Drug Uses

Soma is a muscle relaxant used to relieve the pain and stiffness of muscle spasms and discomfort due to strain and sprain.

How Taken

Soma is taken orally. The usual adult dosage of soma is one 350 mg tablet, three times daily and at bedtime. Usage in patients under age 12 is not recommended. It is recommended that you take Soma with food, or with milk, to minimize the likelihood that you will suffer an upset stomach as a result of taking the medication.

Warnings/Precautions

Do not take Soma if you have acute intermittent porphyria. Before taking Soma, tell your doctor if you have kidney or liver disease. You may need a lower dose or special monitoring during your therapy. It is not known whether Soma will harm an unborn baby. Do not take Soma without first talking to your doctor if you are pregnant. It is also not known whether Soma passes into breast milk. Do not take Soma without first talking to your doctor if you are breast-feeding a baby. Soma is not approved for use in children younger than 12 years of age.

Missed Dose

If you miss a Soma dose, take it as soon as remembered if it is within an hour or so. If you do not remember until later, skip the missed dose and resume your usual dosing schedule. Do not 'double-up' the Soma dose to catch up.

Possible Side Effects

Soma may cause dizziness, vertigo, ataxia, tremor, agitation, irritability, headache, depressive reactions, syncope, and insomnia. Allergic or idiosyncratic reactions occasionally develop. They are usually seen within the period of the first to fourth dose in patients having had no previous contact with the drug. Skin rash, erythema multiforme, pruritus, eosinophilia, and fixed drug eruption with cross reaction to meprobamate have been reported with Soma. Severe reactions have been manifested by asthmatic episodes, fever, weakness, dizziness, angioneurotic edema, smarting eyes, hypotension, and anaphylactoid shock.

Storage

Store at controlled room temperature 15°-30°C (59°-86°F). Dispense in a tight container.

Overdose

Seek emergency medical attention. Symptoms of a Soma overdose include low blood pressure (weakness, fainting, confusion), decreased breathing, and unconsciousness.

More Information

Use caution when driving, operating machinery, or performing other hazardous activities. Soma may cause dizziness or drowsiness. If you experience dizziness or drowsiness, avoid these activities. Use alcohol cautiously. Alcohol may increase drowsiness and dizziness while you are taking Soma.

Neuromagnetic activation of primary and secondary somatosensory cortex following tactile-on and tactile-off stimulation
Conclusions: The somatosensory evoked magnetic fields waveforms elicited by the two tactile stimuli (tactile-on and tactile-off stimuli) with a mechanical stimulator were strikingly similar. These mechanical stimuli elicited both contralateral SI and ipsilateral SII activities.Significance: Tactile stimulation with a mechanical stimulator provides new possibilities for experimental designs in studies of the human mechanoreceptor system.

Antidepressant fluoxetine suppresses neuronal growth from both vertebrate and invertebrate neurons and perturbs synapse formation between Lymnaea neurons
In this study, using mammalian cortical neurons, a dorsal root ganglia cell line (F11 cells) and identified Lymnaea stagnalis neurons, we provide the first direct and unequivocal evidence that clinically relevant concentrations of Fluoxetine induce growth cone collapse and neurite retraction of both serotonergic and non-serotonergic neurons alike in a dose-dependent manner. Using intracellular recordings and calcium imaging techniques, we further demonstrate that the mechanism underlying Fluoxetine-induced effects on neurite retraction from Lymnaea neurons may involve lowering of intracellular calcium and a subsequent retardation of growth cone cytoskeleton. Using soma[ndash]soma synapses between identified presynaptic and postsynaptic Lymnaea neurons, we provide further direct evidence th...

Dynamics of peptidergic secretory granule transport are regulated by neuronal stimulation
Conclusions: Under basal conditions, LDCVs move faster away from the soma than toward the soma, but fewer LDCVs travel anterograde than retrograde. Stimulation decreases average anterograde velocity and increases granule pausing. Data from antibody uptake, quantification of enzyme secretion and appearance of pHluorin fluorescence demonstrate distributed release of peptides all along the axon, not just at terminals.

Weekly Intravenous and Intraperitoneal Paclitaxel Combined with S-1 for Malignant Ascites due to Advanced Gastric Cancer.
Authors: Kitayama J, Ishigami H, Kaisaki S, Hidemura A, Kato M, Otani K, Kamei T, Soma D, Miyato H, Yamashita H, Nagawa H Malignant ascites caused by gastric cancer are chemotherapy resistant and carry a poor prognosis. The efficacy of a regimen including intraperitoneal paclitaxel (PTX) was evaluated in 33 gastric cancer patients with ascetic fluid in the peritoneal cavity diagnosed with computed tomography (CT) scanning. Synchronous administration of intravenous (50 mg/m(2)) and intraperitoneal (20 mg/m(2)) PTX was performed via a subcutaneously placed intraperitoneal catheter on days 1 and 8, and S-1 was administered twice daily at 80 mg/m(2)/day for 14 consecutive days from day 1 to day 14, followed by 7 days of rest. The ascitic fluid volume was calculated with NIH Image J softwar...

L-type calcium channels and cytochrome b(5) reductase are components of protein complexes tightly associated with lipid rafts microdomains of the neuronal plasma membrane.
Authors: Marques-da-Silva D, Samhan-Arias AK, Tiago T, Gutierrez-Merino C The presence of cytosolic calcium microcompartments in neurons is well established. L-type voltage calcium channels play a leading role in the rise of cytosolic calcium in the neuronal soma and are sensitive to redox modulation. In a recent work [Samhan-Arias, A.K., García-Bereguiaín, M.A., Martín-Romero, F.J. and Gutiérrez-Merino, C. (2009) Mol. and Cell. Neurosci. 40, 14-26], we have shown that cytochrome b(5) reductase, whose deregulation leads to an overshot of superoxide anion production at the neuronal plasma membrane that triggers apoptosis in primary cultures of cerebellar granule neurons in culture, forms a large mesh of redox centres associated with lipid rafts in these neurons. In t...
