Parenteral Administration in Medicine and Pharmacy

Enteral administration refers to drug administration via the gastrointestinal tract, while parenteral administration refers to any method of drug administration that does not utilize the gastrointestinal tract, commonly by injection.
Parenteral administration is often chosen when the drug molecule would be rapidly broken down in the gastrointestinal tract or when a highly localized effect is desired.
Intravenous injection delivers the drug directly into the circulatory system for a rapid onset of action, which is important in emergency situations.
Intramuscular injection delays and prolongs the release of the medicine from the injection site into the circulation, allowing for prolonged drug release.
The intravenous route of injection is routinely used to administer medication to unconscious patients who are unable to swallow or when the gastrointestinal tract is not working.
Patients would prefer to receive their medication as an oral tablet or liquid to swallow, or as a cream, ointment, or transdermal patch to apply to the skin rather than receive treatment via injection, which can be painful or stressful.
Manufacturers prefer to prepare medicines such as tablets or liquids due to the less stringent requirements for manufacturing premises for these non-sterile products compared to the costs associated with manufacturing sterile medicines.
Intravenous injections and infusions, intra-arterial and intracardiac injections, intradermal injections, subcutaneous injections, intramuscular injections, intraspinal injections, intra-articular injections, and ophthalmic injections are all routes of parenteral administration.
Pharmacopoeial requirements for parenteral administration include general requirements and category-specific requirements.
Factors affecting absorption from the injection site include excipients, vehicles for injections, preservatives, antioxidants, pH adjustment and buffers, tonicity adjusting agents, and suspending agents.
Ampoules, vials, and infusion bags and bottles are commonly used containers for parenteral administration.
Parenteral administration is employed not only for medicines but also for fluids for hydration and electrolyte replacement, plus all the nutrients, vitamins, and trace elements normally obtained from a healthy diet supplied by parenteral nutrition provided intravenously.
