Yes, neostigmine, a quaternary ammonium compound, is a small molecule capable of crossing the placental barrier [1.3.8]. This placental transfer is a critical consideration for its use in pregnant patients, particularly for anesthesia reversal and managing myasthenia gravis.

It is estimated that most medications administered to a pregnant mother will cross the placenta to some degree. A complex interplay of drug characteristics, transport mechanisms, and physiological changes determines precisely **how drugs are transferred across the placenta**.
