Matrifen

Fentanyl, the active ingredient in Matrifen, is an opioid analgesic presented as a transdermal patch for transdermal use. It provides continuous pain relief for patients with chronic severe pain or cancer‑related pain who require round‑the‑clock opioid therapy.

The company adheres to European Union quality standards and provides reliable logistics for global distribution. Our network ensures timely delivery and regulatory support for each market.

Matrifen (fentanyl) is used in the management of pain conditions that require continuous opioid therapy. - Chronic severe pain: provides sustained analgesia for patients with persistent, high‑intensity pain unresponsive to non‑opioid treatments. - Cancer pain: controls moderate to severe pain associated with malignant disease, improving quality of life. - Chronic non‑cancer pain: offers continuous relief for severe musculoskeletal or neuropathic pain when other therapies have failed.

Matrifen may cause a range of adverse reactions, which are categorized by frequency.

Common Side Effects: - Nausea - Constipation - Dizziness - Somnolence - Dry mouth - Application site erythema or itching

Serious or Rare Side Effects: - Respiratory depression - Severe hypotension - Opioid dependence or withdrawal syndrome - Skin necrosis at the patch site - Anaphylactic reaction

When prescribing Matrifen, clinicians should consider several safety measures. - Respiratory assessment: evaluate baseline respiratory function before initiating therapy. - Addiction monitoring: watch for signs of opioid dependence or misuse. - Dose adjustment: modify dose in patients with renal or hepatic impairment. - Concomitant CNS depressants: avoid or use with caution when combined with benzodiazepines or alcohol. - Elderly patients: start at the lowest effective dose and monitor closely. - Store at room temperature: keep in the original pouch, protect from light and moisture.

Matrifen can interact with other medicines, affecting its safety or efficacy.

Major Interactions (Avoid): - Other opioids: additive respiratory depression risk. - MAO inhibitors: may cause severe hypotension or serotonin syndrome. - CNS depressants (e.g., benzodiazepines): increase sedation and respiratory depression. - Strong CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): raise fentanyl plasma levels. - Respiratory depressants used in anesthesia: potentiate respiratory suppression.

Moderate Interactions (Monitor Closely): - CYP3A4 inducers (e.g., rifampin): may reduce analgesic effect. - Alcohol: can enhance sedation and respiratory depression. - Antihistamines: may increase sedation. - Diuretics: may affect fluid balance and blood pressure. - Certain antidepressants (e.g., SSRIs): monitor for enhanced CNS effects.
