Lowering low-density lipoprotein cholesterol (LDL-C) levels is a primary strategy to reduce ASCVD risk. Although statin therapy remains the initial therapy of choice to reduce LDL-C and ASCVD risk, statin intolerance and suboptimal LDL-C lowering response prompts the need for additional non-statin therapies. Ezetimibe and bempedoic acid are reasonable options but they modestly reduce LDL-C levels (15% to 25%). Therapies directed at the proprotein convertase subtilisin/kexin type 9 (PCSK9) enzyme, however, reduce LDL-C levels by 50%-60% when added to background statin therapy. PCSK9 is an enzyme synthesized by the liver that facilitates the degradation of LDL receptors and prevents their recycling to the hepatocyte surface to remove LDL-C from circulation. Approaches to inhibit this effect have centered on monoclonal antibodies (mAbs) (alirocumab, evolocumab) targeting PCSK9 functionality and small interfering RNA (siRNA) therapies (inclisiran) targeting the hepatic synthesis of PCSK9. Randomized controlled trials have demonstrated beneficial cardiovascular outcomes of PCSK9 mAbs, but such evidence is not yet available for inclisiran. Current clinical practice guidelines generally recommend PCSK9-directed therapies for higher-risk patients with established ASCVD and those with familial hypercholesterolemia. This approach is, in part, due to their cost and uncertain economic value, but also because these therapies require subcutaneous administration, which is not preferred by some patients. Oral therapies targeting PCSK9 are, however, in development. This scoping review covers the development of current and emerging PCSK9-directed therapies, their efficacy, safety, and role in clinical practice.</p>","PeriodicalId":20013,"journal":{"name":"Pharmacotherapy","volume":" ","pages":"54-65"},"PeriodicalIF":2.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11755694/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142829728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Personalized medicine is a tool that can be used to optimize diagnosis and treatments of many diseases. In this review, we will focus on three areas related to the genetics of pediatric obesity: (i) genetic causes predisposing to pediatric obesity, (ii) pharmacogenomics that may predict weight gain associated with pharmacotherapy, and (iii) pharmacogenomics of anti-obesity pharmacotherapy. This narrative review evaluates genetic cause of pediatric obesity and how genetic findings can be used to optimize pharmacotherapy to minimize weight gain and optimize obesity treatment in pediatric patients. Pediatric obesity has many genetic causes including genomic obesity syndromes and monogenic obesity disorders. Several genetic etiologies of obesity have current or emerging targeted genetic therapies. Pharmacogenomic (PGx) targets associated with pharmacotherapy-induced weight gain have been identified for antipsychotic, antiepileptic, antidepressant therapies, and steroids, yet to date no clinical guidelines exist for application use of PGx to tailor pharmacotherapy to avoid weight gain. As legislation evolves for genetic testing coverage and technology advances, this will decrease cost and expand access to genetic testing. This will result in identification of potential genetic causes of obesity and genes that predispose to pharmacotherapy-induced weight gain. Advances in precision medicine can ultimately lead to development of clinical practice guidelines on how to apply genetic findings to optimize pharmacotherapy to treat genetic targets of obesity and avoid weight gain as an adverse event associated with pharmacotherapy.</p>","PeriodicalId":20013,"journal":{"name":"Pharmacotherapy","volume":" ","pages":"939-947"},"PeriodicalIF":2.9,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11687202/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142644383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aztreonam-avibactam (ATM-AVI) is a promising new combination therapy designed to combat multidrug-resistant (MDR) gram-negative bacteria, including those producing metallo-β-lactamases (MBLs). Aztreonam, a monobactam antibiotic, is resistant to hydrolysis by MBLs but can be degraded by other β-lactamases. Avibactam, a novel non-β-lactam β-lactamase inhibitor, effectively neutralizes extended-spectrum β-lactamases (ESBLs) and AmpC β-lactamases, restoring aztreonam's efficacy against resistant pathogens. This review covers the chemistry, mechanisms of action, spectrum of activity, pharmacokinetics, pharmacodynamics, and clinical efficacy of ATM-AVI. ATM-AVI combination has shown efficacy against a wide range of resistant Enterobacterales and other gram-negative bacteria in both in vitro and clinical studies. Pharmacokinetic and pharmacodynamic analyses demonstrate that ATM-AVI maintains effective drug concentrations in the body, with dose adjustments recommended for patients with renal impairment. Clinical trials, including the REVISIT and ASSEMBLE studies, have demonstrated the safety and efficacy of ATM-AVI in treating complicated intra-abdominal infections (cIAI), urinary tract infections (UTIs), and hospital-acquired pneumonia (HAP) caused by MDR gram-negative pathogens. The European Medicines Agency (EMA) has approved ATM-AVI for these indications, and further research is ongoing to optimize dosing regimens and expand its clinical use.
