Intrathecal baclofen abolishes spasticity in many patients with neurological diseases but there are few studies on its long-term effectiveness. Since 1986 a manually operated subcutaneous pump has been used to deliver baclofen intrathecally in 21 patients with a follow up of at least one year. Most patients had multiple sclerosis and all were wheelchair-bound. Sixteen patients had a complete an...

Immune-complexes play an important role in the inflammatory diseases of the lung. Neutrophil activation mediates immune-complex (IC) deposition-induced acute lung injury (ALI). Components of gamma amino butyric acid (GABA) signaling, including GABA B receptor 2 (GABABR2), GAD65/67 and the GABA transporter, are present in the lungs and in the neutrophils. However, the role of pulmonary GABABR ac...

Metabotropic gamma-aminobutyric acid (GABA) receptors were studied in amphibian retinal ganglion cells using whole cell current and voltage clamp techniques. The aim was to identify the types of receptor present and their mechanisms of action and modulation. Previous results indicated that ganglion cells possess two ionotropic GABA receptors: GABAAR and GABACR. This study demonstrates that they...

The increase in mean arterial pressure evoked by injection of the gamma-aminobutyric acid (GABA)(B) agonist baclofen into the nucleus tractus solitarius (NTS) is greater in spontaneously hypertensive rats and renal wrap chronically hypertensive (CHT) rats compared with normotensive (NT) controls. We report here that the baclofen-induced pressor response (BIPR) is enhanced after acute hypertensi...

Recent preclinical and clinical studies have suggested that baclofen, the prototypic gamma-aminobutyric acid B (GABA(B)) receptor agonist, is a promising pharmacological compound for use in the treatment of alcohol dependence. In particular, baclofen has been found to suppress symptoms of alcohol withdrawal syndrome with an efficacy comparable with that of the 'gold standard' diazepam. Moreover...

Objective: The objective of this observational study was to investigate the effectiveness, safety and tolerability of baclofen in individualised doses for the treatment of alcohol dependence in a sample of patients suffering from additional co-occurring mental disorders. Methods: Fifteen subjects requesting baclofen treatment to achieve abstinence from, or reduction of, alcohol consumption, wer...

Baclofen is a synthetic derivative of GABA and used as muscle relaxant or antispasmodic agent. It in the management various spasticity resulting from conditions such cerebral palsy, spinal cord injuries, stroke. The reported potential adverse effects following overdose are marked impairment consciousness, acute kidney injury, seizures, coma, respiratory failure. Since there no specific antidote...

Release of excitatory transmitter from boutons on crayfish nerve terminals was inhibited by (R,S)-baclofen, an agonist at GABAB receptors. Baclofen had no postsynaptic actions as it reduced quantal content without affecting quantal amplitude. The effect of baclofen increased with concentration producing 18% inhibition at 10 microM; EC50, 50% inhibition at 30 microM; maximal inhibition, 85% at 1...

BACKGROUND The delivery of intrathecal baclofen via pumps is gaining increasing use in the management of intractable spasticity. One of the rare but devastating complications of this method is infection. In the majority of cases, removal of the device is required, despite appropriate intravenous antibiotic therapy. We report a case that highlights the use of intrareservoir teicoplanin to achiev...
