A picture of the sides and slide mechanism would help for an accurate answer. My drawers are simple. Extend the drawer all the way, then lift and tilt the handle end while continuing to pull out. that action moves the drawer past its stop in the track and allows it to be lifted out.
Other slide types may have a release button on each track, just behind the face of the drawer which needs to be depressed while pulling past its stop. Pic would help.
