Parenteral therapy refers to the administration of medication or fluid directly into the body through injection, infusion, or implantation. The reasons for parenteral therapy are as follows:

1. Rapid onset of action: Parenteral medications are administered directly into the bloodstream, bypassing the gastrointestinal tract and liver, which leads to a faster onset of action. This is particularly useful in emergencies, where quick action is required.

2. Unavailability of oral route: Some medications are not available in the oral form, or the oral route may not be effective due to poor absorption or degradation by the digestive system.

3. Nausea and vomiting: Patients who are vomiting or have nausea may not be able to tolerate oral medications. Parenteral therapy ensures that the medication is absorbed and effective.

4. Inability to swallow: Patients with certain medical conditions such as stroke, esophageal cancer, or Parkinson’s disease may have difficulty swallowing and may require parenteral therapy.

5. Higher bioavailability: Some medications have a higher bioavailability via parenteral route than via oral route, which means that more of the medication reaches the target organ or tissue.

6. Long-term therapy: Some medical conditions require long-term therapy, and frequent administration of oral medication may not be feasible or practical. In such cases, parenteral therapy may be preferred.

7. Restricted drug delivery: Some drugs are only effective when delivered via parenteral route, such as chemotherapy drugs, which require precise delivery to the target cancerous cells.

Parenteral therapy is a crucial mode of drug administration, and is used in various medical settings such as hospitals, clinics, and home care. It is important to follow proper administration techniques and sterile procedures to prevent infections and complications.
