Nanosuspension consists of nanocrystals of poorly water soluble drug suspended in aqueous media and stabilized using minimal concentration of stabilizers. …
The suspension is pumped back into the milling chamber with a certain velocity and hence within a short residence time in the chamber, the particles are exposed to high energy input thereby reducing its particle size (Kwade, 1999). Planetary ball mills with modified sample holders are available for small-scale production of nanosuspension.
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 …
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 High Energy Ball Mill Emax combines high-frequency impact, intensive friction, and controlled circular jar movements to a unique and highly effective size reduction mechanism. The grinding jars have an oval shape and are mounted on two discs respectively which move the jars on a circular course without changing their orientation.
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 suspension manufacturing techniques are indeed considered, and the fabrication of such dosage form requires suspension aseptic ball milling; thereafter, the preparation is aseptically transferred into a hermetically sealed sterile container .
After the addition of CNC/A40 and the ball-milling process, a suspension with a low average particle size of 242.8 nm and a high zeta-potential of −61.3 mV was successfully formulated. Furthermore, β-TCP bone cement was made to show the applicability of this formulation, and it is bio-compatible with cell cultivation. ...
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.
Ophthalmic suspensions containing brinzolamide or brinzolamide and a beta-blocker and processes for manufacturing the suspensions are disclosed.
