Cardiovascular disease (CVD) is the leading cause of mortality worldwide in both sexes. drug groups. As far as cardiovascular prevention is concerned, sex-specific data is often lacking in clinical trials, highlighting the necessity to further study CVD and their treatment in both men and women. a range of complications such as stroke, acute coronary syndromes, chronic heart failure and chronic kidney disease. The most potent risk factors for heart failure in women are hypertension and diabetes. For men on the other hand, the main risk factor is coronary heart disease (Regitz-Zagrosek and Seeland, 2013). Epidemiological studies also show that women die more frequently from CVD Rabbit polyclonal to ISCU than men (Regitz-Zagrosek and Seeland, 2013). There is evidence of gender differences not only in the pathophysiology but also in the management and treatment of hypertension (Cadeddu et al., 2016). Furthermore, many studies highlight sex-differences in the pharmacokinetics (PK) of CV drugs. In this paper we review the known sexually dimorphic pharmacologic and more specifically pharmacokinetic differences. Our review focuses on differences in the main classes of antihypertensive drugs. Our aim is to discuss their clinical relevance, feasible impact in explaining the gender discrepancies in the mortality and morbidity of hypertension also to identify medical gaps. General PK PK describes the procedure that drugs and additional substances undergo in the physical body. The processes where the body grips medicines are absorption, distribution, elimination and metabolism. Gender variations in PK have already been described in a variety of studies because the 1970s. Nevertheless, the clinical implications of the differences are debated still. Data in this respect are sex-specific and scarce evidence-based recommendations are rare. Regarding absorption, in comparison to males, ladies have an increased gastric pH, slower gastric emptying and an extended total gastrointestinal (GI) transit period (Freire and Basit, 2011). The bioavailability could be suffering from These differences of medicines requiring an acidic environment for absorption and modified release formulations. Sex-differences in gastrointestinal cytochrome and Glutathione-S-transferase P450 enzymes have already been mentioned, although the amount of subjects in these studies is too low to draw meaningful Belinostat inhibitor database conclusions generally. Several studies possess found that men have higher levels of drug efflux pump glycoprotein P (P-gp) in the ileum (Anderson, 2008; Bebawy and Chetty, 2009; Regitz-Zagrosek and Seeland, 2013). However, a recent murine study performed a scan of the whole Belinostat inhibitor database intestine and found varying levels of P-gp throughout without any sex differences (Bebawy and Chetty, 2009). Drug distribution is dependent on multiple factors. Women generally weigh less than men and have a higher percentage of body fat. Thus, lipophilic substances will have Belinostat inhibitor database a higher volume of distribution (Vd) in women and hydrophilic substances a higher Vd in men. Women also have a lower plasma volume and lower average organ blood flow. These differences contribute to divergence in drug distribution and could Belinostat inhibitor database be considered in order to avoid unnecessary adverse reactions or optimize efficacy. Drug binding proteins are albumin, alpha1-acid-glycoprotein (AAG) and globulins. Albumin does not appear to be sex dimorphic, but estrogens reduce the plasma levels of AAG by inducing its hepatic glycosylation (Parekh, 2012; Spoletini et al., 2012). There is a large body of literature regarding variability in drug metabolism due to the influence of intrinsic and extrinsic factors. Table 1 summarizes sex differences in ghepatoc metabolism. Phase I reactions are primarily catalyzed from the cytochrome P450 category of enzymes (CYP). Males have already been regularly noted to possess higher actions of CYP 1A2 and CYP 2E1 (Anderson, 2005; Anderson, 2008; Parekh, 2012; Regitz-Zagrosek and Seeland, 2013). For CYP 2D6, some scholarly research found out higher actions in males, while others found out no variations (Anderson, 2005; Anderson, 2008). Ladies, alternatively, exhibit higher actions of CYP 3A4 and 2B6 (Anderson, 2005). CYP 3A4 can be mixed up in metabolism around 50% of medicines.
