These impurities, including Dorzolamide Diastereomers, Dorzolamide Enantiomer, Dorzolamide intermediate Diastereomers, Dorzolamide Intermediate Enantiomer, Dorzolamide Maleic acid adduct, and Dorzolamide N-Desethyl N-Acetyl Analog, play a vital role in assessing the purity, reliability, and safety of Dorzolamide. Daicel Pharma also offers a customized synthesis of Dorzolamide impurities to cater to client requirements, with worldwide delivery options available.

Dorzolamide [CAS: 120279-96-1] is an antiglaucoma drug that acts as a carbonic anhydrase inhibitor. It lowers intraocular pressure in the treatment of open-angle glaucoma. Additionally, Dorzolamide serves as an antihypertensive agent.

Dorzolamide: Use and Commercial Availability  

Dorzolamide, available under Trusopt, is a second-generation inhibitor of carbonic anhydrase II that treats glaucoma. Dorzolamide lowers intraocular pressure by reducing the production of aqueous humor. It is formulated as a 2% eyedrop and effectively reduces intraocular pressure (IOP). Patients with open-angle glaucoma or ocular hypertension can benefit from Dorzolamide’s IOP-lowering effects.

Dorzolamide  Structure and Mechanism of Action Dorzolamide  Structure and Mechanism of Action

The chemical name of Dorzolamide is (4S,6S)-4-(Ethylamino)-5,6-dihydro-6-methyl-4H-thieno-[2,3-b]thiopyran-2-sulfonamide 7,7-dioxide. Its chemical formula is C10H16N2O4S3, and its molecular weight is approximately 324.4 g/mol.

Dorzolamide inhibits human carbonic anhydrase II in the ciliary processes of the eye and decreases aqueous humor secretion.

Dorzolamide Impurities and Synthesis

The formation of impurities in Dorzolamide can impact its quality, safety, and effectiveness. Impurities can arise during the synthetic process1 or storage of Dorzolamide and may include degradation products, residual solvents, or related substances. It is necessary to synthesize and characterize these impurities to understand their nature and potential impact. Analytical methods, such as chromatography and spectroscopy, help analyze and quantify impurities in Dorzolamide. Implementation of strict control measures helps establish acceptable limits for impurity levels, ensuring the quality and purity of Dorzolamide for safe and effective use in patients with glaucoma.

Daicel Pharma offers a comprehensive Certificate of Analysis (CoA) for Dorzolamide impurity standards, including Dorzolamide Diastereomers, Dorzolamide Enantiomer, Dorzolamide intermediate Diastereomers, Dorzolamide Intermediate Enantiomer, Dorzolamide Maleic acid adduct, and Dorzolamide N-Desethyl N-Acetyl Analog. They generate from an analytical facility that complies with cGMP standards. The CoA provides a detailed characterization report with data obtained through techniques such as 1H NMR, 13C NMR, IR, MASS, and HPLC purity analysis2. We give additional data like 13C-DEPT upon request. Daicel Pharma synthesizes unknown Dorzolamide impurities or degradation products. Every delivery has a complete characterization report.
