Orphenadrine citrate is a centrally acting skeletal muscle relaxant used to manage conditions involving involuntary muscle contraction.

- Muscle spasm: provides rapid relief of painful, involuntary muscle contractions. - Acute musculoskeletal pain: reduces associated pain and improves mobility. - Post‑operative muscle spasm: helps control spasm after surgical procedures. - Back strain: alleviates spasm and pain in lumbar muscles. - Neck strain: eases cervical muscle tension and discomfort.

Adverse reactions may occur with any dosage form of orphenadrine citrate.

Common Side Effects: - Drowsiness - Dry mouth - Blurred vision - Constipation - Dizziness - Nausea

Serious or Rare Side Effects: - Cardiac arrhythmia - Severe hypotension - Anaphylactic allergic reaction - Hepatotoxicity - Neuroleptic malignant‑like syndrome - Extrapyramidal symptoms

Use of orphenadrine citrate requires careful assessment and monitoring. - Assess renal and hepatic function: adjust use if impairment is present. - Monitor for anticholinergic effects: watch for confusion, urinary retention, or blurred vision. - Avoid in patients with narrow‑angle glaucoma: anticholinergic activity may worsen intra‑ocular pressure. - Use cautiously in the elderly: increased sensitivity to sedative and anticholinergic effects. - Avoid concurrent use with MAO inhibitors: risk of hypertensive crisis. - Store below 25°C: keep in the original pack, protect from moisture and light.

Orphenadrine citrate can interact with several drug classes, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid): - Monoamine oxidase inhibitors: risk of hypertensive crisis. - Tricyclic antidepressants: additive anticholinergic burden. - Central nervous system depressants: enhanced sedation and respiratory depression.

Moderate Interactions (Monitor Closely): - Antihistamines: increased anticholinergic side effects. - Beta‑blockers: possible additive cardiovascular effects.
