Sublingual or Buccal?

There have been many posts talking about various sub-lingual B12 products. Obviously, the very word sub-lingual means that the lozenge (or whatever you want to call it) is placed under the tongue.

Some years ago, I had some Prochlorperazine 3 mg Buccal Tablets. Rather than under the tongue, the instructions state: Place the tablet high up along your top gum, under the upper lip either side of your mouth as indicated above.

medicines.org.uk/emc/PIL.28...

When I decided to try taking B12, I almost automatically followed the same instruction as for Prochlorperazine - only later thinking that this is obviously not what is meant.

Does anyone have any evidence, or even just opinion, on whether buccal is as good as sub-lingual, or even if it might be better? Certainly I find it almost impossible to keep a lozenge sub-lingual for as long as they need.

I'm pretty sure that your last comment is the reason why buccal is preferred to sublingual.

The answer to this is to do with the glands under the tongue and in the inner cheek and the chemical and enzyme differences. I remember someone explaining it to me but that's all I can remember. I would have thought they would dissolve more quickly under the tongue though due to more saliva. Sorry-no evidence

I don't have problems with sublinguals which may be because I tend to pop one in my mouth about 1/2 hour before I get up and just dose until it is gone.

I use a triptan for migraines - which is left to dissolve on the the tongue for a few seconds and is absorbed through the tongue so possible that there are differences with different chemical preparations and compounds.

I am rather assuming there are differences by substance - and, though it might not be as clear as I would have wished, I was specifically asking in relation to B12!

mentioned the triptan as another example of a way that oral membranes are used parallel to Buccal.

ah I apologise. I thought you meant does it really matter which method that you use and are there any real reasons or evidence to say that one is more effective than the other. I was saying that the different glands and what they produce are required for each method. So a sublingual would not be as effective on the gum. :) never mind, I shall leave this discussion as I'm just waffling now
