How Metaxall works

The mechanism of action of metaxalone in humans has not been established, but may be due to general central nervous system depression.

Toxicity

LD₅₀=775mg/kg (Rat, oral); LD₅₀=1690 mg/kg (Mouse, oral). When determining the LD₅₀ in rats and mice, progressive sedation, hypnosis and finally respiratoryfailure were noted as the dosage increased. In dogs, no LD₅₀ could be determined as the higher doses produced an emetic action in 15 to 30 minutes. Some adverse events associated with the drug include nausea, vomiting, drowsiness and CNS side effects such as dizziness, headache, and irritability.

Food Interaction

Avoid excessive or chronic alcohol consumption. Alcohol may increase the CNS depressant effects of metaxalone.
Take with or without food. The absorption of metaxalone is increased when taken with food, which may increase CNS depression, especially in the elderly.

[Moderate] GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents.

Use in combination may result in additive central nervous system depression and
MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol.

Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.
