Book excerpt: This is the Pocket Pharmacopoeia for the power user! The expanded version of the classic Tarascon Pocket Pharmacopoeia continues the high-quality tradition of a convenient and organized pocket manual detailing typical drug dosing (both FDA approved and off-label uses), available trade and generic formulations, metabolism, Canadian trade names, relative pricing information, and safety in pregnancy and lactation. The Deluxe takes it all a step further by including additional drugs and dosing indications, black-box warnings, notes regarding adverse effects and drug interactions, and a table of cytochrome P450 isozymes. Packed with this expanded information and more tables than the Classic, the Deluxe is still small enough to comfortably fit in your lab coat pocket. As with the Classic, all entries are meticulously peer-reviewed by drug information experts and clinicians of multiple specialties.
