    Chemical Structure

    • Scientific Name:  (+)monocalcium bis{(3R, 5S, 6E)-7-[2-cyclopropyl-4-(4-fluorophenyl)-3-quinolyl]-3,5-dihydroxy-6-heptenoate}
    • Empirical Formula: C50H46CaF2N2O8
    • Molecular Weight: 880.98

    Mechanism of Action
    • Pitavastatin competitively inhibits HMG-CoA reductase, which is a rate-determining enzyme involved with biosynthesis of cholesterol, in a manner of competition with the substrate so that it inhibits cholesterol synthesis in the liver. As a result, the expression of LDL-receptors followed by the uptake of LDL from blood to liver is accelerated and then the plasma TC decreases. Further, the sustained inhibition of cholesterol synthesis in the liver decreases levels of very low-density lipoproteins.
    Pharmacodynamics
    • In a randomized, double-blind, placebo-controlled, 4-way parallel, active-comparator study with moxifloxacin in 174 healthy participants, pitavastatin was not associated with clinically meaningful prolongation of the QTc interval or heart rate at daily doses up to16 mg (4 times the recommended maximum daily dose).
    Pharmacokinetics
    • Absorption: Pitavastatin peak plasma concentrations are achieved about 1 hour after oral administration.  Both Cmax and AUC0-inf increased in an approximately dose-proportional manner for single pitavastatin doses from 1 to 24 mg once daily. The absolute bioavailability of pitavastatin oral solution is 51%. Administration of pitavastatin with a high fat meal (50% fat content) decreases pitavastatin Cmax by 43% but does not significantly reduce pitavastatin AUC. The Cmax and AUC of pitavastatin did not differ following evening or morning drug administration. In healthy volunteers receiving 4 mg pitavastatin, the percent change from baseline for LDL-C following evening dosing was slightly greater than that following morning dosing. Pitavastatin was absorbed in the small intestine but very little in the colon.
    • Distribution: Pitavastatin is more than 99% protein bound in human plasma, mainly to albumin and alpha 1-acid glycoprotein, and the mean volume of distribution is approximately 148 L.  Association of pitavastatin and/or its metabolites with the blood cells is minimal.  
    • Metabolism: Pitavastatin is marginally metabolized by CYP2C9 and to a lesser extent by CYP2C8.  The major metabolite in human plasma is the lactone which is formed via an ester-type pitavastatin glucuronide conjugate by uridine 5'-diphosphate (UDP) glucuronosyltransferase (UGT1A3 and UGT2B7).      
    • Elimination: A mean of 15% of radioactivity of orally administered single 32 mg 14C-labeled pitavastatin dose was excreted in urine, whereas a mean of 79% of the dose was excreted in feces within 7 days.  The mean plasma elimination half-life is approximately 12 hours.  
    • Race: In pharmacokinetic studies pitavastatin Cmax and AUC were 21 and 5% lower, respectively in Black or African American healthy volunteers compared with those of Caucasian healthy volunteers.  In pharmacokinetic comparison between Caucasian volunteers and Japanese volunteers, there were no significant differences in Cmax and AUC.
    Counseling Points
    • Take pitavastatin at any time of the day with or without food
    • Instruct patients to promptly notify their physician of any unexplained muscle pain, tenderness, or weakness particularly if accompanied by malaise or fever.  
    • Discuss all medication, both prescription and over the counter, with their physician.  
    • Women of childbearing age should use an effective method of birth control to prevent pregnancy while using pitavastatin.  
    • Inform women who are breastfeeding to not use pitavastatin.  
    • Instruct patients that liver enzyme tests be checked before the initiation of pitavastatin and if signs or symptoms of liver injury occur.  Instruct patients to report promptly any symptoms that may include liver injury:
      • Fatigue
      • Anorexia
      • Right upper abdominal discomfort
      • Dark urine
      • Jaundice
