This chapter will start off by looking at various routes of administration. Other pharmacokinetic challenges, for instance drug absorption, distribution, and storage, will then be resolved. Drug metabolism is going to be lined in the subsequent chapter.
The particle dimensions with the inhaled medication will likely be one to ten µm for helpful shipping and delivery. The efficacy of drug delivery into the lungs depends not simply over the drug particle measurement and morphology but will also about the client's respiratory physiology, for example tidal volume and tracheal inspiration velocity.[four]
