Which alpha blockers may be used to treat PTSD symptoms?
Prazosin and doxazosin belong to a class of medications called ‘alpha-blockers. ‘ Al- pha blockers are only part of the therapy for PTSD. They act to help improve sleep and reduce the nightmares associated with PTSD. They act by blocking alpha-1 receptors in the brain which is thought to lead to better, deeper sleep.
What are the 4 categories that can be triggered by PTSD?
PTSD symptoms are generally grouped into four types: intrusive memories, avoidance, negative changes in thinking and mood, and changes in physical and emotional reactions. Symptoms can vary over time or vary from person to person.
What is the difference between Alpha 1 and Alpha 2?
Alpha 1 receptors are the classic postsynaptic alpha receptors and are found on vascular smooth muscle. Alpha 2 receptors are found both in the brain and in the periphery. In the brain stem, they modulate sympathetic outflow.
What is the difference between doxazosin and prazosin?
In contrast to prazosin, the “me-too” medication doxazosin has a half-life of 16 to 30 hours and, therefore, can be taken once daily with no extra daytime dosing required. In contrast to prazosin, doxazosin has an improved absorption profile, which likely minimizes the risk for hypotension.
What is the difference between alpha-blockers and beta blockers?
Alpha-blockers work on the blood muscles to open up the blood vessels, while beta-blockers work on the heart to ease the flow of blood. Alpha-blockers work on norepinephrine or noradrenaline, while beta-blockers work on epinephrine or adrenaline.
Why is tamsulosin preferred over prazosin?
Tamsulosin and prazosin are both effective in palliating symptoms of women with voiding dysfunction and improving their urodynamic parameters. Tamsulosin may be the preferred drug to prescribe because of its more amenable side effect profile and greater patient satisfaction.
