Biomedical Applications of Biodegradable Polymers in Wound Care
According to the World Health Organization, it is estimated that 180,000 deaths occur annually due to burns. In the United States, it is expected that chronic wounds (e.g., diabetic and pressure ulcers) affect 6.5 million people. Thus, skin lesions are a public health problem that imposes the…

Role of release modifiers to modulate drug release from fused deposition modelling (FDM) 3D printed…
Although hot melt extrusion (HME) has been used in combination with fused deposition modelling (FDM) three-dimensional printing (3DP), suitable feedstock materials such as polymeric filaments with optimum properties are still limited. In this study, various release modifying excipients, namely,…

Influence of excipients in Protein a chromatography and virus inactivation
The purification of monoclonal antibodies and Fc fusion proteins consist of several unit operations operated commonly as a platform approach, starting with Protein A chromatography. The first capture step, the following low pH virus inactivation, and subsequent ion exchange chromatography steps are…

Mucoadhesive and mucus-penetrating Interpolyelectrolyte complexes for nose-to-brain drug delivery
Nasal administration offers a possibility of delivering drugs to the brain. In the present work, nasal drug delivery systems were designed based on cationic Eudragit® EPO (EPO) and anionic Eudragit® L100–55 (L100–55) methacrylate copolymers. Two types of nanocarriers were prepared using…

Effects of Different Capsule Types for Oral Application of Active Substances – Investigations with…
1.1. Background: A capsule is a solid dosage form that delivers a defined dose of an active ingredient. Most capsules are made for oral application by mouth with subsequent swallowing. Capsule materials for the shell are not only of importance for the release of active ingredients, but should also…

Three-dimensional printing of tablets – a potential approach to on-clinical-site extemporaneous…
The oral route is the most common form of drug administration, being a safe and convenient, particularly for solid oral dosage forms. Current large-scale manufacturing techniques mostly result in fixed dose units and allow a limited choice of dosage strengths. In some cases, there is a need for…

The Chronotopic™ System for Pulsatile and Colonic Delivery of Active Molecules in the Era of…
The pulsatile-release Chronotopic™ system was conceived of as a drug-containing core surrounded by a coat made of swellable/soluble hydrophilic polymers, the latter being able to provide a programmable lag phase prior to drug liberation. This system was also proposed in a colon-targeting…

Microwave-induced in situ drug amorphization using a mixture of polyethylene glycol and…
The use of a mixture of polyethylene glycol (PEG) and polyvinylpyrrolidone (PVP) was investigated for microwave-induced in situ amorphization of celecoxib (CCX) inside compacts. Such amorphization requires the presence of a dipolar excipient in the formulation to ensure heating of the compact by…
