Antipsychotic Drug
Antipsychotics, previously known as neuroleptics and major tranquilizers, are a class of psychotropic medication primarily used to manage psychosis (including delusions, hallucinations, paranoia or disordered thought), principally in schizophrenia but also in a range of other psychotic disorders. They are also the mainstay, together with mood stabilizers, in the treatment of bipolar disorder. Moreover, they are also used as adjuncts in the treatment of Treatment-resistant depression, treatment-resistant major depressive disorder. The use of antipsychotics may result in many unwanted side effects such as Extrapyramidal symptoms, involuntary movement disorders, gynecomastia, impotence, weight gain and metabolic syndrome. Long-term use can produce List of long term side effects of antipsychotics, adverse effects such as tardive dyskinesia, tardive dystonia, Akathisia, tardive akathisia, and brain tissue volume reduction. The long term use of antipsychotics often changes the bra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olanzapine
Olanzapine, sold under the brand name Zyprexa among others, is an atypical antipsychotic primarily used to treat schizophrenia and bipolar disorder. It is also sometimes used off-label for treatment of chemotherapy-induced nausea and vomiting and as an appetite stimulant. For schizophrenia, it can be used for both new-onset disease and long-term maintenance. It is taken by mouth or by injection into a muscle. Common side effects include significant weight gain, feeling tired, dizziness, constipation, dry mouth, and restlessness. Other side effects include low blood pressure with standing, allergic reactions, neuroleptic malignant syndrome, diabetes mellitus, seizures, and tardive dyskinesia. In older people with dementia, its use increases the risk of death. Use in the later part of pregnancy may result in a movement disorder in the baby for some time after birth. Although its mechanism of action is not entirely clear, it is known to block dopamine and serotonin re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Treatment-resistant Depression
Treatment-resistant depression (TRD) is often defined as major depressive disorder in which an affected person does not respond adequately to at least two different antidepressant medications at an adequate dose and for an adequate duration. Inadequate response has most commonly been defined as less than 25% reduction in depressive symptoms following treatment with an antidepressant. Many clinicians and researchers question the construct validity and clinical utility of treatment-resistant depression as currently conceptualized. There is ongoing debate as to whether inadequate response to other treatment modalities, such as psychotherapy, should be included in defining TRD. Treatment resistance is becoming more prominent with nearly 30% of individuals with major depressive disorder being termed treatment-resistant as defined above. There are many factors that may contribute to inadequate treatment, such as: a history of repeated or severe adverse childhood experiences, early d ...

Atypical Antipsychotic
The atypical antipsychotics (AAP), also known as second generation antipsychotics (SGAs) and serotonin–dopamine antagonists (SDAs), are a group of antipsychotic drugs (antipsychotic drugs in general are also known as tranquilizers and neuroleptics, although the latter is usually reserved for the '' typical antipsychotics'') largely introduced after the 1970s and used to treat psychiatric conditions. Some atypical antipsychotics have received regulatory approval (e.g. by the FDA of the US, the TGA of Australia, the MHRA of the UK) for schizophrenia, bipolar disorder, irritability in autism, and as an adjunct in major depressive disorder. Both generations of medication tend to block receptors in the brain's dopamine pathways. Atypicals are less likely than haloperidol—the most widely used typical antipsychotic—to cause extrapyramidal motor control disabilities in patients such as unsteady Parkinson's disease–type movements, body rigidity, and involuntary ...

Typical Antipsychotics
Typical antipsychotics (also known as major tranquilizers, and first generation antipsychotics) are a class of antipsychotic drugs first developed in the 1950s and used to treat psychosis (in particular, schizophrenia). Typical antipsychotics may also be used for the treatment of acute mania, agitation, and other conditions. The first typical antipsychotics to come into medical use were the phenothiazines, namely chlorpromazine which was discovered serendipitously. Another prominent grouping of antipsychotics are the butyrophenones, an example of which is haloperidol. The newer, second-generation antipsychotics, also known as atypical antipsychotics, have largely supplanted the use of typical antipsychotics as first-line agents due to the higher risk of movement disorders with typical antipsychotics. Both generations of medication tend to block receptors in the brain's dopamine pathways, but atypicals at the time of marketing were claimed to differ from typical antipsychoti ...

Haloperidol
Haloperidol, sold under the brand name Haldol among others, is a typical antipsychotic medication. Haloperidol is used in the treatment of schizophrenia, tics in Tourette syndrome, mania in bipolar disorder, delirium, agitation, acute psychosis, and hallucinations from alcohol withdrawal. It may be used by mouth or injection into a muscle or a vein. Haloperidol typically works within 30 to 60 minutes. A long-acting formulation may be used as an injection every four weeks for people with schizophrenia or related illnesses, who either forget or refuse to take the medication by mouth. Haloperidol may result in movement disorders such as tardive dyskinesia, and akathisia, both of which may be permanent. Neuroleptic malignant syndrome and QT interval prolongation may occur, the latter particularly with IV administration. In older people with psychosis due to dementia it results in an increased risk of death. When taken during pregnancy it may result in problems in the infant. I ...

Chlorpromazine
Chlorpromazine (CPZ), marketed under the brand names Thorazine and Largactil among others, is an antipsychotic medication. It is primarily used to treat psychotic disorders such as schizophrenia. Other uses include the treatment of bipolar disorder, severe behavioral problems in children including those with attention deficit hyperactivity disorder, nausea and vomiting, anxiety before surgery, and hiccups that do not improve following other measures. It can be given orally (by mouth), by intramuscular injection (injection into a muscle), or intravenously (injection into a vein). Chlorpromazine is in the typical antipsychotic class, and, chemically, is one of the phenothiazines. Its mechanism of action is not entirely clear but is believed to be related to its ability as a dopamine antagonist. It has antiserotonergic and antihistaminergic properties. Common side effects include movement problems, sleepiness, dry mouth, low blood pressure upon standing, and incr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Akathisia
Akathisia (IPA: /æ.kə.ˈθɪ.si.ə/) is a movement disorder characterized by a subjective feeling of inner restlessness accompanied by mental distress and/or an inability to sit still. Usually, the legs are most prominently affected. Those affected may fidget, rock back and forth, or pace, while some may just have an uneasy feeling in their body. The most severe cases may result in poor adherence to medications, exacerbation of psychiatric symptoms, and, because of this, aggression, violence, and/or suicidal thoughts. Akathisia is also associated with threatening behaviour and physical aggression in mentally disordered patients. However, the attempts to find potential links between akathisia and emerging suicidal or homicidal behaviour were not systematic and were mostly based on a limited number of case reports and small case series. Apart from these few low-quality studies, there is another more recent and better quality study (a systematic review from 2021) that concludes ...

Tardive Dystonia
Dystonia is a neurological hyperkinetic movement disorder in which sustained or repetitive muscle contractions occur involuntarily, resulting in twisting and repetitive movements or abnormal fixed postures. The movements may resemble a tremor. Dystonia is often intensified or exacerbated by physical activity, and symptoms may progress into adjacent muscles. The disorder may be hereditary or caused by other factors such as birth-related or other physical trauma, infection, poisoning (e.g., lead poisoning) or reaction to pharmaceutical drugs, particularly neuroleptics, or stress. Treatment must be highly customized to the needs of the individual and may include oral medications, chemodenervation botulinum neurotoxin injections, physical therapy, or other supportive therapies, and surgical procedures such as deep brain stimulation. Classification There are multiple types of dystonia, and many diseases and conditions may cause dystonia. Dystonia is classified by clinical char ...

Tardive Dyskinesia
Tardive dyskinesia (TD) is an iatrogenic disorder that results in involuntary repetitive body movements, which may include grimacing, sticking out the tongue or smacking the lips, which occurs following treatment with medication. Additional motor symptoms include chorea or athetosis. In about 20% of people with TD, the disorder interferes with daily functioning. If TD is present in the setting of a long-term drug therapy, reversibility can be determined primarily by severity of symptoms and how long symptoms have been present before the long-term drug has been stopped. Tardive dyskinesia occurs as a result of long-term use of dopamine-receptor-blocking medications such as antipsychotics and metoclopramide. These medications are usually used for mental illness but may also be given for gastrointestinal or neurological problems. The condition typically develops only after months to years of use. The diagnosis is based on the symptoms after ruling out other potential causes. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Long Term Side Effects Of Antipsychotics
This is a general list of long-term side effects associated with Antipsychotic (neuroleptic) medication. Many patients will not develop these side effects, although there is still a significant possibility of risks associated with Antipsychotic usage. The percentage of patients affected by side effects like Tardive dyskinesia is significantly high and estimated to be a 20-50% prevalence. These side effects are serious and some of them are permanent, and many remain a crucial concern for companies and healthcare professionals and substantial efforts are being encouraged to reduce the potential risks for future antipsychotics through more clinical trials and drug development. Much is still being discovered about long term side- effects and insufficient research has been done to verify the mechanistic causes and severity of these long term side-effects Overprescription of antipsychotics among seniors with dementia is evident in spite of side effects.

Metabolic Syndrome
Metabolic syndrome is a clustering of at least three of the following five medical conditions: abdominal obesity, high blood pressure, high blood sugar, high serum triglycerides, and low serum high-density lipoprotein (HDL). Metabolic syndrome is associated with the risk of developing cardiovascular disease and type 2 diabetes. In the U.S., about 25% of the adult population has metabolic syndrome, a proportion increasing with age, particularly among racial and ethnic minorities. Insulin resistance, metabolic syndrome, and prediabetes are closely related to one another and have overlapping aspects. The syndrome is thought to be caused by an underlying disorder of energy utilization and storage, but the cause of the syndrome is an area of ongoing medical research. Researchers debate whether a diagnosis of metabolic syndrome implies differential treatment or increases risk of cardiovascular disease beyond what is suggested by the sum of its individual components. Signs and s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weight Gain
Weight gain is an increase in body weight. This can involve an increase in muscle mass, fat deposits, excess fluids such as water or other factors. Weight gain can be a symptom of a serious medical condition. Description Weight gain occurs when more energy (as calories from food and beverage consumption) is gained than the energy expended by life activities, including normal physiological processes and physical exercise. If enough weight is gained due to increased body fat deposits, one may become overweight or obese, generally defined as having more body fat (adipose tissue) than is considered good for health. The Body Mass Index (BMI) measures body weight in proportion to height and defines optimal, insufficient, and excessive weight based on the ratio. Having excess adipose tissue (fat) is a common condition, especially where food supplies are plentiful and lifestyles are sedentary. Being overweight or having obesity may increase the risk of several diseases, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
