From the Guidelines
The recommended dose of baclofen for adults is 5 mg/kg once a day, with a usual dose of 300 mg, although doses of up to 450 mg are sometimes used, as stated in the British Thoracic Society guidelines 1. When considering the dosage of baclofen, it's essential to note that the guidelines provide specific recommendations for different age groups.
- For adults, the dose is 5 mg/kg once a day, with a typical dose of 300 mg, and a maximum of 450 mg in some cases.
- For children between 12 and 17 years, the dosage is also 5 mg/kg once a day.
- For younger children, between 1 month and 11 years, the dosage remains 5 mg/kg once a day, although the data supporting this is limited 1. It's crucial to follow these guidelines to ensure the safe and effective use of baclofen, considering its potential side effects and the importance of gradual tapering when discontinuing the medication. The medication's mechanism as a GABA-B receptor agonist is key to its therapeutic effects, and understanding its pharmacodynamics is vital for optimizing patient outcomes 1.

From the Research
Dose of Baclofen
- The dose of baclofen is not explicitly stated in the provided studies 3, 4, 5, 6, 7.
- However, the studies discuss the efficacy and safety of baclofen in treating spasticity in various conditions, including multiple sclerosis and non-progressive neurological disorders 4, 7.
- The studies also mention the use of baclofen in combination with other medications, such as nonsteroidal anti-inflammatory drugs, and its comparison with other antispasticity agents like tizanidine, diazepam, and dantrolene 4, 5, 7.
- It is essential to consult the prescribing information or a healthcare professional for the recommended dose of baclofen, as it may vary depending on the individual patient's needs and medical condition.
Administration and Efficacy
- Baclofen can be administered orally or intrathecally, with the latter being used for severe cases of spasticity 3, 6.
- The studies suggest that oral antispasticity drugs, including baclofen, are moderately effective in treating non-progressive neurological disorders 7.
- However, the efficacy of baclofen may vary depending on the individual patient's response and the specific condition being treated 4, 5.
Safety and Side Effects
- The studies mention that baclofen is generally well-tolerated, but it can cause side effects like sedation, muscle weakness, and global performance reduction 3, 4, 5.
- It is crucial to weigh the potential benefits and risks of baclofen treatment and monitor patients closely for any adverse effects 3, 6.
