We propose that the transition temperature in the layered cuprates is affected by a peculiar interplay between doping and pair-breaking scattering. This scattering can lead to a depression of {ital T}{sub {ital c}} relative to its {open_quote}{open_quote}intrinsic{close_quote}{close_quote} value. Using this picture, one can explain the large value of {ital T}{sub {ital c}} in the three-layered cuprates relative to the two- and one-layer cuprates and also understand the large pressure effects observed. We predict that one can raise {ital T}{sub {ital c}} above the usual maximum value by applying pressure on underdoped TI-2201 samples and the maximum value of {ital T}{sub {ital c}} under pressure is evaluated. The temperature dependence of the pressure coefficient is also discussed. {copyright} {ital 1996 The American Physical Society.}
