A dual-drug delivery system is proposed for improving chemotherapy efficacy and relieving pain associated with colorectal cancer. This system utilizes hydrogels to protect drugs and achieve dual pH-responsive drug delivery. The findings have significant implications for medical science and pharmaceutics.
To improve the efficacy of chemotherapy and relieve the pain associated with colorectal cancer, a dual-drug delivery system (DDDS) is proposed. In this system, methotrexate (MTX) loaded CaCO3 (CaCO3/MTX) and aspirin (Asp) are co-entrapped in the hydrogels of alginate (Alg) and sodium carboxymethyl cellulose (CMC) crosslinked with Ca2+. The hydrogels can protect the anti-cancer drug of MTX from being absorbed in stomach and small intestine and ensure their efficacy at the target site of colorectum. More importantly, dual pHresponsive drug delivery can be achieved by the DDDS. Because the pH varies at small intestine and colorectum of human body, dual pH-responsive delivery of Asp and MTX can be achieved at the two organs, respectively, in response to ambient pH. These finding are of significant importance for medical science and pharmaceutics.
