RxFlip is the ultimate flashcard and quiz-based learning tool for healthcare students and professionals looking to master the most commonly prescribed outpatient medications. Using adaptive learning best practices, RxFlip delivers concise, high-yield information to strengthen your core drug knowledge—without the clutter of bloated drug references. Unlike other drug study apps, RxFlip focuses on clear, practical knowledge to help you confidently learn the most important facts of the top 250 medications (also known as the Top 200 or Top 300 Drugs). This is a learning tool, not a drug reference, so it is designed to streamline your studying, improve retention, and build a rock-solid foundational understanding of these medications. == Designed For Healthcare Students and Providers == RxFlip is perfect for healthcare students and providers, including pharmacists, technicians, nurses, physician assistants, and physicians. It is also an excellent resource to prepare for the drug therapy aspects of standardized exams, including NAPLEX, BCPS, PTCB, PANCE/PANRE, NCLEX, and more. === Key Features of RxFlip === • Engaging flashcard and quiz modes - reinforce learning through interactive study sessions • Fully customize your studying - select what drug classes you want to study, and what facts you want to review (brand name, generic name, drug class, indications, adverse effects, and typical dosing) • Smart quizzing algorithms - quiz mode includes a selection algorithm to randomly identify plausible distractor answers to keep you challenged and engaged • Adaptive learning mode - spend more time on the drugs you struggle with, not the ones you already know. • Drug pronunciation - listen to audio of how a drug's brand or generic name is pronounced as you study == A High-Yield, Comprehensive Drug Database == • The drug database comes pre-built with key facts of the top 250 drugs based on prescription utilization data in the US. Key facts are curated by a board-certified pharmacist and professor to ensure only the most important details are included for studying. • Customize the drug database by adding or removing drugs, modifying drug entries, and even record your own pronunciations • Group drugs into therapeutic categories or classes to create your own custom drug list for studying • Save, export, and import customized drug database files between devices or users == Track Your Progress with Adaptive Learning == • Monitor your progress after each flashcard or quiz session • An adaptive learning and spaced repetition algorithm ensures you spend more time on drug facts you haven't mastered yet while still revisiting areas that you previously mastered == Expertly Designed for Maximum Learning == RxFlip is designed by a board-certified pharmacist, pharmacy educator, and professor of pharmacy practice ensuring accurate, high-yield, and relevant drug information. The drug list is generated from the ClinCalc.com DrugStats Database project and many drug facts mirror those from the ClinCalc Top 250 Drugs Online Course (https://top250drugs.com). == Looking for FlashRX? == FlashRX, released in 2011, was the predecessor to RxFlip, and has now been phased out of development. RxFlip has a modern, sleek interface, new functionality, and a completely revamped drug database. RxFlip is backwards compatible and able to import most legacy FlashRX databases.
