This heightened calcium allows stronger contraction of the heart, while expending less energy. This causes sodium levels to build up inside the cells of the heart, which then causes calcium to increase inside the cell as well. In fact, in 2003 a nurse named Charles Cullen killed 40 of his patients with overdoses of digoxin and other heart medications.ĭigoxin works by inhibiting sodium, potassium, ATP channels in the heart. The use of digoxin changed how we treated cardiovascular disease for many years, but has since fallen out of favour due to some of its more dangerous side effects. It was used to treat a condition known as dropsy, which is an accumulation of fluid under the skin, often as a result of chronic heart failure. It was isolated from the foxglove plant (Digitalis lanata) in 1930, however, the first mention of foxglove derivatives for cardiac related conditions goes all the way back to 1785. Morphine, codeine, methadone, and Fentanyl are all used to provide varying potencies of pain management.ĭigoxin is a heart medication used for heart failure, and cardiac arrhythmias (such as atrial flutter, or atrial fibrillation). Heroin has since been banned in most countries due to high addiction rates and drug abuse, however, opiates in general are still widely used in modern medicine. It wasn’t until Felix Hoffmann (the creator of aspirin), re-synthesised it that it caught the attention of Bayer Pharmaceuticals, where it was commercialised as a pain management drug. In 1874, a chemist named C.R Alder Wright synthesised a similar compound called diamorphine, more commonly referred to as heroin.įor the first 23 years of this discovery, nothing was done. These alkaloids were discovered from the Opium poppy (Papaveraceae somniferum), starting with codeine and morphine. Most opiates are classified as benzylisoquinoline alkaloids which can be either naturally occurring, or synthetic. Opiates are a class of chemicals that target the opioid receptors in the human body that regulate pain and temperature control.
