Background: Epilepsy of infancy with migrating focal seizures (EIMFS) is one of the early-onset epileptic encephalopathies resistant to antiepileptic drugs, therefore carrying an extremely poor neurodevelopmental outcome. KCNT1, encoding for a sodium-activated
The effects of dextromethorphan (DM), a nonopioid antitussive and a functional N-methyl-D-aspartate (NMDA) antagonist, on expression and development of amygdaloid kindled seizures were examined. The maximum anticonvulsant effect of DM (30 mg/kg) on fully kindled seizures appeared within 30 min of
Dextromethorphan (DM), a non-prescription antitussive, has anticonvulsant properties and antagonizes N-methyl-D-aspartate (NMDA) receptor-mediated responses in rat spinal and cortical neurons. The effects of daily intraperitoneal injections of DM on amygdala-kindled seizures were examined. DM was
We report a 35-year-old man who was referred to our hospital with generalized convulsion and mixed acidosis presumably caused by abuse of SS-BRON tablets, an over-the-counter (OTC) antitussive medication sold in Japan. These tablets contain dihydrocodeine phosphate, methylephedrine,
The anticonvulsants diazepam (1-10 mg/kg) and phenobarbital (30-100 mg/kg) protected against lethality without altering clonic convulsions induced by 75 mg/kg cocaine (CD100) in male Swiss Webster mice. In contrast, the non-competitive N-methyl-D-aspartate (NMDA) antagonists, MK-801 (dizocilpine)
Vadocaine hydrochloride (2',4'-dimethyl-6'-methoxy-3-(2-methylpiperidyl) propionanilide hydrochloride, OR K-242-HCl; INN: vadocaine) is a novel antitussive compound which is effective in several animal models at doses of 2.5-6 mg/kg. It has both central and peripheral local anaesthetizing
Camphor is a cyclic ketone of the hydro aromatic terpene group. Today it is frequently used as a prescription or non-prescription topical antitussive, analgesic, anesthetic and antipruritic agent. Camphor which is considered an innocent drug by parents and physicians is a common household item which
The antitussives dextromethorphan (DM), carbetapentane (CBP), and caramiphen (CM) are known to have anti-convulsant properties. They were given individually to guinea pigs prior to poisoning with 2 x LD50 soman to test their efficacy against organophosphorus-induced convulsions, brain damage, and
The effect of the non-opioid antitussive caramiphen was studied in the rat maximal electroshock test. Caramiphen produced a dose- and time-dependent blockade of tonic hindlimb extension and was nearly twice as potent as the prototypical anticonvulsant drug diphenylhydantoin. Pretreatment with a
Dextromethorphan, widely used as an antitussive, has recently been shown to protect animals against maximal electroshock and excitatory amino acid (N-methyl-D-aspartate)-induced convulsions. Its protective efficacy against theophylline-induced seizures was determined in this investigation in view of
We performed a double-blind, crossover, add-on study of the antitussive agent dextromethorphan (DM 120 mg/d) as therapy for seizures on 9 patients suffering from severe complex partial seizures. DM had no significant influence on key laboratory values, nor on anticonvulsant drug levels. Side effects
Millions of individuals worldwide suffer from epilepsy, and up to 25% of patients have seizures that are resistant to currently available antiepileptic drugs. Hence, there continues to be a need for more seizure medications that are effective yet tolerable. Levodropropizine (LVDP) is Interest in dextromethorphan (DM) has been renewed because of its anticonvulsant and neuroprotective properties. However, DM at supra-antitussive doses can produce psychotomimetic effects in humans. Recently, we demonstrated that DM exerts psychotropic effects in mice [Neurosci. Lett. 288 (2000) 76,
