He then later determined that the drug was safe for humans and could provide pain relief.1 He tested out the dosage on himself and a few other subjects to determine that 15 mg was the dose with the most benefits (ie: euphoria) and least number of side effects (ie: fatigue, confusion, etc..).1

His new discovered medication had to be administered orally because the technology to take medications intravenously would not be around until 50 years later.1

Morphine was named after “Morpium” who was the Greek god of sleep and dreams.1

Opioids bind to receptors in the brain to block neurotransmission, causing inhibition, thus helping to reduce pain signals.1 There are 3 major receptors: mu, kappa, and delta.1 The Mu receptor is important because it causes a lot of the negative side effects of opioids including decreased respiration, the elimination of pain, and the feeling of euphoria throughout the entire body.1

The mu-receptors turn off GABAergic neurons to then flood the pleasure pathway with dopamine in the nucleus accumbens.1 Opioids cause increased tolerance which leads to withdrawal and dependence on the drug.1

This artifact is a video that describes the effects of various opioid derivatives. One part of the video that really stood out to me was when they said “the potency of opioids becomes diminished over time if you abuse them. Your pain becomes linked with the emotional and physical toil of opioid withdrawal”.1 This shows how truly addictive and dangerous opioids can be.

Merck & Company market morphine melinaseng https://padlet.com/melinaseng/ptsrca5d24uf1nqw/wish/2029963750 Friedrich Jacob Merck was the creator of the pharmaceutical company Merck & Co which began in Germany in 1668. It initially sold morphine, cocaine, and codeine as a pharmacy. Then in 1827, the company started as a manufacturer, manufacturing morphine. The company migrated to the United States in the late 19th century and opened up a manufacturing plant in New Jersey in 1902. Since then, Merck has had tremendous success, but also billions of dollars paid in lawsuits over its products.

This artifact is an image of one of the bottles of Merck & Co’s Morphine Sulphate which was sold in the 19th and 20the centuries for pain-relieving effects as well as cough and diarrhea.

This artifact provides information about the isolation of codeine by Pierre-Jean Robiquet as well as other notable achievements by him including asparagine, cantharidin, and caffeine.1

Pierre-Jean Robiquet’s experimenting on opium included evaporating opium to produce a syrup and then creating a white crystal solution that he called “narceine”.2 A series of evaporation, filtration, and recrystallization techniques allowed Robiquet to study the solubility and acidity of various opium alkaloids.2 He then was able to discover codeine from the residue left after evaporation which was insoluble in alkaline solutions but was different than morphine by the different colored reactions produced.2 Robiquet states that codeine was beneficial for the spinal cord, as it did not paralyze the back like morphine reportedly did.2

In addition to being prescribed when morphine and codeine was prescribed, heroin was also used to help patients overcome addiction from the prior opium alkaloids.1 As claimed by Congress at German Naturalists and Physicians in 1989, “heroin was ten times as effective as codeine in the treatment of respiratory disease, [however] he estimated that it had only one-tenth of the toxic effects”.1 This was a huge finding as there was a significant need for an effective and non-addictive treatment for a variety of diseases.1

Based on a review done in 1900, out of 341 respiratory cases, less than 8% of patients became addicted.1

It took almost 20 years after this point before physicians realized the negative effects of heroin, and the Public Health Service Hospitals in the US shut down dispensaries of heroin.1 In June 1924, congressional law prohibited manufacturing heroin.1

This artifact provides numerous different writings that were published and distributed about heroin in the late 19th century.1

Naloxone can be administered via the muscle (intramuscularly), through one's veins (intravenously), or in someone's nose (intranasally).1 By providing first responders with this medication, individuals who have overdosed have a stronger likelihood of surviving.1

This artifact is an image of how to properly administer naloxone via injection, which is only one of three routes of potential administration.2 By having people aware of this process and trained to use naloxone, we can significantly reduce the number of deaths via overdose of opioids.

Due to Robiquet’s extensive history, he would be the best person to fully explain this exhibit and the revolutionary ideas during the 19th century surrounding opioids.1
