  • REBEL Cast Ep115 – Phenobarbital vs Lorazepam in Alcohol Withdrawal
    by Cara Borelli DO on March 23, 2023 at 12:00 pm

    Background information: Alcohol has potentiating effects on the inhibitory GABA neurotransmission system and inhibitory effects on the excitatory glutamate neurotransmission system. Chronic alcohol use causes changes to preserve homeostasis, and when the stimulus is removed, alcohol withdrawal results due to decreased inhibition via the GABA system and increased excitation via the glutamate system. Treatment options ... Read more The post REBEL Cast Ep115 – Phenobarbital vs Lorazepam in Alcohol Withdrawal appeared first on REBEL EM - Emergency Medicine Blog.

    by Nadia Adside, MD on January 23, 2023 at 1:00 pm

    Background: Diphenhydramine, a first-generation antihistamine, is the most common pharmacologic agent used to treat acute allergic reactions. Despite being highly effective in treating acute allergic reactions, first-generation H1 antihistamines cross the blood-brain barrier and bind to H1 receptors, which can lead to undesirable side effects, including drowsiness, sedation, fatigue, and decreased cognition (Church MK 2010). ...
