Episode Asthma: Dreams of Anticholinergics Cover

Asthma: Dreams of Anticholinergics

Asthma treatment wasn’t always built around inhalers. It once came from poisonous plants, smoke, and a mysterious dream. In this episode, we explore the strange history of anticholinergics, tracing the path from Jimsonweed and belladonna to atropine, acetylcholine, and Otto Loewi’s discovery of “Vagusstoff.” We follow how Loewi’s frog-heart experiment helped prove that nerves communicate through chemical messengers, and how Henry Dale’s work connected those discoveries to the vagus nerve and airway constriction. We examine why early plant-based asthma remedies could open the airways while also causing dangerous side effects, and how that understanding eventually led to modern anticholinergic therapy. This episode reveals how a dream, a frog heart, and a toxic smoke helped shape the pharmacology of asthma.

Episode Breaking the RAAS Cycle: ACE Inhibition in Heart and Kidney Disease Cover

Breaking the RAAS Cycle: ACE Inhibition in Heart and Kidney Disease

From the discovery of a mysterious blood-pressure–lowering effect in the venom of a Brazilian pit viper to the development of the first ACE inhibitor, we trace how scientists transformed a deadly toxin into lifesaving medicine. We follow the work that identified bradykinin-potentiating peptides in snake venom and revealed that angiotensin-converting enzyme could be blocked—leading to the creation of captopril and later drugs such as enalapril and lisinopril. Along the way, landmark experiments and clinical trials showed that ACE inhibitors do far more than lower blood pressure, reshaping the treatment of heart failure and chronic kidney disease by targeting maladaptive activation of the renin–angiotensin–aldosterone system.
