What ways do you know how to inject medicines into the body?
Medicinal substances are introduced into the human body in various ways. A practitioner is given the full right to inject drugs into the body in any known way.
The choice of the route of administration is dictated by the following three circumstances:
1. The patient's condition: the severity of the disease (in cases threatening the patient's life, fast-acting substances are introduced).
2. Properties of drugs (solubility, rate of development of the effect, duration of action).
3. Intuition, professional training of a doctor.
Traditionally, enteral and parenteral routes of drug administration into the body are distinguished.
Enteral routes of administration (through the gastrointestinal tract):
Oral (by mouth);
sublingual (under the tongue);
buccal ("gluing" to the mucous membrane of the cheeks, gums);
Duodenal (into the duodenum);
Rectal (into the rectum).
Parenteral routes of administration (ie bypassing the gastrointestinal tract): subcutaneous;
@benzol00 Do you know what the advantages of the enteral method have?
The advantages of the enteral route of administration are its convenience (no medical assistance is required), as well as comparative safety and the absence of complications typical for parenteral administration.
Many other routes of administration are known in pharmacy, for example, transdermal, intranasal, endosinusial, administration into the ear cavity, urethral, vaginal, intrauterine, intraarticular, intraosseous, administration into the cerebrospinal fluid, intrathecal administration, intraperitoneal, intracardiac administration, administration into the bladder, topical application to the eye, subconjunctival, parabulbar administration, intraocular administration, etc.
You can also use a microneedle patch. This replaces customary syringe injections.
