Nortriptyline (sometimes abbreviated NTP in technical documents) is a second-generation tricyclic antidepressant marketed as the hydrochloride under the trade names Sensoval, Aventyl, Pamelor, Norpress, Allegron and Nortrilen. It is used in the treatment of major depression and childhood nocturnal enuresis (bedwetting). In addition, it is sometimes used for chronic illnesses such as chronic fatigue syndrome, chronic pain and migraines, and labile affect in some neurological conditions.

Clinical pharmacology

Nortriptyline is the active metabolite of amitriptyline which is demethylated in the liver, and which inhibits the reuptake of norepinephrine (noradrenaline), and, to a lesser extent, serotonin. Nortriptyline also presents clinically relevant post-synaptic antagonism of muscarinergic and 5HT_2A receptors.^[1] The former is responsible for anticholinergic side-effects, whereas the affinity for 5HT_2A may be responsible for its sleep-improving effect.^[2] In the short run however, nortryptiline may disturb sleep due to its activating effect.

Indications

Nortriptyline is FDA-approved for the treatment of major depression. In the United Kingdom, it may also be used for treating nocturnal enuresis, with courses of treatment lasting no more than three months. It is also used off-label for the treatment of panic disorder, irritable bowel syndrome, migraine prophylaxis and chronic pain or neuralgia modification (particularly TMJ disorder).^[3] It can also aid in quitting smoking, with one study showing a six-month abstinence rate of 14% for subjects receiving nortriptyline compared to 3% for subjects not undergoing pharmacological treatment.^[4] Research has been done suggesting it can reduce symptoms of ADHD.^{[citation needed]} It should be noted, however, that the co-administration of Tricyclic Antidepressants and stimulant ADD medications is highly inadvisable. Due to the blocking effect such medications have on both norepinephrine and serotonin, the stimulant properties of ADD medications can be severely potentiated, resulting in a risk of hypertension, tachycardia, and central overstimulation.^{[citation needed]}

Metabolism

Nortriptyline is metabolised in the liver by hepatic enzyme CYP2D6. Approximately 7 to 10 percent of caucasians are poor metabolisers and might experience more adverse effects, so a lower dosage is often necessary in these individuals.^{[citation needed]} Blood levels of nortriptyline should be obtained during long term treatment to avoid toxicity and optimise response.

Dosage

For depression: Low starting doses are used, increasing as necessary to 75–100 mg (0–50 mg for adolescents and the elderly). Maximum daily dosage is 150 mg.^[5]

For the management of nocturnal enuresis: lower dosages are used with the maximum period of treatment, including gradual withdrawal, being three months and a full examination including electrocardiogram (ECG or EKG) required before further courses.^[5]

For its off-label use for migraine and headache prophylaxis and treating chronic pain: Treatment is started at very low 10 mg once at night to minimise side-effects. The dose is then increased every two weeks if required to a maximum of 150 mg. Nortriptyline is effective for treating migraine-associated vertigo in the same dose titration with 100 mg usually being the maximum necessary dose.

Side effects

The most common side effects include dry mouth, sedation, constipation, and increased appetite. An occasional side effect is a rapid or irregular heartbeat. Alcohol may exacerbate some of its side effects and should be avoided.

However, the incidence of side effects with nortriptyline is lower than with the first-generation tricyclics (e.g., imipramine (Tofranil), amitriptyline (Elavil)).

A study with men has found that treatment with nortriptyline is associated with higher risk of suicidal ideation compared to escitalopram.^[6]

Warnings

Closer monitoring is required for those with a history of cardiovascular disease, stroke, glaucoma, and/or seizures, as well as those that have hyperthyroidism or are receiving thyroid medication.

Excessive consumption of alcohol in combination with nortriptyline therapy may have a potentiating effect, which may lead to the danger of increased suicidal attempts or overdosage, especially in patients with histories of emotional disturbances or suicidal ideation.

Troublesome patient hostility may be aroused by the use of nortriptyline.

Contraindications

In the acute recovery phase after myocardial infarction (e.g., heart attack). As for all tricyclic antidepressants, concurrent use, or failure to allow a two week gap, with monoamine oxidase inhibitors (MAO inhibitors, e.g., phenelzine, tranylcypromine, etc.) may precipitate hyperpyretic crisis and/or severe convulsions; fatalities have occurred.

Overdose

Main article: Tricyclic antidepressant overdose

The symptoms and the treatment of an overdose are largely the same as for the other tricyclic antidepressants.
