The USMLE pharmacology tier list

For IMGs who keep restarting pharm: the order that makes it finite.

By Dr. Marish Asudani Β· Published

What is the best resource for USMLE pharmacology?

The High-Yield Pharmacology PDF and my Antimicrobials in 90 minutes video are S tier. Sketchy pharm, Osmosis, Mehlman pharm, Neil Randy pharm and the NBME Booster pharmacology deck are A. Dirty Medicine and Ninja Nerd pharm are B. Pixorize is D and Kaplan is F.

Read this firstI studied pharmacology from Sketchy, Osmosis, Kaplan and Dirty Medicine before I found the method that worked. Pharmacology isn't hard. Pharmacology is disorganised.

Every name below opens it. Here is how to read the tiers:

The syllabus

SThe High-Yield Pharmacology PDF

Why: every high-yield drug by system, and the 1 resource to learn each from. "This one document is what turns 3 weeks into 2 days." ▶Pharmacology in 48 hours, with the PDFHow to use it, page by page PDFThe High-Yield Pharmacology PDFFree. Also in the Vault University.
Per the map

ASketchy pharm

Why: the map names it for antiarrhythmics, digoxin, insulin and sulfonylureas, and the renal drugs.
Per the map

AOsmosis

Why: the map names it for neurology, anaesthesia, psychiatry, antihistamines, most antimicrobial groups, metformin and SGLT2 inhibitors.
Free playlist

AMehlman Β· Pharmacology

Why: short and dense, the way he does every system. His micro and pharm playlists are the ones I use for Step 3, with First Aid open. ▶Mehlman Β· PharmacologyPlaylist
Free playlist

ANeil Randy Β· Pharmacology

Why: the most slept-on channel on YouTube, and his pharmacology is no exception. Run it before an NBME. ▶Neil Randy Β· PharmacologyPlaylist
Final week

ANBME Booster pharmacology

Why: the final-week deck of every NBME pharm question.

BDirty Medicine Β· Pharmacology

Why: the map names it for the lipid-lowering drugs, plus 3 lipid metabolism videos watched first. ▶Dirty Medicine Β· PharmacologyPlaylist
Free playlist

BNinja Nerd Β· Pharmacology

Why: free, but long, and the map doesn't name it for any drug group. ▶Ninja Nerd Β· PharmacologyPlaylist

Pharm with the First Aid page openThe First Aid Guide teaches general pharmacology page by page, with MCQs under every page.

Mnemonics

DPixorize

Why: use "Sketchy plus Osmosis for pharmacology β€” but only where the map tells you to" instead.

Course

FKaplan

Why: I studied pharm from Kaplan before I built the method, and it isn't on the map for a single drug group. Same F as the Step 1 list.
