Neurologic complications of metronidazole
Summary
Metronidazole, an antimicrobial, can cause under-recognized neurological side effects. Early detection and stopping the drug typically lead to complete recovery and resolution of imaging findings.
Area of Science:
- Neurology
- Pharmacology
- Infectious Diseases
Background:
- Metronidazole is a widely used antimicrobial agent.
- While generally safe, it can cause neurological complications.
- These neurotoxic effects are often under-recognized in clinical practice.
Purpose of the Study:
- To review current literature on metronidazole-induced neurotoxicity.
- To summarize clinical syndromes, neuroradiological findings, prognosis, and pathophysiology.
- To emphasize the importance of recognizing these adverse effects.
Main Methods:
- Literature review of studies on metronidazole neurotoxicity.
- Synthesis of clinical and radiological data.
- Analysis of proposed pathophysiological mechanisms.
Main Results:
- Metronidazole can lead to various neurological syndromes.
- Neuroradiological findings are associated with these syndromes.
- Prompt discontinuation of metronidazole is linked to recovery.
Conclusions:
- Metronidazole-induced neurotoxicity is a critical consideration.
- Early recognition and drug cessation are key for patient outcomes.
- Full clinical and radiological recovery is generally expected upon discontinuation.

Local Anesthetics: Adverse Effects
1.0K
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...

Drugs Affecting GI Tract Motility: Dopamine Receptor Antagonists
2.0K
Prokinetic agents are specialized medications that stimulate gastrointestinal (GI) motility, promoting food movement through the GI tract. Dopamine, an inhibitory neurotransmitter, plays a significant role in this process, reducing GI motility and indirectly controlling the speed of digestion. Dopamine receptor antagonists, such as metoclopramide and domperidone, offer a unique advantage as prokinetic agents. By blocking the dopamine receptors, these drugs increase GI motility, improving food...

Hepatic Encephalopathy
71
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...

Drugs Affecting GI Tract Motility: Antimicrobials as Antidiarrheal Agents
603
Acute diarrhea, a common gastrointestinal disturbance, is characterized by the rapid evacuation of fluid stools, leading to an excessive weight in fluid. This condition typically arises from disorders affecting intestinal water and electrolyte transport. It can be triggered by an increased osmotic load within the intestine, excessive secretion of electrolytes and water, mucosal exudation of protein and fluid, or altered intestinal motility. The primary risks of acute diarrhea are dehydration...

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists
1.4K
Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...

Diphtheria
187
Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...
