NCT06808646
The goal of this clinical study was to determine the effect of the test drug ceftobiprole (a drug approved for the treatment of bacterial infections) on the elimination of pitavastatin (a drug approved for the treatment of increased levels of cholesterol in blood) from the body. This interaction was investigated by pharmacokinetic (PK) assessments. The clinical study also investigated the safety of ceftobiprole and how well ceftobiprole was tolerated by healthy subjects when it was administered in combination with pitavastatin.
NCT07426042
Purpose: The purpose of this study is to understand how dexamethasone affects the activity of drug-metabolizing enzymes in the body and how this may influence interactions with other medicines, such as voriconazole. Background: Many medicines are broken down in the body by enzymes called cytochrome P450 (CYP) enzymes. Differences in CYP enzyme activity between individuals can lead to variability in drug response and drug-drug interactions. Dexamethasone is known to affect CYP enzyme activity, and voriconazole is a medication that is metabolized by these enzymes. Participants: This study will include a total of 12 healthy adult male volunteers. Participants will be grouped based on their metabolic status, including 6 normal metabolizers (NM) and 6 poor metabolizers (PM). Interventions: Participants will receive a combination of probe drugs known as a CYP probe cocktail to assess baseline CYP enzyme activity. Dexamethasone will be administered, and the CYP probe cocktail will be given again to evaluate changes in enzyme activity. Voriconazole will be used to assess the potential for drug-drug interactions related to changes in CYP enzyme activity. Blood samples will be collected during the study. Outcome Measures: The main outcomes of this study are changes in blood concentrations of the probe drugs, which reflect changes in CYP enzyme activity, and comparisons of these changes between normal metabolizers and poor metabolizers. Hypothesis: The study hypothesizes that dexamethasone alters CYP enzyme activity and that the magnitude of this effect differs between normal metabolizers and poor metabolizers, potentially affecting the metabolism of drugs such as voriconazole.
NCT07330531

NCT07017335
This is a Phase 1, open-label, randomized, crossover clinical trial designed to evaluate the potential drug-drug interaction (DDI) between R1\_PBK\_M2301 (levodropropizine 60 mg) and R2\_PBK\_M2301 (Pelargonium sidoides ethanol extract 11%) in healthy adult volunteers. The study aims to assess the pharmacokinetics of each investigational drug when administered alone and in combination. Approximately \[insert number\] healthy subjects will participate in two treatment periods with appropriate washout intervals. Safety, tolerability, and pharmacokinetic parameters will be evaluated to support future combination development.

Open-label prospective intensive pharmacokinetic study of dihydroartemisinin-piperaquine (DP) in HIV-infected children on efavirenz (EFV)-, lopinavir/ritonavir (LPV/r)-, or dolutegravir (DTG)-based antiretroviral therapy (ART) and HIV-uninfected children not on ART. All children will be malaria-uninfected at the time of enrollment.
NCT06682325
The goal of this observational study is to enhance the ability to forecast kidney failure in liver transplant patients in the ICU under multidrug treatment by developing a computer platform that integrates mathematical models of drug interactions, proteomics, and clinical data. The main outcomes it aims to develop are: 1. Design the multidrug web computing platform with available information on drug pair interactions (DDIs). 2. Integrate the proteomic and clinical data of liver transplant patients into the IT platform. 3. Implement the multidrug web platform to predict the clinical evolution of liver transplant patients.
NCT05073627
Worldwide there is an increase in antibiotic resistance which may have fatal long-term consequences. This is due to extensive use and sometimes misuse of antibiotics in the treatment of harmless infections. The primary aim of this study is to investigate if treatment with dicloxacillin can lead to drug-drug interactions through induction of the efflux transporter P-glycoprotein (P-gp). In this study it will also be investigated whether dicloxacillin induces its own metabolism. The hypothesis is based on a previous in vivo study showing that rifampicin induces the intestinal P-gp transporter, through activation of the pregnane X receptor (PXR). Dicloxacillin also activates the PXR receptor in vitro, which could result in an induction of P-gp in vivo. Trial subjects will ingest dicloxacillin for 30 days and at day 10 and 28 ingest dabigatran etexilate to determine if the P-gp transporter has been induced. Plasma and urine will be drawn over 32 hours to determine the concentration of dabigatran. Change in dicloxacillin concentration will also be measured at day 9 and 27 to establish if dicloxacillin induces its own metabolism.

NCT04899960
Drug-related problems in newborn babies have been reported with a rate of 4-30%. It is estimated that the higher rates of these problems in hospitalized children under the age of two are related to the variety of drugs used and the differences in the age, weight and diagnosis of the patients. In this context, with the clinical parameters and demographic data obtained in the first 24 hours of the patients hospitalized in the neonatal intensive care unit, machine learning algorithms are used to predict the risks that may arise from possible drug-related problems (prescribing and administration errors, side effects and drug-drug interactions) that may occur during hospitalization. The algorithm, which will be created by modeling with a high number of big data pool, is planned to be transformed into a clinical decision support system software that can be used easily in clinical practice with online and mobile applications. By processing the data of the patients to be included in the model, it is aimed to prevent and manage drug-related problems before they occur, as well as to provide cost-effective medşcation treatment to patients hospitalized in the neonatal intensive care unit, together with a reduction in the risk of drug-related mortality and morbidity.
NCT04459585
The purpose of this study is to investigate the one-way drug-drug interaction potential of quizartinib on dabigatran etexilate in healthy adult participants.
NCT04621253
This clinical phase I trial had 3 arms: inhibition by fluconazole, inhibition by ciprofloxacin and placebo. Subjects were treated for 3 days prior to the study day. The intervention was a single dose of 1 gram metamizole. We took blood samples at set time points and analysed the concentration of the main metabolites of metamizole at each time point in plasma.
NCT03723395
This study is being done to look at how tucatinib could affect the way other drugs work. This study will look at healthy volunteers and how tucatinib affects their liver enzymes. Liver enzymes can change how drugs work in the body. There are 5 parts to this study. Parts A and C are looking at how the body breaks down tucatinib when there are lower levels of certain liver enzymes. Part B is looking at how the body breaks down tucatinib when there are high levels of certain liver and stomach enzymes. Parts D and E are looking at how tucatinib could change the levels of some liver and stomach enzymes in the body. This will help us know more about how tucatinib should be given to patients.
NCT03990129
Investigators conducted a single center, two-phased, open, controlled pharmacokinetic study to investigate the drug-drug interaction potential of metamizole. For this reason, healthy male volunteers were screened. Enrolled participants were phenotyped on day 1 using the Basel Cocktail (phenotyping cocktail containing specific substrates for CYP1A2, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP3A4). After, they received metamizole treatment for 8 days (3 grams per day). On the 8th day (day 9), they were phenotyped again with the Basel Cocktail and the respective phenotypes (d1 vs. d9) were compared.
NCT03581994
The DECART study will determine if primary care physicians, including internists and family physicians, are able to identify and address drug-drug interactions among simulated patients and whether those physicians, when given access to Aegis Drug-Drug Interaction test results, improve patient management, take steps to reduce DDI risk, and optimize unnecessary resource utilization.
NCT02227173
