Carisoprodol is used as an adjunct to rest, physical therapy, analgesics, and other measures for the relief of discomfort associated with acute, painful musculoskeletal conditions. /Included in US product label/
American Society of Health System Pharmacists; AHFS Drug Information 2010. Bethesda, MD. (2010), p. 1391
Occasionally, patients may have allergic or idiosyncratic reactions to carisoprodol. In patients who have not received carisoprodol previously, these reactions are usually evident by the time of the fourth dose of the drug. Idiosyncratic reactions may be characterized by extreme weakness, transient quadriplegia, dizziness, ataxia, temporary loss of vision, diplopia, mydriasis, dysarthria, agitation, euphoria, confusion, and disorientation. These symptoms usually subside within several hours; however, symptomatic and supportive therapy, including hospitalization, may be necessary in some patients. Rash, erythema multiforme, pruritus, urticaria, eosinophilia, and fixed drug eruption have occurred in patients receiving carisoprodol who previously had similar reactions to meprobamate. Severe allergic reactions have been characterized by asthmatic episodes, fever, weakness, dizziness, angioedema, smarting eyes, hypotension, and anaphylactic shock.
American Society of Health System Pharmacists; AHFS Drug Information 2010. Bethesda, MD. (2010), p. 1391
The most frequent adverse effects of carisoprodol are drowsiness and dizziness. Other adverse CNS effects include vertigo, ataxia, tremor, agitation, irritability, headache, depressive reactions, syncope, and insomnia.
American Society of Health System Pharmacists; AHFS Drug Information 2010. Bethesda, MD. (2010), p. 1391
Because carisoprodol is metabolized by the liver and excreted by the kidneys, the drug should be used with caution in patients with impaired hepatic or renal function. Patients should be warned that carisoprodol may impair ability to perform hazardous activities requiring mental alertness or physical coordination such as operating machinery or driving a motor vehicle.
American Society of Health System Pharmacists; AHFS Drug Information 2010. Bethesda, MD. (2010), p. 1391
Adverse GI effects of carisoprodol include nausea, vomiting, hiccups, increased bowel activity, and epigastric distress. Adverse cardiovascular effects include tachycardia, postural hypotension, and facial flushing. Although a causal relationship to carisoprodol has not been established, leukopenia and pancytopenia have occurred rarely in patients receiving carisoprodol along with other drugs.

Carisoprodol is indicated for the relief of discomfort related to acute, painful musculoskeletal conditions. **Important limitations of use**: Should only be used for acute treatment periods up to two or three weeks Adequate evidence of effectiveness for more prolonged use has not been established Not recommended in pediatric patients less than 16 years of age
FDA Label
Carisoprodol is a centrally acting skeletal muscle relaxant that does not act directly on skeletal muscle but acts directly on the central nervous system (CNS). This drug relieves the painful effects of muscle spasm. A metabolite of carisoprodol, _meprobamate_, possesses both anxiolytic and sedative properties. Clinical studies have shown that this drug causes impairment of psychomotor performance in neuropsychological tests.
Muscle Relaxants, Central
A heterogeneous group of drugs used to produce muscle relaxation, excepting the neuromuscular blocking agents. They have their primary clinical and therapeutic uses in the treatment of muscle spasm and immobility associated with strains, sprains, and injuries of the back and, to a lesser degree, injuries to the neck. They have been used also for the treatment of a variety of clinical conditions that have in common only the presence of skeletal muscle hyperactivity, for example, the muscle spasms that can occur in MULTIPLE SCLEROSIS. (From Smith and Reynard, Textbook of Pharmacology, 1991, p358) (See all compounds classified as Muscle Relaxants, Central.)

Absorption
The absolute bioavailability of carisoprodol has not yet been established. The mean time to peak plasma concentrations (Tmax) of this drug was about 1.5-2 hours in clinical studies. Co-administration of a fatty meal with carisoprodol (350 mg tablet) had no impact on carisoprodol pharmacokinetics.
Route of Elimination
Carisoprodol is eliminated by the kidneys as well as other routes. The half-life of meprobamate is approximately 10 hours.
Volume of Distribution
0.93 to 1.3 L/kg, according to 4 different clinical studies.
Clearance
Following an oral dose of carisoprodol, the oral clearance (Cl/F) was 39.52 16.83 L/hour.
Carisoprodol crosses the placenta. The drug distributes into milk in concentrations 2-4 times higher than concurrent maternal plasma concentrations.
American Society of Health System Pharmacists; AHFS Drug Information 2010. Bethesda, MD. (2010), p. 1391
Plasma concentrations of carisoprodol required for sedative, skeletal muscle relaxant, or toxic effects are not known. One manufacturer reports that plasma concentrations of 4-7 ug/mL were attained in 4 hours following oral administration of 350 mg of carisoprodol to healthy adults. Following usual therapeutic dosages, the onset of action is usually within 30 minutes and the duration of action is 4-6 hours.
American Society of Health System Pharmacists; AHFS Drug Information 2010. Bethesda, MD. (2010), p. 1391
The objective of this study was to quantify the excretion of carisoprodol and meprobamate in human milk and estimate the dose received by breast-fed infants. The concentrations of carisoprodol and meprobamate were measured in breast milk on 4 consecutive days at steady-state conditions in one woman using carisoprodol 2100 mg/d. The average milk concentrations were 0.9 microg/mL for carisoprodol and 11.6 ug/mL for meprobamate. Based on the milk concentrations measured, the absolute dose ingested by an exclusively breast-fed infant could be estimated at 1.9 mg/kg per day, and the relative dose would be 4.1% of the weight-adjusted maternal dose. ...

The main pathway of carisoprodol is liver metabolism is by the cytochrome enzyme CYP2C19 to form meprobamate. This enzyme exhibits genetic polymorphism, which may affect the metabolism of this drug.

Carisoprodol is metabolized in the liver; animal studies indicate the drug may induce liver microsomal enzymes. Animal studies also indicate that the drug is excreted in urine, principally as hydroxycarisoprodol and hydroxymeprobamate, and to a lesser extent as meprobamate; trace amounts of carisoprodol are excreted unchanged in urine. The drug may be removed by hemodialysis or peritoneal dialysis.

Carisoprodol is a muscle relaxant analgesic, which has an active metabolite i.e. meprobamate. We conducted an open three-panel single-dose administration study with 15 healthy volunteers: five poor metabolizers of mephenytoin, five poor metabolizers of debrisoquine and five extensive metabolizers of both substrates. The aim was to investigate if the elimination of carisoprodol and meprobamate is dependent on the two metabolic polymorphisms of mephenytoin and debrisoquine. The subjects were given single oral doses of 700 mg carisoprodol and 400 mg meprobamate on separate occasions. The disposition of carisoprodol was clearly correlated to the mephenytoin hydroxylation phenotype. The mean serum clearance of carisoprodol was four times lower in poor metabolizers of mephenytoin than in extensive metabolizers, which confirms the hypothesis from our previous study that N-dealkylation of carisoprodol cosegregates with the mephenytoin hydroxylation polymorphism. However, mean serum clearance of meprobamate did not differ between the two groups. Also, polymorphic debrisoquine hydroxylation did not influence the elimination of carisoprodol or meprobamate. Poor metabolizers of mephenytoin thus have a lower capacity to metabolize carisoprodol and may therefore have an increased risk of developing concentration dependent side-effects such as drowsiness and hypotension, if treated with ordinary doses of carisoprodol.

The mechanism of action of carisoprodol in relieving discomfort associated with acute painful musculoskeletal conditions has not been confirmed. In studies using animal models, the muscle relaxation that is induced by carisoprodol is associated with a change in the interneuronal activity of the spinal cord and of the descending reticular formation, located in the brain. The abuse potential of this drug is attributed to its ability to alter GABAA function. This drug has been shown to modulate a variety of GABAA receptor subunits. GABAA receptor modulation can lead to anxiolysis due to inhibitory effects on neurotransmission.
Carisoprodol is a CNS depressant which has sedative and skeletal muscle relaxant effects. The precise mechanism of action of the drug is not known. The skeletal muscle relaxant effects of orally administered carisoprodol are minimal and are probably related to its sedative effect. The drug does not directly relax skeletal muscle and, unlike neuromuscular blocking agents, does not depress neuronal conduction, neuromuscular transmission, or muscle excitability. In animals, carisoprodol appears to modify central perception of pain without abolishing peripheral pain reflexes and to have slight antipyretic activity, but these effects have not been demonstrated in clinical studies.
American Society of Health System Pharmacists; AHFS Drug Information 2010. Bethesda, MD. (2010), p. 1391
Carisoprodol is an increasingly abused, centrally-acting muscle relaxant. Despite the prevalence of carisoprodol abuse, its mechanism of action remains unclear. Its sedative effects, which contribute to its therapeutic and recreational use, are generally attributed to the actions of its primary metabolite, meprobamate, at GABA(A) receptors (GABA(A)R). Meprobamate is a controlled substance at the federal level; ironically, carisoprodol is not currently classified as such. Using behavioral and molecular pharmacological approaches, we recently demonstrated carisoprodol, itself, is capable of modulating GABA(A)R function in a manner similar to central nervous system depressants. Its functional similarities with this highly addictive class of drugs may contribute to the abuse potential of carisoprodol. The site of action of carisoprodol has not been identified; based on our studies, interaction with benzodiazepine or barbiturate sites is unlikely. ...
