Pharmacology
Baclofen inhibits monosynaptic and polysynaptic reflexes at the spinal level by stimulating GABA 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 given 4 times daily then raised according to requirement.
Interaction
- Increased sedation may occur if Myobac is taken with agents acting on the central nervous system, alcohol or synthetic opiates.
- Combined treatment with Myobac and antihypertensives is likely to increase the fall in blood pressure.
- The concomitant administration of Myobac and tricyclic antidepressants may potentiate the pharmacological effects of Myobac resulting in pronounced muscular hypotonia.
- In patients with Parkinsons disease receiving treatment with Myobac and levodopa and carbidopa, there have been several reports of mental confusion, hallucinations, headaches, nausea and agitation.
- The concurrent use of MAO inhibitors and Myobac may result in increased CNS depressant effects.
- Caution should be exercised when administering Myobac and magnesium sulphate or other neuromuscular blocking agents.

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.
Precautions & Warnings
- Lower doses should be used for patients with impaired renal function or those undergoing chronic hemodialysis.
- Patients suffering not only from spasticity but also from 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, Myobac may be used under appropriate supervision and provided that adequate anticonvulsive therapy is continued.
- Myobac 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 Myobac, neurogenic disturbances affecting emptying of the bladder may improve. However in patients with preexisting sphincter hypertonia, acute retention of urine may occur.
- Myobac has not significantly benefited patients with stroke. These patients have also shown poor tolerance to the medicine.
- Appropriate laboratory tests should be performed periodically in patients with hepatic diseases or diabetes mellitus to ensure that no medicine induced changes in these underlying diseases have occurred.
