How we write, check and correct

Who writes PharmaWallah

PharmaWallah is built by a team of pharmacy students in Karachi for the Doctor of Pharmacy syllabus they are studying themselves. The team is listed on the About page. We are not a university, a regulator or a professional body, and nothing on the site is endorsed or accredited by one.

Pages are published under the byline “PharmaWallah team” unless a named person wrote them and agreed to be named. Some drafts are prepared with the help of AI writing tools; the checks below apply to every page however it was drafted.

How content is checked before it is published

• Formulas are compared with the source cited on the page. If we cannot find a reliable source for a formula, it is not published as fact.
• Worked examples and practice answers are recalculated independently — in code or by hand — and, on a calculator page, checked against what the calculator itself prints for the same inputs.
• Units are written out on every input, result and step, because most calculation errors in pharmacy are unit errors.
• Example values are illustrative. Where an example names a drug or a dose, it is there to practise the arithmetic, not as a recommendation.

How references are chosen

We cite standard pharmacy textbooks, pharmacopoeial chapters, international guidelines (such as ICH), and original papers for named equations. Every citation comes from one shared list in which the edition, year and publisher were checked against the publisher’s or issuing body’s own listing. We link only to the issuing body’s own site, and we do not quote page numbers we have not checked.

A reference supports the formula or principle on the page. It does not mean the author of that source has reviewed our page.

What the byline under a page means

• “Prepared by the PharmaWallah student team. Verify results with your textbook or instructor.” The team has carried out the checks above, and no named reviewer has signed the page off. This is the status of every page today.
• “Written by [name] · Reviewed by [name, qualification] on [date]”. Shown only when a real, named person wrote or reviewed that specific page and agreed to be named. No page carries a reviewer yet. We will not display a review without a real reviewer behind it.
• Draft. Work in progress. Drafts are not linked from the site or listed in our sitemap.

Reporting and correcting errors

If you find a mistake — a wrong formula, a unit error, a calculator result that disagrees with your working, or a broken page — please tell us through the contact form. Every calculator and guide has a “Report an error” link that fills in the page name for you.

We check each report against the cited source. If the page is wrong we correct it and change its “updated” date. Where a calculator has a known problem we have not yet fixed, we say so on the calculator page rather than leave it silent.

Educational use and clinical limits

PharmaWallah is for learning. Calculators and guides show how a calculation works; they are not a substitute for a validated laboratory method, an official monograph, a product’s approved labelling, or the judgement of a pharmacist or prescriber. Do not use a result from this site to decide a dose for a real patient.

Laboratory examples follow common Pharm-D practical methods. Where your institution’s method or specification differs, follow your institution.

How content is kept up to date

Each guide shows the date it was last substantively changed. We revisit a page when a cited guideline or pharmacopoeial chapter is revised, when an error is reported, and when we change the calculator it explains.
