Dihydrocodeine
Dihydrocodeine
Dihydrocodeine (/daɪˌhaɪdroʊkoʊˈdiːn/) is a semi-synthetic opioid analgesic prescribed for pain or severe dyspnea, or as an antitussive, either alone or compounded with paracetamol (as in co-dydramol) or aspirin. It was developed in Germany in 1908 and first marketed in 1911.
Etymology
The term "Dihydrocodeine" is derived from the Greek words "di" meaning "two", "hydro" meaning "water", and "codeine", a type of alkaloid found in opium. The "dihydro" prefix indicates that two hydrogen atoms have been added to the codeine molecule.
Pharmacology
Dihydrocodeine is twice as strong as codeine and has a slightly longer half-life. Like all opioids, dihydrocodeine works by binding to specific receptors in the brain and spinal cord, blocking the transmission of pain signals.
Side Effects
Common side effects of dihydrocodeine include dizziness, nausea, and constipation. More serious side effects may include respiratory depression and addiction.
