(Reuters) - Drugmaker Mylan N.V said it settled a patent litigation with Pfizer Inc related to the generic version of Viagra.

Mylan said the settlement would allow it to launch a generic version of the drug as early as December 2017, or sooner under certain conditions, subject to approval by U.S. health regulators.

Other terms of the settlement were not disclosed.
