Members of this superfamily use ATP as an energy source, allowing them to pump substrates against a concentration gradient. In a series of studies, Rodeiro and others have shown the effects of mango on drug metabolizing enzymes and drug transporters [95, 96] They found that exposure of hepatocytes to mango extract produced a significant reduction (60%) in 7-methoxyresorufin-O-demethylase (MROD; CYP1A2) activity and an increase (50%) in 7-penthoxyresorufin-O-depentylase (PROD; CYP2B1) activity. Watch: Eat, drink, but be wary — 4 foods that interact with medications Grapefruit. The fruit may up blood levels of some medicines, like statins. consuming fruit. Recent studies show that some of these phytochemicals are substrates and modulators of specific members of the superfamily of ABC transporting proteins [26]. Cranberry juice may increase the bioavailability of CYP3A4 substrates (e.g., calcium antagonists or calcineurin inhibitors) as was discussed [61]. If you eat grapefruit or drink grapefruit juice at all, be aware that the fruit interacts with several... Kale. The nature of the interaction varies. Consequently, drug transporters in both the gut and the liver are important in determining oral drug disposition by controlling absorption and bioavailability [19]. It’s based on principles of collaboration, unobstructed discovery, and, most importantly, scientific progression. Response.redirect "/searchResults.asp?q=" & q Furthermore, cranberry juice increased the nifedipine concentration in rat plasma. Upon hydrolysis, glucoraphanin produces several products that include the bioactive isothiocyanate sulforaphane. medicines, it is not a complete list. Make sure to replenish these nutrients⁠—especially if you are taking omeprazole for an extended period⁠—by eating plenty of foods … It has been have also reported that a diet supplemented with apiaceous vegetables (dill weed, celery, parsley, parsnip) resulted in a 13-15% decrease in CYP1A2 activity [122]. The pungencyof red pepper is derived from a group of compounds called capsaicinoids, which possess an array of biological properties and give it its spicy flavor. It has been reported that polyphenols can potentially affect phase I metabolism either by direct inhibition of phase I enzymes or by regulating the expression of enzyme levels via their interactions with regulatory cascades. The active components of carrots, which include beta-carotene and panaxynol have been studied by many researchers [140-142]. In fact, there are dozens of drugs known to the U.S. Food and Drug Administration (FDA) that interact with grapefruit alone, including many over-the-counter drugs. Type I are ex vivo bioinactivations, which refer to interactions between the drug and the nutritional element or formulation through biochemical or physical reactions, such as hydrolysis, oxidation, neutralization, precipitation or complexation. Drug Interactions. How? Some of these food types are broken down into tyramine, which is then metabolized by monoamine oxidase enzyme. Winston H. Gandy Jr., a cardiologist with Piedmont Heart Institute in Atlanta and an American Heart Association volunteer, said these potential dangers don’t mean patients get a free pass when it comes to eating their veggies.It comes down to maintaining a careful balance when using anti-coagulants such as Coumadin (also known generically as warfarin and marketed under the brand names Marevan, Lawarin, Waran and Warfant).“… It has also been observed that components of orange juice -naringin in particular- are in vitro inhibitors of OATP transport activity [70]. Jones S., Preston C.L., Sandhu H. 2014. ► Fruit Interactions with Common Medicines, Prescriber Update 36(1): 4-5 that are metabolised by this enzyme. In some cases, you may need to avoid certain foods altogether during your treatment or … The irreversible inhibition of intestinal cytochrome P450 (CYP)3A4 enzymes by grapefruit juice is the most commonly identified mechanism mediating grapefruit drug interactions. Grapefruit ( Citrus paradisi). CYP3A4 metabolizes furanocoumarins found in grapefruit to reactive intermediates that then bond covalently to the active site of the enzyme, causing irreversible inactivation. Supplements can and do interact with medications in different ways, and even some fruits and foods can as well. ► Article Search These findings suggest that cranberry juice might affect the plasma concentration of nifedipine in humans as well [84]. Fruit juices contain a large number of phytochemicals that, in combination with certain drugs, can cause food–drug interactions that can be clinically significant and lead to adverse events. Isothiocyanates also interact with ATP-binding cassette (ABC) efflux transporters such as P-glycoprotein, MRP1, MRP2 and BCRP, and may influence the pharmacokinetics of substrates of these transporters [26]. There is also a report indicating that capsaicin is a substrate of CYP1A2 [155]. Extracts and metabolites of this plant, particularly those from the leaves and fruit, possess useful pharmacological activities [100]. Early studies demonstrated the influence of tangeretin, a flavonoid found in high levels in tangerine juice, on drug metabolizing liver enzymes. If you start your day with a cold glass, make sure you’re not mixing it with iron supplements, thyroid drugs… These proteins can be inhibited by orange, apple, and grapefruit juices. According to current data, watercress and isothiocyanate may have clinical repercussions by inducing changes in the bioavailability of some drugs. Berries have been shown to have a positive impact on several chronic conditions including obesity, cancer, and cardiovascular and neurodegenerative diseases [102-104]. Cranberries are a fruit chock full of vitamin C, and some people drink cranberry juice to help prevent urinary tract infections (UTI). The authors speculate that furanocumarins present in the apiaceous vegetables were responsible for the inhibitory effects on CYP1A2 ^115 [117,160]. Grapefruit. Drug–fruit/vegetable interaction and effects on bioavailability of drugs. Consumption of most types of orange juice does not appear to alter CYP3A4 activity in vivo [55]. Depending on your situation, it may be necessary to allow a certain time between the moment you eat and the moment you take your medication. 1. In industrialized countries, fruits and vegetables tend have been subjected to some sort of processing (e.g., refrigeration, acidification, fermentation, and thermal, high pressure, chemical, or physical processing) that might have an effect on the bioactive compound. For healthy-treatment intervention, it is necessary to understand how these drug-food interactions can induce a beneficial result or lead to detrimental therapeutic conditions (less therapeutic action or more toxicity). Resveratrol is an electron-rich molecule with two aromatic benzene rings linked by an ethylene bridge. We are a community of more than 103,000 authors and editors from 3,291 institutions spanning 160 countries, including Nobel Prize winners and some of the world’s most-cited researchers. One medical review advised patients to avoid all citrus. According to reports, PEITC also has several anti-carcinogenic effects given that it can inhibit phase I enzymes and/or activate phase II enzymes. Efflux transporters expressed in the intestine and liver include P-glycoprotein (Pgp, ABCB1), bile salt export pump (BSEP, ABCB11), multidrug resistance proteins (MRP1- 6, ABCC1-6), and breast cancer resistance protein (BCRP, ABCG2), all members of the ATP-Binding Cassette superfamily (ABC transporters) [23]. Drug interactions with ginger are not well documented; however, it is known to inhibit thromboxane synthetase, which can prolong bleeding time and may cause interactions with anticoagulants like warfarin, aspirin, or other blood thinners. By Lourdes Rodríguez-Fragoso and Jorge Reyes-Esparza, Submitted: November 18th 2011Reviewed: April 19th 2012Published: January 23rd 2013, *Address all correspondence to: mrodriguezf@uaem.mx. with medicine metabolism. Site Map, 0 Then Drug metabolism reactions are generally grouped into 2 phases. This group also studied the effect of mangiferin on CYP enzymes and found that mangiferin reduced the activities of five P450s: POD (CYP1A2), midazolam 1'-hydroxylation (M1OH; CYP3A1), diclofenac 4'-hydroxylation (D4OH; CYP2C6), S-mephenytoin 4'-hydroxylation (SM4OH), and chlorzoxazone 6-hydroxyaltion (C6OH; CYP2E1). Although modern medicine may be available in most countries for the treatment of many chronic degenerative diseases, folk medicine (phytomedicine) has remained popular for historical and cultural reasons. Patients may not recognize that otherwise healthy foods can have severe consequences when mixed with certain drugs. Table 1. Further research regarding the potential toxicities associated with flavonoids and other dietary phenolics is required if these plant-derived products are to be used as therapy. The potential for drug interactions with mango fruit should therefore be considered. Fruit juices contain a large number of phytochemicals that, in combination with certain drugs, can cause food–drug interactions that can be clinically significant and lead to adverse events. Some people are vegetarians, others take high doses of flavonoids or antioxidants as supplements, some ingest large amounts of bottled water from plastic bottles, or use chlorinated disinfectants. Seville oranges (often used to make orange marmalade), pomelos, and tangelos (a cross between tangerines and grapefruit) may have the same effect as grapefruit juice. There are numerous patients who encounter increased risks of adverse events associated with drug-nutrient interactions. Grapefruit is not the only citrus fruit that can interact with medications. However, the possibility that these effects could occur in humans should not be ignored. There is only one report about the effect of guava extracts on drug transport: guava extract showed a potent inhibitory effect on P-gp mediated efflux in Caco-2 cells. Cruz et al. Food-drug interactions can result in two main clinical effects: the decreased bioavailability of a drug, which predisposes to treatment failure, or an increased bioavailability, which increases the risk of adverse events and may even precipitate toxicities (See Figure 1) [4, 10,11]. Drug interaction with any of these substances may enhance or decrease the effect of Amlodipine. with common medicines. When CYP3A4 is inhibited, it can result in increased concentrations of medicines Lourdes Rodríguez-Fragoso and Jorge Reyes-Esparza (January 23rd 2013). Fruits associated with medicine interactions include orange, pomelo, It is important to know if you need to avoid any Food, Herbs, or Alcohol when taking Amlodipine. The foods we eat can interfere with the medications we take. Variability in fruit strains, environmental conditions, processing procedures, How Grapefruit Juice Can Interfere With Medications. Watercress is another important member of the cruciferous vegetables, an excellent source for glucosinolates and other bioactive phytochemicals [124]. Type II interactions affect absorption. Vegetables such as cabbage, celery, onion and parsley are known to have a high content of polyphenols. Metoprolol Interactions with Food and Herbs Potassium Rich Foods: Metoprolol is a beta blocker which increases the potassium level in the blood. About Drug-fruit/vegetable interaction and effects on bioavailability of drugs. Dietary habits are an important modifiable environmental factor influencing human health and disease. These findings suggest that mango and its components inhibit the major human P450 enzymes involved in drug metabolism and some transporters. A number of metabolites such as phenolics, flavonoid, carotenoid, terpenoid and triterpene have been found in this fruit. However, orange juice made from Seville oranges appears to be somewhat similar to grapefruit juice and can affect the pharmacokinetics of CYP3A4 substrates [68]. Blood pressure medications are one example of drugs … The mechanism behind this interaction might be the inhibition by cranberry flavonoids of CYP3A4 and/or CYP2C9 enzymes, which are responsible for warfarin metabolism [31,82]. Pomegranate is commonly eaten around the world and has been used in folk medicine for a wide variety of therapeutic purposes [85-86]. Oral administration of drugs, however, may lead to limited and variable oral bioavailability because of absorption across the intestinal barrier [15,16]. juices or concentrates are frequently used as bases for fruit drinks, often Platt and others [132] reported the protective effect of spinach against the genotoxic effects of 2-amino-3-methylimidazo[4,5-f]quinoline (IQ) by interaction with CYP1A2 as a mechanism of anti-genotoxicity. Grapefruit juice was chosen as the mixer for its bitter taste, to disguise whether not alcohol was present. to the Centre for Adverse Reactions Monitoring (CARM). By Jolanta Natalia Latosińska and Magdalena Latosińska. The SLC superfamily encompasses a variety of transporters, including the organic anion transporters (OAT, SLC22A), the organic cation transporters (OCT, SLC22A), the electroneutral organic cation transporters (OCTN, SLC22A), the equilibrative nucleoside transporters (ENT, SLC29), the concentrative nucleoside transporters (CNT, SLC28), the apical Na+−dependent bile salt transporter (ASBT, SLC10), the monocarboxylate transporters (MCT, SLC16), and the peptide transporters (PEPT, SLC15) [21]. These diets are often maintained for long periods of time and are likely to result in metabolic changes due to subsequently administered drugs or exposure to environmental chemicals. © 2013 The Author(s). Low fruit and vegetable intake is among the top 10 risk factors contributing to mortality. Watercress (Nasturtium officinale) is an exceptionally rich dietary source of beta-phenylethyl isothiocyanate (PEITC) [125]. Nagata and others [88] found that pomegranate juice inhibited human CYP2C9 activity and increased tolbutamide bioavailability in rats. These interactions usually occur in the delivery device. Recently, it has been evidenced that red pepper induces alterations in intestinal brush border fluidity and passive permeability properties associated with the induction of increased microvilli length and perimeter, resulting in an increased absorptive surface for the small intestine and an increased bioavailability not only of micronutrients but also of drugs [157]. Some fruit juices and fruits can interact with numerous drugs, in many cases causing adverse effects. Inhibition of CYP enzymes, which are necessary for carcinogen activation, is a beneficial chemopreventive property of various flavonoids but may be a potential toxic property in flavonoid-drug interactions. Blood pressure medications are one example of drugs that can be affected by the food you eat. The beneficial effects of mango include anti-inflammatory and antimicrobial activities [90,91] Preliminary phytochemical screening revealed the presence of flavonoids, including quercetin and glycosylated xanthones such as mangiferin [92,93] Quercetin has been shown to possess antioxidant, antimicrobial, antitumor, antihypertensive, antiatherosclerosis, and anti-inflammatory properties [94]. On the other hand, the Phase II drug metabolizing or conjugating enzymes consist of many enzyme superfamilies, including sulfotransferases (SULT), UDP-glucuronosyltransferases (UGT), DT-diaphorase or NAD(P)H:quinone oxidoreductase (NQO) or NAD(P)H: menadione reductase (NMO), epoxide hydrolases (EPH), glutathione S-transferases (GST) and N-acetyltransferases (NAT). Our knowledge regarding the potential risk of nutrient-drug interactions is still limited. Raspberry or raspberry constituents have antioxidant and anti-inflammatory properties, and inhibit cancer cell growth [105-107]. In vivo studies on the interaction between black mulberry and black raspberry and CYP3A substrates are needed to determine whether inhibition of CYP3A activity by fruit juices is clinically relevant. Seville oranges, pomelos and tangelos can have the same effect on drugs as grapefruit, so best to avoid them if you know your drug can interact with grapefruit. Medicines can interact with whole fruit, fruit pulp or fruit Hence, if patients eat these … Resveratrol was shown to be an irreversible (mechanism-based) inhibitor of CYP3A4 and a non-competitive reversible inhibitor for CYP2E1 in microsomes from rat liver and human liver cells containing cDNA-expressed CYPs [77,78](Chan and Delucchi 2000; Piver and others 2001). Unfortunately, the potentially toxic effects of excessive flavonoid intake are largely ignored. In other cases, as with the antihistamine fexofenadine (Allegra), grapefruit and grapefruit juice decrease both the blood levels of the drug and its effectiveness. Thus, the possibility of adverse food-drug interaction involving papaya and medicine acting via CYP3A metabolism should be examined in vivo. Carrots (Daucus carrota) are widely consumed as food. CYP proteins are categorized into families and subfamilies and can metabolize almost any organic xenobiotic [35]. Therefore, a potential interaction may occur when is taken along with some medicines that are CYP450 substrates. In addition, various dietary components can have pharmacological activity under certain circumstances [12]. The bioavailability of drugs has been reported to be doubled by grapefruit juice, even when taken 12 h after ingestion. These results suggest that black raspberry and black mulberry may decrease the plasma concentrations of concomitantly ingested OATP-B substrate drugs or increase the plasma concentration levels of concomitantly ingested CYP3A-substrate drugs. During the consumption of drugs with fruits or vegetables, the ADME properties of drug (absorption, distribution, metabolism, and excretion) can be modified by drug–phytochemical interaction. But even healthy foods, including fruits and vegetables, can cause unintended and possibly dangerous interactions with certain medications. Inhibition of CYP activities by flavonoids has been extensively studied because of their potential use as blocking agents during the initial stage of carcinogenesis [174]. this Site  |  FAQs  |  Like other fruits, raspberries contain micro- and macronutrients such as vitamins, minerals, and fiber. Vegetarians, on the other hand, exhibit a wide diversity of dietary practices often described by what is omitted from their diet. Patients consuming red pepper and taking antidiabetic therapy could suffer potential drug-food interaction. Type III interactions affect the systemic or physiologic disposition and occur after the drug or the nutritional element has been absorbed from the gastrointestinal tract and entered the systemic circulation. Growing evidence on the health benefits of avocadoes have led to increased consumption and research on potential health benefits [145, 146]. Such inhibition of the enteric CYP3A activity by a single exposure to pomegranate juice appears to last for approximately 3 days [56]. Opt for other fruits like kiwi fruit, blood oranges and other fresh produce instead, suggests Kennedy. fruit jams/marmalades, fruit extracts and even cooked products such as sauces effect of affected medicines. Dresser et al., have previously reported that orange juice inhibits the function of human OATP-A (OATP1A2, gene symbol SLC21A3/SLCO1A2) in vitro [29]. Prescription medications are generally safe and effective, but many of them can interact poorly with certain foods. If you are taking any medications, check the drug safety information carefully for any food interactions. Dairy products such as milk, yogurt, and cheese can interfere with … The cytochrome p450 isoenzyme, CYP3A4, is inhibited by the flavonoid, naringin, Phase II reactions use an endogenous compound such as glucuronic acid, glutathione, or sulfate, to conjugate with the drug or its phase I–derived metabolite to produce a more polar end product that can be more readily excreted [33]. Phytochemicals extracted from avocado can selectively induce several biological functions [147,148]. and patient factors make it difficult to predict whether a fruit or fruit Fruit/Vegetable-Drug Interactions: Effects on Drug Metabolizing Enzymes and Drug Transporters, Drug Discovery, Hany A. El-Shemy, IntechOpen, DOI: 10.5772/48283. A number of foods can interact with medication and impact their efficacy or cause side effects. Broccoli (Brassica oleracea var. 1 The use of natural products for improving human health has evolved independently in different regions of the world and production, use, attitudes, and regulatory aspects vary globally. It is possible that other fruits and vegetables could have the same potential for fruit and drug interactions, and this should be taken into account. A number of foods can interact with medication and impact their efficacy or cause side effects. On the other hand, Imaizumi et al. Most of the documented information about the effects of fruit and vegetables on metabolizing enzymes and drug transporters comes from preclinical studies. Perhaps the best-known example is grapefruit, which, along with pomegranate, can alter the way certain cholesterol medications work. As a result of this, interaction can be increased or decreased plasma concentrations of a drug that can lead to the presence of adverse … As a result of these factors, vegetarians typically have a lower body mass index, low-density lipoprotein cholesterol levels, and lower blood pressure; a reduced ischemic heart disease death rate; and decreased incidence of hypertension, stroke, type 2 diabetes, and certain cancers that are more common among non-vegetarians [167]. Tomatoes are also a source of a vast array of flavonols (e.g., quercetin and kaempferol), phytosterols, and phenylpropanoids [135]. It has been suggested that lycopene might have a potential advantage over other phytochemicals by facilitating the elimination of genotoxic chemicals and their metabolites [138]. Grapefruit juice (GFJ)-drug interactions have received extensive interests from the scientific, medical, regulatory and general communities because GFJ can strongly interfere with the disposition of substrates of cytochrome P450 (CYP)3A and/or P-glycoprotein (P-gp). As a result of this interaction can be increased or decreased plasma concentrations of a drug which can lead to the presence of adverse events or treatment failure. Previous studies have shown that a single ingestion of watercress inhibits the hydroxylation of chlorzoxazone, an in vivo probe for CYP2E1, in healthy volunteers [126]. Pharmacokinetic studies in animals have shown that a single dose of Capsicum fruit could affect the pharmacokinetic parameters of theophylline, while a repeated dose affected the metabolic pathway of xanthine oxidase [156]. Login to your personal dashboard for more detailed statistics on your publications. Publications product will lead to a medicine interaction. Here, we review some of the most widely consumed fruits and vegetables to inform healthcare providers of possible nutrient-drug interactions and their potential clinical significance. Publishing on IntechOpen allows authors to earn citations and find new collaborators, meaning more people see your work not only from your own field of study, but from other related fields too. The major uptake transporters responsible for nutrient and xenobiotic transport, both uptake and efflux transporters, belong to the two solute carrier (SLC and SLCO) superfamilies [20]. Such adversities have spurred various pre-clinical and in vitro investigations on a series of other herbal remedies, with their clinical relevance yet to be established. An increase in hGSTA1/2 mRNA has been observed in isothiocyanate sulforaphane-treated human hepatocytes, whereas the expression of CYP3A4, the major CYP in the human liver, markedly decreased at both mRNA and activity levels [121]. We are IntechOpen, the world's leading publisher of Open Access books. Red pepper (Capsicum annuum L.) is used as a spice that enhances the palatability of food and drugs such as the counterirritant present in stomach medicines across many countries [151]. have reported capsaicinoid-induced changes of glucose in rats. Often, influence on drug metabolism by compounds that occur in the environment, most remarkably foodstuffs, is bypassed. Epidemiologic evidence suggests that regular consumption of fruits and vegetables may reduce risk of some diseases, including cancer [1]. Black raspberries (Rubus coreanus) have been called the “king of berries” for their superior health benefits, whereas black mulberry (Morus nigra) is most commonly used for its antioxidants properties and for its high bioactive content of phenolics, anthocyanins, and gallic acid. CYP2C9, may be inhibited by pomegranate and cranberry juices.1. Devices Safety Authority, www.medsafe.govt.nz/profs/PUArticles/P-glycoproteinSept2011.htm, Medicines Adverse Reactions These whole fruit It has been shown that black raspberry and black mulberry are able to inhibit the human CYP3A-catalyzed midazolam 1-hydroxylation activity in liver microsomes, and the inhibitory effects are somewhat greater than those of pomegranate [49, 56]. 1, Some fruits contain flavanoids and furanocoumarins which can interfere Phenolic compounds may help protect the gastrointestinal tract against damage by reactive species present in foods or generated within the stomach and intestines.
