The influence of mechanical activation in a planetary ball mill on the change of the structure of BaTiO 3 powders has been investigated. The particle size distribution of the nonactivated and ...
Rapid advancement in drug discovery process is leading to a number of potential new drug candidates having excellent drug efficacy but limited aqueous solubility. By virtue of the submicron particle size and distinct …
Ophthalmic suspension demands that the particle size should be extremely small in order to avoid irritation on application. Smaller particle size also helps cover larger surface areas and quicker action. The desired particle size recommended is less than 10 micron. Aseptic ball milling of the final suspension is also not feasible.
The present invention relates to a process for manufacturing sterile Brinzolamide Ophthalmic Suspension. Specifically, the present invention relates to a process for manufacturing sterile ophthalmic suspension comprising Brinzolamide sterilized by Dry Heat Sterilization and pharmaceutical suspension obtained by using the said sterilized Brinzolamide.
Sterile, topical, ophthalmic suspensions have typically been manufactured in the past in one of three ways: by bulk sterilization of a milled suspension, by aseptic addition of sterile micronized raw material into a sterile vehicle, or by aseptic addition of a sterile raw material to a sterile menstruum followed by ball milling and aseptic ...
a. autoclaving a milling slurry comprising brinzolamide, milling beads, and a surfactant selected from the group consisting of tyloxapol and triton X-100; b. ball milling the …
Sterile, topical, ophthalmic suspensions have typically been manufactured in the past in one of three ways: by bulk sterilization of a milled suspension, by aseptic addition of sterile …
The manufacture of the suspension includes sterilization of the micronized active drug by dry heat, exposure to gamma radiation or ethylene oxide, or in some cases steam sterilization of the concentrated slurry followed by ball-milling (Ali et al. 2000). In general, key steps of manufacturing suspensions are (a) preparation of a dispersion of ...
The milling bottle and its ingredients were autoclaved on standard fast cool cycle. 6. The milling bottle was removed immediately after completion of the autoclave cycle and ball milling was begun at 50-55 RPM for 18-19 hours. 7. The milling slurry was then held for use in aseptic addition.
Process to manufacture Brinzolamide Ophthalmic Suspension has also been disclosed in prior art,US6071904. The aforementioned patent describes a process to manufacture Brinzolamide …

Sterile, topical, ophthalmic suspensions have typically been manufactured in the past in one of three ways: by bulk sterilization of a milled suspension, by aseptic addition of sterile micronized raw material into a sterile vehicle, or by aseptic addition of a sterile raw material to a sterile menstruum followed by ball milling and aseptic ...
These nanotechnology platforms generously evolved to overwhelm the troubles associated with the physiological barriers in the ocular route. The controlled-drug-formulation-based strategic …
Aseptic ball milling of the final suspension is also not feasible. This is due to unacceptable shear thinning of the polymer which occurs in the final milling step which affects the viscosity of the final suspension. Prior art also states that dry heat sterilization causes melting of the material. Sterilization by ethylene oxide introduces ...
The aforementioned patent describes a process to manufacture Brinzolamide suspension by autoclaving Brinzolamide and surfactant together followed by ball milling. This milled mixture is …
The media milling method was discovered by Liversidge et al. in 1992 . The most widely used is ball mills, which are used in the preparation of nanosuspensions by a grinding method, although jet mills or colloid mills are also used. The ball mill method can be expressed in different ways: bead milling, wet media milling, and pearl milling.
Aseptic ball milling of this final formulation is not practical. Aseptic addition of the CAI to a sterile vehicle is also not practical as the CAI cannot be sterilized by conventional means. ... Filter 12 prevents the suspension and the milling slurry from expanding out of carboy 11 during autoclaving, but allows for pressure equalization ...
