Injections refer to preparations prepared from sterile solutions (including emulsions and suspensions) of the drugs for injection into the body, sterile powders or concentrated solutions for constitution into solutions or suspensions just prior to use, in ampoules or in multi-dose containers. It is mainly determined according to the nature of the medicine and the requirements of medical treatment. Generally, water-soluble drugs are required to be quick-acting after injection, so they are often formulated into aqueous solutions or aqueous complex solutions (e.g., aqueous solutions with addition of ethanol, propylene glycol, glycerin, etc.). Some drugs should not be made into aqueous solution, such as oil solution, water or oil suspension, emulsion, etc., because they are difficult to dissolve in water or can prolong the drug effect after injection. However, these injections are generally given only for intramuscular injection.
The injection has reliable effect, and the injection is stored in a liquid injection or a powder injection, and is directly injected into tissues, blood vessels or organs of a human body in a liquid state when in clinical application.
