Lioresal, also known as Baclofen, is a medication used to treat muscle spasms. The active ingredient in Lioresal is Baclofen, which helps relax muscles. It’s also sometimes called by its generic name, Baclofen. Doctors prescribe it for conditions like multiple sclerosis and spinal cord injuries.
Expect to pay anywhere from £0.57 to £2.07 for a pills of Lioresal. The disparity in cost arises from packaging volume and the grade of active ingredients (30 or 360 mg).
Lioresal is the brand name for Baclofen. Baclofen is a muscle relaxant and antispastic agent primarily used to alleviate muscle spasticity. The chemical name for Baclofen is beta-(aminomethyl)-p-chlorohydrocinnamic acid.
Lioresal is indicated for the treatment of spasticity resulting from multiple sclerosis, especially for the relief of flexor spasms and concomitant pain, clonus, and muscular rigidity. It can also be used for patients suffering from spinal cord diseases.
Lioresal is available in tablet form and as an intrathecal solution. The tablets are typically 10 mg and 20 mg. The intrathecal solution is administered via a pump directly into the spinal fluid.
Baclofen exerts its effects by mimicking the action of the neurotransmitter gamma-aminobutyric acid (GABA) on the GABAB receptors, resulting in inhibitory nerve transmission in the central nervous system. This action helps reduce muscle spasticity.
After oral administration, Baclofen is rapidly absorbed from the gastrointestinal tract. It has a bioavailability of approximately 70-80%. Peak plasma concentrations are reached within 2 hours. Baclofen is primarily excreted unchanged by the kidneys.
Dose adjustments may be necessary for patients with renal impairment since Baclofen is excreted primarily by the kidneys. Elderly patients may require starting with a lower dose. Close monitoring is recommended to avoid potential overdosage.
Common side effects of Lioresal include drowsiness, dizziness, weakness, and fatigue. Some patients may experience gastrointestinal disturbances such as nausea and constipation, as well as hypotension.
Baclofen can interact with other central nervous system depressants, such as alcohol, antihistamines, and opioids, increasing the risk of sedation. Concomitant use with tricyclic antidepressants and antihypertensive medications may potentiate hypotensive effects.
Lioresal is contraindicated in patients with hypersensitivity to Baclofen or any of the components in the formulation. It should not be abruptly discontinued to prevent withdrawal symptoms such as seizures or hallucinations.
Special caution should be taken when prescribing Baclofen to pregnant or breastfeeding women, as well as children. The safety and efficacy in these populations have not been fully established.
Regular monitoring of renal function and liver enzymes is recommended during long-term treatment with Baclofen. Patients on intrathecal Baclofen should have pump function and catheter patency routinely monitored.
Oral Baclofen should be titrated gradually to minimize side effects. The initial dose typically starts at 5 mg three times daily, increasing by increments of 5 mg every three days, based on patient response and tolerability, up to a maximum dose of 80 mg/day.
Baclofen tablets should be taken with meals to reduce gastrointestinal discomfort. For intrathecal administration, the pump should be filled by healthcare professionals trained in the procedure to ensure accurate dosing.
Lioresal tablets should be stored at room temperature, away from moisture and direct sunlight. The intrathecal solution should be stored according to specific recommendations to maintain its stability and sterility.
Patients should be informed about the potential for drowsiness and advised not to operate heavy machinery or drive until they know how Baclofen affects them. They should be instructed to avoid alcohol and other CNS depressants during treatment.
In cases of suspected overdose, patients may present with symptoms of severe gastrointestinal disturbances, hypotonia, or respiratory depression. Immediate medical attention is essential, and supportive measures such as maintaining airway and respiration should be provided.
