Lupin Pharmaceuticals Inc, the company's US subsidiary, launched its generic Gatifloxacin Ophthalmic Solution 0.5 percent in the US market, after having received the regulator's final approval earlier, Lupin said in a statement.

Gatifloxacin Ophthalmic Solution 0.5 percent, which is the generic equivalent of Zymaxid Ophthalmic Solution of Allergan, is indicated for the treatment of bacterial conjunctivitis.

"Zymaxid Ophthalmic Solution 0.5 percent had annual US sales of around $62.3 million, acording to IMS MAT data.

Lupin has been focusing on less competitive specialities spaces in the US market which includes segments like Oral Contraceptives, Ophthalmology and Dermatology.
