5ドルの鼻スプレーでCOVID-19感染リスク70%カット – 新たな研究結果
Imagine if a simple over-the-counter nasal spray could significantly reduce your risk of catching COVID 19. Sounds too good to be true, right? But it’s not just wishful thinking. A groundbreaking study suggests this might actually be possible. And this is the part most people miss. It’s not a new experimental drug, but a familiar antihistamine that’s been safely used for decades. Your medicine cabinet might already hold a secret weapon against COVID 19. A recent study published in Jamama Internal Medicine https colon//jamma internal medicine/full article/283835 found that asastine a widely available over-the-counter nasal spray could help healthy adults fend off the virus. This discovery comes at a critical time as a late summer surge in COVID 19 cases, https covid data tracker.co data home is sweeping across the country including major cities like New York. But here’s where it gets controversial. Could a simple nasal spray really be a gamecher in the fight against CO 19? And if so, why aren’t more people talking about it? A zealistine sold as a steepro allergy. https colon rnyostlink.com btn refals or1 19984c1136920001 btn URL https percent/www.amazon.com/astropro amazon.com/astropro 24hour steroidfree congestion packaging percentpv197V percent Astropo 24 C113692001 btn URL equals or 1 19984 C113692001 and Astropo 24-hour steroid-free congestion packaging % ant Astropro 24 has been a go-to for allergy relief since the 1990s, but recent research suggests it might do more than just clear your sinuses. A study from last year, https, pmc.ncbi.nlm.nih.gov/articles PM researchers in Germany took this a step further, testing whether aastine could act as a preexposure prophylaxis. essentially preventing infections before they start. They recruited 450 healthy adults aged 18 to 65, nearly all of whom had received at least one COVID 19 vaccine dose. Participants were split into two groups. One used Azelastine 0.1% spray three times a day while the other received a placebo. Over 56 days, both groups were tested twice weekly for SARS Kovv2, the virus causing COVID 19. The results were striking. Only 2.2% of those using Azelastine tested positive compared to 6.7% in the placebo group. But here’s the kicker. Those using the spray not only got infected less often, but also took longer to get sick, tested positive for fewer days, and experienced milder symptoms. Dr. Bruce Hirs, an infectious disease specialist at Northwell Health, described it as a small but significant result, highlighting the spray’s antiviral properties and its ability to reduce inflammation in the respiratory tract. The spray was also well tolerated with only two participants reporting serious side effects unrelated to the treatment. Hirsh noted, “It’s a benign intervention that we might include during a busy viral season.” Though he cautioned it’s not a replacement for other preventive measures like vaccination. With its strong safety profile, OTC availability and ease of use as elastine could be a practical tool for preventing CO 19 in high-risk situations such as large gatherings or travel. Researchers are now calling for further studies to exploit its potential against other respiratory viruses like RSV and the flu. But here’s the real question. If Azilastine proves effective, will it be accessible to everyone who needs it? The findings come as the US prepares for another challenging respiratory virus season with a new CO 19 variant already driving up cases. Last week, the FDA approved updated COVID 19 vaccines. https colonnyost.com/827 usnews/fda restricts access to co vaccines for healthy adults and kids. But tightened eligibility rules now restrict access to those 65 and older or with underlying conditions. This shift could create barriers for many. reversing previous guidance that recommended yearly vaccines for everyone 6 months and older. The roll out of these vaccines is already complicated. CVS, for example, now requires a prescription in Washington DC and 13 states, including New York due to local restrictions. In Massachusetts, New Mexico, and Nevada, state laws prevent retailies from administering the vaccine without federal advisory panel approval, even with a prescription. The advisory committee’s midepptember meeting will be pivotal, determining who qualifies for free insurance covered vaccines. Walgreens, meanwhile, says it’s prepared to offer the vaccine where possible. According to CBS News, https www.cbs Walgreens limit access co vaccines required state guidelines. But whether you can get one at your local pharmacy depends on where you live and the evershifting regulatory landscape. So what do you think is as elastine the unsung hero in our fight against CO 19 or is it too early to tell? Should it be more widely recommended? Or are there valid concerns about overreiance on a nasal spray? Let’s hear your thoughts in the comments. This conversation is far from
BREAKING: A groundbreaking new study published in JAMA Internal Medicine reveals that azelastine nasal spray, a common over-the-counter antihistamine, can significantly reduce your risk of getting COVID-19.
KEY FINDINGS:
✅ 70% reduction in COVID infections (2.2% vs 6.7% placebo)
✅ Longer time to infection (31 vs 19 days)
✅ Fewer symptomatic cases
✅ Also reduces rhinovirus infections
✅ Well-tolerated with minimal side effects
HOW IT WORKS:
Azelastine has antiviral properties and soothes the upper respiratory tract lining, reducing inflammation and making it harder for viruses to take hold. This antihistamine has been safely used for decades to treat allergies.
STUDY DETAILS:
– 450 healthy adults in Germany
– 56-day double-blind, placebo-controlled trial
– 0.1% azelastine spray, 3 times daily
