Key differences
Ativan belongs to Anti-anxiety Medications while Neurontin belongs to Neurological Medications. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Ativan: Lorazepam binds the benzodiazepine site of the GABA-A receptor and allosterically enhances inhibitory chloride conductance. Neurontin: Gabapentin binds the alpha-2-delta auxiliary subunit of voltage-gated calcium channels in the central nervous system, reducing presynaptic calcium influx and the release of excitatory neurotransmitters such as glutamate…
When Ativan is preferred
Ativan is approved in adults for the short-term management of anxiety disorders and anxiety-related insomnia.
When Neurontin is preferred
Neurontin is approved in adults and children aged 3 years and older as adjunctive therapy for partial-onset seizures, and in adults for post-herpetic neuralgia.
Frequently asked questions
