What is Timolol?
Timolol, the active ingredient in Oftan, is a beta blocker presented as an ophthalmic solution for ocular use. It treats open‑angle glaucoma and ocular hypertension by lowering intra‑ocular pressure.
GNH USA supplies Oftan as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.
What is Timolol used for?
Timolol is used in the management of ocular conditions that involve elevated intra‑ocular pressure.
Open‑angle glaucoma: reduces intra‑ocular pressure to slow disease progression. Ocular hypertension: lowers intra‑ocular pressure to prevent development of glaucoma. Secondary glaucoma: helps control pressure when other causes are present.
What are the side effects of Timolol?
Timolol may cause ocular and systemic adverse reactions.
Common Side Effects: - Burning or stinging sensation in the eye - Blurred vision - Dry eye or reduced tear production - Conjunctival hyperemia (redness) - Temporary visual disturbances - Mild headache
Serious or Rare Side Effects: - Bradycardia or heart block - Systemic hypotension - Bronchospasm or worsening asthma - Severe allergic reaction (angio‑edema, anaphylaxis) - Cardiac failure or worsening heart disease - Depression or mood changes
What precautions apply to Timolol?
Timolol requires careful assessment before and during therapy.
Assess cardiovascular status: check for bradycardia, heart block, or heart failure. Review respiratory history: avoid in patients with asthma or severe COPD. Monitor blood pressure: watch for systemic hypotension. Avoid concurrent non‑selective beta‑blockers: risk of additive cardiac effects. Store at room temperature: keep in original container, protect from light and moisture.
What does Timolol interact with?
Timolol can interact with other systemic and ocular agents.
Major Interactions (Avoid): - Systemic non‑selective beta‑blockers (e.g., propranolol): additive cardiac depression. - Calcium channel blockers (e.g., verapamil): increased risk of AV block. - Antiarrhythmic drugs (e.g., amiodarone): enhanced bradycardia.
Moderate Interactions (Monitor Closely): - Topical adrenergic agonists (e.g., epinephrine eye drops): reduced efficacy. - Other ocular hypotensives (e.g., prostaglandin analogs): additive pressure‑lowering effect. - Systemic antihypertensives: may potentiate hypotensive response.
