Though both are benzodiazepines, the two drugs are in different classes. Clonazepam is considered a long-acting benzodiazepine, with a rapid onset time of one to four hours and a half-life of approximately 34 hours, while lorazepam is a short-acting benzodiazepine with the same approximate onset time but a half-life of about 15 hours.

I found this:Although most benzodiazepines are used interchangeably, some are most commonly used for certain conditions.
Alprazolam (Xanax), chlordiazepoxide (Librium), chlorazepate (Tranxene), diazepam (Valium), lorazepam (Ativan), and midazolam are used for anxiety disorders;
clonazepam (Klonopin), clorazepate (Tranxene), and diazepam (Valium) are used for seizure disorders;
estazolam, flurazepam, quazepam (Doral), temazepam (Restoril), and triazolam (Halcion) are used for insomnia;
midazolam, lorazepam (Ativan), and diazepam (Valium) are used in anesthesia;
diazepam (Valium) also is used for muscle relaxation;
chlordiazepoxide (Librium) is used for alcohol withdrawal.

To me, that's the difference: Clonazepam helps a whole lot as sleeping aid (for many years) but Lorazepam helps only up to the second sleepness night, than it causes me even more insomnia but each person reacts differently to certain drugs. Sad to say that in the country I leave now I can not buy Clonazepam :(

Lorazepam (Ativan) and Clonazepam (Klonopin) are both strong benzodiazepines with fairly short half lives.
Clonazepam has a half life of about 8-10 hours, while Lorazepam is slightly shorter with a 4-6 hour half life.
Compared to the longest acting half life benzo such as Valium (Diazepam) which is 80-200 hour half life, both are 10-20 times stronger. Strength is measured in half-life, molecular structure and dependence on the GABA receptors.
All benzo's are highly addictive and are the hardest drugs (legal and otherwise) to safely taper from.
* never mix benzodiazepines... clonazepam, ativan, Valium, Xanax. Although in the same class of drugs, their delivery methods and strengths are chemically different.
* Dependency can begin within a few weeks of daily use. Longer use rates of time elapsed will always create dependency/addiction... physically and mentally.
* Benzo's alter your GABA receptors (brain and intestine). These are the command center neurotransmitters that control emotion, physical needs and organ health.
Component differences for Lorazepam - Clonazepam:
Strength... slight to moderate
Half Life... slight to moderate
Addictive properties: High
Tapering protocol in time: 6-18 months (for repeated use more than 3 months on average)
