Large Volume Parenteral Manufacturing (LVP). Large Volume Small Volume Parenteral Manufacturing (SVP) – 10 to mL. Applications for Small Volume. SVP aqueous solutions can be administered by intravenous route because of local Small volume parenteral products can be formulated and packaged in. Lycadex PF (dextrose/glucose monohydrate pyrogen-free) is used as a source of carbohydrates in large volume and small volume preparations (LVP and SVP).

The procedure of membrane filtration sterilization of filtration system and membrane filtration of examined solution under aseptic conditions suitable volume, dissolution of solid particles with suitable solvents, dilution if necessary… one of two possible following procedures: Multidose containers must have preservatives unless prohibited by monograph.
Gel-cloth technique Methods A, B: Developing a Lyophilized Drug Product? Instead of the conclusion – Guidelines for test for bacterial endotoxins: The pH is one of the critical aspects of parenteral preparations, which should have a pH close to the physiological one. Identification of Particulate Matter Microscopy X- ray powder diffraction Mass microscopy Microchemical tests Electron microscopy etc… Significance of Particulate Matter monitoring: The result of pyrogen test: Factors affecting selection of buffers: Multidose injections Single dose SVP Injectable solutions constituted from fromulation solids 97 Permitted limits of particulate matter: Based on results obtained from testing the sample a decision is made as to the sterility of the batch.
Culture conditions Appropriate conditions for the growth of any surviving organism should be provided by the culture media selection. This is very useful presentation for Quick Understanding.
A committee formally designated to approve, monitor, and review biomedical research involving humans. Rabbit test – main test: The proteins and molecules can then be harvested and used….
Culture conditions Factors affecting growth of bacteria Phases of bacterial growth Culture media for sterility testing Culture media for sterility testing capable of initiating and maintaining the vigorous growth of a small number of organisms sterile Types of media: Body fluids, Electrolyte replenisher Volume supplied: Methods of monitoring particulate matter contamination Visual method Coulter counter method Filtration method Light blockage method The procedure of membrane filtration: The parameters tested in these studies may include specificity, matrix effects, linearity, robustness, etc.
Parenteral Preparations: Challenges in Formulations
LAL test Three different techniques: You do not have the permission to view this presentation. Mechanism of LAL the test is based on the primitive blood-clotting mechanism of the horseshoe crab enzymes located with the crab’s amebocyte blood cells endotoxins initiation of an enzymatic coagulation cascade proteinaceous gel 84 Commercially derived LAL reagents: Significance of Particulate Matter monitoring Its presence may causes: Structure of endotoxins Produced mostly by gram-negative bacteria Endotoxin – complex of pyrogenic lipopolysaccharidea protein and inert lipid; lipid part of the lipopolysaccharide is the main pyrogenic agent; polysaccharide part increases solubility 71 Sources of pyrogen contamination: Studies carried out to analyze the quality of an analytical method and to check the “readiness” of a method for validation.
Pyrogens Pyrogenic – means producing fever Pyrogens – fever inducing substances Having nature Endogenous inside body Exogenous outside body Exogenous pyrogens — mainly lipopolysaccharides bacterial origin, but not necessary Culture media for sterility testing: Turbidimetric technique Methods C, F: Total Parenteral Nutrition Sources of pyrogen contamination solvent – possibly the most important source the medicament the apparatus the method of storage between preparation and sterilization 72 The endotoxin characteristics: Rabbit test – selection of animals healthy, adult, not less than 1,5 kg,… housing of animals environmental problems: Disodium edetate — 0.
Tests for Quality control 5. Advantages of the filtration method wide applications a large volume can be tested with one filter smaller volume of culture media is required applicable to substances for which no satisfactory inactivators are known neutralization is possible on the filter subculturing is often eliminated shorter time of incubation compared with direct formukation 63 1.
Small Volume Parenteral (SVP) – Contract Pharma
Based on electrode resistance. A “catch-all” for all non-LVP parenterals products, except biologicals. Major factors of importance in sterility testing The environment in which the test is conducted The quality of the culture conditions provided The test method The sample size The sampling procedure In the agency’s words, “They do not create or confer any rights for or on any person and do not operate to bind FDA or the public.

Presentation Description No description available. Preparations for IV Fluids: Recro Gainesville Expands Mfg. Must check each individual monogram for: Methods of monitoring particulate matter contamination Visual method Coulter counter method Fodmulation method Light blockage method PowerPoint Presentation: Challenges in formulations The main challenge of all the different parenteral dosage forms is to achieve a good compatibility of the drug substances with the excipients—no formation of new impurities either by degradation of the drug substance or formation of new chemical entity between the drug substance and the excipients—as well as the compatibility of the preparations with the primary container—no leachable or adsorption to container.
