No data available for drug.
Actions and Spectrum:
zuclopenthixol is an antipsychotic medication that belongs to the class of drugs known as thioxanthenes. It is primarily used to treat schizophrenia and other psychotic disorders.
The mechanism of action of zuclopenthixol is not fully understood, but it is generally believed to work by blocking dopamine receptors in the brain. Dopamine is a neurotransmitter that is generally involved in the regulation of behavior, mood, and cognition. By blocking dopamine receptors, zuclopenthixol can help to reduce the symptoms of psychosis, like hallucinations and delusions.
zuclopenthixol is also thought to have some activity at other receptors in the brain, including serotonin and adrenergic receptors. This may contribute to its overall effectiveness in treating psychotic disorders.
The spectrum of zuclopenthixol refers to the range of symptoms and conditions it can treat. As an antipsychotic medication, zuclopenthixol is primarily used to treat symptoms of psychosis, including hallucinations, delusions, disordered thinking, and agitation. It may also treat other psychiatric disorders like bipolar disorder and severe anxiety.

Black Box Warning:
zuclopenthixol has a black box warning, the most severe warning that the US Food and Drug Administration (FDA) can require. The black box warning for zuclopenthixol relates to an enhanced mortality risk in elderly patients with dementia-related psychosis.
Older patients with dementia-related psychosis who are treated with antipsychotic medications like zuclopenthixol are at an enhanced risk of death compared to those who are not treated with these medications. This risk appears to be highest in the first few weeks of treatment.
zuclopenthixol is not approved for the treatment of dementia-related psychosis, and the black box warning advises healthcare professionals to carefully consider the risks and benefits of using antipsychotic medications in elderly patients with this condition.
The black box warning also advises that zuclopenthixol should be generally used cautiously in patients with a history of seizures, as it may lower the seizure threshold and increase the risk. Additionally, zuclopenthixol may cause other side effects, including sedation, weight gain, and movement disorders. Healthcare professionals should monitor patients closely for these side effects, adjust the dosage, or switch to a different medication if necessary.
Contraindication/Caution:
Contraindication
zuclopenthixol has several contraindications, so it should not be used in certain patients or conditions. These contraindications include:
Hypersensitivity: zuclopenthixol should not be used in patients with known hypersensitivity/allergy to the drug or its components.
Central Nervous System Depression: zuclopenthixol can cause sedation and effects on the central nervous system.
Bone Marrow Suppression: zuclopenthixol may cause bone marrow suppression, which can reduce the production of blood cells.
Prolactin-Dependent Tumors: zuclopenthixol may increase the production of the hormone prolactin, which can stimulate the growth of prolactin-dependent tumors.
Severe Liver Disease: zuclopenthixol is primarily metabolized in the liver, and patients with severe liver disease might not generally able to metabolize the medicationproperly.
Concomitant Use with Certain Medications: zuclopenthixol should not be used concomitantly with medications that can prolong the QT interval, like class Ia and III antiarrhythmics, as it may increase the risk of serious cardiac arrhythmias.
Caution
zuclopenthixol has several cautions, which means it should be used cautiously in certain patients or conditions. These cautions include:
Cardiovascular Disease: zuclopenthixol can cause heart rhythm and blood pressure changes.
Diabetes: zuclopenthixol may cause an increase in blood sugar levels, which can get problematic for patients with diabetes. Therefore, patients with diabetes taking zuclopenthixol should monitor their blood sugar levels regularly.
Parkinson’s Disease: zuclopenthixol may worsen the symptoms of Parkinson’s disease, a neurological disorder generally characterized by tremors, rigidity, and difficulty with movement.
Seizure Disorders: zuclopenthixol may lower the seizure threshold and increase the risk of seizures.
Renal Impairment: zuclopenthixol is primarily eliminated by the kidneys, and patients with renal impairment may not be able to eliminate the drug properly.
Respiratory Disease: zuclopenthixol can cause respiratory depression, which can be problematic for patients with respiratory disease.
Pregnancy consideration: Studies with animal reproduction reported adverse events in newborns due to zuclopenthixol.
Lactation: excretion of zuclopenthixol in breast milk is not known.
Pregnancy category:
Category A: Satisfactory and well-controlled studies show no risk to the fetus in the first or later trimester.
Category B: There is no evidence of risk to the fetus found in animal reproduction studies, and there are not enough studies on pregnant women.
Category C: Adverse effects on the fetus found with evidence in animal reproduction studies and no adequate evidence for an effect in humans, care must be taken for potential risks in pregnant women
Category D: There is adequate data available with sufficient evidence of human fetal risk from various platforms, but despite potential risks may be used only in emergency cases for potential benefits.
Category X: Drugs listed in this category outweigh risks over benefits. These category drugs should be prohibited for pregnant women.
Category N: There is no data available for the drug under this category.
Pharmacology:
zuclopenthixol is an antipsychotic medication that belongs to the class of drugs known as thioxanthenes. It blocks dopamine receptors in the brain, which regulate mood, behavior, and perception. By blocking these receptors, zuclopenthixol can help to decrease the symptoms of psychosis, such as hallucinations, delusions, and disordered thinking.
In addition to its effects on dopamine receptors, zuclopenthixol also has some affinity for other receptors in the brain, including serotonin and noradrenaline receptors. These actions may contribute to its efficacy in treating certain psychiatric and neurological conditions, such as bipolar disorder and Tourette’s syndrome.
Pharmacodynamics:
Mechanism of action: zuclopenthixol is an antipsychotic medication that works primarily by blocking dopamine receptors in the brain. Dopamine is a neurotransmitter involved in regulating mood, behavior, and perception, and abnormalities in dopamine signaling have been typically implicated in the development of psychotic disorders such as schizophrenia.
Pharmacokinetics:
Absorption
zuclopenthixol is readily absorbed from the gastrointestinal tract after oral administration. The absorption is relatively rapid, with peak plasma levels reached within 2 to 4 hours. The bioavailability of zuclopenthixol is approximately 60-70%, and food does not significantly affect its absorption.
Distribution
zuclopenthixol has a large volume of distribution, indicating that it is generally distributed throughout the body. The drug is highly protein-bound (greater than 99%), primarily to albumin. Zuclopenthixol crosses the blood-brain barrier and can exert its effects on the central nervous system.
Metabolism
zuclopenthixol is extensively metabolized in the liver via oxidation and conjugation. The primary metabolic pathway is oxidation by the cytochrome P450 system, particularly the CYP1A2 and CYP2D6 enzymes, which produce the major metabolite, 7-hydroxy-zuclopenthixol. This metabolite has similar pharmacological activity as the parent drug and contributes to its overall effects.
Elimination and Excretion
The elimination half-life of zuclopenthixol is approximately 30 hours, which is relatively long compared to other antipsychotic medications. The drug and drug metabolites are excreted in the urine, with only a tiny fraction in the feces.
Administration:
Oral administration
zuclopenthixol is available as an injection and as a tablet for oral administration. The dosing and administration of zuclopenthixol may vary depending on the indication and the patient’s needs.
When administering zuclopenthixol injection, healthcare professionals should follow proper techniques and ensure the injection is given into a large muscle mass, like the gluteal muscle. The injection should be given slowly, and the patient should be observed for nearly 30 minutes to monitor for adverse reactions.
zuclopenthixol tablets should be taken orally with or without food, as directed by the healthcare professional. The tablets should be generally swallowed whole with water and not crushed, chewed, or broken.
The zuclopenthixol dosage may need to be adjusted based on the patient’s response to treatment, age, weight, and other factors. It is essential to follow the healthcare professional’s instructions and to not change the dosage or stop taking the medication without consulting with the healthcare professional first.
Patients taking zuclopenthixol should be monitored for side effects, including sedation, weight gain, movement disorders, and changes in blood pressure and heart rate. Patients should also be generally monitored for signs, symptoms of an allergic reaction, like the difficulty breathing, and swelling of the lips, tongue/throat.
Overall, the administration of zuclopenthixol should be carefully monitored and managed by a healthcare professional with experience in the use of antipsychotic medications.
