Bronchodilators

1.B2 agonist
Albuterol Levalbuterol Metaproterenol(alupent) Isoeltharine Terutaline(breathair) 2.nonselective Epinephrine(adrenalin) Iv or im 3. Methylaxnthines Theophylline Aminophylline 4.anticholinergics Ipratropium bromide |

Non selective sympathomimetics
|
Epinephrine
Effective bronchodilator. Also cause vasoconstriction. Decreased histamine effects Therefore less inflammation. |
Big gun
Big Side effects Big impact Last resort sympathetic nervous system response |

B2 selective sympathomimetics
|
Albuterol
Levalbuterol Metaproterenol(alupent) Isoeltharine Terutaline(breathair)-also dilates uterus |
beta2-adrenergic receptor, thereby causing smooth muscle relaxation, resulting in dilation of bronchial passages, vasodilation in muscle and liver, relaxation of uterine muscle, and release of insulin.

Basic bronchodilators
B2 specific |
Types of meds medsAlbuterol,levalbuterol, metaproterenol,isoetharine, terdutaline
Class:sympathomimetic (relatively beta2 specific) Indications:Bronchospasms associated with asthma COPD bronchitis,near drowning, drug overdose, pulmonary edema, etc. Side effects: anxiety(and symptoms) burn, chest pain, headache, nausea Precautions: pt w/ cardiac history severe & hypertension; Monitor for dysrhythmia Interactions: epi & other sympathomatics may 10 suffice side effects of albuterol Roots of administration: Nebulized;usually prepackaged of 2.5 MG in 3 ML NaCL Onset:5-15 mins Duration: 3-4hr |

Class : sympathomimetic bronchodilator
Indications: croup, bronchospasm Side effects: anxiety,nausea and v, high bp, angina, headache, dizziness Contraindications: epiglottitis Precautions: elderly , patients with cardiac history,& monitor closely for dysrhythmias Routes: nebulized Onset: 3-5 mins Duration: 1-3 hrs |

Basic bronchodilators
(Epi) adrenaline |
Class: sympathomimetic, vasopressor, bronchodilator
Indication: cardiac arrest, anaphylaxis or severe allergic reaction, severe reactive airway disease( asthma, COPD) also shocker hypertension and Extreme bradycardia( only with peds) Mechanism of action:acts directly on alpha and beta receptors of the sympathetic nervous system(sns). Ronquille smooth muscle dilation other things. Side effects: Contraindication: hypertension, hypovolemia;no contraindications and cardiac arrest( here we Dgaf) Precaution: Will increase myocardial oxygen demand;hey increase ischemia;caution with underlining cardiovascular disease and pregnancy Interactions: Epi is PH dependent and can be inactivated by alkaline solution(sodium bicarbonate) Routes:IV IO IVPB IM SQ ET Onset:immediate Duration: 3-5min |
