Common Drugs Used To Treat Schizophrenia

Overview of Latuda a Prescription Medication Used to Treat Schizophrenia and Depression

Unfortunately, the cause of schizophrenia is still up for debate, but the disorder is treatable. When individuals are prescribed medication and take it accordingly, then usually progress is made, and normal daily life can be enjoyed. Antipsychotic medications are a common prescription for individuals diagnosed with schizophrenia. These medications are believed to reduce the psychosis symptoms by affecting the brains neurotransmitter dopamine, which relieves hallucinating, delusional thoughts, paranoia, and even disorganized thinking.

Although the medications work well for multiple symptoms, other treatments can be more effective with motivational issues, social withdrawal, and lacking emotional expression. There is also a multitude of differences in medications. There are first-generation antipsychotics and second-generation antipsychotics. However, second-generation medication is usually preferred because of the lower risk of serious side effects compared to the first-generation.

How Do Antipsychotic Medications Work

It is thought that dopamine is a contributing factor to the development of psychosis. Dopamine is one of the many chemicals present in the brain that carry messages from one part of the brain to another.

Dopamine, among other things, is involved in how a person:

  • knows that something is significant, important or interesting
  • experiences pleasure and reward
  • feels motivated.

It is also involved in the control of our muscles and movement.

It is thought that high levels of dopamine may cause the brain to function differently and may cause the symptoms of psychosis.

Antipsychotic medications reduce the amount of dopamine in the brain or restore the balance of dopamine with other chemicals in the brain.

Identification Of Signs And Symptoms

Regardless of which dominant expression schizophrenia takes, signs and symptoms are divided into four main quadrants. This helps simplify the often painstakingly detailed, tedious process of disentangling a complex equation of interwoven symptoms. The quadrants are, in no particular order:

  • Cognitive symptomsare characterized by the inability to appropriately use language, difficulty learning, chaotic, disorganized thinking, and faulty beliefs .
  • Behavioral symptomsare characterized by social withdrawal, self-imposed isolation, irrational fear of eating, drinking, or touching others, loss of motivation, neglected personal hygiene, erratic, unpredictable and disturbing behavior, and dangerous impulsivity.
  • Emotional symptomsare characterized by a flat, emotionless expression , nonsensical responses, lacking empathy or patience with others, and erratic mood shifts.
  • Sensory symptomsare characterized by seeing things that do not exist, otherwise known as visual hallucination, or hearing voices that are inaudible to others and imaginedauditory hallucination. In many schizophrenics, both auditory and visual hallucinations occur simultaneously.

Side Effects Of The Medications Used To Treat Schizophrenia


In-depth look at the major side effects of antipsychotic medications.

All medications have side effects. Different medications produce different side effects, and people differ in the amount and severity of side effects they experience. Side effects of antipsychotic medications can often be treated by changing the dose of the medication, switching to a different medication, or treating the side effect directly with an additional medication.

Common inconvenient side effects of all antipsychotic drugs used to treat schizophrenia include:

  • dry mouth

Some people experience sexual dysfunction or decreased sexual desire and menstrual changes.

Atypical Antipsychotics Linked to Diabetes

One of the most frequent complaints about atypical antipsychotics is that they induce significant weight gain. Because atypical antipsychotic drugs may increase the risk of obesity, diabetes, and high cholesterol, the FDA told makers of the drugs to include these risks in product labels.

Other common side effects relate to muscles and movement problems. These side effects include restlessness, stiffness, tremors, muscle spasms, and one of the most unpleasant and serious side effects, a condition called tardive dyskinesia.

Nicotinic Receptors In Schizophrenia

Many people suffering from schizophrenia smoke. This can be attributed to the disease itself or its treatment . There are numerous reports about disturbed brain cholinergic transmission in patients with schizophrenia . Patients communicate that smoking helps them to relieve negative symptoms which can be linked to their deficiencies regarding nicotinic receptors.

The high rate of smokers among patients with schizophrenia stimulated the research on the role of nicotinic receptors in this disorder . Studying of 7 receptors with specific venomous toxins showed that 7 receptors are located in brain regions involved in cognition . Deterioration of cognitive abilities such as working memory and cognitive flexibility, as well as attention, anticipate psychotic symptoms and are a prognosticator of functional outcome .

The results of trials with 7 nicotinic receptor agonists or positive allosteric modulators are promising but require further investigation.

Side Effects Of Antipsychotic Medications

Antipsychotic medications should come with a leaflet about the specific medication prescribed. This includes information on side effects and what to do if they are overwhelming.Possible side-effects of antipsychotics include:

  • dry mouth
  • weight gain that can lead to diabetes

Schizophrenia And Polysubstance Abuse

Polysubstance drug abuse involving mind-altering substances such as potent opiates and illicit street-drugs can have a dramatically negative effect on schizophrenia. Even in individuals with relatively normal genetics and a strong physical constitution, polysubstance drug abuse can take a crippling toll. With regard to schizophrenia, specifically, the disorganized thought patterns, auditory and visual hallucinations, erratic behaviors, and communication difficulties react with far greater volatility to the presence of mind-altering substances and create long-term damage.

The already disjointed, neurologically dysfunctional brain of a schizophrenic is not designed to withstand the assault of hard-core substances. Although typical antipsychotic medications such as Haldol and Proxilin, and atypical antipsychotic medications such as Seroquel and Risperdal can be very effective in alleviating certain symptoms of schizophreniathey interact badly with mind-altering substances and run the risk of producing serious, potentially fatal, complications. For this reason, it is imperative that individuals suffering from schizophrenia refrain from any unnecessary drug use.

Where To Find Treatment

It depends upon the drug taken, its dose, and how frequently it has been consumed. So is the case with psychotics. Psychotics can never be confused with mild drugs because the light or soft drugs can never manage any psychotic disorder. Therefore, antipsychotics are powerful and strong drugs which the patients with psychosis have to consume regularly. The intake of any drug, either mild or strong, regularly can more than likely show its side effects at a certain stage or period.

But still, there are certain patients with such pathetic and strong symptoms of Schizophrenia who tend to bear the pain caused by side effects to make the symptoms of the disease go away.

The side effects of these antipsychotics may include:

  • Increased heart rate
  • Feeling dizzy occasionally as well as experiencing fatigue quite regularly.
  • The user might also feel sensitive to the sun and can experience skin rashes.

In addition to the above-mentioned mild symptoms of antipsychotics, there are certain other side effects observed too, which have proved to be more serious.

  • Frequent restlessness
  • Tremors or shaking
  • Rigidity

Antipsychotics: Medications That Tame Psychosis

The medications doctors prescribe most often for schizophrenia are called antipsychotics. They ease symptoms such as delusions and hallucinations.

These drugs work on chemicals in the brain such as dopamine and serotonin. You can get them during an episode to help relieve psychosis quickly, and also take them long term to prevent symptoms.

You’ll most likely have to take schizophrenia medication your entire life, even if your symptoms get better. You can take antipsychotics as a liquid, a pill, or as an injection.

If you think you might have trouble remembering to take medicine every day, you can try a shot you get from your doctor once or twice a month called a long-acting injectable antipsychotic medication . It works just as well as taking a daily pill.

Doctors will choose which medication is best by looking at the following:

  • How well it works on your symptoms
  • How much it will cost
  • Side effects
  • How easily you can get it
  • How often you have to take it

Your doctor may adjust your dosage over time and might change the medication you take, depending on how you respond. In some cases, your doctor will prescribe more than one kind of antipsychotic drug.

Antipsychotics work best on “positive” symptoms like hallucinations and delusions. They may be less effective on “negative” symptoms like withdrawal and lack of emotion.

Which Antipsychotic Medicine Will Be Best For Me

People respond differently to different antipsychotic medicines some work well for one person but not so well for another. Or side effects may be a problem with one medicine but less so with another. So, treatment for schizophrenia is tailored specifically for each individual.

In Australia, antipsychotics are available only on prescription. The medicine that your doctor or psychiatrist prescribes will depend on:

  • your symptoms and how long you have had them
  • likely side effects of medicines
  • your age and sex and
  • whether you have any other conditions or take other regular medicines.

Sometimes the first antipsychotic medicine you try wont be effective or will cause troublesome side effects, so you may need to change medicines. Your doctor will work with you to find the best medicine for you and the right dose.

A second-generation antipsychotic is usually the first choice for people who are having a psychotic episode for the first time. If the first medicine tried is not effective in controlling symptoms, a different second-generation or a first-generation antipsychotic may need to be tried.

Its usually recommended that people take antipsychotic medicines for 2 to 5 years after a psychotic episode. After a certain period of time , some people may be able to have a trial of no medicines under their doctors supervision. If they remain symptom free, they may not need to take long-term medicines.

Delivery Of Antipsychotic Medications


Most antipsychotic medications are taken in tablet form, but can also be taken in syrup or liquid form, or as an injection . Depot injections contain the same medications as those found in pill or liquid form. They are given in a carrier liquid that releases the medication slowly, so it lasts a lot longer. This can occur over several weeks. Not all antipsychotics are available as depot injections.Depot injections might be helpful where:

  • a person has difficulty remembering to take their medication regularly or may take the wrong dose
  • a person might have difficulty swallowing medication in tablet form
  • the person would prefer not to have to think about taking medication every day
  • medication might be a condition of a court community-treatment order.

It is important to discuss with your doctor the different treatment options available, and which of them might be the best for you.

Whichever delivery method you choose, do not suddenly stop taking antipsychotic medication without speaking with a mental health professional, as psychotic symptoms may return.

Classical Approaches To Treat Schizophrenia

The same drugs are also used to treat brain damage, mania, toxic delirium, agitated depression and other acute behavioral disturbances. In terms of pharmacology, most are antagonists of dopamine receptor, although many of them also have an affinity for other targets, especially serotonin receptors, which may have an impact on their clinical efficacy. Currently available drugs have many drawbacks when it comes to their efficacy and side effects. Even though gradual improvements with newer drugs have been achieved, radical new approaches require a deeper understanding of the pathomechanism and causes of the disorder that are still insufficiently understood .
