which fruits interact with medications

These interactions usually occur in the delivery device. Fruit baskets are a great gift idea, especially for the person who has everything; however, seemingly innocent citrus gifts may interact with some medications. 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. 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). How? 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. One interesting characteristic of this interaction is that grapefruit juice does not need to be taken simultaneously with the medication in order to produce the interaction. Two papers published in the 1990’s reported avocados interact with warfarin, stating that the fruit inhibited the effect of warfarin. 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. Lourdes Rodríguez-Fragoso and Jorge Reyes-Esparza (January 23rd 2013). Presumably, the mechanism of this effect is similar to that of grapefruit juice-mediated interactions, because Sevilla orange contains significant concentrations of flavonoids, mainly bergamottin and 6´,7´-dihydroxybergamottin [69]. Herbal medicines such as St. John's wort, garlic, piperine, ginseng, and gingko, which are freely available over the counter, have given rise to serious clinical interactions when co-administered with prescription medicines [42]. Little is currently known about the in vivo effects these compounds have on the bioavailability of xenobiotics the clearance and/or tissue distribution of which is determined by active transport and biotransformation. 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. (5) Beef liver, sausage, and cheese. and patient factors make it difficult to predict whether a fruit or fruit consuming fruit. Cranberry juice may increase the bioavailability of CYP3A4 substrates (e.g., calcium antagonists or calcineurin inhibitors) as was discussed [61]. The predominant mechanism for this interaction is the inhibition of cytochrome P-450 3A4 in the small intestine, which results in a significant reduction of drug presystemic metabolism. In fact, it can help reverse a condition or reduce the need for medication. It was also found to inhibit efflux transport from serosal to mucosal surfaces in the rat ileum [101]. Until recently, little regard was given to the possibility that food and food components could cause significant changes to the extent of drug absorption via effects on intestinal and liver transporters. Some of these chemicals are also found in other fruit juices. Nutritional status and diet can affect drug action by altering metabolism and function. The conjugation reactions by Phase II drug-metabolizing enzymes increase hydrophilicity and thereby enhance excretion in the bile and/or the urine and consequently affect detoxification [36]. 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. 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]. An interaction is considered significant from a clinical perspective if it alters the therapeutic response. Adding watercress juice to human liver cells induced the activity of CYP4501A and ethoxyresorufin-O-deethylase and NAD(P)H-quinone reductase [127]. Flavonoids can either inhibit or induce human CYP enzymes depending on their structure, concentration, or experimental conditions [176]. Furthermore, cranberry juice increased the nifedipine concentration in rat plasma. March 2015, Medicine interactions with grapefruit juice are well-known. Type II interactions affect absorption. However, they are also present in the large and small intestine, lungs and brain [34]. Statins. A drug-nutrient interaction is defined as the result of a physical, chemical, physiological, or pathophysiological relationship between a drug and a nutrient [8,9]. Our team is growing all the time, so we’re always on the lookout for smart people who want to help us reshape the world of scientific publishing. One medical review advised patients to avoid all citrus. The observed induction and inhibition of CYP enzymes by natural products in the presence of a prescribed drug has (among other reasons) led to the general acceptance that natural therapies can have adverse effects, contrary to popular beliefs in countries with active ethnomedicinal practices. found that papaya produced an inhibition of CYP3A activity in human microsomes [114]. On the other hand, Satoh et al. There is also a report indicating that capsaicin is a substrate of CYP1A2 [155]. This is achieved by an increased consumption of fruits, vegetables, whole-grains, legumes, nuts, and various soy products. Don't eat it if you take a range of medicines including some lipid-altering agents/statins … In other cases, as with the antihistamine fexofenadine (Allegra), grapefruit and grapefruit juice decrease both the blood levels of the drug and its effectiveness. The empirical evidence regarding the wide use of fermented papaya preparation (FPP), especially by elderly people, has indicated an unknown collateral effect, i.e., drops in blood sugar levels, especially in the afternoon. Several epidemiologic, clinical, and experimental studies have established that certain types of diet may have beneficial effects on health. Table 1. Common foods, such as fruits and vegetables, contain a large variety of secondary metabolites known as phytochemicals (Tabla 1), many of which have been associated with health benefits [25]. pomegranate, cranberry, grape, apple, and grapefruit. On the other hand, it has also been reported that apple juice and its constituents can interact with members of the OATP transporter family (OATP-1, OATP-3 and NTCP) by reducing their activities in vitro. Metoprolol Interactions with Food and Herbs Potassium Rich Foods: Metoprolol is a beta blocker which increases the potassium level in the blood. 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). In the case of many drugs, an increase in serum drug concentration has been associated with increased frequency of dose-dependent adverse effects [65-67]. Grapefruit (as well as pomelo, lime, and Seville oranges) contains a substance that reduces the ability of the liver to break down and eliminate certain medications, especially those used to lower cholesterol, treat hypertension or arrythmia, or those that act on the immune system. Patients may not recognize that otherwise healthy foods can have severe consequences when mixed with certain drugs. 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. Grapefruit interferes with your body's metabolism of atorvastatin (Lipitor), simvastatin (Zocor) and lovastatin (Altoprev, Mevacor), so your intended dose might not be accurate. 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. Said approach must be systematic in order to a) assess the influence of nutritional status, foodstuffs, or specific nutrients on a drug’s pharmacokinetics and pharmacodynamics, and b) evaluate the influence of a drug on overall nutritional status or the status of a specific nutrient. However, orange juice made from Seville oranges appears to be somewhat similar to grapefruit juice and can affect the pharmacokinetics of CYP3A4 substrates [68]. Raspberry or raspberry constituents have antioxidant and anti-inflammatory properties, and inhibit cancer cell growth [105-107]. Grapefruit Warning: It Can Interact with Common Medications Grapefruit is a delicious citrus fruit with many health benefits. Izzo [81] described a total of eight cases of interaction between cranberry juice and warfarin, leading to changes in international normalized ratio (INR) values and bleeding. It has also been shown that watercress is a bifunctional agent with the ability to induce both phase I (CYP450) and II enzymes. There are numerous patients who encounter increased risks of adverse events associated with drug-nutrient interactions. There are currently few studies that combine a nutrient-based and detailed pharmacological approach [4], or studies that systematically explore the risk and benefits of fruit and vegetables [5-7]. Drug–fruit/vegetable interaction and effects on bioavailability of drugs. For this reason, this fruit should be consumed with caution by patients taking medicines. In addition, polyphenols have been shown to interact with ABC drug transporters involved in drug resistance and drug absorption, distribution and excretion [32]. 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. Capsaicin is known to have antioxidant properties and has therefore been associated with potent antimutagenic and anticarcinogenic activities [153]. Guava is an important food crop and medicinal plant in tropical and subtropical countries; it is widely used as food and in folk medicine around the world [98, 99]. These findings suggest that mango and its components inhibit the major human P450 enzymes involved in drug metabolism and some transporters. How Grapefruit Juice Can Interfere With Medications. Help us write another book on this subject and reach those readers. italica) and cauliflower (Brassica oleracea var. Unfortunately, the potentially toxic effects of excessive flavonoid intake are largely ignored. HeadquartersIntechOpen Limited5 Princes Gate Court,London, SW7 2QJ,UNITED KINGDOM. Orange juice might reduce the intestinal absorption of substrates of OATP-B (e.g., digoxin, benzylpenicillin, and hormone conjugates), resulting in a decrease in concentration in the blood. medicines, it is not a complete list. As a consequence, there is an increased global consumer demand for fruits and vegetables, and some consumers purchase organic foods with the understanding that they are healthy. To date our community has made over 100 million downloads. It has been reported that a carrot diet increased the activity of ethoxycoumarin O-deethylase ECD activity in a mouse model [143]. When a vegetarian diet is appropriately planned and includes fortified foods, it can be nutritionally suitable for adults and children and can promote health and lower the risk of major chronic diseases [166]. Other reports indicate that orange juice slightly reduced the absorption of ciprofloxacin, levofloxacin and celiprolol [65] A study of an interaction between orange juice and pravastatin showed an increase in AUC [54].Orange juice also moderately reduces the bioavailability of atenolol, which may necessitate a dose adjustment [71,72]. proteins which facilitate substance uptake. Grapefruit ( Citrus paradisi). Red pepper has several uses as a fruit stimulant and rubifacient in traditional medicine; it is also used in the treatment of some diseases such as scarlatina, putrid sore throat, hoarseness, dispepsia, yellow fever, piles and snakebite [152]. Stockley's Drug Interactions. Several findings showed that grapefruit juice had a major effect on the intestinal CYP system with a minor effect at the hepatic level [48]. Papaya is prized worldwide for its flavor and nutritional properties.

The precipitant agent may modify the function of enzymes or transport mechanisms that are responsible for biotransformation. However, several reports have examined the effects of plant foods and herbal medicines on drug bioavailability. Quinolone antibiotics like Cipro (ciprofloxacin), levofloxacin and Avelox … as well the furanocoumarins bergamottin and 6',7'-dihydroxybergamottin.1 Vegetarians, on the other hand, exhibit a wide diversity of dietary practices often described by what is omitted from their diet. Some of these food types are broken down into tyramine, which is then metabolized by monoamine oxidase enzyme. Antibiotics & dairy products. this Site  |  FAQs  |  Often, influence on drug metabolism by compounds that occur in the environment, most remarkably foodstuffs, is bypassed. 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. Therefore, efforts to elucidate potential risk of food-drug interactions should be intensified in order to prevent undesired and harmful clinical consequences. Orange juice and its constituents were shown to interact with members of the OATP transporter family by reducing their activities. product will lead to a medicine interaction. CYP3A4 metabolizes furanocoumarins found in grapefruit to reactive intermediates that then bond covalently to the active site of the enzyme, causing irreversible inactivation. Prescription medications are generally safe and effective, but many of them can interact poorly with certain foods. Berries have been shown to have a positive impact on several chronic conditions including obesity, cancer, and cardiovascular and neurodegenerative diseases [102-104]. In addition, various dietary components can have pharmacological activity under certain circumstances [12].
