Another patient who ingested 9 000 mg of bupropion immediate release and 300 mg of tranylcypromine experienced a grand mal seizure and recovered without further sequelae.Since introduction, overdoses of up to 17 500 mg of the immediate release formulation of bupropion have been reported. These symptoms were sometimes of sufficient magnitude to require discontinuation of bupropion, or concurrent treatment with sedative/hypnotic drugs.Psychosis, Confusion, and Other Neuropsychiatric Phenomena: Patients treated with bupropion have been reported to show a variety of neuropsychiatric signs and symptoms including delusions, hallucinations, psychosis, concentration disturbance, paranoia and confusion.
The mechanism of bupropion’s antidepressant activity is unknown but appears to be mediated by noradrenergic (and possibly dopaminergic), rather than serotonergic mechanisms. Preclinical studies have shown that bupropion blocks noradrenalin (NA) reuptake and dopamine (DA) reuptake. Detectable levels of hydroxybupropion are not observed with CYP1A1 and CYP2D6 isozymes. Oxidation of the bupropion side chain results in the formation of a glycine conjugate of meta-chlorobenzoic acid, which is then excreted as the major urinary metabolite. Given the wide variability among individuals and their capacity to metabolize and eliminate drugs, the disproportionate increase in seizure incidence with dose incrementation calls for caution in dosing.The risk of seizure occurring with bupropion use appears to be associated with the presence of predisposing risk factors. Reported adverse events were classified using a COSTART-based Dictionary.Events Observed During Development and Postmarketing Experience with the Immediate-Release Formulation of Bupropion: The following adverse events have been reported in clinical trials and postmarketing clinical experience with the immediate-release formulation of bupropion. In human studies of abuse liability, individuals experienced with drugs of abuse reported that bupropion produced a feeling of euphoria and desirability. Other serious reactions reported with overdoses of bupropion alone included hallucinations, loss of consciousness and sinus tachycardia. Therefore caution should be used when treating patients with predisposing factors which increase the risk of seizures, including: history of head trauma or prior seizure; CNS tumor; excessive use of alcohol; abrupt withdrawal from alcohol, benzodiazepines or other sedatives; addiction to opiates, cocaine, or stimulants; use of concomitant medications that lower seizure threshold (e.g., antipsychotics, antidepressants, lithium, theophylline or systemic steroids); use of over-the-counter stimulants or anorectics; diabetes treated with oral hypoglycemics or insulin.The risk of seizure may be minimized if the total daily dose of bupropion does not exceed 300 mg (the maximum recommended dose), and no single dose of bupropion exceeds 150 mg, in order to avoid high peak concentrations of buproprion and/or its metabolites.Allergic Reactions: Anaphylactoid reactions characterized by symptoms such as pruritus, urticaria, angioedema, and dyspnea requiring medical treatment have been reported in clinical trials with bupropion at a rate of 1 to 3 per thousand.
