A medical syringe assembly includes a first opening and a second opening at opposite ends of a tubular barrel having an inner wall. The inner wall includes an inner surface. A stopper having an engagement surface is slidably received in the tubular barrel and includes a portion for engaging the surface of the inner wall of said tubular barrel. A lubricant is disposed over a limited area of at least one member of the inner wall of the tubular barrel and the engagement surface of said stopper, whereby a sufficient amount of the lubricant is available to provide adequate reduction of friction between the surface of the inner wall of the tubular barrel and the engagement surface of the stopper.
