Route of administration

mainlyOral administrationとParenteral administrationIt is divided into

Oral administration

  • Oral administration
  • Sublingual administration

な ど

In the case of oral administration, by the time the pharmacological substance reaches the circulating blood from the oral mucosa, stomach wall, intestinal wall, etc., the administered tablet is dissolved (due to changes in fat solubility), absorbed into the blood through membrane absorption, and then taken into the affected area. Sent.However, blood containing substances absorbed from the intestinal wall is first sent to the liver and is therefore affected by metabolism.The liver has a high metabolic capacity, and the pharmacological substances are metabolized in the liver by the time they reach the affected area.First pass effectCalled.The ratio of the amount of the administered pharmacological substance taken into the circulating blood in the bodyBioavailabilityHowever, oral administration generally has low bioavailability due to the first-pass effect, etc., and even if the same amount is administered, the absorption site and absorption amount in the body are likely to vary from the initial assumption. turn into.
