Timolol

Ophthalmic timolol is a beta blocker used to reduce pressure inside the eye in glaucoma and ocular hypertension. The attached catalogue has one timolol-only bottle and two bottles that add another eye-pressure ingredient, creating a clear single and combination structure.

Cosopt

Open-angle Glaucoma, Ocular Hypertension

2% + 0.5%

Formulated to alleviate ocular fluid tension to support retinal safety and target fluid production.

From$32.33/ bottleView

Combigan

Open-angle Glaucoma, Ocular Hypertension

0.2% + 0.5%

Developed to mitigate elevated intraocular pressure to support visual field preservation and target fluid outflow.

From$34.17/ bottleView

Timoptic

Open-angle Glaucoma, Ocular Hypertension

0.50%

Formulated to target elevated intraocular pressure and to mitigate risk of vision impairment.

From$17.83/ bottleView

Key points

  • Ophthalmic timolol is a beta blocker.
  • It lowers pressure inside the eye.
  • Timoptic is the attached single-ingredient record.
  • Cosopt adds dorzolamide, while Combigan adds brimonidine.

Timoptic

Timoptic is catalogued as a 0.50% timolol bottle. Its attached topics are open-angle glaucoma and ocular hypertension within the eye care category.

The official Timoptic label identifies timolol maleate ophthalmic solution and expresses its strengths as 0.25% and 0.5% timolol equivalent. This source identity supports the brand and ingredient relationship while the attached catalogue retains its own stated value.

Cosopt and Combigan

Cosopt combines timolol with dorzolamide. Combigan combines timolol with brimonidine. Both are bottle records attached to the same two eye-pressure topics as Timoptic, but each has a second active ingredient.

Eye-applied timolol can still produce systemic beta-blocker effects. MedlinePlus and the official label include heart-rate and breathing precautions, making those effects important to the ingredient’s clinical identity.
