The newest therapy is the transoral incisionless fundoplication (TIF). This is an incisionless fundoplication performed with an endoscope that is inserted through the mouth and into the stomach.
Are atypical antipsychotics first-line treatment?
Consequently, atypical antipsychotics are now considered to be the first-line treatment for schizophrenia, with the exception of clozapine, which is considered a second-line agent because of risks associated with its use. This review will discuss the literature on atypical antipsychotic efficacy in psychotic disorders.
What are first-generation antipsychotics used for?
First-generation 'typical' antipsychotics are an older class of antipsychotic than second-generation 'atypical' antipsychotics. First-generation antipsychotics are used primarily to treat positive symptoms such as hallucinations and delusions.
What is considered to be the first-line of treatment for schizophrenia?
Antipsychotic medications are the first-line medication treatment for schizophrenia. They have been shown in clinical trials to be effective in treating symptoms and behaviors associated with the disorder. However, antipsychotic medications have significant side effects.
Which of the following drug classification is used to treat GERD or gastric ulcers?
H2 antagonists are used to treat acute gastric and duodenal ulcers and gastroesophageal disease, as well as for maintenance to prevent ulcer recurrence. Proton pump inhibitors are used to treat hyperacidity conditions (e.g., GERD, Zollinger-Ellison syndrome) and peptic and gastric ulcer disease.
What is the strongest GERD medication?
PPIs are the most powerful medications available for treating GERD. These agents should be used only when this condition has been objectively documented. They have few adverse effects. However, data have shown that PPIs can interfere with calcium homeostasis and aggravate cardiac conduction defects.
What drug classification is acid reflux?
Proton pump inhibitors (PPIs) In contrast, prescription PPIs are used to treat conditions like gastroesophageal reflux disease (GERD), stomach and small intestine ulcers, and inflammation of the esophagus. PPIs work by reducing the amount of acid produced by the stomach.
When were antipsychotics discovered?
Antipsychotic drugs were discovered in the 1950s and currently over 20 compounds are licensed. They vary in clinical effects and especially in unwanted effects. Antipsychotics are classified in a number of ways and this brief guide touches on selected aspects of classification.
What drugs were discovered in 1953?
Discovery of antipsychotic properties of chlorpromazine and its launch in 1953 stimulated synthesis of similar compounds, and introduced drugs such as haloperidol, flupentixol, prochlorperazine, sulpiride and trifluoperazine. These antipsychotics showed worthwhile clinical efficacy in psychosis, such as alleviation of ‘positive’ symptoms ...
What is antipsychotic atypicality?
Originally, antipsychotic ‘atypicality’ was characterised by reduced tendency to cause catalepsy in laboratory animals—this was considered predictive of reduced likelihood of extrapyramidal effects . Following reintroduction of clozapine, antipsychotic development focused on mimicking and improving on its therapeutic effects.
When was Clozapine withdrawn from the market?
The antipsychotic clozapine (first launched in 1972 but then withdrawn over concerns about agranulocytosis) was reintroduced in 1990 for restricted indications because it was found effective for schizophrenia refractory to other antipsychotics; also, extrapyramidal effects seemed less troublesome with clozapine.
Is antipsychotics first or second generation?
However, designating antipsychotics as first-generation and second-generation may be of limited value: it probably exaggerates differences between groups and overstates similarities between members of each group. The implication that second-generation antipsychotics caused fewer adverse effects is not easily sustained.
What is the first generation of antipsychotics?
First-generation antipsychotics are dopamine receptor antagonists (DRA). Dopamine was discovered and categorized as a neurotransmitter in the late 1950s. There are five pathways, or systems, of dopaminergic receptors in the central nervous system.

These include drugs such as Chlorpromazine, Haloperidol, Fluphenazine, etc. Antipsychotic drugs have a salutary therapeutic effect on psychosis.
What is the effect of antipsychotics on psychosis?
Antipsychotic drugs have a salutary therapeutic effect on psychosis. Antipsychotics are also known as neuroleptics and are a class of medication that is used to manage psychosis (including delusions, hallucinations, paranoia or thought disorders), which majorly have been seen in schizophrenia and bipolar disorder.
What is the effect of extra firing of dopamine on schizophrenia?
According to the dopamine theory of schizophrenia, positive symptoms are the result of overactivity in the mesolimbic dopamine pathway.
How long does it take to get off antipsychotics?
Withdrawal from first-generation antipsychotics should be slow and gradual. A period of at least 15–30 days should be considered for this purpose. Nausea, vomiting, psychotic symptoms, hypertension, and sleep disturbances might come back if the sudden discontinuation of therapy occurs.
Which pathway is responsible for the positive symptoms of schizophrenia?
Mesolimbic pathway: Overactivity in this pathway is said to be responsible for the positive symptoms of schizophrenia. The blockade of D2 receptors in the mesolimbic pathway has been the reason for the possible mechanism of antipsychotic action of first-generation agents.
Do amphetamines increase dopaminergic availability?
This is in part based on the observation that drugs that increase dopaminergic availability (L-DOPA, amphetamines) can trigger psychotomimetic effects in individuals not affected by schizophrenia. As a result, they reduce dopaminergic neurotransmission in the four dopamine pathways.
Which antipsychotics cause the greatest risk of seizures?
The antipsychotics with the greatest seizure risk are clozapine and chlorpromazine.2Those with the lowest risk include risperidone, molindone, thioridazine, haloperidol, pimozide, trifluoperazine, and fluphenazine.36.

The three antipsychotics with the greatest risk for hematological complications are clozapine, chlorpromazine, and olanzapine.54Clozapine is associated with an especially high risk for the development of neutropenia or agranulocytosis.54.
Is Clozapine safe for seizures?
However, as indicated earlier, clozapine has a problematic safety profile. For example, patients treated with this drug are at increased risk of developing orthostatic hypotension, which can require close monitoring.2Moreover, high-dose clozapine has been associated with serious adverse effects, such as seizures.2.
Can risperidone cause hyperprolactinemia?
Hyperprolactinemia can occur in up to 87% of patients treated with risperidone or paliperidone, possibly leading to sexual dysfunction, decreased libido, menstrual irregularities, or gynecomastia.2Aripiprazole or ziprasidone is a potential treatment option for patients with increased prolactin levels.39.
Can you take two antipsychotics at the same time?
In combination therapy, two antipsychotic drugs—such as an FGA and an SGA, or two different SGAs—are administered concurrently.2However, exposure to multiple antipsychotics at the same time may increase the risk of serious side effects.24,25,32. Mechanism of Action .

‘Typical’ and ‘Atypical’ Antipsychotics
Chemical Classification
- Antipsychotics can also be divided according to their chemical structure (graphical formulas of selected antipsychotics are shown below). The early antipsychotics, especially the phenothiazines (eg chlorpromazine and trifluoperazine) and the thioxanthenes (eg flupentixol and zuclopenthixol), are structurally related to antihistamines such as promethazine. Many second-generation antips…
Therapeutic Effect Profile
- The precise mechanism of action varies between antipsychotics, but the relevance of this variation to clinical effects has not been fully established. For many antipsychotics, especially the older ones, there is an inverse relationship between affinity for the dopamine D2receptor (particularly in the mesolimbic nuclei) and the dose for antipsychotic effect. Thus, ‘high-potency’ …
Adverse Effect Profile
- Antipsychotics can also be subdivided by their propensity for adverse effects. While dopaminergic D2 antagonism in the mesolimbic area of the brain is though to underlie antipsychotic effect, preferential binding to D2receptors in the nigrostriatal pathway can lead to extrapyramidal effects. Preferential binding to D2receptors in the tuberoinfundibular pathway of the anterior pituitary ca…
