What is the relationship?
Klonopin and Lorazepam are different things: Klonopin is a branded medication whose active ingredient is Clonazepam (in the Anti-anxiety Medications class), whereas Lorazepam is in the Benzodiazepine class.

Mechanisms compared
Klonopin: Clonazepam binds to the benzodiazepine site of the GABA-A receptor and allosterically enhances inhibitory chloride conductance, hyperpolarising central nervous system neurons. Lorazepam: Lorazepam binds the benzodiazepine site of the GABA-A receptor and allosterically enhances the action of the inhibitory neurotransmitter GABA.
