With the great advance in molecular biology and biotechnology, many drug transporters have been identified and characterized over the last 10 years. In spite of a large body of information on the kinetic characterization of transporters in cell culture models and heterolo- gous expression systems, there are still large gaps in our knowledge about how to utilize the information obtained from in vitro studies to interpret the in vivo kinetic behavior of drugs and for developing new drug candidates that are absorbed, distributed, or excreted by means of transporters (1,2). In addition, the cellular localization and transport direction of the transporter are also important factors that must be considered. Another factor that adds to the complexity of in vivo function of drug transporters is that they interplay with drug-metabolizing enzymes (3,4). It is well known that there is a striking overlap of substrate specificity between drug transporters and drug-metabolizing enzymes (1,2). Therefore, it is important to dissect the function of drug trans- porters from that of drug metabolizing enzymes when assessing drug inter- actions. Experimentally, it is very difficult to accurately differentiate the relative role of a particular transporter from drug-metabolizing enzymes or other trans- porters. The relative role of a given transporter that interplays with other trans- porters is further complicated by the fact that many drug transporters may not have yet surfaced. It is expected that many new drug transporters will continue to emerge in the future. In many cases, transporter-mediated interactions are postulated on the basis of circumstantial evidence. Therefore, care should be exercised when exploring the under- lying mechanisms of drug interactions. The main purpose of this chapter is to explore the molecular mechanisms of drug interactions involving drug trans- porters. While the discussion will be focused predominantly on human data, examples from animal studies will also be used to assist in our understanding of the transporter-mediated drug interactions. In fact, there are many conflicting reports with regard to the interpretation of the underlying mechanisms for the so- called transporter-mediated drug interactions. Limited knowledge about the inhibition and induction of transporters at the molecular level is one of the major reasons. The Transporter-Mediated Drug Interactions 547 molecular mechanisms of inhibition and induction for most drug transporters are still not fully understood up to date. Inhibition of Transporters The inhibition of transporters does not always follow simple kinetics. Taken together, these results highlight the complexity of the competitive inhi- bition of P-gp by two drug substrates. Although the competition of two substrates for the same P-gp normally results in an inhibitory effect on the P-gp-mediated transport of the substrates, stimulation of P-gp-mediated efflux transport has been reported in some cases. Inter- estingly, Hoechst 33342 transport was increased by daunorubicin and doxorubicin, while rhodamine 123 transport was inhibited by daunorubicin and doxorubicin (14). These results strongly suggest that molecular mechanisms of P-gp interaction are quite complex and cannot be predicted readily. Similar to efflux transporters, the inhibition of influx transporters also does not always follow simple kinetics. Because of the complexity, it is difficult to predict the magnitude of drug interactions via transporter inhibition when transporter substrates and inhibitors are given simultaneously. This complexity can be further exacerbated by recent find- ings that inhibition of the transport of a substrate could result from alterations in the so-called transporter trafficking/sorting processes of endocytic retrieval and exo- cytic insertion of transporters between the apical membrane and intracellular pools of vesicles caused by a second substrate (21,22).

No studies have been published regarding congenital anomalies among the offspring of women who took this drug in the first trimester discount zofran 4mg line medicine for stomach pain. In experimental animal studies (hamsters generic zofran 8 mg visa treatment hypercalcemia, mice), the frequency of congenital anom- alies was not increased among offspring exposed to naloxone at many times the usual human dose (Geber and Schramm, 1975; Jurand, 1985). It is well known that naloxone may precipitate withdrawal symptoms in newborns whose mothers are addicted to nar- cotics, and who used very high doses of narcotics near the time of delivery. No studies have been published on congenital anomalies after exposure to naltrexone during embryogenesis. Three case series comprising reportedly nonoverlapping patients contained 31 infants whose mothers used naltrexone during the first trimester, and there were no congenital anomalies present (Hulse and O’Neil, 2002; Hulse et al. Notably, these gravidas were given naltrexone as part of a treatment regimen for heroin addiction. According to its manufacturer, this agent was shown to be embryocidal in animal studies. Independent investigators have reported no increased frequency of congenital anomalies among rats or rabbits exposed during embryogenesis. Butalbital is usually combined with aspirin or acetaminophen (with or without caffeine). The most common indication for butalbital-containing analgesic compounds is tension headaches. Barbiturate use in the first trimester was not associated with an increase in the frequency of congenital anomalies in exposed offspring. However, barbiturates have been associated with fetal dependence and newborn withdrawal symptoms when used chronically by the mother in the third trimester. Medical compounds comprised of isometheptene, dichloralphenazine and acetamino- phen (Midrin, Amidrin, Migratine) are used to treat vascular headaches or migraines. This combination is commonly used during pregnancy, but no stud- ies of the risk of congenital anomalies are available for two of the components (isometheptene, dichloralphenazine). Sumatriptan and other triptans Sumatriptan (Imitrex) is a selective 5-hydroxytryptamine receptor agonist. Among 658 infants born to women who used sumatriptan during the first trimester, the frequency of congenital anomalies was no greater than expected (Kallen and Lynger, 2001). According to its manufacturer, it has been shown to cause malformations in rabbits but was not teratogenic in rats. Using the ex vivo isolated perfused cotyledon technique, sumatriptan crossed the placenta by passive transport in the ex vivo isolated perfused cotyledon technique (Schenker et al. Promethazine, in a dose of 25 mg, is also usually given as an adjunct to prevent nausea (Table 8. Analgesia following minor procedures Several oral narcotic agents (hydrocodone, oxycodone) provide satisfactory relief for mod- erate pain associated with minor surgical procedures, such as dental procedures. Narcotic agents should not be used over a protracted period of time (more than 7 days) late in preg- nancy because of the potential for neonatal dependence or withdrawal symptoms. Headache Headaches are common during pregnancy and may increase in frequency during gesta- tion. In all headache syndromes, potential identifiable causes of headaches should be ruled out before a long-term treatment plan is implemented. Headaches are divided into two major categories: (1) tension and (2) vascular (migraine). For mild to moderate headaches, aspirin, acetaminophen, ibuprofen, or naproxen usually provide satisfactory relief. Aspirin should be avoided during pregnancy for hematologic reasons, and especially when headaches occur close to term. If other agents have failed, ibuprofen appears to pose the least risk for increased bleeding and premature ductus closure. Migraine (vascular) headaches are difficult to treat during pregnancy, and they seem to increase in frequency during gestation. The vasoconstrictive agent, ergotamine, is one of the agents used to treat migraine headaches in the nonpregnant patient; however, it is not recommended for use during pregnancy because it has (1) vasoconstrictive and (2) oxy- tocin-like actions. Propranolol at a dose of 40 mg or higher per day (several divided doses) has been effective for the treatment of some migraines in the pregnant patient, and poses a negligible risk to the unborn child. Amitriptyline, a tricyclic antidepressant, has been used to treat migraine headaches in pregnant women.
