Curcuma longa and Boswellia serrata Phytosome

2022
For the clinical study, the sunflower lecithin-based formulation of Curcuma longa L. and Boswellia serrata standardized extracts (CBP, 500 mg) was prepared by Indena S.p.A., Milan, Italy, as oblong-shaped, film-coated tablets, corresponding to a content of 17.0–23.0% w/w of curcumin and 7.0–11.0% w/w of boswellia extracts, respectively, by high performance liquid chromatography (HPLC) assay [34 (link)]. The active ingredient was a solid dispersion containing the standardized association of curcumin extract (≥90% as total curcuminoids assessed by HPLC assay) and boswellia extract (≥65.0% of total triterpenic acids assessed by HPLC assay). The remaining food-grade components of the phytosome tablets are calcium carbonate E170 (95DC M; Dr Paul Lohman®, Emmerthal, Germany), polyvinylpolypyrrolidone E1202 (Polyplasdone XL; Ashland, Austria, Germany, United States), sodium croscarmellose E468 (Solutab® A-IP; Blanver Farmoquimica LTDA, Taboão da Serra, Brasil), silicon dioxide E551 (Syloid® 244FP; Grace, Columbia), talc E553b (Mondo Minerals B.V., Amsterdam, Netherlands), magnesium stearate E470b (Ligafood®; Peter Greven, Bad Muenstereifel, Germany), and hydroxypropyl methylcellulose E463-based film-coating (Opadry® Clear; Colorcon, United Kingdom). Before releasing, the film-coated tablets containing the food-grade lecithin formulation were tested for appearance, average mass, uniformity of mass, HPLC-content of curcumin and boswellia extracts, disintegration time, and microbiological quality.

Bergamot and Artichoke Combination Supplement

2021
For the clinical study, 600 mg of bergamot (Cytrus bergamia polyphenols) phytosome® and 100 mg of artichoke (Cynara cardunculus L.) leaf standardized dry extract [15 (link)] were formulated by Indena S.p.A. (Milan, Italy) into film-coated tablets containing the following ingredients: dicalcium phosphate dihydrate (Di-Cafos® D160, Budenheim, Germany), magnesium carbonate (Dr. Paul Lohmann GMBH, Emmerthal, Germany), polyvinylpolypyrrolidone (PolyplasdoneTM XL, Ashland Special Ingredients, Wilmington, DE, USA), sodium croscarmellose (Solutab® A-IP, Blanver Farmoquimica Ltd., Taboão da Serra, Brazil), silicon dioxide (Syloid® 244FP, Grace GMBHGmbH, Worms, Germany), talc (Microtalc Pharma 50, Mondo Minerals B.VBV, Amsterdam, The Netherlands), and magnesium stearate (Ligafood®, Peter Greven, Venlo, The Netherlands). Tablets were coated with a hydroxypropylmethylcellulose-based film coating system (Opadry® Clear, Colorcon Inc., Indianapolis, IN, USA).
The film-coated tablets were analyzed for appearance, HPLC assay, uniformity of mass, disintegration time, heavy metals, and microbiological quality.
Control is represented by film-coated tablets with the same shape, color, flavor and taste as the intervention tablets.
The supplementation regimen was 2 daily tablets, one before lunch and one before dinner, for 2 months (as for a 60-day continuous integration). Compliance to the supplementation regimen was defined as the number of tablets actually taken by each subject divided by the number of tablets that should have been taken over the course of the study. Adverse events (AEs) were based on spontaneous reporting by subjects as well as open-ended inquiries by members of the research staff. Safety was assessed by laboratory tests performed at baseline and end of treatment (EoT) detailed below, and by recording volunteered adverse events.

Tailored Copper Gluconate Enteric Coatings

2021

Example 5

A second dissolution target was established for patients with higher stomach pH levels, e.g., patients undergoing proton pump inhibitor treatment concurrent with chemotherapy. The coated copper gluconate minitablets discussed above were further coated with a coating that dissolves as a function of time (e.g., exhibits pH-independent swelling) to provide additional protection against copper gluconate dissolution in the stomach. Coating studies were performed on copper gluconate minitablets coated with: a) Opadry® (4.5% W.G.) and Eudragit® FS 30 D (12% W.G.); b) Opadry® (4.5% W.G.), Eudragit® FS 30 D (12% W.G.) and Eudragit® RL (2%, 4%, and 6% W.G.). Eudragit® RS 30D and Eudragit® RL 30D are pH-independent polymers. Both Eudragit® RS 30D and RL 30D are composed of ethyl acrylate, methyl methacrylate, and a low content of methacrylic acid ester with quaternary ammonium groups. Eudragit® RL 30D contains more ammonium groups than Eudragit® RS 30D, thus it has faster water permeability than Eudragit® RS 30D.

Minitablets were produced as follows: 2 kg of copper gluconate powder blend was prepared and around 1.4 kg of copper gluconate minitablets was obtained for coating trials after the process of tableting. Due to the low weight variation (>95% of tablets within target weight±7.5%) observed on tablets produced by the tablet press, these minitablets were directly used for coating trials without evaluating weight. The minitablets were first coated with 4.5% weight gain of Opadry® Clear (Colorcon, Calif.) and 12% weight gain of Eudragit® FS30D (Evonik, N.J.). The initial dissolution testing was performed as follows: three coated copper gluconate tablets were put in a size 00 Licaps® gelatin capsule prefilled with four disulfiram tablets (10 mg of disulfiram each). These capsules were then packaged in a 60 cc bottles for stability testing. Results are shown in Table 18.

Minitablets pre-coated with Opadry® Clear 4.5% W.G. and Eudragit® FS30D (12% W.G.) were then further coated with 2%-10% weight gain of Eudragit® RL30D (Evonik, N.J.). Dissolution testing was performed and drug recovery was determined every hour between 1 h and 8 h. The results presented in Table 19 and FIG. 6 show that the additional coating of Eudragit® RL30D of 2,%, 4% or 8% weight gain successfully delayed the release of copper beyond the minitablets coated with Opadry® Clear and 12% weight gain of Eudragit® FS30D alone. In particular, the copper gluconate tablets coated with Eudragit® FS (12% weight gain) and Eudragit® RL (2% weight gain) displayed no copper release in 0.1 N HCL and 91.03% recovery after 3 hours in sodium citrate pH 7.4.

Dissolution testing was also performed on minitablets coated with pH-sensitive coats that exhibit swelling at higher pH. To assess coat combinations that may provide drug recovery at higher pH, copper gluconate minitablets were coated with Opadry® (3% W.G.) and Eudragit® FS 30 D (4% or 6% W.G.), Table 20. Eudragit® FS 30 D is a pH-dependent coating that allows drug release at pH>7. The copper gluconate minitablets coated with Opadry® (3% W.G.) and Eudragit® FS 30 D (4% W.G.) demonstrated 88.18% release of copper after 2 hours in sodium citrate pH 7.4 and 95.43% release of copper after 2.5 hours in sodium citrate pH 7.4. The copper gluconate minitablets coated with Opadry® (3% W.G.) and Eudragit® FS 30 D (6% W.G.) demonstrated 61.02% release of copper after 2 hours in sodium citrate pH 7.4 and 88.48% release of copper after 2.5 hours in sodium citrate pH 7.4 (Tables 20, 21 and FIG. 7).

Further dissolution studies are performed with copper gluconate minitablets coated with 3% Opadry®, 8% Acryl-EZE®, and 2% Eudragit® RL. Copper in the minitablets is intended to be released in small intestine for patients with and without treatment of proton pump inhibitors (PPI)s having a neutral or acidic stomach pH, respectively. Copper release is expected to be slightly earlier in the presence of treatment with PPIs and relatively slower for an acidic stomach. 2% Eudragit® RL coating gives an additional 2-3 hour delay of copper release beyond the 2 hour protection from acid provided by Acryl-EZE® alone. The actual dissolution profile of copper gluconate with 8% Acryl-EZE® and 2% Eudragit® RL should fall into the region between hypothetical curve #1 and #2 (FIGS. 8-11). Dissolution tests are also performed on copper gluconate minitablets coated with 3% Opadry®, 4% Eudragit® FS, and 2% Eudragit® RL. Copper in the minitablets is intended to be released in ileum/colon for patients with and without treatment of PPIs (neutral or acidic stomach pH, respectively). The 2% Eudragit® RL coating gives additional 2-3 hour delay on copper release beyond the 2 hour protection from acid provided by Eudragit® FS alone. The actual dissolution profile of copper gluconate with 4% Eudragit® FS and 2% Eudragit® RL should fall into the region between hypothetical curve #1 and #2 (FIGS. 8-11).
