Introduction::
During pregnancy, the woman’s body undergoes anatomical
and physiological changes, making this period susceptible to maternal-fetal diseases and
complications. The consequences of not treating pregnant women include premature
birth, low birth weight fetuses, and postnatal behavior disorders. Developing new therapies
can accelerate the discovery of safe and effective drugs, contributing to designing
novel natural and synthetic products to treat complications the pregnancy.
Objective::
This study aimed to carry out a patent review to identify and explore trends
in innovation and therapeutic strategies for treating pregnant women.
Methods::
The Espacenet and WIPO databases were used, with the inclusion criteria being
the keywords “pregnancy and drug” and code A61k, from 2008 to 2023, and as exclusion
were the access to the patent and focus on human pregnant women.
Results::
After the final screening, 32 patents were selected, with strategies for the treatment
of diseases in pregnant women. Of these, 20 patents are on preclinical studies on
animals and 12 on pregnant women. It was observed that universities lead the ranking of
applications (17/32), and China has the highest number of patents (18/32). Most findings
contain herbal medicines and/or the association of natural extracts with synthetic
drugs.
Conclusion::
From this perspective, new drug administration systems were also developed,
which can be a promising source for obtaining new medicines for the treatment of
pregnant women; however, research is still limited and shows a gap in stimulating the
rapid development of safe drugs that improve the health of pregnant women.
