Harrow announced the completion of the New Drug Application (NDA) transfer of moxifloxacin hydrochloride ophthalmic solution 0.5% (Vigamox), making the drug commercially available in the United States under the Harrow name. Vigamox is a fluoroquinolone antibiotic eye drop for the treatment of bacterial conjunctivitis caused by susceptible strains of organisms.1 Earlier this year, Harrow bought the US commercial rights to 5 branded ophthalmic products—Ilevro, Nevanac, Vigamox, Maxidex, and Triesence—making this NDA transfer completion the fourth FDA-approved product from the acquisition.2

“Having now completed the NDA transfer of Vigamox, we are excited to begin the implementation of the market access, marketing, inventory management, national sales detailing, and other brand‑leveraging strategies that we have developed during this transfer period,” said Mark L. Baum, Chief Executive Officer of Harrow.

“With an exceptional record of safety and efficacy, Vigamox is a well-known, reliable, and trusted product by US eye care professionals, many of whom regard Vigamox as the preferred broad-spectrum topical antibiotic to treat patients for bacterial conjunctivitis (sometimes referred to as 'pink eye') as well as many other common bacterial-based infections.”

Vigamox can now be ordered directly through Cardinal’s Cordlogistics, who partners with Harrow on product orders, including a wholesaler distribution system with McKesson and AmerisourceBergen.
