Ivermectin Description 2022
STROMECTOL (Ivermectin) is a semisynthetic, anthelmintic agent for oral administration. Ivermectin is derived from the avermectins, a class of highly active broad-spectrum, antiparasitic agents isolated from the fermentation products of Streptomyces avermitilis.
Ivermectin is a mixture containing at least 90% 5-Odemethyl-22,23-dihydroavermectin A1a and less than 10% 5-O-demethyl-25-de(1-methylpropyl)-22,23-dihydro25-(1-methylethyl)avermectin A1a, generally referred to as 22,23-dihydroavermectin B1a and B1b, or H2B1a and H2B1b, respectively
The U.S. FDA approves ivermectin tablets to treat people with intestinal strongyloidiasis and onchocerciasis, two conditions caused by parasitic worms. In addition, Ivermectin is indicated to treat onchocerciasis due to the nematode parasite Onchocerca volvulus. Ivermectin is also used in veterinary applications to prevent or treat internal and external parasitic infections in animals. When used in appropriate doses for approved indications, Ivermectin is generally well tolerated.
In addition, some topical forms of Ivermectin are approved to treat external parasites like head lice and skin conditions such as rosacea. Zydus Lifesciences Limited (formerly Cadila Healthcare Limited) received final approval from the USFDA to market Ivermectin Cream, 1%, Soolantra. Ivermectin Cream is used for the treatment of inflammatory lesions of rosacea. Soolantra will be manufactured at the group’s topical manufacturing facility in Ahmedabad, India.
As of August 2022, the U.S. FDA and the WHO recommend not to use Ivermectin for SARS-CoV-2 virus infections or COVID-19 treatments except in the context of a clinical trial. However, if your health care provider writes you an ivermectin prescription, fill it through a legitimate source such as a pharmacy, and take it exactly as prescribed, says the FDA.
The U.S. Centers for Disease Control and Prevention (CDC) issued Health Alert Network Health Advisory CDCHAN-00463 on April 25, 2022, updating healthcare providers, public health departments, and the public about the availability and use of recommended therapies for COVID-19.
The U.S. CDC says Ivermectin is indicated to treat the following infections: Strongyloidiasis of the intestinal tract. Ivermectin is indicated for treating intestinal (i.e., nondisseminated) strongyloidiasis due to the nematode parasite Strongyloides stercoralis. This indication is based on clinical studies of comparative and open-label designs, in which 64-100% of infected patients were cured following a single 200-mcg/kg dose of Ivermectin.
Ivermectin is contraindicated for those five years of age or those weighing less than 15 kilograms and individuals with liver or kidney disease.
Ivermectin Use Against COVID-19
Ivermectin is not authorized or approved by the U.S. FDA to prevent or treat COVID-19. In addition, the U.S. National Institutes of Health's COVID-19 Treatment Guidelines Panel determined on February 11, 2021, that there are currently insufficient data to recommend Ivermectin for the treatment of COVID-19. On October 19, 2021, the Canadian government issued a notice saying, 'Ivermectin is not authorized to prevent or treat COVID-19 and may cause serious health problems.' Additionally, the WHO recommendation concerning Ivermectin was published on 31 March 2021 as the fourth version of the WHO living guideline and in the BMJ as Rapid Recommendations.
Ivermectin Use Against Human Adenoviruses
Human adenoviruses (HAdVs) represent a ubiquitous and clinically important pathogen without an effective antiviral treatment. HAdV infections typically cause mild symptoms; however, individuals such as children, those with underlying conditions, and those with compromised immune systems can develop severe disseminated disease. Our study results demonstrate that Ivermectin, an FDA-approved antiparasitic agent, is effective at inhibiting the replication of several HAdV types in vitro.
Ivermectin Overdose Adverse Effects
The U.S. CDC reported on August 26, 2021, that ivermectin side effect calls have increased sharply, to a five-fold increase from baseline. These reports are also associated with increased frequency of adverse effects and emergency department/hospital visits; gastrointestinal symptoms such as nausea, vomiting, and diarrhea; Low blood pressure (hypotension); Neurologic effects such as decreased consciousness, confusion, hallucinations, central nervous system depression, seizures, coma, and death.
Ivermectin Revenues 2021
The JAMA Network published a Letter on January 13, 2022 - U.S. Insurer Spending on Ivermectin Prescriptions for COVID-19. Insurer spending, estimated at $2.5 million in the week of August 13, 2021, would extrapolate to $129.7 million annually. The true amount of waste is even higher because estimates did not include Medicaid spending.
Ivermectin News 2021 - 2022
