Q

Albuterol

Mechanism of Action

A

Causes bronchodilation by action on beta2 (pulmonary) receptors by increasing levels of cAMP, which relaxes smooth muscle; produces bronchodilation, CNS, cardiac stimulation as well as increased diuresis and gastric acid secretion; longer acting than isoproterenol

Q

Albuterol

Nursing Considerations

A

ASSESS:

  • Respiratory function: vital capacity, forced expiratory volume, ABGs; lung sounds, heart rate and rhythm, BP, sputum (baseline and peak); whether patient has not received theophylline therapy before giving dose
  • Patient’s ability to self-medicate
  • For evidence of allergic reactions
  • For paradoxical bronchospasm; hold medication, notify prescriber if bronchospasm occurs

Q

Montelukast (Singulair)

Mechanism of Action

A

Inhibits leukotriene (LTD4) formation; leukotrienes exert their effects by increasing neutrophil, eosinophil migraine; aggregation of neutrophils, monocytes; smooth muscle contraction, capillary permeability; these actions further lead to bronchoconstriction, inflammation, edema

Q

Salmeterol (Serevent)

Mechanism of Action

A

Causes bronchodilation by action on beta2 (pulmonary) receptors by increasing levels of cAMP, which relaxes smooth muscle with very little effect on heart rate; maintains improvement in FEV from 3 to 12hr; prevents nocturnal asthma symptoms
