Abstract Combinations of more than two drugs are routinely used for the treatment of pathogens and tumors. High-order combinations may be chosen due to their non-overlapping resistance mechanisms or for favorable drug interactions. Synergistic/antagonistic interactions occur when the combination has a higher/lower effect than the sum of individual drug effects. https://www.bekindtopets.com/super-value-Blue-Lotion-Topical-Antiseptic-16-oz-flash-save/
