NDRI stands for Norepinephrine-Dopamine Re-uptake Inhibitor.
NDRI drugs are similar to SSRIs and SNRIs, as in, they are said to “inhibit the re-uptake” of certain neurotransmitters (messenger molecules). However, in this case, instead of Serotonin being inhibited, it’s Norepinephrine + Dopamine. Hence the name, Norepinephrine-Dopamine Re-uptake Inhibitor (NDRI).
So, what does that mean in plain english?!
Well, this act of inhibiting the natural recycling process of Norepinephrine + Dopamine is said to increase the availability of these neurotransmitters (messenger molecules) within the brain, which is believed to alleviate the ‘symptoms’ of depression.

NDRI Drugs List
Norepinephrine–dopamine re-uptake inhibitors (NDRIs) are used for clinical depression, attention deficit hyperactivity disorder (ADHD), narcolepsy, smoking cessation and as anti-parkinson agents.
Here’s a list of some commonly prescribed NDRI drugs.
- Bupropion – Wellbutrin – Zyban – Elontril – Budeprion – Aplenzin – Voxra – Forfivo – Prexaton – Quomem – Zyntabac – Carmubine
- Dexmethylphenidate – Focalin – Attenade – Concerta (Lithuania)
- Methylphenidate – Concerta – Ritalin – Metadate CD – Medikinet – Matoride XL – Equasym – Medicebran – Daytrana – Difumenil – Biphentin – Aptensio XR – Methylin – Motiron – Quasym – Quillivant XR (NOTE: Known to act as a DNRI dopamine-norepinephrine reuptake inhibitor. In other words, it acts on dopamine more than norepinephrine).
Most Common Side Effects of NDRI’s

- Nausea / vomiting
- Feeling agitated, shaky or anxious
- Diarrhoea or constipation
- Dizziness / Lightheadedness

- Increased risk of gastrointestinal (stomach/intestinal) bleeding
- Increased risk of Serotonin Syndrome.
NB. Although there are no documented cases of Serotonin Syndrome following Bupropion/Wellbutrin/Zyban ingestion alone in the literature, the ability of Bupropion/Wellbutrin/Zyban to potentiate serotonin levels and lead to Serotonin Syndrome is known.
Antidepressant drugs can interact with other medications, foods and natural supplements (for example; St Johns Wort) which may increase the risk of Serotonin Syndrome, so be sure to speak to your doctor or healthcare provider to ensure there’s no negative interactions.

NOTE: Always consult your healthcare provider to ensure the information displayed on the Drug Interactions page applies to your personal circumstances. Always check with your healthcare provider to determine if any adjustments to your medications are needed.
WARNING: *** NEVER stop an antidepressant drug without first consulting your healthcare provider. Suddenly stopping an antidepressant drug can cause adverse effects.***
