Yes: Both Ativan and Klonopin (clonazepam) are benzodiazepines and can be used to treat anxiety symptoms. Ativan is shorter-acting than Klonopin (clonazepam) though -- half-life of 8-24 hours compared to 19-60 hours.

Similar & different: Both are "benzodiazepine" tranquilizers, which means they are chemically similar and relieve anxiety by their effect on GABA receptors in the brain. They are also both habit-forming if taken regularly. Comparing the two, Klonopin (clonazepam) is more sedating and lasts longer than the same dose of Ativan (lorazepam).

Yes and no.....: Same chemical class and both help with anxiety; but Klonopin (clonazepam) takes longer to get in your system and take effect and typically lasts longer but leaves your system more gradually, while Ativan gets in and out faster.
