If you've taken Step 1 recently, the pharmacological knowledge will help tremendously. If not, I think it's still too much for Step 2 CK to dive into a pharmacology book. Your CK review books will have associated drugs and treatment methods (in addition to relevant common SEs and CIs) along with each topic. At least Kaplan lecture notes have it this way. And with Qbanks, you will further solidify your knowledge.
