Aminophylline poisoning usually occurs within a few hours and does not usually occur after more than 12 hours of use.
Aminophylline poisoning is also a toxic reaction that occurs when too large a dose or too high a concentration of the drug is used.
Due to the use of aminophylline in different ways, the drug’s blood concentration peak time will also have certain changes, so the use of aminophylline poisoning symptoms will also have certain differences in time, such as oral aminophylline on an empty stomach, the peak blood concentration can be reached in 2 hours, which is also the time of the drug poisoning symptoms.
As the drug is metabolized and excreted from the body, the blood concentration of the drug gradually decreases, and the symptoms of poisoning will gradually improve or even disappear. Generally, after 12 hours, the drug has been metabolized, and the symptoms of poisoning will not reappear.
Since there are some individual differences in drug treatment, the specific situation needs to be analyzed by a doctor in consultation with your own situation.
