Safety and Tolerability of PCSK9 Inhibitors: Current Insights.

The current era of preventive cardiology continues to emphasize on low-density lipoprotein cholesterol (LDL-C) reduction to alleviate the burden of atherosclerotic cardiovascular disease (ASCVD). In this regard, the pharmacological inhibition of proprotein convertase subtilisin/kexin type 9 (PCSK9) enzyme via monoclonal antibodies has emerged as a novel lipid-lowering therapy, leading to a marked reduction in circulating LDL-C levels and subsequent improvement of cardiovascular outcomes. As these agents are increasingly used in current clinical practice, mounting scientific and clinical evidence supports that PCSK9 inhibitors offer an excellent safety and tolerability profile with a low incidence of adverse events.

Inclisiran for the Treatment of Cardiovascular Disease: A Short Review on the Emerging Data and Therapeutic Potential.

Proprotein convertase subtilisin kexin 9 (PCSK-9)-targeting therapy has arisen as a new line for the treatment of hyperlipidemia. Inclisiran is a double-stranded small RNA molecule that works by blocking the transcription of PCSK-9, leading to a reduction of PCSK9 levels in the hepatocytes, resulting in an increased expression of low-density lipoprotein (LDL) receptors in the hepatocyte membrane and, as a consequence, it reduces the circulating levels of LDL cholesterol (LDL-C). Compared to the other LDL-C-lowering medications, such as statins, ezetimibe and PCSK-9 inhibitors, inclisiran proposes an infrequent dosing of twice a year, while simultaneously providing a significant reduction of LDL-C.
