47Įxcessive concentrations of the active compound at the injection site (initial peak concentrations) are avoided by masking the irritating agent through complexation. Other factors include precipitation of the drug at the injection site, and localized cell lysis. 47 Among the factors responsible for painful injections, the most important are the drug's solubility in aqueous medium, the viscosity, the pH and the hypo- or hyperosmotic character of the injected drug solution, the amount of the injected volume, the site of injection, the pain tolerance of the patient, and the technique of administration. Injection pains are usually accompanied by haemorrhage, oedema, inflammation and tissue necrosis. When an initially painful intravenous or intramuscular injection must be administered repetitively, patient reluctance develops. Wermuth, in The Practice of Medicinal Chemistry (Second Edition), 2003 B Avoidance of painful injections Parecoxib: In a double-blind, randomized, placebo-controlled study with venous occlusion in 150 patients, the incidence of any pain was significantly less with parecoxib 40 mg (26%) than with parecoxib 20 mg (44%) and saline (58%). However, in another study in 101 patients, ketorolac 10 mg given before propofol had no effect. In a double-blind, randomized, placebo-controlled study in 90 patients pre-treatment with ketorolac + lidocaine was more effective than no pretreatment. A lower dose of ketorolac 10 mg with venous occlusion for 120 seconds achieved the same effect. Ketorolac: In a double-blind, randomized study in 180 patients pretreatment with intravenous ketorolac 15 mg and 30 mg reduced propofol-induced pain. They said this technology could be used for many types of vaccines against infectious diseases.In Meyler's Side Effects of Drugs (Sixteenth Edition), 2016 Non-steroidal anti-inflammatory drugs (NSAIDs)įlurbiprofen: In 250 patients intravenous flurbiprofen 50 mg immediately before propofol injection completely abolished injection pain and was more effective than lidocaine when flurbiprofen was given 1 minute before propofol injection it was less effective.

Researchers are testing the COVID-19 vaccine. MORE NEWS: Police: Boy, 8, Survives Fall From 7th Floor Window In North Miami Or more specifically, how you could give yourself your shots. DeSimone said the results are promising, and within five years, this could be how you get your shots.
PAINFUL SHOTS PATCH
Right now, the patch is being tested on animals. “When you think about global access, you’re gonna need things like that,” Dr. It also wouldn’t need to be kept as cold as vaccines that are used in liquid form. That means each person would require a smaller amount of vaccine.
PAINFUL SHOTS SKIN
“We have 100 to 1,000 times more of the targeted immune cells in the dermis of our skin than we do in our muscle,” he said. READ MORE: Police Investigate Burglary Of Business In Miami DeSimone says not only is the patch painless, it’s also more effective than traditional shots.

The microneedles on the patch are so small they can hardly be felt. “And so, our approach was to directly 3D-print the microneedles and use a breakthrough in 3-D printing that we pioneered,” he said. Joseph DeSimone at Stanford University is working with researchers at UNC on a tiny patch that can deliver vaccines when applied to the skin. Aileen Marty Finds Rise In COVID Cases Alarmingĭr. READ MORE: FIU’s Infectious Disease Specialist Dr. MIAMI (CBSMiami) – Researchers at the University of North Carolina at Chapel Hill are developing a new technology that could make getting the COVID-19 vaccine, flu shots, and childhood vaccines pain-free and without needles.Īccording to the CDC, as many as 25 percent of adults and many children have a fear of needles, some so severe it prevents them from getting vaccinated.
