Breakthrough Drug: Ivermectin Shows 'Astounding' Results Against Coronavirus

"Emergency medical physician Dr. Peter H. Hibberd, M.D., of Palm Beach County, Florida, told Newsmax Friday evening in an exclusive interview that he’s optimistic the drug will prove to be an important therapeutic advance"

“There’s a common denominator here,” said Hibberd. “This drug is salvaging people from their death bed.”

"In some cases, doctors reported just one dose of ivermectin markedly improved a patient’s condition. U. S. patients received a single oral dose, and some of them received a booster dose seven days later. The FDA-approved dose for parasitic infections was used."

"On Thursday, a team of U.S. doctors led by Dr. Jean-Jacques Rajter at the Broward Health Medical Center in Fort Lauderdale, Florida, submitted findings to an institutional review board. According to a medical source familiar with the study, some 250 coronavirus patients were involved in the Broward trial. The results were dramatic, with “statistically significant improvement in mortality,” according to the source.

The blood oxygen level of the first patient treated in early April was 70%, and dropped to just 50% within hours. After receiving the invermectin, the patient stabilized within 24 hours and was discharged from the hospital in one week. "
