One way of administering Polygonum Cuspidatum extracts resveratrol in humans may be buccal delivery, that is without swallowing, by direct absorption through tissues on the inside of the mouth. When one milligram of resveratrol in 50 ml 50% alcohol/ water solution was retained in the mouth for one minute before swallowing, 37 ng/ml of free resveratrol were measured in plasma two minutes later. This level of unchanged resveratrol in blood can only be achieved with 250 mg of resveratrol taken in a pill form.[15] However, the viability of a buccal delivery method is called into question due to the low aqueous solubility of the molecule. For a drug to be absorbed transmucosally it must be in free-form or dissolved.[16][17] Resveratrol fits the criteria for oral transmucosal dosing, except for this caveat. The low aqueous solubility greatly limits the amount that can be absorbed through the buccal mucosa. Resveratrol that is attempted to be taken buccally was expected to pass through the mucous membrane of the mouth and be absorbed as an oral dose,[18] however, the need to explore buccal delivery in future pharmaceutical formulations was expressed.[17][19] Polygonum Cuspidatum
While 70% of orally administered resveratrol is absorbed its oral bioavailability is approximately 0.5% due to extensive hepatic glucuronidation and sulfation.[ |
