It's important to understand that drugs are classified in two categories: therapeutic and pharmacologic. The therapeutic classification focuses more on the usefulness of the drug (ex: anticoagulants influence blood clotting) and the pharmacologic classification focuses more on the mechanism of action of the drug (ex: diuretics lower the plasma volume). I hope this helps and feel free to reach out if you need more information!
