Síndrome maligno neuroleptico después de la venlafaxina
Lancet (London, England)
|February 16, 2000
Resumen
El síndrome neuroléptico maligno (SNM) puede ocurrir después de una dosis única de venlafaxina y trifluoperazina. La venlafaxina puede aumentar los efectos de bloqueo de la dopamina de la trifluoperazina, lo que lleva a NMS.
Área de la Ciencia:
- La neurociencia es la neurociencia.
- Farmacología Farmacología.
- La medicina clínica es la medicina clínica.
Sus antecedentes:
- El síndrome neuroleptico maligno (SNM) es una reacción rara pero potencialmente mortal a los medicamentos antipsicóticos.
- La venlafaxina, un antidepresivo, y la trifluoperazina, un antipsicótico, son medicamentos comúnmente recetados.
- Comprender las interacciones farmacológicas es crucial para la seguridad del paciente.
Objetivo del estudio:
- Para reportar un caso de NMS después de la administración concomitante de venlafaxina y trifluoperazina.
- Explorar la posible interacción farmacodinámica entre la venlafaxina y la trifluoperazina que contribuye al NMS.
Principales métodos:
- Informe de caso que detalla la presentación clínica, el diagnóstico y el manejo de NMS.
- Revisión de la literatura relevante sobre la farmacología de NMS, venlafaxina y trifluoperazina.
Principales resultados:
- El paciente desarrolló síntomas clásicos de NMS, incluyendo hipertermia, rigidez muscular, inestabilidad autónoma y estado mental alterado, después de una dosis única de venlafaxina y trifluoperazina.
- La aparición de NMS fue rápida, lo que sugiere una interacción farmacodinámica aguda.
Conclusiones:
- La administración concomitante de venlafaxina y trifluoperazina puede precipitar NMS, incluso después de una dosis única.
- El potencial de la venlafaxina para inhibir la recaptación de dopamina puede potenciar los efectos de bloqueo de la dopamina de la trifluoperazina, aumentando el riesgo de EMN.

01:12Local Anesthetics: Adverse Effects
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.

01:30Other Disorders of Digestive System
The gastrointestinal tract is susceptible to various disorders. If the lower esophageal sphincter is damaged, stomach acid can flow back into the esophagus, causing irritation and inflammation of the lining. This condition is called gastroesophageal reflux disease (known as heartburn) and may cause chest pain and difficulty swallowing. In the stomach, prolonged use of nonsteroidal anti-inflammatory drugs like aspirin, chronic alcohol consumption, bacterial infections such as Helicobacter...
01:27Restless Leg Syndrome and Night Terrors
Restless Leg Syndrome (RLS), also known as Willis-Ekbom disease, is a neurological disorder characterized by an uncontrollable urge to move the legs due to uncomfortable sensations. These sensations typically occur during periods of rest or inactivity, particularly when lying down or sitting, and can severely disrupt sleep.
The exact cause of RLS is not fully understood, but it is believed to involve dopamine, a neurotransmitter that helps regulate muscle movement. Imbalances in dopamine levels...

01:19Multiple Sclerosis l: Introduction
Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
01:29Hepatic Encephalopathy
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
