Pharmacy maths, Solved.
106 pharmacy calculators that show their formula and working, for Doctor of Pharmacy students in Pakistan — plus 22 course lessons, spotting slides, 8 wet-lab simulations and a clinical reference desk.
What PharmaWallah is
PharmaWallah is a free study site for Doctor of Pharmacy students in Pakistan, built by pharmacy students. It is for the calculations, notes and lab practice that come up in a Pharm-D course: preparing a dilution for a practical, working out a dose in a pharmaceutics exam, or reading a stability or pharmacokinetics data sheet.
The largest part is the 106 calculators, each showing its formula and the working behind the answer, so you can check your own method rather than copy a number. Alongside them are 5 calculation guides with worked examples and practice questions, 22 units of course notes in 4 first-semester subjects with practice MCQs, slide-spotting lessons, and lab simulations. The calculators also work offline in the Android app.
The team checks every formula against the textbook or guideline cited on the page and recalculates each worked example independently. Pages are prepared by the student team; where a named person has reviewed a page, the page says so. If you find a mistake, every page has a link to report it, and the editorial policy explains how we correct it.
Still being built: notes for more subjects and more calculation guides. Everything here is for learning — verify results with your textbook or instructor, and never use them to dose a real patient.
