Rezension

".a good foundation in chemistry is assumed, making this text most useful for science graduate students and scientists in the pharmaceutical industry. Students or newcomers to the field of drug stability should find the 'problem' section useful, with questions and answers based on real data provided." --PharmaceuticalJournal.com, July 18, 2014

".describes the stability of pharmaceutical products as the capacity of the product or a given drug substance to remain within established specifications of identity, potency, and purity during a specified time period.topics are principles of drug degradation, degradation pathways, drug degradation in semi-solid dosage forms." --ProtoView.com, April 2014

  • I. Principles of drug degradation (the solution kinetics and mathematical treatment):1. Zero, first, second and third order reactions2. Complex reactions (e.g. reversible reactions, parallel reactions, consecutive reactions, steady state, enzyme kinetics etc.)3. Effect of temperature (e.g. Arrhenius, Q10-values, Collision theory, Transition state theory, Eyring equation etc.)4. Effect of pH (Specific acid/base catalysis, pH-rate profiles)5. Effect of buffer salts (General acid/base catalysis or buffer catalysis)6. Ionic strength7. Solvent effects (e.g. dielectric constant)8. Surface active compounds (micelle effect)9. Effect of complexation (e.g. cyclodextrins, metal ions and carbohydrates)10. Effect of light, oxygen and other catalytic compounds.II. Degradation pathwaysSelected examples of drug degradation with examples and mathematical calculations.1. Hydrolysis (aspirin, procaine, procainamide, acetaminophen, ss-lactam antibiotics, nitrogen mustards etc.)2. Oxidation (morphine, epinephrine, vitamin C, vitamin A, hydrocortisone, polyunsaturated fatty acids (autoxidation) etc.; antioxidants)3. Isomerization and racemization (ephedrine, tetracyclines, pilocarpine, vitamin A, thalidomide, etc.)4. Photodegradation5. Polymerization (ss-lactam antibiotics etc.)6. Decarboxylation and elimination (p-aminosalicylic acid)7. Dehydration (prostaglandins etc.)III. Drug degradation in semi-solid state1. Ointments2. Creams (o/w and w/o emulsions)3. GelsIV. Drug degradation in solid state1. Physical stability of drugs (crystallization of amorphous drugs, polymorph transitions, crystal growth, moisture absorption and vapor absorption, nitroglycerine)2. Chemical stability (hydrolysis (aspirin), etc.)V. Stability of peptide and proteinsVI. Stability testing1. Stability testing during preformulation studies.2. Stability testing of the final product 3. Regulations of stability testing (including ICH guidelines)Appendix
