Oxycodone Actavis (Oxycodone Hydrochloride)

Oxycodone Actavis is an opioid analgesic that acts on the central nervous system to manage pain.

• Acute postoperative pain: Provides effective relief following surgical procedures.
• Cancer‑related pain: Helps control moderate to severe pain associated with malignancies.
• Chronic non‑cancer pain: Used when long‑term pain requires strong opioid therapy.

• Oxycodone binds to μ‑opioid receptors in the central nervous system, activating inhibitory G‑protein pathways that reduce neuronal excitability and diminish the perception of pain. This receptor activation also modulates neurotransmitter release, contributing to its analgesic effect.

Adverse reactions to oxycodone can vary from mild to severe and should be monitored during therapy.

Common Side Effects

• Nausea and vomiting: Frequent gastrointestinal upset.
• Constipation: Reduced bowel motility leading to hard stools.
• Drowsiness or sedation: Increased sleepiness or reduced alertness.
• Dizziness: Light‑headed sensations, especially when standing.
• Dry mouth: Reduced salivation causing oral discomfort.
• Sweating: Excessive perspiration without exertion.

Serious or Rare Side Effects

• Respiratory depression: Slowed or shallow breathing that can be life‑threatening.
• Severe hypotension: Marked drop in blood pressure.
• Seizures: Uncontrolled electrical activity in the brain.
• Allergic reactions: Rash, itching, swelling, or anaphylaxis.
• Dependence or addiction: Potential for misuse and physical dependence.
• Adrenal insufficiency: Rare hormonal imbalance affecting stress response.

When prescribing oxycodone, clinicians should consider several safety factors to minimize risk.

• Assess pain severity and prior opioid use: Determine if opioid therapy is appropriate.
• Evaluate respiratory function: Monitor for signs of respiratory depression, especially in opioid‑naïve patients.
• Review concomitant medications: Identify drugs that may increase sedation or respiratory risk.
• Monitor for signs of dependence: Watch for behavioral changes indicating misuse.
• Adjust dose in renal or hepatic impairment: Use lower doses and titrate cautiously.
• Store below 25°C: Keep in the original container, protect from moisture and direct sunlight.

Oxycodone may interact with a range of medicines, altering its effectiveness or safety profile.

Major Interactions (Avoid)

• CNS depressants (e.g., benzodiazepines, barbiturates): Heightened risk of respiratory depression and profound sedation.
• MAO inhibitors (e.g., phenelzine, selegiline): Can cause severe hypertension or serotonin syndrome.
• CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): Increase oxy‑hydroxy‑oxycodone plasma levels, raising overdose risk.

Moderate Interactions (Monitor Closely)

• CNS stimulants (e.g., cocaine, amphetamines): May counteract opioid sedation, leading to unpredictable effects.
• Antidepressants (e.g., SSRIs, SNRIs): Potential for serotonin syndrome when combined with other serotonergic agents.
• Diuretics: May enhance hypotensive effects, requiring blood pressure monitoring.
