An aerosol formulation containing 7.5 mg of R-salbutamol sulfate was developed. The aerosol was nebulized with an air-jet nebulizer, and further assessed according to the new European Medicines Agency (EMA) guidelines. A breath simulator was used for studies of delivery rate and total amount of the active ingredient at volume of 3 mL. A next generation impactor (NGI) with a cooler was used for ...

Four commercially available medicinal aerosol products in India have been assessed for the aerosol size distribution at two different humidities using a ten stage cascape impactor device having a quartz crystal microbalance system. An indigenously made nebulizer in use in a city hospital has also been assessed for its aerosol efficiency. The size range is between 0.05 and 25 J.l,m. Mode in the ...

Corticosteroid (budesonide) nebulizer therapy is commonly performed. Its side effects have been considered as being safe or ignorable. The authors present a case of esophageal candidiasis in a healthy female adolescent who was treated with budesonide nebulizer therapy a few times for a cough during the previous winter season. This child presented with dysphagia and epigastric pain for 1 month. ...

Objectives: Many healthcare workers and patients in intensive care units of Sardjito Hospital, a referral academic hospital Yogyakarta, Indonesia, were infected with SARS-CoV-2 June–August 2021, during the second wave COVID-19 pandemic. Much evidence has shown that persists on environmental surfaces medical equipment. We investigated potential sources virus our cases, particularly contamination...

Ten new jet nebulizers (DeVilbiss 646) were studied to determine their consistency of output. Each nebulizer, containing 2 ml of saline solution, was run for 1 min in triplicate at four different straw (capillary tube) positions, keeping all other variables constant. Total output in milliliters per minute and volume of aerosol in the respirable range (1.0 to 5.0 microns) were measured. There wa...

A direct method was developed to determine the viability of a freshly generated mixed bacterial aerosol. A mixed suspension of (32)P-labeled Staphylococcus aureus and (35)S-labeled Proteus mirabilis was nebulized, and the aerosol was collected and separated according to particle size with an Andersen sampler. Quantitative and qualitative bacteriological and radioisotopic techniques were used to...

In this flow-injection system for direct determination of lithium in serum by atomic absorption spectroscopy, the 10-microL sample is manually injected into a continuously flowing non-segmented stream of de-ionized water, which is pumped, via a dispersion tube, to the spectrometer's nebulizer. Controlled dispersion of the sample zone, before it is introduced into the nebulizer, produces the req...
