What is the potency of Pitavastatin (Pitavastatin) compared to other statins (HMG-CoA reductase inhibitors)?

From the Guidelines

Pitavastatin is a potent statin with high efficacy at low doses, achieving 30-40% LDL reduction at 1-2 mg daily and up to 45-50% reduction at 4 mg daily, making it a suitable option for patients requiring significant lipid lowering with minimal side effects. In terms of potency, pitavastatin 4 mg is approximately equivalent to atorvastatin 20 mg and rosuvastatin 10 mg, and is significantly more potent than simvastatin, pravastatin, and fluvastatin 1. The typical dosing range for pitavastatin is 1-4 mg once daily, with 1 mg being appropriate for initial therapy in most patients, while 2-4 mg may be needed for patients requiring greater LDL reduction 1. Pitavastatin has several advantages, including minimal metabolism through CYP450 enzymes, resulting in fewer drug interactions than other statins, and a long half-life allowing for once-daily dosing 1. Some key points to consider when prescribing pitavastatin include:

• Dose adjustments are necessary for patients with severe renal impairment
• Pitavastatin demonstrates favorable effects on HDL cholesterol and triglycerides
• Pitavastatin's high potency at low doses makes it particularly useful for patients who need significant lipid lowering but are prone to statin-related side effects or drug interactions
• The use of pitavastatin should be individualized based on the patient's specific needs and medical history, as recommended by the international lipid expert panel (ILEP) 1.

From the FDA Drug Label

For the percent change from baseline to endpoint in LDL-C, pitavastatin was non-inferior to atorvastatin for the two pairwise comparisons: Pitavastatin 2 mg vs. atorvastatin 10 mg and pitavastatin 4 mg vs. atorvastatin 20 mg. Mean treatment differences (95% CI) were 0% (-3%, 3%) and 1% (-2%, 4%), respectively. Pitavastatin was non-inferior to simvastatin for the two pairwise comparisons: Pitavastatin 2 mg vs. simvastatin 20 mg and pitavastatin 4 mg vs. simvastatin 40 mg. Mean treatment differences (95% CI) were 4% (1%, 7%) and 1% (-2%, 4%), respectively. Pitavastatin significantly reduced LDL-C compared to pravastatin as demonstrated by the following pairwise dose comparisons: Pitavastatin 1 mg vs. pravastatin 10 mg, pitavastatin 2 mg vs. pravastatin 20 mg and pitavastatin 4 mg vs. pravastatin 40 mg. Mean treatment differences (95% CI) were 9% (6%, 12%), 10% (7%, 13%) and 10% (7%, 13%), respectively.

The potency of pitavastatin compared to other statins is as follows:

• Pitavastatin 2 mg is non-inferior to atorvastatin 10 mg with a mean treatment difference of 0% (-3%, 3%) in LDL-C reduction.
• Pitavastatin 4 mg is non-inferior to atorvastatin 20 mg with a mean treatment difference of 1% (-2%, 4%) in LDL-C reduction.
• Pitavastatin 2 mg is non-inferior to simvastatin 20 mg with a mean treatment difference of 4% (1%, 7%) in LDL-C reduction.
• Pitavastatin 4 mg is non-inferior to simvastatin 40 mg with a mean treatment difference of 1% (-2%, 4%) in LDL-C reduction.
• Pitavastatin is more potent than pravastatin with mean treatment differences of 9% (6%, 12%), 10% (7%, 13%), and 10% (7%, 13%) in LDL-C reduction for the respective dose comparisons 2.

From the Research

Potency of Pitavastatin Compared to Other Statins

• Pitavastatin is a highly potent 3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) reductase inhibitor, with a potent cholesterol-lowering action 3, 4.
• Compared to other statins, pitavastatin has been shown to be more potent than atorvastatin, simvastatin, and pravastatin in lowering LDL cholesterol levels 3, 5, 6.
• Pitavastatin has been found to reduce LDL cholesterol levels by 33.3% to 54.7%, total cholesterol by 23.3% to 39.0%, and triglycerides by 13.0% to 28.1% 5.
• The potency of pitavastatin compared to other statins is as follows:
  • 6-fold more potent than atorvastatin 5
  • 1.7-fold more potent than rosuvastatin 5
  • 77-fold more potent than fluvastatin 5
  • 3.3-fold less potent than cerivastatin 5

Efficacy of Pitavastatin in Different Patient Populations

• Pitavastatin has been shown to be effective in reducing LDL cholesterol levels in patients with primary hypercholesterolemia and combined (mixed) dyslipidemia, including those with type 2 diabetes or ≥2 cardiovascular risk factors 3, 6.
• Pitavastatin has also been found to be effective in Asian patients, with sustained LDL-C-lowering efficacy over up to 60 weeks' therapy 6.
• In patients with hyperlipidemia type IIa, pitavastatin has been shown to be less effective than atorvastatin in reducing triglyceride levels, but in patients with hyperlipidemia type IIb, there was no significant difference between the two treatments 7.

Safety and Tolerability of Pitavastatin

• Pitavastatin has been found to be generally well tolerated, with the most common treatment-related adverse events being musculoskeletal or gastrointestinal in nature 3, 6.
• Pitavastatin has not been shown to adversely affect glucose metabolism parameters, such as fasting blood glucose, fasting plasma glucose, fasting plasma insulin, and glycated hemoglobin 3, 6.
