The oral capsule of cariprazine is taken usually once a day with or without food. It should be strictly taken according to the prescription. The dose should not be increased or decreased without consulting a healthcare provider. Skipping doses may reduce the effectiveness of the treatment. Thus, patients should try to take the medication at the same time each day so that they can develop a routine.

Cariprazine should not be chewed or broken. If a dose is missed, it should be taken as soon as possible unless it is almost time for the next dose. In that case, the missed dose should be skipped to avoid doubling up.

Cariprazine acts by modulating the activity of certain neurotransmitters in the brain, particularly dopamine and serotonin. These neurotransmitters have been involved in mood regulation, perception, and cognition, and disturbances in their balance lead to psychiatric disorders such as schizophrenia and bipolar disorder.

Dopamine Receptor Binding: Cariprazine has high affinity to dopamine D2 and D3 receptors. The drug has partial agonism at those receptors; thus, the drug is both a receptor stimulant and blocker as it depends on the dopamine concentration in the brain. The property makes it useful for stabilizing the activity of dopamine, thus reducing psychotic symptoms or mood swings.

Cariprazine also acts on serotonin receptors, such as 5-HT1A and 5-HT2A, which are involved in mood regulation and anxiety. Cariprazine balances mood by interacting with these receptors and reducing symptoms like anxiety and agitation.

This can lead to a higher risk of side effects such as movement disorders for example, tremors or rigidity. The cariprazine action alone helps reduce these risks, therefore making it a more favored option for long-term use.

As with all medicines, Cariprazine is likely to cause some side effects. Some of these include the following:

• Akathisia (a restlessness or inability to stay seated)
• Insomnia
• Dizziness
• Weight gain
• Sedation/drowsiness
• Gastrointestinal complaints such as nausea or constipation

The more rare but serious adverse effects include:

Extrapyramidal Symptoms (EPS): These include motor symptoms like tremors, muscle rigidity, and bradykinesia.

Neuroleptic Malignant Syndrome (NMS): A rare but very dangerous condition that is indicated by high fever, muscle rigidity, altered mental status, and autonomic dysregulation.

Metabolic Changes: These can be increased blood sugar, cholesterol, and triglycerides.

Tardive Dyskinesia: This is a potentially irreversible condition characterized by involuntary movements, especially of the face and mouth.

Patients should inform their healthcare provider immediately in case of any unusual or severe side effects.

Risk of Suicide: Like all antipsychotics, Cariprazine carries a boxed warning for the risk of suicidality, especially with younger patients. Patients treated with Cariprazine should be monitored closely in the treatment process, most especially when beginning treatment with the drug or when it is titrated.

Elderly Patients with Dementia-Related Psychosis: Cariprazine is not approved for the treatment of dementia-related psychosis because of an increased risk of death and stroke in elderly patients.

Cardiovascular Issues: Patients with a history of heart disease should be handled with caution because Cariprazine can lead to QT prolongation, which is a condition related to the heart’s electrical activity.

Liver and Kidney Function: Patients with liver or kidney problems may require dose adjustments or closer monitoring during treatment.

Cariprazine can interact with other drugs, so a patient should always report all drugs that he is currently taking to his doctor. The most common drug interactions are:

CYP450 Enzyme Modulators: The metabolism of Cariprazine in the liver involves the CYP3A4 enzyme. Drugs that inhibit or induce this enzyme may alter the concentration of Cariprazine in the body. For instance, ketoconazole, a CYP3A4 inhibitor, may increase the levels of Cariprazine while carbamazepine, a CYP3A4 inducer, will decrease its effectiveness.

Other CNS Depressants: Concomitant use of Cariprazine with other central nervous system depressants (e.g., alcohol, benzodiazepines) may increase the risk of drowsiness, sedation, or respiratory depression.

Antihypertensive Drugs: Cariprazine may reduce blood pressure. Combination with antihypertensive drugs may augment the effect of lowering the blood pressure.

The appropriate dosage of Cariprazine will depend on the individual’s condition and response to the medication. Generally:

Schizophrenia: 1.5 mg per day initially, titrating up to 6 mg per day based on response.

Bipolar Disorder: 3 mg per day initially, titrating up to 6 mg per day.

It is necessary to observe a dosing schedule and avoid doses higher than those recommended.

The drug, Cariprazine is only prescribed when a health care professional assesses the patient for its usage before treatment. It is therefore prescribed by a health care professional. There should be close follow up to review whether the progress and adverse effect are changing or not.

General Information

1. What is Cariprazine used for?

   • Cariprazine is primarily used to treat schizophrenia and bipolar disorder, particularly for managing manic and mixed episodes.

2. How does Cariprazine work?

   • Cariprazine works as a dopamine D2 and D3 receptor partial agonist. It helps to balance dopamine levels in the brain, which can alleviate symptoms of psychosis and mood disorders.

3. Is Cariprazine effective for depression?

   • Cariprazine is not approved specifically for depression but may be effective in treating depressive episodes associated with bipolar disorder. It is sometimes used off-label in other contexts.

Dosage and Administration

4. What is the typical starting dosage of Cariprazine?

   • The usual starting dose is 1.5 mg once daily, which may be adjusted based on the patient’s response and tolerability.

5. How should Cariprazine be taken?

   • Cariprazine is taken orally, with or without food. It is available in capsule form and should be swallowed whole.

6. What should I do if I miss a dose of Cariprazine?

   • If you miss a dose, take it as soon as you remember. If it is close to the time for your next dose, skip the missed dose and resume your regular schedule. Do not double the dose.

Side Effects

7. What are the common side effects of Cariprazine?

   • Common side effects may include insomnia, akathisia (restlessness), and gastrointestinal issues like nausea or vomiting.

8. Are there any serious side effects associated with Cariprazine?

   • Serious side effects can include tardive dyskinesia, metabolic changes (such as weight gain and diabetes), and increased risk of stroke in elderly patients with dementia-related psychosis.

9. Can Cariprazine cause weight gain?

   • Weight gain is a potential side effect. Regular monitoring of weight, diet, and lifestyle is recommended.

Drug Interactions

10. Can I take Cariprazine with other medications?
