Abstract:
Most Coenzyme Q10 dosage forms exhibit negligible dissolution
indicating potentially poor bioavailability. In order to improve its dissolution
profile and thereby its absorption, a new process (Bio-Solv ®)
was employed to produce Q-Gel ® Softsules. This novel formulation
in the form of a softgelatin capsule passes the dissolution test
via USP testing methodology. When compared with other commercially available
dosage forms for relative bioavailability in human subjects, Q-Gel ® was found to be vastly superior (a 6 fold increase in plasma CoQ10
values over baseline, and several fold greater relative bioavailability over
other dosage forms tested).
Coenzyme Q10 (Ubiquinone) is a lipid-soluble compound found in the mitochondria
of all living cells. It also occurs in the food chain and is endogenously
produced in the liver. There are conditions in which adequate production
of CoQlO in the body is impaired, and in such situations supplementation
with CoQ10 has been shown to be very beneficial.
CoQlO, being lipid soluble, follows the same pathway as that of fats
for its absorption in the body. This involves emulsification in the intestine
(with the help of bile salts) and the formation of micelles prior to absorption.
Among the other factors affecting the absorption of exogenously administered
CoQlO are its particle size, degree of solubilization, and the type of
food ingested with the supplement.
Although CoQlO is classified as a lipid soluble substance, its degree
of solubility is extremely limited. Commercially available CoQlO capsules
contain either oil-based suspensions (softgels), or dry powder blends (hard
gels). When tested in the laboratory, these products show a total lack
of dissolution according to current USP methodology. Such lack of dissolution
properties are often indicative of poor absorption and bioavailability.
In order to improve the dissolution profile and bioavailability of CoQl0,
Tishcon Corp. has acquired an exclusive technology/process
from BioSytes, USA, Inc. This novel Bio-Solv® process has provided
the key to the solubilization of CoQlO. Q-Gel® softsules®
based on the Bio-Solv® process exhibit optimum
dissolution, which is indicative of improved absorption/bioavailability.
Several human studies have been subsequently carried out to compare the relative bioavailability
of Q-Gel® with other currently available dosage forms (softgels,
tablets and capsules), and the data obtained from these studies clearly demonstrate
that Q-Gel® is vastly superior (several times higher relative
bioavailability than all other dosage forms tested).
These data were presented at the Annual Meeting of the American Society
for Nutritional Sciences/Experimental Biology in New Orleans on April 9,
1997.
