The player's counter-punching strategy and regular emotional displays on the playing surface had prompted observers to wonder if his capacity to perform at the elite level was finished.
However the 29-year-old has made changes in recent weeks, striving to advance forward and perform positively, reinforced by an better serving game.
The champion came back from a disadvantage in the opening set against the challenging Frenchman, winning 4 of the final five games to go ahead.
Both players exchanged break points in the second set before Moutet, attempting for his first tour victory, gained dominance to force a decider.
He saved four initial chances in a close third set before the Russian secured a break to that score to close out the victory.
Fittingly, Medvedev secured victory with a rally at the net, with the Frenchman unable to handle a shot after over two and a half hours.
