Interactions between Brexpiprazole and Vigabatrin

Brexpiprazole has a moderate potential interaction with Alcoholism.

Antipsychotic and neuroleptic drugs can lower the seizure threshold and trigger seizures in a dose-dependent manner. This risk is greatest in patients with a history of seizures or with conditions that lower the seizure threshold. Therapy with these drugs should be administered cautiously in patients with a history of seizures or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism.

Brexpiprazole has a moderate potential interaction with Arrhythmia.

The use of atypical antipsychotic agents has been associated with orthostatic hypotension and syncope. Therapy with atypical antipsychotics should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with atypical antipsychotics. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

Brexpiprazole has a major potential interaction with Bipolar Disorder.

Antidepressants increased the risk of suicidal thoughts and behavior in children, adolescents, and young adults in short-term trials; these trials did not show increased risk in patients older than 24 years and risk was reduced in patients 65 years and older. Adult and pediatric patients with major depressive disorder may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressants; this risk may persist until significant remission occurs. Suicide is a known risk of depression and certain other psychiatric disorders; such disorders are the strongest predictors of suicide. Patients of all ages treated with antidepressants for any indication should be monitored appropriately and observed closely for clinical worsening, suicidality, and unusual changes in behavior, especially during the first few months of drug therapy, and at times of dose changes. Family members/caregivers should be advised to monitor for changes in behavior and to notify the health care provider. Changing the therapeutic regimen (including discontinuing the medication) should be considered in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts or behaviors.

Brexpiprazole has a moderate potential interaction with Breast Cancer.

The chronic use of neuroleptic agents can cause persistent elevations in prolactin levels due to antagonism of dopamine D2 receptors. Based on in vitro data, approximately one-third of human breast cancers are thought to be prolactin-dependent. The clinical significance of this observation with respect to long-term neuroleptic therapy is unknown. Chronic administration of neuroleptic drugs has been associated with mammary tumorigenesis in rodent studies but not in human clinical or epidemiologic studies. Until further data are available, therapy with neuroleptic agents should be administered cautiously in patients with a previously detected breast cancer. Caution is also advised in patients with preexisting hyperprolactinemia. Hyperprolactinemia may suppress hypothalamic gonadotrophin releasing hormone (GnRH), resulting in reduced pituitary gonadotropin secretion. This, in turn, may inhibit reproductive function by impairing gonadal steroidogenesis in both female and male patients. Galactorrhea, amenorrhea, gynecomastia, and impotence have been reported in patients receiving prolactin-elevating compounds; however, the clinical significance of elevated serum prolactin levels is unknown for most patients. Long-standing hyperprolactinemia when associated with hypogonadism may lead to decreased bone density in both female and male patients.

Vigabatrin has a moderate potential interaction with Central Nervous System Disorders.

Vigabatrin has produced pathological changes in the brains of rats and long-term neurobehavioral abnormalities (convulsions, neuromotor impairment, learning deficits) were also observed. In humans, abnormal MRI signal changes characterized by increased T2 signal and restricted diffusion in a symmetric pattern involving the thalamus, basal ganglia, brain stem, and cerebellum have been observed in some infants treated for infantile spasms (IS) with vigabatrin. Studies of the effects of vigabatrin on MRI and changes in visual and somatosensory evoked potentials (EP) in adult epilepsy patients have not been clearly defined.

Brexpiprazole has a moderate potential interaction with Cerebrovascular Insufficiency.

The use of atypical antipsychotic agents has been associated with orthostatic hypotension and syncope. Therapy with atypical antipsychotics should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with atypical antipsychotics. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

Brexpiprazole has a moderate potential interaction with Dehydration.

The use of atypical antipsychotic agents has been associated with orthostatic hypotension and syncope. Therapy with atypical antipsychotics should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with atypical antipsychotics. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

Brexpiprazole has a major potential interaction with Dementia.

Antipsychotic drugs are not approved for the treatment of patients with dementia-related psychosis. Older patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death; although the causes were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. A causal relationship with antipsychotic use has not been established. In controlled trials in older patients with dementia-related psychosis, patients randomized to risperidone, aripiprazole, and olanzapine had higher incidence of cerebrovascular adverse events (e.g., stroke, transient ischemic attack), including fatalities, compared to patients treated with placebo.

Brexpiprazole has a major potential interaction with Depression.

Antidepressants increased the risk of suicidal thoughts and behavior in children, adolescents, and young adults in short-term trials; these trials did not show increased risk in patients older than 24 years and risk was reduced in patients 65 years and older. Adult and pediatric patients with major depressive disorder may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressants; this risk may persist until significant remission occurs. Suicide is a known risk of depression and certain other psychiatric disorders; such disorders are the strongest predictors of suicide. Patients of all ages treated with antidepressants for any indication should be monitored appropriately and observed closely for clinical worsening, suicidality, and unusual changes in behavior, especially during the first few months of drug therapy, and at times of dose changes. Family members/caregivers should be advised to monitor for changes in behavior and to notify the health care provider. Changing the therapeutic regimen (including discontinuing the medication) should be considered in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts or behaviors.

Vigabatrin has a moderate potential interaction with Depression.

Antiepileptic drugs (AEDs) have been associated with an increased risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Pooled analyses of 199 placebo-controlled clinical studies involving the use of 11 different AEDs showed that patients receiving AEDs had approximately twice the risk of suicidal thinking or behavior compared to patients receiving placebo. AEDs should be administered cautiously in patients with depression or other psychiatric disorders; phentermine-topiramate should be avoided in patients with history of suicidal attempts or active suicidal ideation. The risk of suicidal thoughts and behavior should be carefully assessed against the risk of untreated illness, bearing in mind that epilepsy and many other conditions for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Patients, caregivers, and families should be alert to the emergence or worsening of signs and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts or behavior. If patients have symptoms of suicidal ideation or behavior, a dosage reduction or treatment discontinuation should be considered.

Brexpiprazole has a moderate potential interaction with Diabetes Mellitus.

Hyperglycemia, in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, has been reported with the use of atypical antipsychotic agents. Patients with diabetes should be monitored for worsening control of blood glucose when treated with these agents. It is recommended that patients with risk factors for diabetes mellitus starting treatment with atypical antipsychotics should undergo fasting blood glucose testing at the beginning of treatment, and periodically thereafter. Any patient treated with atypical antipsychotics should be monitored for symptoms of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness. Patients who develop symptoms of hyperglycemia during treatment with atypical antipsychotics should undergo fasting blood glucose testing. In some cases, hyperglycemia has resolved when treatment with these agents was discontinued; however, some patients required continuation of anti-diabetic treatment despite discontinuation of the atypical antipsychotic drug.

Brexpiprazole has a moderate potential interaction with Diarrhea.

The use of atypical antipsychotic agents has been associated with orthostatic hypotension and syncope. Therapy with atypical antipsychotics should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with atypical antipsychotics. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

Brexpiprazole has a moderate potential interaction with Dysphagia.

Esophageal dysmotility and aspiration have been associated with the use of antipsychotic drugs. These drugs should be administered cautiously in patients at risk for aspiration pneumonia.

Brexpiprazole has a moderate potential interaction with Head Injury.

Antipsychotic and neuroleptic drugs can lower the seizure threshold and trigger seizures in a dose-dependent manner. This risk is greatest in patients with a history of seizures or with conditions that lower the seizure threshold. Therapy with these drugs should be administered cautiously in patients with a history of seizures or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism.

Brexpiprazole has a moderate potential interaction with Heart Failure.

The use of atypical antipsychotic agents has been associated with orthostatic hypotension and syncope. Therapy with atypical antipsychotics should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with atypical antipsychotics. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

Brexpiprazole has a moderate potential interaction with High Cholesterol.

Atypical antipsychotic drugs have been associated with undesirable alterations in lipid levels. While all agents in the class have been shown to produce some changes, each drug has its own specific risk profile. Before or soon after initiation of antipsychotic medications, a fasting lipid profile should be obtained at baseline and monitored periodically during treatment.

Brexpiprazole has a moderate potential interaction with History - Myocardial Infarction.

The use of atypical antipsychotic agents has been associated with orthostatic hypotension and syncope. Therapy with atypical antipsychotics should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with atypical antipsychotics. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

Brexpiprazole has a moderate potential interaction with Hyperprolactinemia.

The chronic use of neuroleptic agents can cause persistent elevations in prolactin levels due to antagonism of dopamine D2 receptors. Based on in vitro data, approximately one-third of human breast cancers are thought to be prolactin-dependent. The clinical significance of this observation with respect to long-term neuroleptic therapy is unknown. Chronic administration of neuroleptic drugs has been associated with mammary tumorigenesis in rodent studies but not in human clinical or epidemiologic studies. Until further data are available, therapy with neuroleptic agents should be administered cautiously in patients with a previously detected breast cancer. Caution is also advised in patients with preexisting hyperprolactinemia. Hyperprolactinemia may suppress hypothalamic gonadotrophin releasing hormone (GnRH), resulting in reduced pituitary gonadotropin secretion. This, in turn, may inhibit reproductive function by impairing gonadal steroidogenesis in both female and male patients. Galactorrhea, amenorrhea, gynecomastia, and impotence have been reported in patients receiving prolactin-elevating compounds; however, the clinical significance of elevated serum prolactin levels is unknown for most patients. Long-standing hyperprolactinemia when associated with hypogonadism may lead to decreased bone density in both female and male patients.

Brexpiprazole has a moderate potential interaction with Hypotension.

The use of atypical antipsychotic agents has been associated with orthostatic hypotension and syncope. Therapy with atypical antipsychotics should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with atypical antipsychotics. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

Brexpiprazole has a moderate potential interaction with Ischemic Heart Disease.

The use of atypical antipsychotic agents has been associated with orthostatic hypotension and syncope. Therapy with atypical antipsychotics should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with atypical antipsychotics. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

Brexpiprazole has a moderate potential interaction with Liver Disease.

Brexpiprazole is primarily metabolized by the liver. It is recommended to reduce the dose of brexpiprazole in patients with moderate to severe hepatic impairment (Child-Pugh score greater than or equal to 7) as these patients might have a higher exposure to brexpiprazole than patients with normal hepatic function.

Brexpiprazole has a major potential interaction with Neuroleptic Malignant Syndrome.

The central dopaminergic blocking effects of neuroleptic agents may precipitate or aggravate a potentially fatal symptom complex known as neuroleptic malignant syndrome (NMS). NMS is observed most frequently when high-potency agents like haloperidol are administered intramuscularly, but may occur with any neuroleptic agent given for any length of time. Clinical manifestations of NMS include hyperpyrexia, muscle rigidity, altered mental status and autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis and cardiac arrhythmias). Additional signs may include elevated creatine phosphokinase, myoglobinuria, and acute renal failure. Neuroleptic agents should not be given to patients with active NMS and should be immediately discontinued if currently being administered in such patients. In patients with a history of NMS, introduction or reintroduction of neuroleptic agents should be carefully considered, since NMS may recur.

Brexpiprazole has a moderate potential interaction with Neutropenia.

Cases of leukopenia, neutropenia, and agranulocytosis have been reported with the use of atypical antipsychotic agents. Patients with preexisting low white blood cell count may be at increased risk. Therapy with these agents should be administered cautiously in patients with a history of, or predisposition to, decreased white blood cell or neutrophil counts. Clinical monitoring of hematopoietic function is recommended. At the first sign of a clinically significant decline in white blood cells, discontinuation of atypical antipsychotic therapy should be considered in the absence of other causative factors, and the patient closely monitored for fever or other signs and symptoms of infection.

Vigabatrin has a moderate potential interaction with Peripheral Neuropathy.

Vigabatrin causes symptoms of peripheral neuropathy in adults. There is insufficient evidence to determine if development of these signs and symptoms were related to duration of vigabatrin treatment, cumulative dose, or if the findings of peripheral neuropathy were completely reversible upon discontinuation of vigabatrin. Therapy with vigabatrin should be administered cautiously in patients with peripheral neuropathy.

Vigabatrin has a moderate potential interaction with Psychosis.

Antiepileptic drugs (AEDs) have been associated with an increased risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Pooled analyses of 199 placebo-controlled clinical studies involving the use of 11 different AEDs showed that patients receiving AEDs had approximately twice the risk of suicidal thinking or behavior compared to patients receiving placebo. AEDs should be administered cautiously in patients with depression or other psychiatric disorders; phentermine-topiramate should be avoided in patients with history of suicidal attempts or active suicidal ideation. The risk of suicidal thoughts and behavior should be carefully assessed against the risk of untreated illness, bearing in mind that epilepsy and many other conditions for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Patients, caregivers, and families should be alert to the emergence or worsening of signs and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts or behavior. If patients have symptoms of suicidal ideation or behavior, a dosage reduction or treatment discontinuation should be considered.

Brexpiprazole has a moderate potential interaction with Renal Dysfunction.

Therapy with some atypical antipsychotic agents should be administered cautiously in patients with renal impairment and the dosage should be reduced accordingly. These agents are not recommended in patients with severe renal impairment.

Brexpiprazole has a moderate potential interaction with Seizures.

Antipsychotic and neuroleptic drugs can lower the seizure threshold and trigger seizures in a dose-dependent manner. This risk is greatest in patients with a history of seizures or with conditions that lower the seizure threshold. Therapy with these drugs should be administered cautiously in patients with a history of seizures or other predisposing factors, such as head trauma, CNS abnormalities, and alcoholism.

Brexpiprazole has a moderate potential interaction with Syncope.

The use of atypical antipsychotic agents has been associated with orthostatic hypotension and syncope. Therapy with atypical antipsychotics should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with atypical antipsychotics. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

Brexpiprazole has a moderate potential interaction with Tardive Dyskinesia.

Tardive dyskinesia (TD) has occurred in patients treated with antipsychotic drugs; the syndrome consists of potentially irreversible, involuntary, dyskinetic movements. The risk appears highest in older patients (particularly older women) but it is not possible to predict which patients are likely to develop TD; whether antipsychotic drugs differ in their potential to cause TD is unknown. The risk of TD and the likelihood that it will become irreversible increase with the duration of therapy and the total cumulative dose. The syndrome can develop after relatively brief treatment periods, even at low dosages; it may also occur after discontinuation of therapy. TD may remit (partially or completely) upon discontinuation of antipsychotic therapy, although antipsychotic therapy itself may suppress (or partially suppress) signs/symptoms of TD, possibly masking the underlying process; the effect of symptomatic suppression on the long-term course of TD is unknown. In patients with preexisting drug-induced TD, initiating or increasing the dosage of antipsychotic therapy may temporarily mask the symptoms of TD but could eventually worsen the condition. In patients requiring chronic therapy, the lowest dose and shortest duration of therapy producing a satisfactory clinical response are recommended; the need for continued therapy should be reassessed periodically. If signs/symptoms of TD occur during antipsychotic therapy, discontinuation of the offending agent should be considered; however, some patients may require treatment despite the presence of TD.

Vigabatrin has a major potential interaction with Visual Defect/Disturbance.

Vigabatrin causes permanent bilateral concentric visual field constriction. The onset of vision loss from vigabatrin is unpredictable, and can occur within weeks of starting treatment or sooner, or at any time after starting treatment, even after months or years. The risk of vision loss increases with increasing dose and cumulative exposure, but there is no dose or exposure known to be free of risk of vision loss. Because of the risk of vision loss, and because, when it is effective, vigabatrin provides an observable symptomatic benefit, patient response and continued need for treatment should be periodically assessed. If the need clearly outweighs the risk, caution should be exercised when using vigabatrin therapy in patients with, or at high risk of, other types of irreversible vision loss. Vigabatrin should not be used in patients that are being treated for retinopathy or glaucoma.

Brexpiprazole has a moderate potential interaction with Vomiting.

The use of atypical antipsychotic agents has been associated with orthostatic hypotension and syncope. Therapy with atypical antipsychotics should be administered cautiously in patients with hypotension or conditions that could be exacerbated by hypotension, such as a history of myocardial infarction, angina, or ischemic stroke. Patients with dehydration (e.g., due to severe diarrhea or vomiting) may be predisposed to hypotension and should also be managed carefully during therapy with atypical antipsychotics. Blood pressure should be monitored at regular intervals, particularly during dosage escalation or whenever dosage has been altered, and patients should be advised not to rise abruptly from a sitting or recumbent position.

Brexpiprazole has a moderate potential interaction with Weight Loss.

Weight gain has been observed with atypical antipsychotic use. While all agents in the class have been shown to produce some changes, each drug has its own specific risk profile. When treating pediatric patients with atypical antipsychotic agents, weight gain should be monitored and assessed against that expected for normal growth. Monitor weight at baseline and frequently thereafter.

Brexpiprazole has a moderate potential interaction with Weight Loss.

Hyperglycemia, in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, has been reported with the use of atypical antipsychotic agents. Patients with diabetes should be monitored for worsening control of blood glucose when treated with these agents. It is recommended that patients with risk factors for diabetes mellitus starting treatment with atypical antipsychotics should undergo fasting blood glucose testing at the beginning of treatment, and periodically thereafter. Any patient treated with atypical antipsychotics should be monitored for symptoms of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness. Patients who develop symptoms of hyperglycemia during treatment with atypical antipsychotics should undergo fasting blood glucose testing. In some cases, hyperglycemia has resolved when treatment with these agents was discontinued; however, some patients required continuation of anti-diabetic treatment despite discontinuation of the atypical antipsychotic drug.
