Benzodiazepines
Benzodiazepines samer kareem 3,967 Views • 2 years ago

Benzodiazepines are a class of agents that work on the central nervous system, acting selectively on gamma-aminobutyric acid-A (GABA-A) receptors in the brain. GABA is a neurotransmitter that inhibits or reduces the activity of nerve cells (neurons) within the brain. Benzodiazepines open GABA-activated chloride channels, and allow chloride ions to enter the neuron. This makes the neuron negatively charged and resistant to excitation.

Serotonin Syndrome
Serotonin Syndrome samer kareem 3,356 Views • 2 years ago

Symptoms of serotonin syndrome include a classic triad of mental status changes (eg, anxiety, delirium, confusion, restlessness), autonomic dysregulation (eg, diaphoresis, tachycardia, hypertension, hyperthermia, diarrhea, mydriasis), and neuromuscular hyperactivity (eg, hyperreflexia, tremor, rigidity, myoclonus, ocular clonus). Serotonin syndrome is clinically diagnosed and laboratory tests are used to rule out other etiologies. It usually occurs due to inadvertent interactions between drugs, therapeutic use of multiple serotonergic agents, or serotonergic medication overdose. Treatment involves discontinuation of serotonergic drugs, supportive measures, and sedation with benzodiazepines. In severe cases, a serotonin antagonist (cyproheptadine) may be used.

This patient's gradual onset of neurologic symptoms (slurred speech, confusion, tremors, and ataxia) is consistent with chronic lithium toxicity. Therapeutic lithium levels are 0.8- 1.2 mEq/L. Serum lithium levels >1.5 mEq/L confirm toxicity, and levels ;::2 .5 mEq/L require emergency management.
