Final answer:
Alprazolam (A) and Propanolol (B) can be used to treat symptoms of PTSD.
Step-by-step explanation:
Two of the medications listed have direct uses in treating symptoms common in PTSD: Alprazolam (A) and Propanolol (B).
Alprazolam is a benzodiazepine, specifically used to treat anxiety disorders like PTSD. It works by increasing the calming effect of a neurotransmitter called GABA in the brain.
Propanolol is a beta-blocker that is commonly used to manage physical symptoms of anxiety, such as rapid heartbeat and sweating. It can help reduce the physiological response to traumatic reminders or triggers for individuals with PTSD.
