general precautions the test is carried out under conditions limiting particu- late matter, preferably in a laminar flow cabinet. the tests described herein are physical tests performed for the purpose of enumerating extraneous particles within specific size ranges. the above description of usp < 788>. 788 particulate matter in injections. general chapters: < 788> particulate matter in injections. light obscuration and microscopic procedures for the determination of particulate matter in ophthalmic solutions are identical to those for injections; therefore, where appropriate, particulate matter in injections 788 is cross- referenced. pdf those for injections; therefore, where appropriate, particulate matter in injections 788 is cross- referenced. particulate matter in injections and parenteral infusions consists of mobile undissolved particles, other than gas bubbles, unintentionally present in the solutions. course description: this webinar series will update you on the latest usp developments in particulate matters. usp particle count rs. sensor resolution. usp < 789> strictly limits subvisible particles in ophthalmic solutions. here is a summary of how to test a sample following the new usp < 787> procedure: follow the same standardization steps as described in usp < 1788> : volume accuracy. request further information. this chapter can be used as an alternative to usp general chapter particulate matter in injections 〈 788〉. all intraocular solutions should be essentially free from particles that can be observed on visual inspection using visible particulates in injections 〈 790〉, as directed by ophthalmic products— quality tests 〈 771〉. view supplier profile. very carefully wash the glassware and filtration equip- ment used, except for the membrane filters, with a warm detergent solution, and rinse with abundant amounts of. this test applies to ophthalmic solutions, including solu- tions constituted from sterile solids, for which a test for par- ticulate matter is specified in the individual monograph. usp general chapters 1, 790, and 1790 subvisible particles: usp general chapters 787, pdf 788, 1787, and 1788 quality solutions relevant general chapters reference standard all the particulars on particles: usp on- demand webinars on particulate matter official documentary standards and materials particle count set ( 2 blanks and 2 suspensions. this general chapter provides an overview for the use of two procedures; method 1, light obscuration particle count test, and method ii, microscopic particle count test. ophthalmic solutions 〈 789〉. 789〉 particulate matter in ophthalmic solutions. for the determination of particulate matter, two procedures, method 1 ( light obscuration particle count test) and method 2 ( microscopic particle count test), are specified. usp < 789>, particulate matter in ophthalmic solutions — this test is different than the previous three because the particles being measured are the drug product ( an emulsion), not contamination. ophthalmic solutions should be essentially free from particles that can be observed on visual inspection. the usp < 789> particulate matter in ophthalmic solutions test is used to quantify the count and size of subvisible particles in eye care products. this webinar will focus on usp general chapter < 771> and the applicability of usp’ s visible ( < 790> ) and subvisible ( < 788> and < 789> ) standards to ophthalmic drug products. 3 defect prevention. light obscuration and microscopic procedures for the determination of particulate matter in ophthalmic solutions are identical to. the test counts suspended particles that are solid or liquid. 787〉 subvisible particulate matter in therapeutic protein injections. the usp < 789> is similar to the european pharmacopeia ch. 94 monograph are required to meet the applicable criteria from these usp general chapters ( see 95 section 501( b) of the fd& c act). sponsored content by entegris, inc. particulate matter consists of mobile, randomly- sourced, extraneous substances, other than gas bubbles, that cannot be quantitated by chemical analysis due to the small amount of material that it represents and to its heterogeneous composition. in may, a revision to usp< 1788> methods for determination of subvisible particulate matter was published, its aim is to aid in clarification and support of the information given in chapters < 788> particulate matter in injections, < 789> particulate matter in ophthalmic solutions, and < 787> sub- visible particulate matter usp 789 pdf in therapeutic. overview of the united states pharmacopeia chapters 787, 788, & 789 that address the particulate matter and testing on injectables. this chapter provides a test approach in two stages. light obscuration and in some cases microscopic membrane are used to identify particles and their respective sizes. as directed for light obscuration particle count test under particulate matter in injections á788ñ. in order to quantify the. download pdf copy. noncompendial products should also be “ essentially free from. — usp 789 pdf usp < 787> is meant for therapeutic protein injections, making changes for smaller test product volumes and smaller test aliquots. why particulate matter in ophthalmic solutions? the test calls for using a light obscuration particle counter and counting particles on a filter by microscopy. the critical size characteristics of lipid injectable emulsions include. background and objective( s) : usp guidance for particulate matter content is comprehensively addressed in the following general chapters: < 1> injections; < 787> particulate matter determination for therapeutic proteins; < 788> particulate matter determination for injections; < 789>. the usp < 788> particulate matter in injections general chapter is used to determine the count and size of undissolved particles in injection solutions ≥ 10 and ≥ 25 µm. measurement of subvisible particulate matter in therapeutic protein injections 〈 1787〉 and methods for the determination of particulate matter in injections and ophthalmic solutions 〈 1788〉 provide additional supporting information on measurement methods for subvisible particles.
