However, magnesium sulfate, the most abundant intracellular cation, is essential in vascular endothelial functionality due to its anti-inflammatory and vasodilatory effects. Therefore, the present study aims to assess these treatment regimens and how they could potentially provide some additional benefits in PH therapy. Fourteen days after chronic-hypoxia PH was induced, rosuvastatin, sildenafil and magnesium sulfate were administered for an additional fourteen days to male Wistar rats. The Fulton Index, right ventricle (RV) anterior wall thickness, RV internal diameter and pulmonary arterial (PA) acceleration time\/ejection time were evaluated, and another four biochemical parameters were calculated: brain natriuretic peptide, vascular endothelial growth factor, nitric oxide metabolites and endothelin 1. The present study demonstrates that sildenafil and rosuvastatin have modest effects in reducing RV hypertrophy and RV systolic pressure. The drug combination of sildenafil + rosuvastatin + magnesium sulfate recorded statistically very highly significant results on all parameters; through their positive synergistic effects on vascular endothelial function, oxidative stress and pathological RV remodeling, they attenuated PH in the chronic hypoxia pulmonary hypertension (CHPH) rat model.<\/jats:p>","DOI":"10.3390\/life14091193","type":"journal-article","created":{"date-parts":[[2024,9,23]],"date-time":"2024-09-23T03:36:38Z","timestamp":1727062598000},"page":"1193","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Magnesium Sulfate, Rosuvastatin, Sildenafil and Their Combination in Chronic Hypoxia-Induced Pulmonary Hypertension in Male Rats"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6875-3031","authenticated-orcid":false,"given":"Silvana-Elena","family":"Hojda","sequence":"first","affiliation":[{"name":"Department of Physiology, \u201cIuliu Hatieganu\u201d University of Medicine and Pharmacy, Number 1\u20133, Clinicilor Street, RO-400023 Cluj-Napoca, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4991-0032","authenticated-orcid":false,"given":"Irina Camelia","family":"Chis","sequence":"additional","affiliation":[{"name":"Department of Physiology, \u201cIuliu Hatieganu\u201d University of Medicine and Pharmacy, Number 1\u20133, Clinicilor Street, RO-400023 Cluj-Napoca, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0046-0803","authenticated-orcid":false,"given":"Simona","family":"Clichici","sequence":"additional","affiliation":[{"name":"Department of Physiology, \u201cIuliu Hatieganu\u201d University of Medicine and Pharmacy, Number 1\u20133, Clinicilor Street, RO-400023 Cluj-Napoca, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1801913","DOI":"10.1183\/13993003.01913-2018","article-title":"Haemodynamic Definitions and Updated Clinical Classification of Pulmonary Hypertension","volume":"53","author":"Simonneau","year":"2019","journal-title":"Eur.
