Respiratory system dyspnea

Adverse events involving the respiratory system (dyspnea, increased cough, or asthma) were reported in about 2% of patients taking dirithromycin (1). 

Headache, tachypnea, dizziness, confusion, and chest pain. The casualty may also experience palpitations, dyspnea on exertion, drowsiness, lethargy, hallucination, agitation, nausea, vomiting, diarrhea, and coma. If metal carbonyls have been released, there may be complaints of irritation of the eyes, mucous membrane, and respiratory system. Inflammation of lung tissue (pneumonitis) caused by metal carbonyls can may be delayed 12-36 hours. They may also cause injury to the liver, kidneys, and lungs as well as degenerative changes in the central nervous system. 

Colorless, water-white, or pale-yellow, oily liquid with a mild, skunk-like odor detectable at 0.5 ppm. This material is hazardous through inhalation and ingestion, and produces local skin/eye impacts. It causes irritation to the eyes, skin, respiratory system cough dizziness, dyspnea (breathing difficulty), lassitude (weakness, exhaustion), confusion, cyanosis abdominal pain, nausea skin sensitization. 

Symptoms of exposure May cause weakness, confusion, depression of central nervous system, dyspnea, weak pulse, and respiratory failure. May irritate eyes and mucous membranes. Contact with skin may cause burns and dermatitis. Chronic effects may include gastrointestinal disorders, nervous disorders, tremor, confusion, skin eruptions, oliguria, jaundice, and liver damage (NIOSH, 1997 Patnaik, 1992). 

Most of the chemicals in Table 11.2 target the respiratory system and CNS. Exposures in arts and crafts use are almost always to mixtures of lipophilic and hydrophilic chemicals. When used in areas with poor air circulation (as is often the case in home use) the result can be unexpected acute toxicity. For example, it has been reported that exposure to formaldehyde and terpene hydrocarbons at very low levels unexpectedly produced dyspnea and other lower-lung symptoms in wood workers. The effects could not be attributed to either the formaldehyde or the terpenes alone at low levels of exposure In another example, it was reported that chronic exposure to a combination of very low concentrations of MEK, ethyl acetate, and aliphatic hydrocarbons in a leather adhesive formulation induced unanticipated CNS effects. Some products that are considered by most... 

Onset is rapid and the eyes and respiratory system are most affected. Low-level exposure causes tightness of the chest, rhinorrhea and salivation. Dimming of vision due to miosis, eye pain and headache then follow. On examination, the pupils are constricted and the conjunctivae hyperaemic. These effects may last several hours after cessation of exposure and the headache and visual problems several days. In severe cases, salivation and rhinorrhea are more marked, and wheezing and dyspnea are prominent. Other effects, such as abdominal pain, vomiting, involuntary defecation and micturition, weakness, fasciculation and convulsion, follow depending on the degree of systemic absorption. Death may occur from respiratory failure. 

Regardless of their subclassification, all of these compounds have the identical mechanism of action, which is inhibition of acetylcholinesterase at nerve junctions where the molecule acetylcholine is the neuotransmitter. Most acute signs of toxicity are expressed as uncontrollable activity of the nervous system, which clinically is presented as salivation, lacrimation, urination, defecation, and dyspnea. After lethal doses, death results from failure of the respiratory system. Variations in the specific nerves affected, in how the body metabolizes the individual chemical, in where the chemical enters the body, and in the route of administration employed will change the specific clinical presentation seen for an individual exposure scenario.
