Historical Background and Discovery
Triflupromazine was first created in the 1950s as one of the emerging medications. Its development aimed to improve the symptoms of disorders, making it a significant contribution to psychopharmacology throughout history.
Classification and Chemical Structure
Triflupromazine falls under the category of medications known as phenothiazines. Its chemical structure sets it apart, consisting of three interconnected rings containing nitrogen and sulfur atoms.
II. Uses of Triflupromazine
Primary Indications: Why It's Prescribed
Triflupromazine is a type of phenothiazine drug that is used to treat schizophrenia and other psychotic disorders by blocking dopamine receptors in the brain. It can help reduce symptoms such as hallucinations, delusions, anxiety, and emotional withdrawal.
Comparison with Other Antipsychotic Medications
- Triflupromazine binds to the dopamine D1 and dopamine D2 receptors and inhibits their activity1. It is used for severe emesis and severe hiccups2.
- Risperidone and aripiprazole are both antipsychotics that act on dopamine and serotonin receptors, but have different pharmacokinetic profiles3. Risperidone may increase the hypotensive effects of aripiprazole4. Aripiprazole may have no advantages over risperidone for negative symptoms of schizophrenia5.

III. How Triflupromazine Works
Mechanism of Action
Triflupromazine primarily works by inhibiting the dopamine receptors in the brain specifically targeting the subtype. This helps to regulate dopaminergic activity that is often seen in individuals, with schizophrenia.
Impact on Neurotransmitters
In addition to dopamine, it also influences neurotransmitters such as serotonin, making it a versatile agent. This wide range of interactions with neurotransmitters contributes to its effectiveness.
Biological Effects and Neural Pathways Involved
Triflupromazine impacts neural pathways, specifically the mesolimbic and mesocortical pathways. These pathways play a role, in managing emotions and cognitive abilities, respectively.
IV. Off-Label Uses
Recognized Off-Label Treatments
- Triflupromazine is a phenothiazine antipsychotic that has sedative and antiemetic effects1. It is not approved for anxiety or agitation, but it may be used off label in some cases2.
- Anxiety and agitation are common and distressing symptoms that require prompt recognition and management34. There are various pharmacological options for treating these conditions, such as benzodiazepines, classic antipsychotics, or atypical antipsychotics5.

Evidence and Research Supporting Each Off-Label Use
- Triflupromazine is a phenothiazine antipsychotic that has sedative and antiemetic effects1. It is used mainly in the management of psychoses, but also to control severe nausea and vomiting, severe hiccups, and moderate to severe pain in some hospitalized patients12.
- Triflupromazine has been supported by multiple case studies and retrospective analyses for its effectiveness in treating these conditions that are not officially approved34. However, it is crucial to conduct clinical validation for these uses, as triflupromazine has a higher risk for side effects than many other antipsychotics and may cause extrapyramidal reactions25.

Controversies and Concerns
While the use of medications for purposes, than their approved indications is frequently mentioned it raises concerns regarding ethical and legal implications particularly when adverse effects arise.
V. Dosage and Administration
Standard Dosing Guidelines
The recommended daily dosage for adults usually falls within the range of 15 to 40 mg, divided into daily doses. Adjusting the dosage based on an individual's response and tolerance levels is essential.
Adjustments for Specific Populations
Sometimes when it comes to groups like older people or individuals with kidney problems, it's often necessary to change the dosage. These adjustments are typically determined by looking at clearance and conducting tests on liver function.
Routes of Administration: Oral, Intramuscular, etc.
Triflupromazine comes in forms, such as tablets that can be taken orally and solutions that can be injected into the muscles. Each method has unique characteristics regarding how the drug is absorbed and its recommended uses in clinical settings.
Dosing Frequency and Timing
The usual practice for taking the medication involves splitting it into two or three doses spread out during the day. However, there might be cases where specific protocols differ from this general recommendation.
Active and Inactive Ingredients
The main component, which is Triflupromazine, is responsible for the effects. On the other hand, the additional elements usually consist of substances, like lactose and magnesium stearate, used as fillers and binders.
Available Forms: Tablets, Solution, etc.
Triflupromazine is available in formats, including tablets for oral consumption and solutions for injection. These different options provide flexibility in meeting a range of requirements.
Recommended Storage Conditions
The medication needs to be kept in a cool place at room temperature to ensure that it retains its effectiveness. It's essential to store it from any moisture or direct sunlight. Maintaining storage conditions is critical to the drug's pharmacological efficacy.
Stability and Shelf Life
Triflupromazine typically remains usable for around two to three years after it has been manufactured, as long as it is stored according to the recommended conditions.
To ensure the safety of the environment it is essential to dispose of unused medication following the guidelines provided by local authorities for pharmaceutical waste disposal.
Drugs that Increase or Decrease Triflupromazine’s Effects
Some medicines, such as anticholinergics, can enhance the impact of Triflupromazine, while substances, like carbamazepine, might lower its effectiveness.
Potential Food and Alcohol Interactions
It is generally not recommended to mix Triflupromazine with alcohol or grapefruit juice because it may increase the risk of experiencing side effects.
Interactions with Herbal Supplements
Natural remedies such as St. Johns's Wort can interact with Triflupromazine, which can sometimes reduce its effectiveness in treating conditions.
IX. Side Effects
Common Side Effects: Prevalence and Severity
Some effects you may experience include feeling sleepy and having a dry mouth. Although they are usually not severe these effects can affect your well-being and may require some measures to alleviate the symptoms.
Less Frequent but Severe Side Effects
Rare but serious adverse effects such as dyskinesia and neuroleptic malignant syndrome necessitate prompt medical attention.
Long-term Risks and Side Effect Management
Extended use of this treatment may lead to the development of metabolic syndromes and cardiovascular complications. As a result, it is essential to evaluate its effectiveness and safety.
X. Warnings and Contraindications
Situations where Triflupromazine Should Not be Used
Triflupromazine should not be used in patients who have a known sensitivity to phenothiazines. It should also be avoided when the patient is in a coma or when there are high central nervous system depressants, like alcohol.
Conditions that May Exacerbate with Its Use
Triflupromazine could worsen existing health conditions such as Parkinson's and narrow-angle glaucoma. For instance, it may lead to increased blood pressure in individuals with hypertension, heightened motor symptoms in those with Parkinsons' Disease and potentially trigger acute episodes in individuals with narrow-angle glaucoma.
Pre-existing Diseases or Disorders of Concern
Individuals with liver problems, kidney issues or a past of seizures should use care and seek advice from a healthcare professional to develop a personalized treatment approach.
XI. Careful Administration
Monitoring Parameters While on Triflupromazine
Regularly monitoring parameters is crucial, including liver function tests such as AST, ALT, and bilirubin levels. Additionally, checking creatinine and BUN levels is essential to keep an eye on function. Lastly, a complete blood count should be conducted to assess hemoglobin levels, hematocrit levels, and white blood cell count.
Necessary Laboratory Tests and Screenings
To ensure the heart's health, they may also conduct ECG monitoring. Regularly check the eyes for any visual problems.
XII. Important Precautions
Potential Risks and How to Minimize Them
To minimize risks, it is recommended to refrain from engaging in tasks that demand mental attentiveness like driving until the individual has fully adjusted to the impact of the medication.
Necessary Lifestyle and Dietary Adjustments
