The prefilled syringe

The prefilled syringe is a qualified newcomer to the syringe market. Up until the 1980s, this medication delivery method, which includes the factory filling of syringes with different medicines, was not that common. Since the 1980s, though, demand has improved for convenient device, which eliminates the need to draw up medicine into a syringe, and thus improves speed at which certain medications can be given. It can also increase accuracy in dosing, since medicine in the prefilled syringe is expected to be the same with each dose. There are now a lot of vaccines that are presented in prefilled forms and some medicines for home use also are obtainable, which many feel helps takes some of the guesswork out of home injections for people who must self-inject medications. The average prefilled syringe contains medicine in a plastic cartridge and has a plastic cap to cover the needle and prevent accidental needle sticks. It’s important to follow specific protocol on injections, but it can be said that the majority of these syringes are single use. This means they’re immediately discarded after injecting the medication. It bears repeating that these syringes are usually not approved for reuse of any kind. As with any needle disposal methods, medical personnel and medical laypeople must discard the syringe in an approved manner. People who self-inject may need to bring syringes back to a doctor or pharmacist for safe disposal; syringes should never go into the trash.

Intravenous Infusion

Intravenous Infusion IV infusion is a direct method by which the drug is administered systematically in to the body.It is given either as a bolus or infused slowly drip by drip.Compared with other routes of administration, the intravenous route is the fastest way to deliver fluids and medications throughout the body. Some medications, as well as blood transfusions and lethal injections, can only be given intravenously. Advantage Precise control of plasma drug concentration The rate can be controlled For large volume of parenteral dose, it is wise to use infusion to remain the blood volume , pH, buffer system unchanged Some drugs can’t given in large volume (like heparine) because that may cause heart collapse in that case Infusion is ideal Some drugs can’t take orally so infusion is used With a narrow therapeutic window contained drugs given as infusion Less toxicity Bioavailability is high Dose accuracy Disadvantage Infection may arise at the infusion site Supervisor needed
