What is Iotim Eye Drops?
Iotim Eye Drops is manufactured by FDC and contains Timolol maleate 0.5% as a sterile ophthalmic solution. Timolol is a non-selective beta-blocker that blocks both beta-1 (cardiac) and beta-2 (bronchial) adrenergic receptors. It is one of the oldest and most studied IOP-lowering drugs.
How It Works
Timolol maleate blocks beta-adrenergic receptors on the ciliary epithelium, reducing the rate of aqueous humour secretion. This decreases the volume of fluid in the anterior chamber and lowers IOP by approximately 20–25%. Unlike prostaglandin analogs (which work on outflow), beta-blockers work on the production side of the equation — making them additive with prostaglandins and CAIs.

Local (eye): stinging on instillation, dry eye, blurred vision, conjunctival hyperaemia, corneal anaesthesia (rare).
Systemic (from absorption): bradycardia, hypotension, fatigue, depression, decreased exercise tolerance, decreased libido, bronchospasm in reactive-airway patients, masking of hypoglycaemia signs in diabetics.

Întrebări frecvente
How quickly does Iotim Eye Drops lower eye pressure?
IOP reduction begins within 30 minutes of the first dose and reaches near-maximum effect at 1–2 hours. Steady-state IOP is reached at 4 weeks.
Can I use Iotim Eye Drops with my heart medication?
Tell your prescriber if you take oral beta-blockers, calcium-channel blockers (diltiazem, verapamil), or digoxin. The combination can produce additive bradycardia and conduction blocks.
Is Iotim Eye Drops safe in asthma?
No — timolol is contraindicated in asthma, even when applied to the eye. Switch to betaxolol or a different drug class such as a prostaglandin analog or alpha-2 agonist.
What is the long-term tachyphylaxis effect?
Some patients show reduced response after weeks to months of continuous use (‘long-term drift’). If IOP drifts back up, your ophthalmologist may add a second agent rather than increase the dose.
Can I take Iotim Eye Drops if I'm a diabetic?
Yes, but with caution. Beta-blockers blunt the heart-rate response to hypoglycaemia, making low blood sugar harder to recognise. Sweating remains a reliable warning sign. Monitor blood glucose carefully when starting.
Why is once-daily not enough?
Most beta-blocker drops have an 8–12 hour duration of action, so twice-daily dosing maintains 24-hour IOP control. Some gel-forming preparations (timolol XE) extend duration and are dosed once daily.
What happens if I stop suddenly?
IOP returns to baseline within 1–2 weeks. There is no ophthalmic withdrawal syndrome. However, if you take oral beta-blockers as well, do not stop those abruptly without cardiology advice.
Can I wear contact lenses?
Remove lenses before instillation (preservative is benzalkonium chloride which can be absorbed by soft lenses) and wait 15 minutes before reinserting.
What is corneal anaesthesia?
Some beta-blockers cause mild reduction in corneal sensation. This is rare but can mask the discomfort of corneal abrasions or foreign bodies. Report any unusual eye pain promptly.
Can I use Iotim Eye Drops alongside oral medications for blood pressure?
Most combinations are safe but disclose all medications to your prescriber. ACE inhibitors, ARBs, and amlodipine are usually compatible. Avoid combining with oral beta-blockers without medical advice.
