Before You Start

Use the sidebar on the left to jump to any module. Each module also has ← and → buttons at the bottom to step through in order.

Terms with a purple dotted underline are clickable — a definition card pops up in the corner of the screen.

Optional videos sit in collapsed boxes throughout the modules. Click to expand, or use the ↗ link to open on YouTube. The text covers everything on its own.

Modules 1–10 are the core content. Submodules (5a, 7a, 7b, etc.) go deeper on specific drugs — they're optional, skip them if you want.

This is an intro course — mechanisms are simplified on purpose. If something sparks your interest, the sources at the bottom of each module are a good place to go further.
