20sec search on google. No. When the manga ended, Ranma never got rid of the curse, and there's no info on what happened to anyone after it ended.

The series ended with a possibility in the future to remove the curse but after Ranma and Akana finally confessed to each other Ranma seems to doesn't care much about the curse anymore but again the final was an open final and kinda feels like if the series didn't have a proper conclusion with a lot of vague questions at the end.
