Throat infection : A white-label medical device


The HMG product from Vitrobio is an innovative throat spray designed for the treatment of viral or bacterial throat infections. It works by creating a protective filmogenic barrier on the mucosal surface, providing hydration, cleansing, and reducing contaminants through osmotic action. The spray specifically targets pro-inflammatory proteins such as cytokines and interleukins, offering rapid and effective relief from symptoms. A randomized, double-blind clinical trial is currently underway, with promising preliminary results.

Treatment of throat infection


Introducing the HMG product from Vitrobio, a groundbreaking solution for the treatment of viral or bacterial throat infections. This innovative product comes in the form of a 30ml throat spray, designed for ease of use and optimal delivery of the active ingredients.


How this medical device works

The HMG spray works by creating a protective barrier on the mucosal surface, acting as a filmogenic liquid bandage. This barrier serves multiple purposes. Firstly, it provides immediate hydration and cleansing of the surface, ensuring a clean and moist environment conducive to healing. Secondly, it reduces contaminants and debris through an osmotic action, effectively drawing out harmful substances that could impede recovery.


Targeted Action

The true innovation of the HMG spray lies in its targeted action against pro-inflammatory proteins such as cytokines and interleukins. These proteins play a crucial role in the inflammatory response associated with throat infections. By specifically targeting these proteins, the HMG spray can directly address the underlying causes of inflammation, leading to more effective and rapid relief from symptoms.


Vitrobio Research and Development

The development of the HMG spray is based on extensive research conducted by Vitrobio, a company renowned for its innovative approach to medical device manufacturing. The product’s unique mechanism of action is the result of years of research into the role of proteins in disease pathogenesis, and the potential of specific natural polymers to target these proteins.



In conclusion, the HMG spray represents a significant advancement in the treatment of throat infections. Its unique mechanism of action, combined with its ease of use and rapid results, make it a promising addition to the therapeutic options available for these common and often debilitating conditions.

Understanding Throat Infections

Throat infections are a common health issue that can affect individuals of all ages. They are typically caused by viruses or bacteria, and are characterized by symptoms such as a sore throat, difficulty swallowing, and swollen glands.


Causes of Throat Infections

The most common cause of a throat infection is a viral infection, such as the common cold or flu. Bacterial throat infections, while less common, can be more severe. The most well-known bacterial infection is strep throat, caused by the Streptococcus bacteria.


Symptoms of Throat Infections

Symptoms of a throat infection can vary depending on the underlying cause, but often include a sore throat, difficulty swallowing, swollen glands in the neck, and sometimes fever. In the case of a bacterial infection, symptoms may also include white patches on the tonsils or a red rash.


Treatment for Throat Infections

Treatment for throat infections depends on the cause. Viral infections typically resolve on their own with rest, hydration, and over-the-counter remedies to manage symptoms. Bacterial infections, on the other hand, require antibiotics to prevent complications.


Prevention of Throat Infections

Prevention strategies include regular hand washing, avoiding close contact with sick individuals, and maintaining a healthy lifestyle to boost the immune system. Vaccinations can also help prevent certain types of throat infections.


Throat infections, while common, can cause significant discomfort and disrupt daily activities. Understanding the causes, symptoms, and treatment options for these infections can help individuals seek timely medical care and prevent the spread of these illnesses.
