A breath tracking method based on a thermal imaging technology presented by the invention mainly includes optimal quantization for a high-heat dynamic range scene, nasal region tracking, and breath estimation through heat voxel integration. First, the heat distribution sequence is optimally quantized by searching for a heat range of interest containing the temperature distribution of the overall face in each frame. Then, the heat distribution sequence is compared with a normal heat image under combined artifacts to get different shapes of the nostrils from an image based on heat gradient, and feature points representing the moving track of the nostrils are collected using a converted image. Finally, features are extracted by calculating the average value of heat distribution in a bounding box, and breath estimation is carried out through heat voxel integration. A thermal imaging system presented by the invention is not affected by lighting conditions, and the accuracy and stability of the nostril area tracking are improved. Moreover, the thermal imaging technology is of low cost, and a new possibility is opened up for a breathing rate monitoring device based on a smart phone.

Dry powder formulations of drugs such as antihistamine for nasal administration are provided where the drug is retained in the nasal cavity, and systemic side effects minimized or eliminated, through the selection of a narrow particle size range, between approximately 10 and 20 microns in diameter. In a preferred embodiment wherein the drug is an antihistamine, retention of the antihistamine at the nasal mucosa is improved and the bitter aftertaste associated with liquid antihistamine formulations significantly reduced. By making a dry powder formulation of an antihistamine (e.g., azelastine) having an average particle size of between 10 and 20 microns, the antihistamine is restricted primarily to the desired target organ, the nasal mucosa. Because the active ingredient stays in the nasal region, a lower dose can be used to achieve the same desired effect. As demonstrated by the examples, this lower dose reduces the incidence of somnolence, and because the active ingredient remains at the target organ and does not accumulate in the back of the throat and mouth, this formulation does not impart a bitter taste.
