The idea that these two particular meds have a more rapid onset of action when allowed to dissolve in the mouth is a myth. Standard tablets dissolve rapidly in the stomach and are absorbed from the intestine.
Orodispersible olanzapine tablets have two main uses:
1. They are used in inpatient psychiatry for patients with 'compliance issues' eg. spitting tablets out and hiding them.
2. They are useful for those with swallowing difficulties.
Some brands of standard lorazepam tablets dissolve fairly quickly in the mouth and are almost tasteless.
Orodispersible tabs can safety be swallowed whole if you swallow them straight away. Is it not necessary to allow them to disperse... although they normally do so rapidly.
It has been claimed that orodispersible olanzapine causes less weight gain. I find this highly unconvincing. The studies require replication.
Manufacturers are keen to bring out orodispersible tablets mainly as a way of increasing profits via maintenance of market share + charging higher prices.
