The purpose of the pH- triggered drug release is to deliver the drug precisely to the area of the tumor and not activate and release the drug in healthy tissue. [1] The complex compromises a drug delivery unit made up of a carrier molecule made up of organic nanomaterials, inorganic nanomaterials, composite nanomaterials, and anti-tumor drugs.
The majority of drugs used in cancer chemotherapy are cytostatic, many via cytotoxicity. A fundamental philosophy of medical oncology, including combination chemotherapy, is that different drugs work through different mechanisms, and that the results of using multiple drugs will be synergistic to some extent.
The blood brain barrier (BBB) has historically proved to be a very difficult obstacle to overcome when aiming to deliver a drug to the brain. In order to overcome the difficulties in delivering therapeutic levels of drug past the BBB, drugs had to either be lipophilic molecules with a molecular weight below 600 Da or be transported across the BBB using some sort of cellular transport system.

Big pharmaceutical companies that make personalized blood cancer treatments are working to cut the manufacturing turnaround time by as much as half in coming years, as they try to deliver them ...
To counteract this they then signal for new blood vessels to grow. The newly formed tumor vasculature is poorly formed and does not deliver an adequate blood supply to all areas of the tumor. This leads to issues with drug delivery because many drugs will be delivered to the tumor by the circulatory system. [143]
Drug delivery systems have been around for many years, but there are a few recent applications of drug delivery that warrant 1. Drug delivery to the brain: Many drugs can be harmful when administered systemically; the brain is very sensitive to medications and can easily cause damage if a drug is administered directly into the bloodstream.
Patients and their diseases are profiled in order to identify the most effective treatment for their specific case. Targeted therapy or molecularly targeted therapy is one of the major modalities of medical treatment (pharmacotherapy) for cancer, [1] others being hormonal therapy and cytotoxic chemotherapy.
Most alternative cancer treatments have not been tested in proper clinical trials. Among studies that have been published, the quality is often poor. A 2006 review of 196 clinical trials that studied unconventional cancer treatments found a lack of early-phase testing, little rationale for dosing regimens, and poor statistical analyses. [11]
