Hydromorphinol

Hydromorphinol

Hydromorphinol is a semi-synthetic opioid analgesic derived from morphine. It is used in the management of moderate to severe pain. Hydromorphinol is known for its potent analgesic properties and is typically administered in a clinical setting.

Chemical Structure and Properties

Hydromorphinol is chemically similar to morphine, with the addition of a hydroxyl group at the 14-position and a hydrogenation of the 7,8-double bond. Its chemical formula is C17H21NO4, and it has a molecular weight of 303.35 g/mol.

Pharmacology

Hydromorphinol acts primarily on the mu-opioid receptors in the central nervous system, producing analgesia, sedation, and euphoria. It has a higher potency compared to morphine and a longer duration of action. The drug is metabolized in the liver and excreted primarily through the kidneys.

Medical Uses

Hydromorphinol is used for the relief of moderate to severe pain, particularly in patients who require continuous, long-term opioid treatment and for whom alternative treatment options are inadequate. It is often used in palliative care settings.

Side Effects

Common side effects of hydromorphinol include:

• Nausea
• Vomiting
• Constipation
• Drowsiness
• Dizziness

Serious side effects may include:

• Respiratory depression
• Hypotension
• Bradycardia
• Addiction and dependence

Regulation and Legal Status

Hydromorphinol is classified as a controlled substance in many countries due to its potential for abuse and addiction. It is typically available only by prescription and is subject to strict regulatory controls.

History

Hydromorphinol was first synthesized in the early 20th century as part of efforts to develop more effective pain management options. It has been used in various clinical settings since its introduction.
