OxyContin®LP 80 mg(Mundipharma)🇬🇧

Mechanism of Action

Oxycodone is a semi-synthetic opioid agonist that binds primarily to μ-opioid receptors in the central nervous system (CNS). By modulating pain signaling pathways at the spinal and supraspinal levels, it alters the perception and emotional response to pain, producing analgesia, sedation, and euphoria.

Indications (Therapeutic Use)

OxyContin® LP 80 mg is indicated for:

**The management of severe chronic pain requiring continuous, long-term opioid treatment when alternative treatment options are inadequate.

**Use in adults and adolescents aged 12 years and older.

Common Adverse Reactions:

**Constipation

Date of Initial Production

**Oxycodone, the active ingredient in OxyContin®, was first synthesized in Germany in 1916.

**OxyContin® (controlled-release formulation) was first introduced by Purdue Pharma in the United States in 1995, with global manufacturing licensed through affiliated Mundipharma companies.

Historical Background

  Oxycodone was originally synthesized as an attempt to create an opioid with the analgesic properties of morphine but fewer side effects. Over time, extended-release formulations such as OxyContin® were developed to reduce dosing frequency and maintain consistent blood levels in chronic pain patients.

  However, OxyContin® also became controversial due to its role in the opioid crisis, particularly in the United States, where its aggressive marketing and high abuse potential led to widespread misuse, addiction, and public health consequences.

Abuse and Misuse Potential

Oxycodone has high abuse potential. The prolonged-release tablet is designed to provide slow, controlled release over 12 hours. However, individuals seeking euphoria may crush, snort, or inject the tablets, bypassing the slow-release mechanism and increasing the risk of overdose and death.

OxyContin® has been reformulated in some regions with abuse-deterrent properties, but misuse remains a concern
