Zolpidem - I accidentally swallowed my nocte tablet tonight instead of letting it dissolve?

When you take a medication sublingually it gains faster and more direct access to your bloodstream via the many capillaries (small blood vessels) in the floor of your mouth. This leads to a faster and often increased therapeutic effect as compared to taking the medication orally (swallowing). Accidentally swallowing your sublingual tablet should not be dangerous because it won’t enhance absorption by going through your GI tract. If anything, it’s more likely you will get less of a dose in your bloodstream than if you had taken it as directed.

Hello-

Probably has to do with absorption time, if you let things dissolve they can be absorbed faster than if consumed as a solid generally. I wouldn't be to concerned as long as the dose is the same.
