Fenobac Tablet 10 mg


  • 8.00Tk.



This product has a minimum quantity of 10

Indications

Baclofen is indicated in-
  • spasticity resulting from multiple sclerosis
  • flexor spasms and concomitant pain, clonus and muscular rigidity
  • skeletal muscle spasm resulting from rheumatic disorders
  • spinal cord injuries and other spinal cord diseases
  • cerebrovascular accidents or neoplastic or degenerative brain disease

Pharmacology

Baclofen inhibits both monosynaptic and polysynaptic reflexes at the spinal level by stimulating the GABAreceptors, which inhibits the release of glutamate and aspartate. It may also act at intraspinal sites producing CNS depression. Baclofen also exerts an antinociceptive effect.

Dosage & Administration

Adult & children over 10 years: 5 mg 3 times daily, preferably with or after food, gradually increased; max. 100 mg daily.

Children <10 years
: Treatment is usually started with 2.5 mg (2.5 ml) given 4 times daily then raised according to requirement. Daily maintenance dose-
  • 12 month-2 years: 10-20 mg (10-20 ml)
  • 2 years-6 years: 20-30 mg (20-30 ml)
  • 6 years-10 years: 30-60 mg (30-60 ml)

Interaction

  • Increased sedation may occur if Baclofen is taken with agents acting on the central nervous system, alcohol or synthetic opiates. The risk of respiratory depression is also increased.
  • Combined treatment with Baclofen and antihypertensives is likely to increase the fall in blood pressure; therefore the dosage of antihypertensive medication should be adjusted accordingly.
  • The concomitant administration of Baclofen and tricyclic antidepressants may potentiate the pharmacological effects of Baclofen resulting in pronounced muscular hypotonia.
  • In patients with Parkinsons disease receiving treatment with Baclofen and levodopa and carbidopa, there have been several reports of mental confusion, hallucinations, headaches, nausea and agitation.
  • The concurrent use of MAO inhibitors and Baclofen may result in increased CNS depressant effects. Caution is advised and the dosage of one or both agents should be adjusted accordingly.
  • Caution should be exercised when administering Baclofen and magnesium sulphate or other neuromuscular blocking agents since a synergistic effect may theoretically occur.

Contraindications

Baclofen is contraindicated in patients with hypersensitivity to any component of this product.
