In commercials for inhalers containing salmeterol, there is often a warning that it can increase the risk of asthma-related death. Why is this true and how does it happen? Why is this warning heard in commercials for all medications containing salmeterol? What patient education is necessary when prescribing salmeterol inhalers?

Expert Solution

Salmeterol is a selective ADRENERGIC BETA-2 RECEPTOR agonist that functions as a bronchodilator when administered by inhalation. It is used to manage the symptoms of asthma and COPD. Increased brain-derived neurotrophic factor(BDNF) concentrations may underly the adverse effects of salmeterol monotherapy on airway responsiveness in asthma.BDNF may act as a mediator between airway inflammatory events and neuronal changes that occur during the induction of allergic asthma by enhancing airway smooth muscle contraction and mucus hypersecretion by facilitating the release of acetyl choline and plasma extravasation .(Siresha Bathina and Undurti N. Das 2015 )https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4697050/)BDNF is increased because of inhalation of salmetrol.

Patient education:

1.If a dose is missed ,skip it and continue regular dosing schedule .

2.Donot share your drugs with others,also donot use other person drug and keep out of reach of children.

Feminized faces in TV commercials. Television commercials most often employ females or “feminized” males to pitch a company’s product. Research published in Nature (August 27 1998) revealed that people are, in fact, more attracted to “feminized” faces, regardless of gender. In one experiment, 50 human subjects viewed both a Japanese female face and a Caucasian male face on a computer. Using special computer graphics, each subject could morph the faces (by making them more feminine or more masculine) until they...

Mortgage loan commercials and bank banners can be a little confusing due to the fact they report two rates: 1) the stated nominal annual rate that we usually think of as APR which is compounded monthly and is the rate that is used on the actual loan amount to determine the monthly payment, and 2) the "APR" which is somewhat higher and in some ads significantly higher than the first rate. This second "APR" is a stated nominal annual rate...
