    Various iron preparations may also con- tribute to constipation in the pregnant patient order allegra 120 mg on line. The majority of such agents are absorbed very little discount allegra 120mg visa, if at all cheap 180 mg allegra with mastercard, from the gas- trointestinal tract. Overall, they should have no systemic effects or pose any serious threat to the fetus. Simethicone is log- ically not expected to cause systemic effects or have access to the fetal–placental unit, because simethicone is not absorbed from the gastrointestinal tract. From a practical standpoint, it has no clear indications for use during pregnancy, nei- ther does this agent offer any advantage over simethicone. However, it should be used without hesitation when it is needed in the treatment of acute poisoning. This combination can be used safely in pregnancy, avoid- ing chronic high doses which pose a risk (hypercalcemia, etc). Laxatives and purgatives Laxatives/purgatives can generally be divided into several classes depending on the mode of action: (1) emollients and softeners; (2) bulk-forming agents; (3) stimulants; and (4) saline, hyperusmetic, or lubricant agents (Box 12. Chronic use of the agents should be avoided because diarrhea and electrolyte imbalances may occur. Congenital anomalies were not increased in frequency among the offspring of over 800 women who utilized this agent in early pregnancy (Aselton et al. Congenital anomalies were not increased in frequency among offspring of mothers who utilized either casanthranol (21 patients) or cascara sagrada (53 patients) in early pregnancy (Heinonen et al. It is very unlikely that it poses any risk to the fetus because this agent is mini- mally absorbed from the gastrointestinal tract. In one mouse study, decreased lit- ter size and fertility were observed, but no somatic effects (Anonymous, 1997). Although there are no human reproduction studies, this agent is not absorbed from the gastrointestinal tract for the most part, and thus is unlikely to be associated with adverse fetal effects. There are no published human epidemiological or animal teratology studies with this agent. However, chronic use of mineral oil as a lax- ative might interfere with the absorption of fat-soluble vitamins such as vitamin K and D, and thus theoretically could have adverse fetal effects. There are also no reports of an association of adverse fetal effects with the use of castor oil during pregnancy. It has been a commonly held belief that this agent would stimulate labor and it is often utilized for this purpose in women close to term. However, little scientific data support the use of this agent as a potent stimulant of labor. Antidiarrheal agents Unlike constipation, diarrhea is an uncommon complaint of pregnancy and is usually secondary to medications (especially antibiotics), infections (bacterial, viral, and para- 234 Nutritional and dietary supplementation during pregnancy Box 12. Fortunately, most cases of acute diar- rhea are self-limited and require no specific therapy. Antidiarrheals can generally be divided into three major categories – bulk- forming agents, absorbents, and opiates (Box 12. There are no epidemiological studies regarding the use of this agent in pregnant women. However, since very little, if any, of it is absorbed from the gastrointestinal tract, it seems very unlikely that this antidiarrheal poses a significant risk to either mother or fetus. The addition of belladonna and opioid agents results in decreased gastrointestinal mobility. There is little available information regarding the use of opium-containing agents in pregnant women. There were only 36 women with early pregnancy exposure included in the Collaborative Perinatal Project database, but there was no evidence of a significant increase in the frequency of congenital anomalies (Heinonen et al. Almost 100 women were exposed to paregoric in early preg- nancy with no significant increase in frequency of congenital anomalies (Aselton et al. There is, however, the possibility of addiction and withdrawal syndrome in neonates whose mothers use this agent on a chronic basis.

    T Efficacy markers generic allegra 180mg amex, finally purchase 180mg allegra with visa, describe how well a drug is working in an individual patient cheap allegra 180mg line. Example of cancer The fight against cancer is one of the greatest chal- prevention: early intesti- lenges facing modern medicine. According to an nal cancer detection estimate by the International Agency for Research on Cancer,part of the World HealthOrganization, over 1. Al- though screening programs are in place in most industrialised countries, people do not avail themselves of them to the neces- sary extent. Yet up to 90 percent of all fatal cases of intestinal cancer, says the German Felix Burda Foundation, could be pre- vented in the space of ten years by instituting a program of reg- ular endoscopic checks. The major misgiving is that although intestinal endoscopy is effective, it is also unpleasant and, being invasive,not without its risks. To date there is no screening meth- od that is able to identify high-risk patients simply and safely. The early detection of intestinal cancer still relies for the most part on the results of an occult blood test, which detects hidden (‘occult’) blood in the stool. Depending on the study con- cerned, however, this test fails to identify up to half of positive cases. In addition, one in five patients proves to be healthy after subsequent endoscopy. Given the large number of patients with intestinal cancer, medical researchers are therefore working in- tensively on alternatives to the occult blood test. Suitable screen- ing tests based on protein biomarkers could become available within just a few years. It is now known that over 100 different disorders – some degenerative, some inflammatory – are sub- sumed under the umbrella term ‘rheumatism’. That alone shows to what extent doctors have to depend on modern diag- nostic testing, especially since the right treatment often depends on the actual cause of the pain symptoms. Patients usually have to con- tend with severe pain and considerable impairment of move- ment. The causes of the disease are still unknown, but it appears certain that genetic predisposition, previous diseases and prob- ably also lifestyle are all factors. The best marker combinations searchers look for an optimum combination of markers therefore do not necessarily contain the best individual which together describe as many disease factors as markers. Treatment begins with diagnosis 63 The fact that diverse factors contribute to the development and progression of rheumatoid arthritis is also reflected in the search for suitable biomarkers. Not a single protein is known which can be used to diagnose a disease with absolute reliability – a fact that has become increasingly clear in recent years. All the molecular candidates so far tested either do not occur in all pa- tients or occur also in other inflammatory diseases. Biologists have therefore teamed up with mathematicians to develop a model to help in the search for an optimum combination of multiple markers (see box, p. Prospects: diagnostics Biotechnology has made key contributions not and treatment only to therapy but also to diagnostics. Armed evolve together with molecular diagnostic tests at the gene and protein levels, doctors can already search much more effectively for the causes of a patient’s illness and adapt the treatment accordingly, and not just in the early phases. Diagnostics, treatment and treatment monitoring are evolving together, and research in this area is being inten- sively pursued. The reasons for this are varied, ranging from differences in the immune re- sponse between individuals to significant variations in the ge- nome of the virus. Modern molecular diagnostic methods are there- fore needed not only at the start of the therapeutic process but throughout treatment. The more specifically a drug is directed against the cause of a disease, the more important it is for doctors to identify the cause accurately. For pharmaceutical companies that are active in both areas, this development has opened up a unique opportunity: Now diagnosis and therapy can be con- sidered together to help patients individually. Progress in the treatment of complex diseases in particular shows that molecular diagnostics holds new promises for med- Treatment begins with diagnosis 65 ical science.
