  • Orphenadrine is used to treat muscle spasms/pain. It is usually used along with rest, physical therapy, and other treatment.
  • Aspirin is used to reduce fever and relieve mild to moderate pain from conditions such as muscle aches, toothaches, common cold, and headaches. It may also be used to reduce pain and swelling in conditions such as arthritis. Aspirin is known as a salicylate and a nonsteroidal anti-inflammatory drug (NSAID). It works by blocking a certain natural substance in your body to reduce pain and swelling. Consult your doctor before treating a child younger than 12 years. Your doctor may direct you to take a low dose of aspirin to prevent blood clots. This effect reduces the risk of stroke and heart attack. If you have recently had surgery on clogged arteries (such as bypass surgery, carotid endarterectomy, coronary stent), your doctor may direct you to use aspirin in low doses as a blood thinner to prevent blood clots.

Clinical Pharmacology

Orphenadrine citrate is a centrally acting (brain stem) compound which in animals selectively blocks facilitatory functions of the reticular formulation. Orphenadrine does not produce myoneural block, nor does it affect crossed extensor reflexes. Orphenadrine prevents nicotine-induced convulsions but not those produced by strychnine.Chronic administration of Orphenadrine Citrate, Aspirin, and Caffeine to dogs and rats has revealed no drug-related toxicity. No blood or urine changes were observed, nor were there any macroscopic or microscopic pathological changes detected. Extensive experience with combinations containing aspirin and caffeine has established them as safe agents. The addition of orphenadrine citrate does not alter the toxicity of aspirin and caffeine.The mode of therapeutic action of orphenadrine has not been clearly identified, but may be related to its analgesic properties. Orphenadrine citrate also possesses anticholinergic actions.

Indications And Usage

  • Norgesic Forte 50 mg/770mg/60 mg Tablets are indicated in:Symptomatic relief of mild to moderate pain of acute musculoskeletal disorders.The orphenadrine component is indicated as an adjunct to rest, physical therapy, and other measures for the relief of discomfort associated with acute painful musculoskeletal conditions.
  • The mode of action of orphenadrine has not been clearly identified, but may be related to its analgesic properties. Norgesic Forte Tablets do not directly relax tense skeletal muscles in man.


Because of the mild anti-cholinergic effect of orphenadrine, Norgesic Forte Tablets should not be used in patients with glaucoma, pyloric or duodenal obstruction, achalasia, prostatic hypertrophy, or obstructions at the bladder neck. Norgesic Forte Tablets are also contraindicated in patients with myasthenia gravis and in patients known to be sensitive to aspirin or caffeine.The drug is contraindicated in patients who have demonstrated a previous hypersensitivity to the drug.


Reye’s Syndrome may develop in individuals who have chicken pox, influenza, or flu symptoms. Some studies suggest possible association between the development of Reye’s Syndrome and the use of medicines containing salicylate or aspirin. Norgesic Forte Tablets 50mg/770mg/60mg contain aspirin and therefore are not recommended for use in patients with chicken pox, influenza, or flu symptoms.Norgesic Forte Tablets may impair the ability of the patient to engage in potentially hazardous activities such as operating machinery or driving a motor vehicle: ambulatory patients should therefore be cautioned accordingly.Aspirin should be used with extreme caution in the presence of peptic ulcers and coagulation abnormalities.

Usage In Pregnancy

Usage In Children

The safe and effective use of this drug in children has not been established. Usage of this drug in children under 12 years of age is not recommended.


Confusion, anxiety and tremors have been reported in a few patients receiving propoxyphene and orphenadrine concomitantly. As these symptoms may be simply due to an additive effect, reduction of dosage and/or discontinuation of one or both agents is recommended in such cases.Safety of continuous long term therapy with Norgesic Forte Tablets has not been established; therefore, if Norgesic Forte Tablets are prescribed for prolonged use, periodic monitoring of blood, urine and liver function values is recommended.

Adverse Reactions
