Expert Opin Pharmacother 2025; 26:743-753. [PMID: 40091694 DOI: 10.1080/14656566.2025.2480764] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2024] [Accepted: 03/13/2025] [Indexed: 03/19/2025]
Abstract
INTRODUCTION Pulmonary hypertension is a life-threatening condition characterized by elevated mean pulmonary arterial pressure and vascular resistance. Significant advances in diagnosis and treatment have been achieved over the 20th and 21st centuries, yet challenges remain in improving long-term outcomes. AREAS COVERED This review discusses the historical milestones in understanding and pharmacotherapy of the pulmonary arterial hypertension (PAH). A comprehensive literature search was conducted to explore the earliest reports of each approved medication for pulmonary hypertension, along with historical papers detailing the pathophysiological and diagnostic development. Additionally, the search aimed to identify novel therapeutic strategies, including repositioned drugs and emerging targets. EXPERT OPINION While current therapies, such as prostacyclin analogs and PDE5 inhibitors, improve functional capacity and hemodynamics, they face limitations, including costs, administration, and a predominantly vasodilatory approach. Additionally, the limitations of current clinical trial designs for rare diseases like pulmonary arterial hypertension hinder the evaluation of potentially effective drugs. These challenges underscore the urgent need for translational research to optimize trial methodologies, accelerating the development of new therapies. Innovative approaches, such as drug repositioning and the exploration of novel molecular targets, are critical to overcoming these barriers and ensuring timely, effective, and affordable treatment options for patients with PAH.

Abstract
Selexipag is an oral selective prostacyclin receptor agonist approved for the treatment of pulmonary arterial hypertension (PAH) in adults. To date, no treatment targeting the prostacyclin pathway is approved for pediatric patients. Our goal is to identify a pediatric dose regimen that results in comparable exposures to selexipag and its active metabolite JNJ-68006861 as those shown to be efficacious in adult PAH patients. Extrapolation from the population pharmacokinetic (PK) model developed in adults (GRIPHON study; NCT01106014) resulted in the definition of three different pediatric body weight groups (≥9 to <25 kg, ≥25 to <50 kg, and ≥50 kg) with corresponding starting doses (100, 150, and 200 μg twice daily) and maximum allowed doses (800, 1200, and 1600 μg twice daily). The proposed pediatric dose regimen was subsequently tested in a clinical study (NCT03492177), including 63 pediatric PAH patients ≥2 to <18 years of age and a body weight range of 9.9-93.5 kg. The body weight-adjusted dose regimen for selexipag resulted in comparable systemic exposures to selexipag and its active metabolite in pediatric patients as previously observed in adult PAH patients. Updating the adult selexipag population PK model provided overall consistent parameters and confirmed that the PK characteristics of selexipag and its active metabolite were comparable between pediatric and adult patients. The presented selexipag dose regimen for pediatric PAH patients is considered appropriate for continuing the clinical evaluation of the safety and efficacy of selexipag in pediatric patients ≥2 years of age.

Abstract
Objective: To evaluate the potential for drug interactions with therapies for pulmonary arterial hypertension (PAH). Treatments include calcium channel blockers, phosphodiesterase type 5 inhibitors, endothelin receptor antagonists, guanylate cyclase stimulators, prostacyclin analogues, and prostacyclin receptor agonists. Data Sources: A systemic literature search (January 1980-December 2021) was performed using PubMed and EBSCO to locate relevant articles. The mesh terms used included each specific medication available as well as "drug interactions." DAILYMED was used for product-specific drug interactions. Study Selection and Data Extraction: The search was conducted to identify drug interactions with PAH treatments. The search was limited to those articles studying human applications with PAH treatments and publications using the English language. Case reports, clinical trials, review articles, treatment guidelines, and package labeling were selected for inclusion. Data Synthesis: Primary literature and package labeling indicate that PAH treatments are subject to pharmacokinetic and pharmacodynamic interactions. The management of PAH is rapidly evolving. As more and more evidence becomes available for the use of combination therapy in PAH, the increasing use of combination therapy increases the risk of drug-drug interactions. Pulmonary arterial hypertension is also associated with other comorbidities that require concomitant pharmacotherapy. Conclusion: The available literature indicates that PAH therapies are associated with clinically significant drug interactions and the potential for subsequent adverse reactions. Clinicians in all practice settings should be mindful that increased awareness of drug interactions with PAH therapy will ensure optimal management and patient safety.

[PMID: 34860644 PMCID: PMC8648015 DOI: 10.1080/13880209.2021.2005636] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/09/2021] [Revised: 09/09/2021] [Accepted: 11/08/2021] [Indexed: 06/13/2023]
Abstract
CONTEXT As an inhibitor cytochrome P450 family 2 subfamily C polypeptide 8 (CYP2C8), quercetin is a naturally occurring flavonoid with its glycosides consumed at least 100 mg per day in food. However, it is still unknown whether quercetin and selexipag interact. OBJECTIVE The study investigated the effect of quercetin on the pharmacokinetics of selexipag and ACT-333679 in beagles. MATERIALS AND METHODS The ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was used to investigate the pharmacokinetics of orally administered selexipag (2 mg/kg) with and without quercetin (2 mg/kg/day for 7 days) pre-treatment in beagles. The effect of quercetin on the pharmacokinetics of selexipag and its potential mechanism was studied through the pharmacokinetic parameters. RESULTS The assay method was validated for selexipag and ACT-333679, and the lower limit of quantification for both was 1 ng/mL. The recovery and the matrix effect of selexipag were 84.5-91.58% and 94.98-99.67%, while for ACT-333679 were 81.21-93.90% and 93.17-99.23%. The UPLC-MS/MS method was sensitive, accurate and precise, and had been applied to the herb-drug interaction study of quercetin with selexipag and ACT-333679. Treatment with quercetin led to an increased in Cmax and AUC0-t of selexipag by about 43.08% and 26.92%, respectively. While the ACT-333679 was about 11.11% and 18.87%, respectively. DISCUSSION AND CONCLUSION The study indicated that quercetin could inhibit the metabolism of selexipag and ACT-333679 when co-administration. Therefore, the clinical dose of selexipag should be used with caution when co-administered with foods high in quercetin.

Abstract
The management of pulmonary arterial hypertension (PAH) has become more complex in recent years because of increased pharmacotherapy options and longer patient survival with increasing numbers of comorbidities. As such, more opportunities exist for drug-drug interactions between PAH-targeted medications and medications potentially used to treat comorbid conditions. In this review, we provide an overview of pharmaceutical metabolism by cytochrome P450 and discuss important drug-drug interactions for the 14 Food and Drug Administration-approved medications for PAH in the nitric oxide (NO), endothelin, and prostacyclin pathways. Among the targets in the NO pathway (sildenafil, tadalafil, and riociguat), important interactions with nitrates, protease inhibitors, and other phosphodiesterase inhibitors can cause profound hypotension. In the endothelin pathway, bosentan is associated with more drug interactions via CYP3A4 inhibition; macitentan and ambrisentan have fewer interactions of note. Although the parenteral therapies in the prostacyclin pathway bypass significant liver metabolism and avoid drug interactions, selexipag and oral treprostinil may exhibit interactions with CYP2C8 inhibitors such as gemfibrozil and clopidogrel, which can raise drug levels. Finally, we provide a framework for identifying potential drug-drug interactions and avoiding errors.

Physiologically Based Pharmacokinetic (PBPK) Modeling of Clopidogrel and Its Four Relevant Metabolites for CYP2B6, CYP2C8, CYP2C19, and CYP3A4 Drug–Drug–Gene Interaction Predictions. Pharmaceutics 2022; 14:pharmaceutics14050915. [PMID: 35631502 PMCID: PMC9145019 DOI: 10.3390/pharmaceutics14050915] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Revised: 04/19/2022] [Accepted: 04/20/2022] [Indexed: 11/23/2022] Open
Abstract
The antiplatelet agent clopidogrel is listed by the FDA as a strong clinical index inhibitor of cytochrome P450 (CYP) 2C8 and weak clinical inhibitor of CYP2B6. Moreover, clopidogrel is a substrate of—among others—CYP2C19 and CYP3A4. This work presents the development of a whole-body physiologically based pharmacokinetic (PBPK) model of clopidogrel including the relevant metabolites, clopidogrel carboxylic acid, clopidogrel acyl glucuronide, 2-oxo-clopidogrel, and the active thiol metabolite, with subsequent application for drug–gene interaction (DGI) and drug–drug interaction (DDI) predictions. Model building was performed in PK-Sim® using 66 plasma concentration-time profiles of clopidogrel and its metabolites. The comprehensive parent-metabolite model covers biotransformation via carboxylesterase (CES) 1, CES2, CYP2C19, CYP3A4, and uridine 5′-diphospho-glucuronosyltransferase 2B7. Moreover, CYP2C19 was incorporated for normal, intermediate, and poor metabolizer phenotypes. Good predictive performance of the model was demonstrated for the DGI involving CYP2C19, with 17/19 predicted DGI AUClast and 19/19 predicted DGI Cmax ratios within 2-fold of their observed values. Furthermore, DDIs involving bupropion, omeprazole, montelukast, pioglitazone, repaglinide, and rifampicin showed 13/13 predicted DDI AUClast and 13/13 predicted DDI Cmax ratios within 2-fold of their observed ratios. After publication, the model will be made publicly accessible in the Open Systems Pharmacology repository.

Abstract
Multimorbidity, polypharmacotherapy and drug interactions are increasingly common in the ageing population. Many drug-drug interactions (DDIs) are caused by perpetrator drugs inhibiting or inducing cytochrome P450 (CYP) enzymes, resulting in alterations of the plasma concentrations of a victim drug. DDIs can have a major negative health impact, and in the past, unrecognized DDIs have resulted in drug withdrawals from the market. Signals to investigate DDIs may emerge from a variety of sources. Nowadays, standard methods are widely available to identify and characterize the mechanisms of CYP-mediated DDIs in vitro. Clinical pharmacokinetic studies, in turn, provide experimental data on pharmacokinetic outcomes of DDIs. Physiologically based pharmacokinetic (PBPK) modelling utilizing both in vitro and in vivo data is a powerful tool to predict different DDI scenarios. Finally, epidemiological studies can provide estimates on the health outcomes of DDIs. Thus, to fully characterize the mechanisms, clinical effects and implications of CYP-mediated DDIs, translational research approaches are required. This minireview provides an overview of translational approaches to study CYP-mediated DDIs, going beyond regulatory DDI guidelines, and an illustrative case study of how the DDI potential of clopidogrel was unveiled by combining these different methods.

Abstract
INTRODUCTION : Pulmonary arterial hypertension (PAH) is a rare pulmonary vasculopathy. This review focuses on selexipag, a prostacyclin receptor agonist validated for the treatment of PAH. AREAS COVERED We review the structure, mechanisms of action, pharmacokinetics, and pharmacodynamics of selexipag. Clinical efficacy and tolerability are discussed using the main clinical trial published for selexipag (GRIPHON) and its post-hoc analysis. EXPERT OPINION Selexipag should be added as a triple oral combination therapy in case of insufficient response to oral combination therapy with endothelin receptor antagonist and phosphodiesterase 5 inhibitor. However, selexipag should not replace parenteral prostacyclin in high-risk patients.
