MediMorph performs dose conversions to make calculating equivalent doses between narcotics easy. Performing dose conversions by hand can be inaccurate and tedious, so MediMorph aims to provide a simple fix to this issue by allowing you to perform dose conversions between common narcotics with a few easy taps. Conversions are based on the gold standard resource for opiate dosing "Demystifying Opioid Conversion Calculations: A Guide for Effective Dosing" by Mary Lynn McPherson. Features: - Dose conversions between common narcotics - Conversions for both PO (oral) and IV/SQ (intravenous/subcutaneous) administration (for applicable narcotics) - Reduced dose calculation (medical literature recommends initial dose reduction of 25-50% when switching between opiates) - Display of conversion steps used to perform calculation - Local history of calculations performed - Notes, references, and disclaimer Feel free to reach out if you have any questions or feedback, and thanks for taking a look!
