The three France internationals have all shaken off injuries and will be looked upon to provide a much-needed lift on Monday as Pardew's men seek to end a run of five straight defeats.
Leading scorer Remy and full-back Debuchy each featured as substitutes against Swansea City last weekend following respective calf and groin problems.
Ahead of the trip to Arsenal, Pardew said: "They will be up to speed and will be very important to this game."
Newcastle's boss will return to the touchline at the Emirates Stadium, having served a lengthy suspension for his altercation with Hull City's David Meyler last month.
"We need a result. Our recent run has not been good enough for our fans, me or my staff," Pardew added.
"The players are desperate to get a win. We need to show that we are a good team and that we're together.
"We need to put right the recent run with a committed performance."
Asked about the end of his suspension, Pardew said: "It'll be very pleasing to get back there (the touchline). I'll sit down a bit more but will still be at the side of the pitch."
