History of Hydrocodone – Its origin, development, and evolution

The following is a brief introduction to the topic:

The powerful opioid drug hydrocodone has been used to treat pain and suppress coughs for many years. The history of hydrocodone reflects the development of medical science, and the struggle to balance the benefits and risks of pain relief and addiction. This article traces the history of the drug hydrocodone from its discovery until the present.

Hydrocodone: The Origins

Hydrocodone’s history begins with opium. Opium is a powerful natural pain reliever that comes from the opium poppies (Papaver somniferum). Opium’s analgesic, euphoric effects have been known for thousands of year. In the 19th century the active ingredients of opium (morphine, codeine) were studied and isolated, leading to various opioid medicines.

Opium and Morphine

Ancient civilizations such as Sumerians and Assyrians used opium for both medicinal and recreational purposes. The cultivation of opium poppy and its use spread throughout the world, including to Asia and the Mediterranean, and became an important part of traditional medicine.

Friedrich Serturner, a German Pharmacist, isolated the active alkaloid in opium and named it “morphine”, after Morpheus the Greek God of Dreams. This discovery was a major milestone in the history and treatment of pain, since morphine was widely used, especially during the American Civil War, as an effective analgesic.


In the same year, French chemists Francois Soubeiran and Pierre-Jean Robiquet isolated another opium-alkaloid. They named it “codeine” (after the Greek word “poppy-head”) after this discovery. Codeine was similar to morphine in its pain-relieving effects, but it was less potent and addictive. It was used to treat mild-to-moderate pain and coughs.

Hydrocodone Development

The history of hydrocodone can be traced to the mid-20th Century when pharmaceutical researchers were looking to develop a synthetic opioid that would have potent pain relieving properties, while also minimizing the side effects associated with opioids.

Early Synthesis

Carl Mannich, Helene Lowenheim and others first synthesized hydrocodone in Germany during the 1920s. The drug was developed initially as part of an experiment aimed at developing novel opioids. The semi-synthetic codeine derivative in hydrocodone was found to have a better side effect profile and be more effective for relieving pain than other opioids.

Introduction as a Medicine

In the United States, hydrocodone was first introduced in the 1940s with a product called “Vicodin.” Vicodin was a combination of hydrocodone and acetaminophen, also known as paracetamol. This combination provided effective pain relief and quickly became popular among healthcare professionals.

It was not accidental that acetaminophen had been added. It reduced the amount of hydrocodone required, which in turn decreased the risk of abuse and overdose.

The Evolution of Hydrocodone Usage

Over the decades, the use of hydrocodone and hydrocodone-containing products evolved significantly. It was prescribed for a variety of pain conditions including post-surgical, dental, and chronic pain. This widespread use wasn’t without challenges and controversy.

Changes in Regulation

Hydrocodone’s regulatory environment underwent changes in response to the increasing concern over misuse and addiction. The U.S. classified hydrocodone in 1971 as a Schedule II substance under the Controlled Substances Act. This was done to recognize its potential for abuse.

In 2014, U.S. Drug Enforcement Administration rescheduled combination hydrocodone products such as Vicodin from Schedule III into Schedule II. This further restricted its availability and required stricter controls. This change aimed to reduce the diversion and abuse of hydrocodone-containing medications.

Opioid Epidemic

The United States, despite these regulatory efforts, faced a major public health crisis of the 21st Century: the opioid epidemic. Like other opioids, hydrocodone was heavily involved in this crisis. Hydrocodone and other prescription opioids were widely abused, resulting in addiction, deaths from overdose, and severe social and economic consequences.

In order to combat this epidemic, several strategies have been implemented. These include prescription drug monitoring programs and increased education of healthcare professionals. Hydrocodone was re-evaluated in light of the opioid epidemic.

Reformulations of Combination Products

To address concerns about abuse and diversion, pharmaceutical companies began developing abuse-deterrent formulations of hydrocodone-containing products. These formulations were created to make it harder to crush, dissolve or otherwise tamper the medication to abuse.

In addition, there were new combinations of hydrocodone with non-opioid pain relievers such as nonsteroidal analgesics (NSAIDs) or other pain relievers. These combinations were designed to reduce the opioid exposure and provide pain relief, while also minimizing the risks of addiction.

Current Status and Future Directions

Hydrocodone is still a commonly prescribed pain medication, but it’s use has been subject to tight regulations and scrutiny as of my last update in January 2022. Hydrocodone prescription, dispensing, and monitoring have changed significantly since the opioid epidemic.

Opioid Prescription Guidelines

Healthcare providers in the United States are encouraged to use evidence-based guidelines for opioid prescribing when using hydrocodone or other opioids as pain relievers. These guidelines stress the importance of assessing a patient’s level of pain, evaluating non-opioid options, and using the lowest effective dosage for the shortest time possible.

Alternative Pain Management

Medical professionals continue to investigate alternative pain management approaches, such as physical therapy, non opioid medication, and interventional procedures. These methods are designed to reduce reliance on opioids such as hydrocodone, particularly for chronic conditions.

Research and Development

Ongoing research is being conducted to develop safer and more effective medications for pain. Scientists are exploring non-opioid therapy, new drug delivery systems and formulations that could offer better pain management with a reduced risk of side effects and addiction.

Opioid Education and Awareness

Education of the public and healthcare professionals on proper use, risks and possible consequences of opioid medication, including hydrocodone has become more important. In order to combat the opioid epidemic, it is important to raise awareness of the dangers associated with opioid misuse as well as the importance of responsible prescribing.

The conclusion of the article is:

The history of Hydrocodone is closely linked to the history of opioids and their changing role in healthcare. This journey, which began with the discovery of opium to the isolation of codeine and morphine, has seen significant advances.
