With the use of antipsychotics (neuroleptics), the therapeutic effect develops over a period of a few days or weeks.During this period, it is necessary to carefully monitor the patient's condition.
Suicide attempts
Propensity to suicidal thoughts and attempts is characteristic for patients with psychosis, bipolar disorder and major depressive disorder, so drug therapy must be combined with careful medical supervision. Aripiprazole should be prescribed in a minimal amount sufficient to treat the patient, this will reduce the risk of overdose.
Admission of antidepressants, according to clinical studies, increases the risk of suicidal thoughts and attempts in young patients with depression and other mental disorders. In this regard, special care should be taken when using antidepressants, including as a combination therapy with antidepressants and aripiprazole for the treatment of young patients. Patients over the age of 24 did not show an increase in the incidence of suicidal ideation and behavior under the influence of antidepressants, and in patients older than 65 years there was a decrease in the incidence of this side effect.
Late dyskinesia
The risk of developing tardive dyskinesia increases with the duration of therapy with neuroleptics, so if you experience aripiprazole symptoms of late dyskinesia, you should reduce the dose of this drug or cancel it. After the withdrawal of therapy, these symptoms may temporarily increase or even appear for the first time.
Malignant neuroleptic syndrome (CNS)
In the treatment of neuroleptics, including aripiprazole. described a life-threatening symptom complex, known as malignant neuroleptic syndrome. This syndrome manifests itself as hyperpyrexia, muscle rigidity, mental disorders and instability of the autonomic nervous system (irregular heartbeats and blood pressure, tachycardia, sweating and arrhythmia). In addition, sometimes there is an increase in the activity of creatine phosphokinase in the blood plasma, myoglobinuria (rhabdomyolysis) and acute renal failure. In case of symptoms of NSA or unexplained fever, all antipsychotics, including aripiprazole. should be abolished.
Convulsions
Like other antipsychotics, aripiprazole should be used with caution in patients with a history of seizures or the risk of their development.
Psychoses associated with senile dementia and Alzheimer's disease
Based on the results of placebo-controlled studies in elderly patients (56-99 years old, mean age 82.4 years) with psychoses due to Alzheimer's disease, compared with the placebo group, there was an increased risk of death with aripiprazole therapy.
Mortality in the group of patients treated with aripiprazole. in comparison with the placebo group was 3.5% and 1.7%, respectively. Despite the fact that the causes of death were different, most of them were cardiovascular (eg, heart failure, sudden cardiac death) or infectious (eg, pneumonia).
Cerebrovascular side effects
In the same studies, cerebrovascular adverse reactions have been reported (eg, stroke, transient ischemic attack), including fatal outcomes in patients (78-88 years, mean age 84 years). Cerebrovascular side-effects were registered in patients treated with aripiprazole in 1.3% of cases compared with 0.6% of patients receiving placebo. This difference was not statistically significant. Nevertheless, in one of these studies with a fixed dose, there was a pronounced dose-dependent effect on the increased incidence of cerebrovascular adverse reactions in patients who received aripiprazole. Aripiprazole is not indicated for the treatment of psychosis against a background of dementia.
Hyperglycemia and diabetes mellitus
Hyperglycemia, in some cases expressed and accompanied by ketoacidosis or hyperosmolar coma with a fatal outcome, was noted in patients, who took atypical antipsychotics. Although the association between the administration of atypical antipsychotics and hyperglycemic-type disorders remains unclear, patients diagnosed with diabetes mellitus should regularly determine the blood glucose concentration when taking atypical antipsychotics. Patients who have risk factors for diabetes (obesity, history of diabetes in the family history), when taking atypical antipsychotics should determine the blood glucose concentration at the beginning of the course and periodically in the process of taking the drug. Patients taking atypical antipsychotics need constant monitoring of symptoms of hyperglycemia, including increased thirst, frequent urination, polyphagia, and weakness. Particular attention should be paid to patients with diabetes mellitus and risk factors for its development.
Weight gain
The increase in body weight is usually observed with schizophrenia and manic episodes in the background of bipolar disorder and the presence of concomitant diseases, the use of neuroleptics leads to weight gain, unhealthy lifestyles and can lead to serious complications. According to the post-marketing application of aripiprazole, there are reports of increased body weight, usually in patients with severe risk factors, such as history of diabetes, thyroid disease or pituitary adenoma. According to clinical studies, the use of aripiprazole does not result in clinically significant weight gain in adults.
Leukopenia, neutropenia, agranulocytosis
It is known that antipsychotics, including aripiprazole, can cause temporary changes in the blood picture - leukopenia, neutropenia, as well as agranulocytosis. Risk factors for development are a low number of white blood cells in a patient prior to treatment, as well as leukopenia and neutropenia caused by other drugs. It is necessary to regularly monitor the picture of blood in these patients, especially in the first months of treatment with aripiprazole.With a clinically significant decrease in the concentration of white blood cells of unclear etiology, consideration should be given to the abolition of the aripiprazole drug.
Patients with clinically significant neutropenia should be closely monitored for evidence of elevated body temperature or other signs of infection with a view to initiating appropriate treatment immediately. When severe neutropenia (neutrophil count less than 1000 / mm3) treatment with aripiprazole is interrupted until the blood picture is normalized.
Cardiovascular diseases
In connection with the risk of developing orthostatic hypotension aripiprazole should be used with caution in patients with cardiovascular diseases (myocardial infarction, ischemic heart disease, heart failure, cardiac conduction abnormalities in the history), cerebral circulation disorders or conditions predisposing to hypotension (dehydration, hypovolemia, hypotensive therapy).
Violation of the conduct (lengthening interval QT)
In clinical trials, the incidence of lengthening of the interval QT in patients with aripiprazole was comparable to the placebo group.Patients with congenital syndrome of an elongated interval QT Aripiprazole, like other antipsychotics, should be used with caution.
Cognitive and motor disorders
Like other antipsychotics, aripiprazole can cause cognitive and motor disorders. In particular, clinical studies of aripiprazole reported cases of drowsiness and retardation. During treatment, patients should refrain from driving and dangerous mechanisms.
Violation of thermoregulation
It is known that neuroleptics can cause a violation of thermoregulation. This should be taken into account when administering aripiprazole to patients who have an increased risk of overheating due to intense physical exertion, high ambient temperature, medications with m-holin-blocking activity, and dehydration.
Dysphagia
When using neuroleptics, cases of peristalsis of the esophagus and, as a consequence, aspiration pneumonia were noted.
Care should be taken when using in patients with risk factors for the development of aspiration pneumonia.
The risk of developing venous thromboembolism
The use of neuroleptics, including aripiprazole, may be associated with a risk of venous thromboembolism. In this regard, it is necessary to identify risk factors development of this complication before administration of aripiprazole, and during treatment with this drug. If necessary, measures should be taken to prevent the development of venous thromboembolism.
Pathological attraction to gambling
According to the post-marketing application of aripiprazole, cases of the development of pathological attraction to gambling have been noted, regardless of whether the patients previously played gambling. Patients with a history of gambling are at increased risk and should be carefully monitored.
Patients with Attention Deficit Hyperactivity Disorder (ADHD)
Despite the high incidence of concomitant pathologies of type I bipolar disorder and ADHD, data on the safety of simultaneous administration of aripiprazole and psycho-stimulating agents. Therefore, special care should be taken when using them simultaneously.
