Final answer:
Nanotechnology-based drug delivery systems offer enhanced stability and therapeutic efficacy. These systems can co-deliver multiple drugs and achieve targeted release, improving treatment outcomes.
Step-by-step explanation:
The most stable formulation in drug delivery can vary depending on the specific drug and the desired therapeutic outcome. However, nanotechnology has emerged as a promising approach to improve stability and effectiveness of drug delivery systems.
One example is the use of nanoparticulate systems that combine different drug molecules or therapeutic classes to enhance their stability and efficacy. These nanosystems can be designed to co-deliver multiple drugs, such as siRNA and doxorubicin, in a targeted and controlled manner.
