Nartex (Sodium Oxybate)

Sodium Oxybate, the active ingredient in Nartex, is a GABA_B receptor agonist presented as an oral formulation for oral use. It is approved in the EU for the treatment of narcolepsy with cataplexy and excessive daytime sleepiness in adult patients.

GNH USA supplies Nartex as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company provides quality‑assured product batches under strict GMP conditions to meet the needs of healthcare providers in diverse markets and supports reliable logistics for timely delivery.

Nartex (sodium oxybate) is used in the central nervous system disorder category of narcolepsy. - Narcolepsy with cataplexy: reduces cataplexy episodes and improves nighttime sleep quality. - Excessive daytime sleepiness (EDS) associated with narcolepsy: decreases daytime sleepiness and improves wakefulness. - Fragmented nighttime sleep in narcolepsy: enhances slow‑wave sleep and reduces sleep fragmentation.

Sodium Oxybate may cause a range of adverse reactions, which are categorized by frequency and severity.

Common Side Effects: - Nausea: mild to moderate stomach upset. - Headache: transient cranial discomfort. - Dizziness: sensation of lightheadedness. - Nasal congestion: blockage or runny nose. - Fatigue: increased tiredness after dosing.

Serious or Rare Side Effects: - Respiratory depression: reduced breathing effort, potentially life‑threatening. - Seizures: occurrence of convulsive episodes. - Severe hypotension: marked drop in blood pressure. - Allergic reactions: rash, itching, swelling, or anaphylaxis. - Abuse potential: risk of dependence or misuse.

When prescribing sodium oxybate, clinicians should consider several safety precautions to minimize risk. - Contraindication: avoid use in patients with a known hypersensitivity to sodium oxybate. - Respiratory disorders: monitor closely in individuals with sleep‑disordered breathing or COPD. - Concomitant CNS depressants: limit use with alcohol, benzodiazepines, or opioids. - Pregnancy: use only if the potential benefit justifies the potential risk, as safety data are limited. - Driving and machinery: advise patients that the drug may impair alertness and should not operate vehicles until they know its effects. - Store at ambient temperature: keep below 25 °C in the original container, protect from moisture and light.

Sodium oxybate can interact with other medicines, and interactions are classified by their clinical significance.

Major Interactions (Avoid): - Alcohol: combined use can cause profound respiratory depression and excessive sedation. - Opioids: additive CNS depression may lead to life‑threatening outcomes. - Benzodiazepines: heightened sedative effect increases risk of overdose.

Moderate Interactions (Monitor Closely): - Antidepressants (e.g., SSRIs, SNRIs): may increase risk of serotonin syndrome. - Antihypertensives: sodium oxybate can enhance blood pressure‑lowering effects. - Anticonvulsants: possible alteration of seizure threshold.
