If the lipid envelope of the virus is destroyed, the contents will easily be destroyed and ingested by the secretions of the body like the HCl acid of the stomach and other digestive enzymes in the saliva, etc.
This may be a point of power for the virus, because in the mouth there is nothing that can stop or digest the lipid, the lipid will not start to be digested until it passes the stomach to reach the duodenum where the lipid will start to be digested.
Now most of medical drugs fall into two main groups: acidic and alkaline...
Ponstan is the Mefenamic acid
Aspirin is the Acetyl Salicylic acid
Paracetamol or Panadol is the Acetaminophen which is also acidic.
And there are many acidic drugs which work against microbes like Fucidin or Fucidic acid ..etc.
Alkaline or alkaloid drugs such as:
My idea here which could be correct or wrong, but worth of consideration :
To alkalanize the patient by giving the sodium bicarbonate orally or if the patient is not in good situation by parentral route as you treat the patient with acidosis.
Therefore, when the blood is alkaline it may help destroying the lipid wall of the virus and then getting rid of it or helping the body to get rid of the virus.
Moreover, if the patient is OK, he can take the sodium bicarbonate orally (which is the substance used in bakery and in cold drinks like the Pepsicola and other similar cold drinks.)
So to rinse and gargle the mouth and pharynx with sodium bicarbonate solution may be helpful in preventing the virus, and all success is granted by God Most Gracious.
God is the All-Knowing.
