What does a colatapin do?

How close are Xanax to colatapins?

There is no drug known as colatapin. I assume you are refering to Klonopin.Both are benzodiazepines, however they are a bit different in some respects. Klonopin(Clonazepam) lasts a good bit longer than Xanax(Alprazolam). Xanax is better as an "as needed" or "breakthrough panic attacks" since it lasts roughly 6-8 hours, while Klonopin lasts closer to all day, around 16-24 hours and are better for round the clock anxiety control. Xanax tends to make people more drowsy than Klonopin. Both are anxiolytic (like most benzo's) but Klonopin is also an anticonvulsant.Summary: Both have very similar effects and are considered "high potency" benzo's, but klonopin lasts a good bit longer.
