Fold the pharmacological
The chemical structure of this product is similar to that of isopropyl adrenalin, which is comparable to the norepinephrine.It is slowly absorbed in the trachea and is not easily damaged by sulfuric acid in the body, so it has a strong and persistent effect.This product effectively inhibits histamine and the release of allergenic delayed response substances to prevent bronchospasm.
Albuterol is a selective beta 2 agonist, which selectively excites the beta-2 receptors of the bronchosmooth muscle and has a strong bronchial dilation.In asthmatics, the bronchodilatation is at least equal to isopropyl.The release of anaphylaxis in cells such as mast cells is also associated with the anticonvulsive action of the bronchial smooth muscle.
The effect of this product on the beta 1 receptor in the heart was weaker, so it increased the rate of the heart rate with only one tenth of the epinephrine.This product is effective and lasts longer because it is not easily damaged by the enzymatic enzyme in the digestive tract and the catechol-oxygen in the tissue.Oral bioavailability is 30 per cent, taking 15 to 30 minutes after serving, and 2 ~ 4 hours at peak, lasting more than 6 hours.The bioavailability of air inhalation is 10%, effective in 1-5 minutes after inhalation, and 1 hour effect peak, lasting 4 ~ 6 hours.Vd is 1 l/kg.Most of them are metabolized in the gut wall and liver, with less than 20% of the original drugs in circulation.It is mainly excreted by the kidney.Bronchospasm in patients with bronchial asthma, asthmatic bronchitis and emphysema.To stop the inhalation of inhalation, the prevention of attack can be taken orally.
