Axant 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
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.
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)
The most common adverse reactions associated with Axant are transient drowsiness, daytime sedation, dizziness, weakness and fatigue. Central Nervous System : Headache (<10%), insomnia (<10%), and rarely, euphoria, excitement, depression, confusion, hallucinations, paraesthesia, nightmares, muscle pain, tinnitus, slurred speech, co-ordination disorder, tremor, rigidity, dystonia, ataxia, blurred vision, nystagmus, strabismus, miosis, mydriasis, diplopia, dysarthria, epileptic seizures, respiratory depression. Cardiovascular: Hypotension (<10%), rare instances of dyspnoea, palpitation, chest pain, syncope. Gastrointestinal : Nausea (approximately 10%), constipation (<10%) and rarely, dry mouth, anorexia, taste disorder, abdominal pain, vomiting, diarrhoea and positive test for occult blood in stool. Genitourinary : Urinary frequency (<10%) and rarely, enuresis, urinary retention, dysuria, impotence, inability to ejaculate, nocturia, haematuria. Other : Instances of rash, pruritus, ankle oedema, excessive perspiration, weight gain, nasal congestion, visual disturbances, hepatic function disorders and paradoxical increase in spasticity. Muscular hypotonia of a degree sufficient to make walking or movement difficult may occur but is usually relieved by readjusting the dosage. For this purpose, the daytime dosage may be reduced and the evening dosage increased.
Always consult a registered doctor before taking any medicine. This information is for general knowledge only.
Baclofen is contraindicated in patients with hypersensitivity to any component of this product.
Increased sedation may occur if Axant 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 Axant 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 Axant and tricyclic antidepressants may potentiate the pharmacological effects of Axant resulting in pronounced muscular hypotonia. In patients with Parkinsons disease receiving treatment with Axant and levodopa and carbidopa, there have been several reports of mental confusion, hallucinations, headaches, nausea and agitation. The concurrent use of MAO inhibitors and Axant 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 Axant and magnesium sulphate or other neuromuscular blocking agents since a synergistic effect may theoretically occur.
Lower doses (approximately 5 mg per day) should be used for patients with impaired renal function or those undergoing chronic haemodialysis. 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, Axant may be used under appropriate supervision and provided that adequate anticonvulsive therapy is continued. Lowering of the convulsion threshold may occur and seizures have been reported after the cessation of Axant therapy or with overdose. Axant 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 Axant, neurogenic disturbances affecting emptying of the bladder may improve. However in patients with preexisting sphincter hypertonia, acute retention of urine may occur. Axant should be used with caution in these circumstances. Axant 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.
