A 2014 study found that guaifenesin does not affect sputum volume in upper respiratory infections (the upper respiratory system includes most breathing parts above the lungs). [5] [6] Side effects may include dizziness, sleepiness, skin rash, and nausea. [4] While it has not been properly studied in pregnancy, it appears to be safe. [7]
An expectorant (from the Latin expectorare, to expel or banish) works by signaling the body to increase the amount or hydration of secretions, resulting in more, yet clearer, secretions and lubricating the irritated respiratory tract. [4] One mucoactive agent, guaifenesin, has anxiolytic and muscle-relaxing properties. It is commonly available ...
Guaifenesin is an oral medication used to try to help cough out phlegm from the airways. [1] It is often used in combination with other medications. [1] It is believed to work by making airway secretions more liquid. [1] Side effects may include dizziness, sleepiness, skin rash, and nausea. [2] Guaifenesin has been used medically since at least ...
Pulmonary drug delivery is mainly utilized for topical applications in the lungs, such as the use of inhaled beta-agonists, corticosteroids and anticholinergic agents for the treatment of asthma and COPD, the use of inhaled mucolytics and antibiotics for the treatment of cystic fibrosis (CT) and respiratory viral infections, [1] and the use of inhaled prostacyclin analogs for the treatment of ...
Chronic bronchitis is a lower respiratory tract disease, [26] defined by a productive cough that lasts for three months or more per year for at least two years. [1] [10] The cough is sometimes referred to as a smoker's cough since it often results from smoking.
Guaifenesin/codeine is a fixed-dose combination cold medicine used for the treatment of cough. [1] It contains guaifenesin, an expectorant; and codeine, as the phosphate, an opioid antitussive. [1] It is taken by mouth. [1] It was approved for medical use in the United States in 2006. [1]
Cold medicines are a group of medications taken individually or in combination as a treatment for the symptoms of the common cold and similar conditions of the upper respiratory tract. The term encompasses a broad array of drugs, including analgesics , antihistamines and decongestants , among many others.
Recall that the relationship represented in a Davenport diagram is a relationship between three variables: P CO 2, bicarbonate concentration and pH.Thus, Fig. 7 can be thought of as a topographical map—that is, a two-dimensional representation of a three-dimensional surface—where each isopleth indicates a different partial pressure or “altitude.”
