Prescription system to calculate precise doses of Chinese herbal medicine to avoid toxic effects.

Background and objectives: Traditional Chinese Medicine (TCM) is a therapeutic system which has been practiced for thousands of years. Although for much of its history the decoction of medicinal herbs was the most common method of consuming the herbal treatments, TCM prescriptions are now primarily prepared using concentrated Chinese herbal extracts (CCHE) in powder or granular form. However, determining the precise dose of each single Chinese herbal constituent within a prescription creates a challenge in clinical practice due to the potential risk of toxicity. To alleviate this, we invented the Chinese Intelligence Prescription System (CIPS) to calculate the exact dose of each single herb within an individual prescription. Methods: In this study, we applied CIPS in a real-world setting to analyze clinical prescriptions collected and prepared at the TCM Pharmacy of China Medical University Hospital (CMUH). Results: Our investigation revealed that 3% of all prescriptions filled in a 1-month period contained inexact dosages, suggesting that more than 170,000 prescriptions filled in Taiwan in a given month may contain potentially toxic components. We further analyzed the data to determine the excess dosages and outline the possible associated side effects. Conclusions: In conclusion, CIPS offers TCM practitioners the ability to prepare exact Chinese herbal medicine (CHM) prescriptions in order to avoid toxic effects, thereby ensuring patient safety.

Chinese Intelligence Prescription System improves prescription accuracy while decreasing labor and drug costs.

BACKGROUND AND AIM: The traditional method of taking Chinese Medicine involves creating a decoction by cooking medicinal Chinese herbs. However, this method has become less popular, being replaced by the more convenient method of consuming concentrated Chinese herbal extracts, which creates challenges related to the complexity of stacking multiple formulas. METHODS: We developed the Chinese Intelligence Prescription System (CIPS) to simplify the prescription process. In this study, we used data from our institutions pharmacy to calculate the number of reductions, average dispensing time, and resulting cost savings. RESULTS: The mean number of prescriptions was reduced from 8.19 ± 3.65 to 7.37 ± 3.34 ([Formula: see text]). The reduction in the number of prescriptions directly resulted in decreased dispensing time, reducing it from 1.79 ± 0.25 to 1.63 ± 0.66 min ([Formula: see text]). The reduced dispensing time totaled 3.75 h per month per pharmacist, equivalent to an annual labor cost savings of $15,488 NTD per pharmacist. In addition, drug loss was reduced during the prescription process, with a mean savings of $4,517 NTD per year. The combined savings adds up to a not insignificant $20,005 NTD per year per pharmacist. When taking all TCM clinics/hospitals in Taiwan into account, the total annual savings would be $77 million NTD. CONCLUSION: CIPS assists clinicians and pharmacists to formulate precise prescriptions in a clinical setting to simplify the dispensing process while reducing medical resource waste and labor costs.

Characterization of genipin-crosslinked gelatin/hyaluronic acid-based hydrogel membranes and loaded with hinokitiol: In vitro evaluation of antibacterial activity and biocompatibility.

Hydrogel membranes are often used as physical barriers in oral tissue reconstruction and facial surgery to isolate connective and epithelial tissues and form a closed space for undisturbed bone healing. In this study, gelatin and hyaluronic acid were crosslinked with genipin and loaded with a hinokitiol additive as a bacteriostatic agent for potential applications as regeneration membranes. This bifunctional membrane had biocompatibility and antibacterial activities on each membrane side for proper biodegradation. Different membrane groups of gelatin/hyaluronic acid were obtained via a solution casting technique and were genipin crosslinked. The membrane groups were further loaded with adequate hinokitiol at a loading concentration of up to 0.16 g/L (hinokitiol to phosphate buffered saline). Fourier transform infrared spectroscopy showed that gelatin and hyaluronic acid were crosslinked with genipin through cross-linking amide bond (CONH) formation with a cross-linking degree of over 84%. The groups with hinokitiol showed substantial antibacterial activity. Meanwhile, the addition of hinokitiol on hydrogel membranes did not significantly affect the tensile strength. However, it decreased the solubility of the membranes by slowing down the relaxation and degradation of their molecular junctions as hinokitiol is a hydrophobic compound with low permeability. Consequently, the degradation of hydrogel membranes with hinokitiol was delayed. In vitro cytocompatibility indicated that the cell viability of the groups with hinokitiol increased with incubation time, demonstrating that cell viability and proliferation were not affected by cell culture testing.
