In utero drug therapy.
Drug therapy directed toward the fetus would be intended for either treating a fetal disorder or improving the capacity for later intrauterine or postnatal adaptation. Most reported trials involve single cases or small numbers of fetuses receiving the drug transplacentally after the first trimester, but before attaining maturity. Studies usually involve a single drug administered shortly before delivery. Treatments that are more direct or begun earlier in gestation are being attempted, but our limited understanding of fetal pharmacokinetics forces us to proceed cautiously. Studies to date have shown no risks to the mother and newborn infant, but long-term follow-up is necessary.
