Clopixol Depot Im Injection Solution

Description

Composition

Clopixol Depot contains the following components:

• Active Ingredient: Zuclopenthixol decanoate (200 mg/ml)
• Other Ingredients: Medium chain triglycerides

Indications

Clopixol Depot is indicated for the maintenance treatment of schizophrenia and other psychoses, including:

• Agitation
• Psychomotor disturbances
• Hostility
• Suspiciousness
• Aggression
• Affective reactions

Mechanism of Action

Dopamine Receptor Antagonism

Clopixol Depot functions as a typical antipsychotic by blocking dopamine receptors, specifically D1 and D2 receptors. This action helps reduce the overactivity of dopamine in the brain, which is thought to contribute to symptoms of schizophrenia and psychoses.

Other Receptor Interactions

In addition to dopamine receptors, Clopixol Depot has a high affinity for:

• Alpha-1 adrenergic receptors: Blocking these receptors can help reduce symptoms such as agitation and aggression.
• 5-HT2 receptors: These serotonin receptors, when antagonized, can improve mood and reduce anxiety.

Long-Acting Formulation

The esterification of zuclopenthixol with decanoic acid makes Clopixol Depot highly lipophilic. When injected intramuscularly, it diffuses slowly into surrounding tissues and gradually converts into the active component, zuclopenthixol. This slow release ensures a consistent therapeutic effect over 2 to 4 weeks.

Pharmacokinetics and Metabolism

Absorption

Administered intramuscularly, Clopixol Depot is designed for slow absorption, providing sustained release of zuclopenthixol.

Distribution

Zuclopenthixol is widely distributed throughout the body, crossing the blood-brain barrier to exert its therapeutic effects and entering breast milk.

Metabolism

Zuclopenthixol is primarily metabolized in the liver through:

• Sulfoxidation
• Side chain N-dealkylation
• Glucuronic acid conjugation

The metabolites are pharmacologically inactive.

Excretion

Most of zuclopenthixol is metabolized, with minimal amounts excreted unchanged in the urine. The metabolites are also excreted via urine.

Dosage and Administration

Clopixol Depot is administered as an intramuscular injection by a healthcare professional. The dosage and frequency depend on the patient’s condition and response to treatment. Typically, it is given every 2 to 4 weeks.

Contraindications

Clopixol Depot should not be used in the following cases:

• Hypersensitivity to zuclopenthixol or other ingredients
• Acute alcohol, barbiturate, and opiate poisoning
• Severe liver disease
• Pregnancy (unless absolutely necessary)
