<P> Some drug mechanisms of action are still unknown . However, even though the mechanism of action of a certain drug is unknown, the drug still functions; it is just unknown or unclear how the drug interacts with receptors and produces its therapeutic effect . </P> <Ul> <Li> Acamprosate </Li> <Li> Antidepressants </Li> <Li> Armodafinil </Li> <Li> Cyclobenzaprine </Li> <Li> Demeclocycline </Li> <Li> Fabomotizole </Li> <Li> Lithium </Li> <Li> Meprobamate </Li> <Li> Methocarbamol </Li> <Li> Paracetamol </Li> <Li> Phenytoin </Li> <Li> PRL - 8 - 53 </Li> <Li> Metformin </Li> <Li> Thalidomide </Li> </Ul> <Li> PRL - 8 - 53 </Li> <P> In some literature articles, the term mechanism of action and mode of action (MoA) are used interchangeably; typically referring to the way in which the drug interacts and produces a medical effect . However, in actuality, a mode of action describes functional or anatomical changes, at the cellular level, resulting from the exposure of a living organism to a substance . This differs from a mechanism of action, as it is a more specific term that focuses on the interaction between the drug itself and an enzyme or receptor and its particular form of interaction, whether through inhibition, activation, agonism, or antagonism . Furthermore, the term mechanism of action is the main term that is primarily used in pharmacology, whereas mode of action will more often appear in the field of microbiology or certain aspects of biology . </P>
