Overview of Timolol Maleate as an API

Timolol maleate is a non-selective beta-adrenergic receptor blocker used in ophthalmology. Its potency, safety profile, and manufacturability make it a staple in glaucoma therapies. Pharmacologically, it reduces intraocular pressure by decreasing aqueous humor production.

The API's manufacturing demands rigorous controls, including:

• High chemical purity (>99%)
• Low residual solvents
• Consistent particle size distribution
• Compliance with pharmacopeial standards (USP, EP, JP)

In sourcing, compliance with Good Manufacturing Practice (GMP) and certification ensures API integrity and regulatory approval readiness.
