Newer drugs, such as bempedoic acid, inclisiran, alirocumab, and evolocumab have recently been introduced for dyslipidemia. This systematic review aims to perform a comparative analysis of these drugs' low-density lipoprotein cholesterol (LDL-C)-lowering activities. The PubMed database was utilized to search for randomized controlled trials. Articles were screened and selected based on specific inclusion and exclusion criteria. The primary outcome of this review is to compare the percentage reduction of LDL-C and apolipoprotein-B, along with the number of reported serious adverse events (SAEs) in trials specific to each drug. A total of 14 studies were included, four for bempedoic acid and alirocumab and three for evolocumab and inclisiran. The maximum percentage reduction in LDL-C and apolipoprotein-B from baseline to 12 weeks was observed with alirocumab, administered at 150 mg subcutaneously twice weekly for 12 weeks, achieving reductions of 72.4% and 57.9%, respectively. Lesser reductions were observed with bempedoic acid, administered at 180 mg once daily orally for 12 weeks. The highest number of SAEs were reported with bempedoic acid (216, 10%) and inclisiran (181, 11%; 175, 11%). This systematic review showed that alirocumab achieved the greatest reductions in LDL-C and apolipoprotein-B and a better safety profile. Newer LDL-C-lowering drugs show promise in improving lipid profiles, patient compliance, and safety. However, these findings are not conclusive, as other factors also influence treatment choice.
