The active pharmaceutical ingredient, or api, is the main ingredient that does most of the medical work.It is the essential ingredient in the inhaler.Apis are best processed using the fluidized bed opposed jet mill or the spiral jet mill.This is because these mills have the capacity to ensure that the particles that are ground are the.
The cojet milled formulations once again exhibited exceptional fpfs when it is dispensed using an active dry powder inhaler device.The improvement appears to be largely due to reduced throat deposition which was less than 5, compared to between 16 and 29 for the mechanofused formulations.12a was produced as a repeat of 10a, but.
Drypowder inhaler formulations typically comprise a combination of a carrier substance with the active pharmaceutical ingredient api.Sometimes additives are required to enhance the product properties, such as flowability, or to support the mechanical bonding of carrier with api.The carrier material, often lactose, repre.
The overall aim of this research project was to investigate the aerosol performance and physicochemical properties of dry powder formulations produced by comilling an active pharmaceutical ingredient api beclomethasone dipropionate bdp with an additive magnesium stearate mgst, using the jet mill apparatus, for high dose delivery.

Different dry powder inhalation devices are available in the market, yet no single inhaler device possesses all the properties of an ideal inhaler.Dry powder inhalers are devices which store the medication as fine particle aggregates, either as a pure drug substance or encapsulated in a nano or microparticulate formulation.
Introduction.Dry powder inhalers dpi are the preferred devices among orally inhaled drug products due to their ease of handling and administration as well as superior product stability 1.They deliver a dry powder of the active pharmaceutical ingredient api either in the presence or absence of larger size excipient particles usually a sugar as the carrier.
