Which of the following drugs falls under pregnancy category B?

Citanest is classified as a pregnancy category B drug. This category indicates that animal reproduction studies have not shown a fetal risk, but there are no adequate and well-controlled studies in pregnant women. Category B suggests that while there may not be enough evidence to deem it completely safe, it is generally considered safer than drugs in higher risk categories during pregnancy.

In the context of local anesthetics, Citanest (prilocaine) has been used in dental procedures and is seen as having a favorable safety profile regarding its effects during pregnancy. Understanding such classifications is critical for dental professionals when treating pregnant patients, ensuring that they utilize medications that pose the least risk to both the mother and the developing fetus.

In contrast, other options may fall into different pregnancy categories, which could indicate varying levels of risk associated with their use during pregnancy. For example, some may be classified as category C, indicating that they may pose a risk based on animal studies but lack enough human data to assess safety conclusively.
