Open, Inhale, Close

Open, inhale, close has become the Holy Grail of inhaler designers – anything more demanding being considered likely to negatively influence a patient’s desire or ability to correctly use an inhaler device. Therefore, these three steps set in motion the processes needed to defeat the anatomical and physiological barriers in the lungs and nose for delivery of a drug to a local receptor or one in a remote organ. In short, the job of a pharmaceutical aerosol researcher is to overcome the complex chemical, physical, and biological barriers to drug efficacy using a device patients can and will use. The barriers go beyond science; regulations, cost, human nature, and personal experience all play a role in determining if a patient will indeed open, inhale, close. Not even 30-year veterans of Respiratory Drug Delivery (RDD®) meetings can single-handedly accumulate the vast range of knowledge, skills, and experience needed to develop an inhaled product. Pulmonary and nasal product development demands interdisciplinary collaboration and the active involvement of the patient.

Time lapse photography to demonstrate the potential antimicrobial abilities of Dycem contamination control flooring

Dycem

A defined volume of bioluminescent reporter bacteria was deposited onto 20 mm x 20 mm coupons of Dycem flooring, vinyl tile and ITW Alma tacky mat. Through monitoring of bacterial bioluminescence, metabolic inhibition was observed on all three surfaces however the effect occurred more rapidly on Dycem flooring than on vinyl or ITW Alma. Recovery counts after three hours of exposure to the floor surfaces showed between a 65% and 100% decrease in the number of viable organisms recovered from Dycem flooring compared to controls. On vinyl and ITW Alma flooring, there were slight increases in the number of viable survivors recovered compared to controls. Dycem flooring inhibited the metabolic activity and reduced the number of viable survivors recovered of Salmonella enterica Serovar Typhimurium DT104 pGLITE. It remains unclear as to whether this effect is attributable to the impregnated biocide or rapid drying of the inoculum on this surface.
