Soma - Comprehensive Usage Guide: instructions, indications, composition, side effects
Composition
- Active Ingredient: Carisoprodol
- Excipients: May include microcrystalline cellulose, magnesium stearate, starch, and other inactive ingredients depending on the formulation.
Official Forms
Tablets: Available in various strengths, including 250 mg and 350 mg tablets.
Pharmacological Group
Soma belongs to the pharmacological group of muscle relaxants (ATC code: M03BA02).
Pharmacological Properties
- Pharmacodynamics: Carisoprodol acts centrally as a muscle relaxant, exerting its effects by disrupting neuronal communication within the reticular formation and spinal cord. It does not directly relax tense skeletal muscles but rather affects the perception of pain and muscle spasms.
- Pharmacokinetics: Carisoprodol is rapidly absorbed after oral administration, with peak plasma concentrations achieved within 1 to 2 hours. It is metabolized in the liver by the cytochrome P450 enzyme system and excreted primarily in the urine.
Indications
Soma is indicated for the relief of discomfort associated with acute, painful musculoskeletal conditions.
Contraindications
Soma is contraindicated in individuals with:
- Hypersensitivity to carisoprodol or any component of the formulation
- Porphyria
- Acute intermittent porphyria
- Known or suspected substance abuse disorders
Interactions
Carisoprodol may interact with:
- CNS depressants, including alcohol, benzodiazepines, opioids, and other sedative-hypnotics, leading to additive CNS depression and respiratory depression
- Drugs that inhibit CYP2C19 enzyme activity, potentially increasing carisoprodol levels and toxicity
Specifics of Use
- Soma should be taken orally with or without food as directed by a healthcare provider.
- The recommended dosage for adults is 250 mg to 350 mg three times daily and at bedtime for up to two to three weeks.
- Prolonged use beyond two to three weeks is not recommended due to the risk of tolerance, dependence, and withdrawal symptoms.
Pregnancy and Breastfeeding
- Soma should be used with caution during pregnancy, especially during the first trimester, and only if the potential benefits outweigh the risks.
- It is excreted in breast milk, and breastfeeding is not recommended during carisoprodol treatment due to the potential risk to the infant.
Dosage and Administration
- The dosage of Soma should be individualized based on the patient’s response to therapy and tolerance of side effects.
- Elderly patients and those with hepatic impairment may require lower initial doses and gradual titration.
Overdose
In case of overdose, supportive measures should be initiated, and medical attention should be sought immediately. Symptoms of carisoprodol overdose may include drowsiness, dizziness, confusion, respiratory depression, and coma.
Side Effects
Common side effects of Soma may include:
- Drowsiness
- Dizziness
- Headache
- Nausea
- Vomiting
Storage and Shelf Life
Soma tablets should be stored at controlled room temperature (20-25°C) in a dry place, protected from light and moisture. The expiration date should be checked before use.
