Question 1

Methods of Drug Administration

Answer 1

Oral Administration
Subcutaneous Injection
Intravenous Injection
Intramuscular Injection
Intraperitoneal
Rectal Administration

Question 2

This is the most common route of drug administration using solid, liquid or semi liquid forms of drugs, In dogs, cats, and poultry; tablets or pills can be placed directly at the base of the tongue while applying pressure ate the side of the mouth to keep it open while administering the drug. While liquids can easily be administered applicator (syringe). In laboratory animals this can be facilitated using an oral feeding needle or a French catheter attached to a syringe. In large animals this can be also facilitated by using a drenching gun (cattle, sheep, goat) stomach tube or a paste preparation (horse).

Answer 2

Oral Administration

Question 3

The drug can be introduced directly underneath the skin by injection. The needle must be inserted to its full length to avoid loss liquid upon withdrawal, The common site employed are the loose skin at the dorsal thoracic or neck area, the abdomen and the fold near the forelimbs and the hind limbs.

Answer 3

Subcutaneous Injection

Question 4

The following are the intravenous injection sites recommended for different animals: dog – cephalic, saphenous and jugular vein; pig – anterior vena cava; rats – tail vein; poultry – wing vein. Always employ a sharp and sterile needle. Inject the drug slowly, if the needle is not in the vein resistance will be felt while injecting and blanching will be observed in the surrounding connective tissue.

Answer 4

Intravenous Injection

Question 5

The drug is Injected at the ham muscle (gluteus) and plunger is always pulled back to make certain that the needle is not in the vein. Neck muscle may also used in large animals (cattle and horse.)

Answer 5

Intramuscular Injection

Question 6

The drug is injected into the peritoneal cavity where absorption is rapid. By holding the animal head downward, and injecting into the lower half of the abdomen, intraintestinal or other intravisceral injections maybe avoided.

Answer 6

Intraperitoneal

Question 7

This can be facilitated by inserting a rubber tubing attached to a syringe or a French catheter rectally at approximately 2 – 3 inches.
