REGN-COV2 – Artificial "antibody cocktail" 

Recently a new drug was approved for use in COVID patients in India. Known as REGN-COV2, this new therapy is based on monoclonal antibodies targeting the SARS-CoV-2 virus responsible for COVID. So how does it work? And is there any evidence behind the treatment?

Monoclonal antibodies are made from components of the human immune system. When the human body recognizes a bacteria or virus in the body, the immune system recognizes and processes proteins on the surface of that bacteria or virus. This is presented to the adaptive immune system, and antibodies have produced that lock onto these surface proteins, neutralizing their function and also tagging them for destruction by other white blood cells.

If we identify antibodies capable of efficiently tagging and neutralizing a certain virus, we can identify the cell capable of producing that antibody, clone it and produce it in vast quantities. The antibodies produced from this cloned cell line will be able to target the virus at the same efficiency and have the same ability to neutralize the virus. Just like with vaccines, there is a risk of mutations developing, resulting in changes in the surface protein that reduce binding and neutralizing effects of the antibodies, allowing them to escape and continue to cause disease

REGN-COV2 uses two neutralizing antibodies (Casirivimab/imdevimab), in an effort to minimize the ability of a mutant virus to develop resistance against the antibody cocktail, as the virus would need to develop mutations canceling both antibodies out at once. These antibodies neutralize the receptor-binding domain of SARS-CoV-2 spike protein, preventing viral entry through ACE2 receptors.

In a study published in the New England Journal of Medicine (one of the most prestigious journals in the medical field) data from 275 patients showed a drastic reduction in viral load in patients treated with REGN-COV2. This is clinically significant as hospitalized patients with severe symptoms have higher viral counts than non-hospitalized or asymptomatic patients, suggesting the hypoxaemic, shortness of breath symptoms are related to the viral count and resulting exaggerated immune response.

Based off this result the European Medicines Agency approved the use of REGN-COV2 antibody cocktail in patients who do not require supplemental oxygen but are at high risk of progressing to severe COVID-19.

FDA regulations currently recommend it for patients who are COVID positive with risk factors that may result in their hospitalization but do not recommend it for patients who are already hospitalized, requiring O2 therapy because of COVID or need chronic O2 therapy.

Those that fall into the high-risk categories include patients with a high BMI (over 35), diabetes, on immunosuppressive treatment or with an immunosuppressive disease, over 65 years of age or those with chronic diseases such as renal disease, cardiovascular disease, COPD, or other developmental disorders.

Neurobion Forte: Benefits for Nerve Health and Vitamin B Deficiency

Vitamin deficiencies are a common but often overlooked health issue. Among them, vitamin B deficiency is particularly significant because of its direct impact on nerve function, energy metabolism and overall neurological health. Neurobion Forte is a widely used vitamin B-complex supplement designed to address these deficiencies and support nerve health.

Understanding how Neurobion Forte works and when it is beneficial helps individuals make informed decisions about their nutritional and neurological wellbeing.

 

What Is Neurobion Forte?

Neurobion Forte is a combination supplement containing essential B vitamins, primarily:

  • vitamin B1 (thiamine)
     

  • vitamin B6 (pyridoxine)
     

  • vitamin B12 (cobalamin)
     

These vitamins play a vital role in nerve signal transmission, energy production and maintenance of the nervous system.

 

Why Vitamin B Is Essential for Nerve Health

B vitamins are crucial for:

  • nerve impulse transmission
     

  • myelin sheath formation
     

  • energy metabolism in nerve cells
     

Deficiency can impair nerve function, leading to discomfort and neurological symptoms.

 

Common Causes of Vitamin B Deficiency

Vitamin B deficiency may occur due to:

  • inadequate dietary intake
     

  • poor absorption
     

  • chronic illnesses
     

  • long-term medication use
     

  • alcohol misuse
     

Vegetarians and elderly individuals are particularly at risk of vitamin B12 deficiency.

 

Symptoms of Vitamin B Deficiency

Early symptoms may include:

  • fatigue
     

  • weakness
     

  • numbness or tingling in hands and feet
     

  • poor concentration
     

If untreated, deficiency may progress to more serious neurological problems.

 

How Neurobion Forte Supports Nerve Health

Supports Nerve Repair

Vitamin B12 contributes to nerve regeneration and maintenance of nerve fibres.

 

Improves Nerve Signal Transmission

Vitamin B1 supports proper nerve impulse conduction.

 

Reduces Nerve Irritation

Vitamin B6 helps regulate neurotransmitter synthesis, reducing nerve-related discomfort.

 

Supports Energy Metabolism

B vitamins help convert food into energy, supporting overall nerve and muscle function.

 

Role of Neurobion Forte in Nerve Pain

Nerve pain caused by vitamin deficiency may present as:

  • burning sensation
     

  • tingling
     

  • numbness
     

  • shooting pain
     

In such cases, correcting the deficiency through supplementation may help relieve symptoms over time.

 

Conditions Where Neurobion Forte Is Commonly Used

Neurobion Forte may be prescribed or recommended in cases such as:

  • peripheral neuropathy
     

  • diabetic neuropathy (as supportive care)
     

  • nutritional deficiency-related nerve symptoms
     

  • general weakness associated with vitamin B deficiency
     

It is not a painkiller but supports underlying nutritional correction.

 

Importance of Medical Guidance

While vitamin supplements are widely available, inappropriate or excessive use may cause side effects.

Medical guidance ensures:

  • correct diagnosis
     

  • appropriate dosage
     

  • monitoring of response
     

Self-medication should be avoided, especially for long-term use.

 

Diet and Vitamin B Intake

Dietary sources of B vitamins include:

  • whole grains
     

  • legumes
     

  • dairy products
     

  • eggs
     

  • meat and fish
     

Balanced nutrition remains the foundation of vitamin sufficiency.

 

Who May Benefit Most from Neurobion Forte?

Individuals who may benefit include:

  • those with confirmed vitamin B deficiency
     

  • people with nerve-related symptoms
     

  • elderly individuals with poor nutrient absorption
     

  • individuals with restricted diets
     

Supplementation should complement dietary improvement.

 

Possible Side Effects and Precautions

When taken as advised, Neurobion Forte is generally well tolerated.

However:

  • excessive vitamin B6 intake may cause nerve symptoms
     

  • allergic reactions are rare but possible
     

Always follow professional advice.

 

How Long Does It Take to See Benefits?

Improvement depends on:

  • severity of deficiency
     

  • duration of symptoms
     

  • individual health status
     

Some people notice symptom improvement within weeks, while others require longer support.

 

Neurobion Forte and Overall Wellbeing

Correcting vitamin B deficiency supports:

  • nerve health
     

  • energy levels
     

  • cognitive function
     

  • overall vitality
     

Supplementation is most effective when combined with healthy lifestyle habits.

Conclusion

Neurobion Forte plays an important role in managing vitamin B deficiency and supporting nerve health. By supplying essential B vitamins, it helps restore nerve function, reduce deficiency-related symptoms and improve overall neurological wellbeing. While it can be highly beneficial when deficiency is present, its use should always be guided by medical advice to ensure safety and effectiveness. Balanced nutrition, early diagnosis and appropriate supplementation together form the foundation of healthy nerve function.
