Ativan vs Clonazepam vs Valium vs Xanax: Full Comparison of anti-anxiety drugs
Millions of adults in the world experience anxiety disorders, including some isolated panic attacks and persistent generalized anxiety. Although therapy and lifestyle modification are very important, medications are mostly prescribed when the symptoms become an obstacle to normal daily life.
Some of the most prescribed types of anti anxiety drugs include Ativan (Lorazepam), Clonazepam (Rivotril), Valium (Diazepam), and Xanax (Alprazolam). The four drugs have great differences in strength, duration, medical application, and safety of usage; despite being of the same drug class.
This plan is a straight-forward doctor-style comparison in order to get a better understanding of the difference between these medications and when each is to be given.
Learning Benzodiazepines: The Common Mechanism
The four medicines all fall under the benzodiazepine category. They have the effect of boosting the action of GABA, (gamma-aminobutyric acid), a neuro-transmitter that quiets down the overactivity of the brain.
This results in:
- Reduced anxiety
- Muscle relaxation
- Sedation
Anti-seizure effects (in others)
They do not behave clinically in a similar way, although sharing the same mechanism.
