blocker. It works by affecting the response to nerve impulses in certain parts of the body, like the heart. As a result, the heart beats slower and decreases the blood pressure. When the blood pressure is lowered, the amount of blood and oxygen is increased to the heart.
Timolol 0.25% Teika is available only with your doctor's prescription.

Myocardial infarction (secondary prevention): To reduce mortality following MI
Off Label Uses
Atrial fibrillation (rate-control)
Data from a randomized, placebo-controlled trial in patients with atrial fibrillation (AF) associated with a rapid ventricular response while receiving digoxin supports the use of oral Timolol 0.25% Teika in patients with chronic AF.

Timolol 0.25% Teika description
Each mL of Timolol 0.25% Teika 0.5% contains 5 mg of Timolol 0.25% Teika (6.8 mg of Timolol 0.25% Teika maleate). It also contains the following inactive ingredients: Gellan gum, tromethamine, mannitol and water for injection. Benzododecinium bromide 0.012% is added as preservative.
Preservative-free Timolol 0.25% Teika contains the previously mentioned active and inactive ingredients except for the preservative benzododecinium bromide.
Timolol 0.25% Teika maleate is a β-adrenergic receptor blocking agent. It is (S)-1-[(1,1-dimethylethyl)amino]-3-[[4-(4-morpholinyl)-1,2,5-thiadiazol-3-yl]oxy]-2-propanol (Z)-2-butenedioate (1:1) (salt). Timolol 0.25% Teika maleate possesses an asymmetric carbon atom and is provided as the levo isomer. The empirical formula is C13H24N403S·C4H404.
Timolol 0.25% Teika maleate has a molecular weight of 432.50. It is a white, odourless, crystalline powder which is soluble in water, methanol and alcohol.
Gellan solution contains a highly purified anionic heteropolysaccharide derived from gellan gum. Aqueous solutions of gellan gum form a clear transparent gel in the presence of cations. The concentration of sodium cations in tears is ideally suited to cause gelation of the material when topically instilled in the conjunctival sac.

What other drugs will affect Timolol 0.25% Teika?
Timolol 0.25% Teika should be used cautiously in patients with hyperthyroidism, hypertension and cardiac arrhythmias. All vasopressors should be used cautiously in patients taking monoamine oxidase (MAO) inhibitors.
Timolol 0.25% Teika should not be administered concomitantly with other sympathomimetic drugs (such as isoproterenol) because of possible additive effects and increased toxicity.
Combined effects may induce serious cardiac arrhythmias. They may be administered alternately when the preceding effect of other such drug has subsided.
Administration of epinephrine to patients receiving cyclopropane or halogenated hydrocarbon general anesthetics such as halothane which sensitize the myocardium, may induce cardiac arrhythmia.. When encountered, such arrhythmias may respond to administration of a beta-adrenergic blocking drug. Timolol 0.25% Teika also should be used cautiously with other drugs (e.g., digitalis, glycosides) that sensitize the myocardium to the actions of sympathomimetic drugs.
Diuretic agents may decrease vascular response to pressor drugs such as epinephrine.
Timolol 0.25% Teika may antagonize the neuron blockade produced by guanethidine resulting in decreased antihypertensive effect and requiring increased dosage of the latter.
