- spasticity resulting from multiple sclerosis
- flexor spasms and concomitant pain, clonus and muscular rigidity
- skeletal muscle spasm resulting from rheumatic disorders

- cerebrovascular accidents or neoplastic or degenerative brain disease
Pharmacology
Baclofen inhibits both monosynaptic and polysynaptic reflexes at the spinal level by stimulating the GABA B receptors, 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-
- 10-20 mg (10-20 ml) for 12 month-2 years
- 20-30 mg (20-30 ml) for 2 years-6 years
- 30-60 mg (30-60 ml) for 6 years-10 years
Interaction
- Increased sedation may occur if Myorel 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 Myorel 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 Myorel and tricyclic antidepressants may potentiate the pharmacological effects of Myorel resulting in pronounced muscular hypotonia.
- In patients with Parkinsons disease receiving treatment with Myorel and levodopa and carbidopa, there have been several reports of mental confusion, hallucinations, headaches, nausea and agitation.
- The concurrent use of MAO inhibitors and Myorel 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 Myorel and magnesium sulphate or other neuromuscular blocking agents since a synergistic effect may theoretically occur.

Pregnancy & Lactation
Pregnancy category B3. Safe use of Baclofen during pregnancy has not been established. Baclofen crosses the placental barrier. Baclofen should only be administered to pregnant women when in the judgement of the physician concludes that the potential benefits outweigh the possible hazards. Baclofen is excreted in breast milk however evidence to date suggests that the quantities are so small that no undesirable effects on the infant would be expected.

- Patients with psychotic disorders, schizophrenia, depressive or manic disorders or confusional states should be treated cautiously and closely monitored as exacerbations of these disorders may occur.
- In patients with epilepsy and muscle spasticity, Myorel may be used under appropriate supervision and provided that adequate anticonvulsive therapy is continued.
- Myorel should be used with caution in patients with or with a history of peptic ulcers, cerebrovascular diseases, or hepatic, renal or respiratory failure.
- Careful monitoring of respiratory and cardiovascular function is essential especially in patients with cardiopulmonary disease and respiratory muscle weakness.
- During treatment with Myorel, neurogenic disturbances affecting emptying of the bladder may improve.
