This doc delivers an overview of huge and little quantity parenteral preparations. It begins with definitions of parenteral preparations and routes of administration. Advantages and disadvantages in the parenteral route are talked over. General necessities for parenteral dosage forms like containers, glass varieties, closures, and aseptic parts are covered.
This doc gives an summary of protein and peptide drug delivery. It commences with definitions of proteins and peptides and descriptions of protein framework. It then discusses protein functions and challenges with providing proteins and peptides. These problems include things like low permeability, enzyme degradation, limited half-lifetime, and immunogenicity. The document outlines numerous barriers to protein delivery, like enzymatic obstacles and limitations at the intestinal epithelium, capillary endothelium, and blood-Mind barrier.
It then addresses topics like continuous condition principles, diffusion mechanisms, dissolution models and polymer characterization as they relate to sustained and controlled release drug delivery. Analysis techniques for sustained release and controlled release tablets are also talked about.
Lozenges are usually useful for neighborhood gradual release of demulcents, anaesthetics and cough cures inside the mouth/pharynx. Supplements are solid unit dosage varieties made by compressing API with adhesives along with other excipients into rounded masses for oral administration.
