Transfersome Hydrogel Containing 5-Fluorouracil and Etodolac Combination for Synergistic Oral Cancer Treatment.
Article in AAPS PharmSciTech, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Oral cancer is one of the most common malignancies with an increased rate of incidence. 5-Fluorouracil (5FU) is an effective chemotherapeutic indicated for oral cancer treatment. Etodolac (Et), a cyclooxygenase-2 inhibitor, can be used as an adjuvant agent to sensitize cancer cells to chemotherapy. The aim of this work was to prepare and characterize 5FU and Et dual drug-loaded transfersomes to treat oral cancer. Transfersomes were prepared by thin-film hydration method and characterized for the average particle size and zeta-potential using dynamic light scattering and scanning electron microscopy techniques. The prepared transfersomes were further characterized for their drug loading, entrapment efficiencies using amicon centrifuge tubes and drug release behavior using cellulose membrane. The synergistic activity of dual drug-loaded transfersomes was studied in FaDu oral cancer cells. Results showed that the average particle size, polydispersity index, and zeta potential were 91±6.4 nm, 0.28±0.03, and (-)46.9±9.5 mV, respectively, for 5FU- and Et (1:1)-loaded transfersomes. The highest encapsulation efficiency achieved was 36.9±3.8% and 79.8±6.4% for 5FU and Et (1:1), respectively. Growth inhibition studies in FaDu cells using different concentrations of 5FU and Et showed a combination index of 0.36, indicating a synergistic effect. The FaDu cell uptake of drug-loaded transfersomes was significantly (p<0.05) greater than that of free drugs. The transfersome hydrogel made of HPMC (2% w/w) showed similar flux, lag time, and permeation coefficient as that of drug-loaded transfersomes across excised porcine buccal tissue. In conclusion, 5FU and Et transfersome hydrogel can be developed for localized delivery to treat oral cancer.
