The QPR loanee is tied for fifth in the Premier League in goals, and the Newcastle boss says it will be a challenge to compete a deal.
The QPR loanee's late strike secured a 1-0 win over Aston Villa on Sunday as the Magpies scored a league goal at St. James' Park for the first time this year.
It was Remy's 12th goal of the season and Pardew acknowledges that if the France international continues to find the net this season, it could prove difficult to bring him back to the club on a permanent basis.
"He is going to be hot property and will get a lot of headlines," said Pardew. "His goals could make it harder to buy him. Perhaps I will leave him out of the next 11 games.
"The quality players can slow the game down — he can do that. His all-around game was terrific — the game seemed a little bit slower when he was on the ball, not as frantic. Remy was the one player to have that composure to score that goal. He was the best player on the pitch."
Remy's loan deal will see him return to Loftus Road at the end of the season, with parent club QPR currently in the running for promotion to the Premier League.
