Pharmacokinetics

Paracetamol is well absorbed inside the gastrointestinal tract after the use of drugs inside. Plasma Cmax values are noted after the 1st hour. The period of excretion of metabolic products of paracetamol is in the range of 1-4 hours. Basically this process is carried out by the kidneys. Half-life is 3 hours. This period can be prolonged in people with kidney or liver failure, as well as in connection with drug overdose.

Peak blood levels of theophylline are observed after 2.5 hours. Half-life is 11 hours.

After oral administration, atropine synthesizes 18% with blood protein. Approximately half of the portion used is excreted unchanged through the kidneys.

Ephedrine has good absorption inside the digestive system. Inside the plasma, the desired therapeutic values of the substance are maintained. Biotransformation of ephedrine occurs inside the liver. Excretion - mainly with urine.
