✔️ Indications:

Treats diseases that cause hyperkinetic motor disorders (such as jerky, irregular, uncontrollable movements) associated with Huntington's chorea (an inherited neurodegenerative disease) in affected individuals

✔️ Pharmacology

• Tetrabenazine reversibly inhibits human vesicular monoamine transporter type 2 (VMAT2), which leads to decreased uptake of monoamines (such as dopamine, serotonin, norepinephrine, and histamine) into synaptic vesicles.
• This inhibition results in the depletion of monoamine stores from nerve terminals.
• The mechanism is similar to reserpine but with less peripheral activity and is shorter-acting.

✔️ Dosage & Administration of Tetraben 12.5mg Tablet

Adult Dose:

For Huntington's Disease (chorea associated):

• Start with 12.5 mg orally once daily.
• After one week, increase to 12.5 mg every 12 hours.
• Slowly titrate by weekly intervals of 12.5 mg/day to find a dose that reduces chorea and is well tolerated.
• If the daily dose is between 37.5 to 50 mg, administer in divided doses every 8 hours.
• For elderly patients, start with 12.5 mg daily and increase gradually.
• If a dose higher than 50 mg/day is needed, test and genotype to determine metabolizer status. The maximum recommended daily dose is 100 mg/day or 37.5 mg per dose.

For moderate to severe tardive dyskinesia:

• Start with 12.5 mg daily and increase gradually based on response.

Child Dose:

• Safety and efficacy have not been established in children, so no specific dosing guidelines are available.

Special Populations:

• Tetrabenazine is contraindicated in patients with hepatic impairment, as dose adjustment cannot ensure safe use.

✔️ Interaction

Tetraben 12.5mg Tablet not be given with or within 14 days of discontinuation of MAOI therapy. It may block the action of reserpine and decrease the effects of levodopa. There is an increased risk of extrapyramidal side effects when given certain medications like amantadine, metoclopramide, and antipsychotics.

✔️ Contraindications

Hypersensitivity. Lactation. Hepatic impairment. Patients who are actively suicidal, or who have untreated or inadequately treated depression.

✔️ Pregnancy & Lactation

Pregnancy:

• There is limited data on the developmental risk associated with Tetrabenazine use in pregnant women.
• Administration of Tetrabenazine to rats throughout pregnancy and lactation increased stillbirths and postnatal offspring mortality.
• The potential risks and benefits of Tetrabenazine use during pregnancy should be carefully considered, and treatment should only be initiated if necessary.

Lactation:

• There is no data on the presence of Tetrabenazine or its metabolites in human milk, its effects on breastfed infants, or milk production.
• The developmental and health benefits of breastfeeding should be weighed against the potential adverse effects on the breastfed infant or underlying maternal condition.

✔️ Precautions & Warnings:

• Tetrabenazine may exacerbate symptoms of parkinsonism, so caution should be exercised, especially when engaging in activities that require mental alertness, such as driving or operating machinery.
• Pregnant patients should use Tetrabenazine with caution, and the potential risks and benefits should be discussed with a healthcare provider.
• Patients with Huntington's disease may have an increased risk of depression and suicidal thoughts or behavior (suicidality) while taking Tetrabenazine.
• It's essential to monitor for the emergence or worsening of depression, suicidality, or unusual changes in behavior, especially in patients with a history of depression or prior suicide attempts or ideation.
