Leveraxo (Oxycodone Hydrochloride)

Oxycodone, an opioid analgesic, acts on the central nervous system to relieve pain.

• Moderate to severe acute pain: provides rapid and effective analgesia for short‑term use.
• Cancer‑related pain: helps control persistent pain associated with malignant disease.
• Post‑operative pain: reduces pain following surgical procedures to improve recovery.

• Oxycodone hydrochloride binds selectively to mu‑opioid receptors in the brain and spinal cord. Activation of these G‑protein coupled receptors inhibits the release of neurotransmitters involved in nociceptive transmission, decreasing neuronal excitability and altering pain perception. The result is increased pain threshold and reduced response to painful stimuli. These actions are dose‑dependent and contribute to the overall analgesic effect observed in patients.

Oxycodone may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects

• Nausea: feeling of sickness often accompanied by an urge to vomit.
• Constipation: reduced bowel movements leading to hard stools.
• Drowsiness: increased sleepiness or reduced alertness.
• Dry mouth: reduced salivation causing a parched feeling.

Serious or Rare Side Effects

• Respiratory depression: slowed or shallow breathing that can be life‑threatening.
• Severe hypotension: marked drop in blood pressure causing dizziness or fainting.
• Addiction or dependence: potential for misuse and physical reliance on the drug.

When prescribing oxycodone, clinicians should observe several safety considerations to minimize risk.

• Assess respiratory function: monitor for signs of depression, especially during initiation or dose escalation.
• Evaluate hepatic and renal function: adjust therapy if significant impairment is present.
• Avoid concomitant CNS depressants: concurrent use with benzodiazepines, alcohol, or other opioids increases sedation risk.
• Review patient history for substance abuse: identify risk of dependence or misuse before starting therapy.
• Pregnancy and lactation: use only if benefits outweigh potential risks to fetus or infant.
• Store at ambient temperature: keep in original packaging, protect from moisture and heat, and keep out of reach of children.

Oxycodone can interact with other medicines, altering its efficacy or safety profile.

Major Interactions (Avoid)

• Other opioids: additive respiratory depression and sedation.
• Benzodiazepines: heightened central nervous system depression.
• Alcohol: potentiates sedative effects and respiratory risk.

Moderate Interactions (Monitor Closely)

• CYP3A4 inhibitors (e.g., erythromycin, ketoconazole): increase oxycodone plasma concentrations.
• CYP3A4 inducers (e.g., rifampin, carbamazepine): reduce analgesic effect.
• Selective serotonin reuptake inhibitors (SSRIs): may increase risk of serotonin syndrome.
