3 Investigations in the guinea pig and monkey also showed that bilirubin glucuronides do not cross the placenta in the reverse direction, from fetus to mother (1) Genetics: With maternal blood types A and B, isoimmunization does not occur because the naturally occurring antibodies (anti-A and -B) are IgM, not IgG

See more Passive diffusion is the predominant route by which drugs cross the placenta, and applies to molecules of less than 600 Da, which are hydrophobic and non-ionized
Antibiotics may be prescribed during pregnancy for bacterial infections
The first fetal organ drug encounters on crossing the placenta is the placenta itself
Macrobid is used to treat urinary tract infections
In the monochorial human placenta, drugs up to a molecular weight
Food contaminated with listeria can deposit the bacteria on counters, deli slicers and other surfaces where food is prepared and processed, where it can linger and
Background: Autoimmune hemolytic anemia (AIHA) is a rare entity during pregnancy
Prescription opioids are used prenatally for the management of pain, as well as for opiate dependency
It is unique in that it is a temporary organ; it grows alongside the fetus during pregnancy, and then is expelled along with the fetus at birth
Abstract
Most drugs cross the placenta by passive or facilitated diffusion
Rifampin
Why does IgM not cross the placenta? It is generated as a B cell membrane bound monomer and a secreted pentamer
For example, glycopyrrolate is a quaternary ammonium structure and does not cross the placenta readily as a result
The placenta is formed gradually during the first three months of pregnancy, while, after the fourth month, it grows parallel to the development of the uterus
During pregnancy, the placenta secretes hormones that increase insulin resistance, which may cause gestational diabetes (GD)
The main active chemical of marijuana (delta-9-tetrahydrocannabinol [THC]) readily crosses the placenta, and cannabinoid receptors have been identified in fetal brain and placenta

Over the course of your pregnancy, the placenta grows from a few cells into an organ that will eventually weigh about 1 pound
Nitrofurantoin was undetectable (<10 mcg/L) in all women before the first dose of the second day of administration with breakfast (fat content not stated)
