Bupropion D9
Vue d'ensemble
Description
Bupropion D9 is a deuterated form of bupropion, a norepinephrine and dopamine reuptake inhibitor commonly used in the treatment of major depressive disorder, seasonal affective disorder, and as an aid for smoking cessation . The deuterated form, this compound, is used primarily as an internal standard in analytical chemistry due to its stable isotopic labeling, which helps in the quantification of bupropion levels in biological matrices .
Mécanisme D'action
Target of Action
Bupropion D9 primarily targets the norepinephrine transporter (NET) and the dopamine transporter (DAT) . These transporters are responsible for the reuptake of the neurotransmitters norepinephrine and dopamine from the synaptic cleft . This compound also acts as a non-competitive nicotine receptor antagonist .
Mode of Action
This compound exerts its pharmacological effects by weakly inhibiting the enzymes involved in the uptake of the neurotransmitters norepinephrine and dopamine from the synaptic cleft . This action prolongs the duration of these neurotransmitters within the neuronal synapse, leading to the downstream effects of these neurotransmitters . When used as an aid to smoking cessation, this compound is thought to confer its anti-craving and anti-withdrawal effects by inhibiting dopamine reuptake, which is thought to be involved in the reward pathways associated with nicotine .
Biochemical Pathways
This compound is hydroxylated to its primary active metabolite, hydroxybupropion, by the cytochrome P450 enzyme CYP2B6 . In vitro data suggest the existence of alternative hydroxylation pathways mediated by the highly polymorphic enzyme CYP2C19 . The majority of bupropion is cleared via reduction to threohydrobupropion (66%) and erythrohydrobupropion (6%) .
Pharmacokinetics
Following oral administration of bupropion hydrochloride tablets, peak plasma bupropion concentrations are usually achieved within 2 hours . Bupropion is extensively and rapidly absorbed in the gastrointestinal tract but experiences extensive first pass metabolism rendering its systemic bioavailability limited . Absorption is suggested to be between 80 and 90% .
Result of Action
The inhibition of norepinephrine and dopamine reuptake by this compound results in prolonged neurotransmitter action within the neuronal synapse, leading to increased locomotor activity and increased rates of responding in various schedule-controlled operant behavior tasks .
