: The process begins by identifying biological pathways or molecules (like proteins) associated with a disease. Pharmacologists use this to establish a hypothesis for how a drug might alleviate symptoms or cure the condition. Quantitative Reasoning
Using panels of 50+ receptors and ion channels (e.g., the CEREP panel), pharmacologists screen promising compounds for unwanted interactions. The most infamous example: terfenadine (Seldane), an antihistamine that blocked hERG potassium channels in the heart, causing fatal arrhythmias. Today, hERG screening is mandatory early in discovery. pharmacology in drug discovery and development
Before you can design a key, you need to understand the lock. In pharmacological terms, the "lock" is the biological target—usually a receptor, enzyme, ion channel, or nucleic acid—responsible for a disease process. : The process begins by identifying biological pathways
