|Description||Dorzolamide (MK-507, L-671152) HCl is a water-soluble, potent inhibitor of human carbonic anhydrase II and IV with Ki of 1.9 nM and 31 nM, respectively, used as anti-glaucoma agent.|
Dorzolamide is a powerful inhibitor of carbonic anhydrase (CA) II that penetrates the sclera and cornea to reach the ciliary process and lowers formation of HCO3 and aqueous humor.  Dorzolamide causes a vasodilatation of retinal arteries, pre-contracted by three different mechanisms by direct action and presumably independent of changes in extracellular pH. 
|In vivo||Dorzolamide, administered twice and three times daily, significantly decreases intraocular pressure (IOP) in glaucomatous dogs on the first day (twice daily 7.6 mmHg, and three times daily 16.4 mmHg) that is even greater by day 5 (twice daily 10.4 mmHg, and three times daily 13.9 mmHg). Dorzolamide (instilled in the drug eye for day 1 through to day 5) combined with oral methazolamide (administered from day 3 through to day 5) significantly lowers IOP in the eye on day 1, for day 3 and for all of day 5 for both eyes. Dorzolamide (2%) instilled three times daily produces similar IOP declines compared to the combination of oral methazolamide and 2% dorzolamide administered twice daily.  Dorzolamide hydrochloride induces a very large IOP reduction and is found to be also well effective at night in rabbit.  Dorzolamide maximally lowers the intraocular pressure (IOP) of glaucomatous monkeys by 22%, 30% and 37%, respectively. |

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
