Because antimicrobial surfactant-like peptides kill bacteria/fungi via disrupting the membranes, it is less likely for the microorganisms to develop resistance. Associations of two or more drugs with at least one of them to be an antimicrobial peptide have contributed to the treatment of difficult-to-treat infectious diseases caused by pathogens in numerous <em>in vitro</em> studies. The synergistic action of cationic antimicrobial peptide or surfactant-like molecule with a current antibiotic can bring an effective measure to overcome antimicrobial resistance. Through reviewing recent advances in combinatorial therapies, we show that synergy between different agent types could be a fundamental defense strategy to find against multidrug resistance. Peptide combinations and conjugations with themselves or other molecules could effectively avoid the disadvantages of individual compounds, enhancing antibacterial activity, delivery efficiency and selectivity whilst introducing new functionalities.
