The stability of the rituximab biosimilar CT-P10, in 50mL vials at a concentration of 10mg/mL, and after dilution to final concentrations of 1 and 4mg/mL and storage in polyolefin bags at 4°C and 25°C was studied by several orthogonal and complementary methods. No significant change (as defined by a magnitude greater than the inter-batch variability) was observed, for each of the parameters characterizing physical and chemical stability studied, for the two concentrations and temperatures tested, or for any of the three batches tested. This implies that cold-chain rupture and exposure to room temperature up to 15 days both for vials and diluted bags have no deleterious consequence on the quality of the product. Moreover, this extended stability permits safe in-advance preparation, dose-banding or flat-dose, that to avoid unnecessary delays in the management of the patient, improvement of the pharmacy and nurse workload and money saving by avoiding non justified losses of this expensive drug.

Drug Product Stability

The long-term stability of drug products is critical to ensuring their quality, safety, and effectiveness over time. Stability directly influences a product's ability to maintain its intended characteristics, ensuring it performs as expected during its intended shelf life. Key attributes such as drug potency, impurities, dissolution, and other physicochemical measures of performance are tested to assess stability. These parameters indicate how well the product retains its quality over time and...

Bioavailability Enhancement: Drug Stability Enhancement and GI Retention

Body:Improving a drug's stability in the gastrointestinal (GI) tract is paramount for enhancing its bioavailability and therapeutic effectiveness. Various strategies are employed to protect the drug from the harsh gastric milieu and to ensure its release and absorption at the desired site within the GI tract.Polymer coatings are one such method used to shield drugs from the stomach's acidic environment. By preventing premature drug release, these coatings improve the bioavailability of unstable...

Generic intravenous (IV) drugs are considered bioequivalent to their branded counterparts due to their 100% bioavailability upon administration. However, variations in stability among different drug products can significantly influence their therapeutic performance, even if they are pharmaceutically equivalent.Cefuroxime, a prophylactic antimicrobial, is often used as a single-dose IV injection for patients undergoing coronary artery bypass grafting surgery.

Modified-Release Drug Delivery Systems: Bioavailability

Modified-release (MR) dosage forms are designed to extend drug release over time, thereby maintaining stable plasma concentrations and reducing dosing frequency. However, their bioavailability is typically below 100% due to incomplete drug release and presystemic metabolism, and limitations in drug permeability across the gastrointestinal epithelium, all of which can restrict the fraction of the drug reaching systemic circulation. Consequently, studying the in vivo bioavailability of MR...
