A Beacon for Gynaecological Cancers Patients: pH-Sensitive Nano medicine
Emergence of various Nano scale drug carrier platforms as Drug Delivery Systems (DDS) has revolutionized the field of medicine. Nonetheless, the side-effects due to non-specific distribution of anticancer therapeutics in normal, healthy tissues remain to be a prime pitfall in curing cancers. Therefore, to achieve a better therapeutic efficacy, the use of a target-specific delivery, combined with a stimuli-responsive Nano carrier system, particularly pH-sensitive Nano systems offer an attractive strategy. Targeted drug delivery through pH-sensitive Nano systems offer the potential to enhance the therapeutic index of anticancer agents, either by increasing the drug concentration in tumour cells and/or by decreasing the exposure in normal host tissues. Therefore, Nano scale-based drug delivery through pH-sensitive Nano systems seem to be a boon for treating gynaecological cancers (as well as other cancers) without side-effects or with least harm to normal healthy tissues.
