LC-MS/MS method for co-estimation of doxorubicin and piperine: formulation development and pharmacokinetic studies.
Article in Bioanalysis, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionOral metronomic chemotherapy employs a low-dose combination of chemotherapeutics administered regularly to minimize toxicity while enhancing anticancer efficacy. The clinical utility of Doxorubicin (DOX) is limited due to severe cardiotoxicity. Interestingly, Piperine (PIP) has been explored to mitigate DOX-induced toxicity while enhancing its therapeutic efficacy. Solid lipid nanoparticles (SLNs) offer an efficient drug delivery approach to improve oral bioavailability and controlled release of DOX and PIP. AREAS COVERED: LC-MS/MS method was developed and validated per US-FDA bioanalytical guidelines to quantify DOX and PIP in plasma simultaneously. SLNs were developed and optimized using design expert software and exhibited particle size of 151.56 ± 0.32 nm, polydispersity index (PDI) of 0.172 ± 0.02, and surface charge of -22.83 ± 0.66 mV. Pharmacokinetic evaluation in female Sprague-Dawley rats showed enhanced AUC₀-∞ for DOX (31911.78 ± 226.92 ng/mL) and PIP (7377.66 ± 655.78 ng/mL), indicating improved systemic exposure. EXPERT OPINION: The findings highlight the potential of SLN-based co-delivery of DOX and PIP for oral metronomic chemotherapy. The validated LC-MS/MS method ensures precise pharmacokinetic assessment, which is crucial for future clinical translation. This study provides a promising strategy for enhancing oral chemotherapy efficacy.
