Norflex (Orphenadrine Citrate)

Orphenadrine citrate, the active ingredient in Norflex, is a centrally acting muscle relaxant presented as a tablet for oral use. It is used to relieve muscle spasm and associated pain in adult patients with acute musculoskeletal conditions.

GNH USA supplies Norflex as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Orphenadrine citrate is a centrally acting muscle relaxant indicated for conditions involving skeletal muscle spasm.

- Muscle spasm: reduces involuntary muscle contraction and associated discomfort. - Acute musculoskeletal pain: alleviates pain from strains, sprains or minor injuries. - Post‑operative musculoskeletal discomfort: helps control pain and spasm after surgical procedures.

Adverse reactions may occur with any centrally acting muscle relaxant.

Common Side Effects: - Dry mouth: reduced salivary secretion causing a feeling of thirst. - Drowsiness: mild to moderate sedation, especially after initial doses. - Dizziness: sensation of light‑headedness or imbalance. - Blurred vision: temporary visual disturbances. - Constipation: slowed gastrointestinal motility. - Nausea: mild stomach upset.

Serious or Rare Side Effects: - Tachycardia: rapid heart rate requiring medical evaluation. - Urinary retention: difficulty emptying the bladder. - Severe allergic reaction: rash, swelling, or breathing difficulty. - Hepatotoxicity: signs of liver injury such as jaundice. - Psychotic symptoms: hallucinations or confusion in susceptible individuals. - Cardiac arrhythmias: irregular heart rhythms observed in rare cases.

Before prescribing Norflex, clinicians should consider patient‑specific factors and safety measures. - Pregnancy: use only if the potential benefit justifies the potential risk to the fetus. - Breastfeeding: caution advised as the drug may be excreted in milk. - Elderly patients: start with lower doses and monitor for increased sedation. - Hepatic impairment: dose adjustment may be required due to reduced metabolism. - Concomitant CNS depressants: avoid additive sedation or respiratory depression. - Store at ambient temperature: keep below 25 °C, retain in original packaging, protect from moisture and direct sunlight.

Orphenadrine citrate can interact with several medication classes, influencing efficacy or safety.

Major Interactions (Avoid): - Monoamine oxidase inhibitors (MAOIs): risk of hypertensive crisis. - Anticholinergic drugs: additive anticholinergic burden leading to severe dry mouth, constipation, or urinary retention. - CNS depressants (e.g., benzodiazepines, opioids): heightened sedation and respiratory depression.

Moderate Interactions (Monitor Closely):\n- Antihistamines: increased drowsiness. - Beta‑blockers: may mask tachycardia. - Alcohol: potentiates central nervous system effects. - Antihypertensive agents: possible additive blood pressure lowering.
