Thiopental sodiums are medications that are used to sedate and induce deep sleep during medical procedures. They belong to the class of drugs known as barbiturates, which act as central nervous system depressants. There are several synonyms for thiopental sodiums, including sodium thiopental, thiopentobarbital sodium, and pentothal sodium. These names are often used interchangeably in medical settings to refer to the same sedative drug. However, it is important to note that thiopental sodiums are highly potent and should only be administered by trained healthcare professionals in a controlled environment to prevent any complications or adverse reactions.
