Softgel

Abstract: The relative bioavailability of typical commercially available forms of coenzyme Q10 (CoQ10) was compared with that of Q-Gel, a new solubilized form of CoQ10, in human subjects in two separate trials. In the first, standard softgel capsules containing CoQ10 suspension in oil, powder-filled hardshell capsules and powder-based tablets were tested along with Q-Gel using a daily dosage of 120 mg for three weeks. The baseline plasma CoQ10 values were all very tight (0.50-0.52 microgram/mL) and after three weeks the values were 1.37, 1.63 and 1.60 micrograms/mL for the first three products and 3.31 micrograms/mL for Q-Gel. The relative bioavailability calculated using the areas under the plasma CoQ10 curve (AUC) were (micrograms/mL x time in days) 7.16 (100%), 8.97 (125%), 9.19 (128%) and for Q-Gel 22.86 (319%). The second trial, carried out to replicate the findings in the first, employed only two groups, namely the standard softgel capsules containing the suspension and Q-Gel, and the duration was extended to four weeks. Plasma CoQ10 values were: baseline 0.40 and 0.38 and after four weeks 1.26 and 2.80; the corresponding AUCs were: 8.33 (100%) and 22.75 (273%). Thus, the data from both the trials show that Q-Gel, the new solubilized form of CoQ10, is vastly superior to typical commercially available preparations of CoQ10. This means much lower doses of Q-Gel will be required to rapidly reach and maintain adequate blood CoQ10 values than with any of the other currently available products.

Abstract: Levothyroxine is recognized as the treatment of choice for hypothyroidism. So far, the tablet levothyroxine has been the formulation almost exclusively used, even though an optimal daily dose of levothyroxine has been unsuccessfully sought and a consensus not achieved. Due to progressive use of a more individually tailored levothyroxine dose, increasing evidence has instead displayed that many gastrointestinal disorders, polypharmacy, and food interference may raise the daily levothyroxine requirement. In recent years, alternative levothyroxine formulations have become available and have rapidly gained attention because of their pharmacokinetic properties. This study aims to provide an overview regarding the use of softgel capsule and/or liquid levothyroxine solution while performing a review of published studies about such topic. A comprehensive computer literature search of the PubMed/MEDLINE, Scopus, and Google Scholar databases has been conducted to find published articles on this topic. The search algorithm was based on the combinations of the following terms: "oral solution" or "soft gel" or "liquid", and "levothyroxine". The computer search resulted in 75 articles; through a critical review of such titles and abstracts and a screening of their references lists, the review included 18 original articles relating to 800 patients treated with alternative formulations. Despite some limits, the results obtained using softgel and liquid levothyroxine were consistent with each other. In selected categories of levothyroxine-treated patients (pediatric, suffering from hypo-achlorhydria, polypharmacy, undergone bariatric surgery, fed through enteric tube) these new formulations have shown promising attributes in improving a treatment that needs to be individually tailored.
