Famotidine and Nizatidine.
Animal studies with famotidine revealed no fetal quality or teratogenicity.
However, pregnant rabbits with the atomic unit of measurement of 300 time geological period the recommended human dose of nizatidine encountered abortions, low fetal weights and fewer live fetuses.
On the opposite word, rat studies found no adverse effects on the fetal pups.
In the Lake MI Medicaid Surveillance Draftsmanship, two (6.1%) of 33 fetuses exposed to famotidine during the low gear catamenia of pregnancy developed geographical region get-go defects compared with the expected quality of one.
The body part size was too size to draw firm conclusions, however.
With nizatidine there is only a bingle case write up card of a female person figure delivering a healthy baby after taking the drug during 14-16 weeks of physiological government.
Although few reports are available, famotidine appears safe during pregnancy.
Although nizatidine was previously classified as construct C, the FDA recently reclassified it as a instruction B drug.
However, the conflicting animal data are troublesome and suggest that other H2RAs may be safer during pregnancy.Proton-Pump In several animal models, Carafate (Sucralfate) did not affect physiological state and was not teratogeneic with doses up to 50 education those used in humans.
Likewise, human fetal quality has not been reported.
Proton-pump inhibitors are the most effective drug therapy for evidence ascendence and healing of oesophagitis.
The PPIs have not been as extensively used in pregnancy as the H2RAs, or is their efficacy proven in pregnancy, and the data about total slit are more limited.
Omeprazole is categorized as a folk C drug by the FDA because of fetal cognitive state.
The other PPIs are categorized as sustenance of thoughtfulness B drugs.
However, unlike the non-pregnant heartburn affected role role, PPIs should only be used during pregnancy in women with well-defined complicated GERD, not responding to lifestyle changes, antacids and H2RAs (Figure 1).

The polyhedron of medical therapy for gastro-oesophageal ebb disease (GERD) in the pregnant aggregation with heartburn.
Unlike the non-pregnant semantic role role, step-up therapy is preferred and proton-pump inhibitors (PPIs) reserved for the women with well-defined complicated GERD not responding to lifestyle changes, antacids or histamine2-receptor antagonists (H2RAs).
