Malignant neuroleptic syndrome
Malignant neuroleptic syndrome is characterized by pallor, hyperthermia, muscle rigidity, dysfunction of the autonomic nervous system, impaired consciousness. Signs of autonomic nervous system dysfunction, such as increased sweating, lability of blood pressure and pulse may precede the onset of hyperthermia and, therefore, be early warning signs.In the case of an unexplained increase in body temperature, treatment with sulpiride should be stopped. The genesis of the development of the ZNS remains unclear: it is assumed that its mechanism is played by the blockade of dopamine receptors in the striatum and hypothalamus, and congenital predisposition (idiosyncrasy) is not ruled out. The development of the syndrome can contribute to intercurrent infection, dehydration or organic brain damage.
QT interval extension
Sulpiride can cause a dose-dependent lengthening of the QT interval. This effect increases the risk of developing severe ventricular arrhythmias, such as ventricular pirouette torsades de pointes.
Before starting therapy with neuroleptics, you need to make sure that there are no risk factors predisposing to the development of severe cardiac arrhythmias, such as: a bradycardia with a heart rate of less than 55 beats per minute; slowing of intracardiac conduction, congenital prolongation of the QT interval, or prolongation of the QT interval associated with simultaneous use of other drugs extending the QT interval; violation of electrolyte metabolism: hypomagnesemia, and especially,hypokalemia - should be adjusted; In addition, such patients need to ensure a constant monitoring of the electrolyte content in the blood, ECG monitoring and constant medical supervision. Patients with the above risk factors for the need for sulpiride should be used with caution (see the sections "With caution", "Side effect").
Extrapyramidal syndrome
In extrapyramidal syndrome caused by neuroleptics, m-cholinoblocking drugs should be prescribed, and not dopaminergic agonists (see section "Interaction with other drugs").
Stroke
In randomized clinical trials comparing the effects of some atypical antipsychotics with placebo in elderly patients with dementia, there was a triple increase in the risk of developing cerebrovascular events. The mechanism of this risk is not known. It can not be ruled out that this risk increases with other neuroleptics or in other patient populations, so
sulpiride should be used with caution in patients with risk factors for stroke.
Older patients with dementia
In elderly patients with psychosis associated with dementia, in the treatment with antipsychotic drugs, there was an increase (1.6-1.7 times) in the risk of death, in most cases associated with cardiovascular (heart failure, sudden death) or infectious diseases (pneumonia ). An analysis of 17 placebo-controlled studies showed that the risk of death in elderly patients with dementia who received atypical antipsychotics is 4.5%, and 2.6% with placebo. Comparative studies have confirmed that treatment with both atypical and typical antipsychotics can increase mortality. The extent to which an increase in mortality may be due to an antipsychotic drug, rather than to certain features of patients, is not clear.
Venous thromboembolic complications
When using antipsychotic drugs, there have been cases of venous thromboembolic complications, including pulmonary embolism, sometimes fatal; deep vein thrombosis. Therefore, all possible risk factors for venous thromboembolic complications must be identified beforebeginning and during drug therapy; it is also necessary to take appropriate preventive measures (see the section "With caution").
Patients with epilepsy
Due to the fact that antipsychotics can lower the epileptogenic threshold, in the appointment of sulpiride, patients with epilepsy should be provided with strict medical supervision.
Patients with Parkinson's disease receiving dopaminergic agonists
In exceptional cases,
sulpiride should not be prescribed to patients suffering from Parkinson's disease. If there is an urgent need for treatment with neuroleptics in patients with Parkinson's disease receiving dopaminergic agonists, a gradual reduction in the doses of the latter should be undertaken until complete withdrawal. Abrupt withdrawal of dopaminergic drugs may increase the risk of developing a patient's CNS (see sections "With caution", "Interaction with other drugs").
Leukopenia, neutropenia, agranulocytosis
With prolonged use of antipsychotics, it is recommended to regularly monitor the composition of peripheral blood, especially if a fever occurs or an infection of an unexplained etiology is established (the possibility of developing leukopenia and agranulocytosis).In case of significant hematological changes in the peripheral blood, treatment with sulfirid should be stopped.
Patients with impaired renal function
In patients with impaired renal function, reduced doses of sulpiride should be used (see section "Method of administration and dose").
Patients with diabetes mellitus or with risk factors for the development of diabetes mellitus.
Since there is information about the development of hyperglycemia in patients taking atypical antipsychotics, patients with an established diagnosis of diabetes mellitus or risk factors for its development who are prescribed sulfide therapy should monitor blood sugar levels.
The use of alcohol or the use of medications containing alcohol, during treatment with sulpiride is strictly prohibited.
It should be borne in mind that
sulpiride when used simultaneously with general stimulating substances (eg anorectics, some anti-asthmatic drugs), can cause anxiety, neurosis, excitability and insomnia.
Special precautions should be observed when prescribing sulpiride to young women with unsteady menstrual cycles.
It is recommended to conduct constant medical supervision of the condition of newborns who underwent intrauterine exposure to sulpiride. In newborns, there is a risk of developing unwanted reactions involving extrapyramidal symptoms and / or withdrawal symptoms.
Attention Deficit Hyperactivity Disorder (or without it)
It should be taken into account that in connection with the influence of sulpiride on cognitive processes in children, it is necessary to monitor the child's ability to learn annually. It is necessary to regularly adjust the dose of the drug taking into account the clinical state of the child.
