Argyrol is the trade name for an antiseptic for mucous membranes which consists of compounded solutions of mild silver protein. Argyrol is synonymous with the chemical Mild Silver Protein (MSP) which is pharmaceutical grade for use in medicine and sterile processes. MSP is a molecule produced in the chemical industry in Europe, consisting of elemental silver conjugated along the helix of a denatured protein molecule derived from caseinate of strictly regulated certified livestock. Argyrol 10% is 20,000 ppm with particle sizing molecular range from <8 nm to average <14.3 nm. Argyrol is a local anti-infective most familiar for both ophthalmic and upper respiratory disinfection. Widely publicized for its value to resolve gonorrhea infections, it was known to prevent gonorrheal blindness and other pathogenic bacterial and viral infections to the eyes of newborn infants. [1] Albert C. Barnes developed and commercialized Argyrol as treatment and prevention technology.[ citation needed ]
Argyrol was first made commercially available in 1901 by the Barnes and Hille Chemists Company. The name has remained a registered trademark since Barnes' USPTO registration was first issued in 1902. [2] In 1903, Medical News reported that Barnes had read a paper at the Tri-State Medical Society, in which he said Argyrol could be used to treat conjunctivitis, ophthalmia neonatorum, gonorrheal ophthalmia, otitis media, genitourinary infections and inflammations and urethritis. [3] In April 1907, Barnes bought out Hille and organized the A.C. Barnes Company to continue the manufacture and global sales of Argyrol from three headquarters located in the United States, Great Britain, and Australia. Argyrol was never patented because Barnes instead strategized to define the mark as its molecule for antiseptic use and promote it exclusively through protection of his Argyrol trademark. [4]
Argyrol disinfection of mucous membranes benefit became public health policy to the eyes of newborns, required on birth certificates. The Surgeon General of the United States mandated Argyrol disinfection against the Spanish Influenza pandemic of 1918, as noted in the DTRA December 2006 report regarding US troops stationed at the Presidio in San Francisco all remaining uninfected by the use of Argyrol. Newspapers during the pandemic informed the public of physician recommendation for the use of Argyrol to the nose and throat and 'spray stations' were established on the street in New York. Nebulization of Argyrol was implemented but it is extraordinary that very little mention of Argyrol is found in contemporary articles about the pandemic. Argyrol disinfection was instrumental as to how the 1918 pandemic was brought under control, in addition to the same safety measures implemented to reduce the infection rates of the pandemic in 2020. Argyrol disinfection also was mandated during quarantine against other diseases such as diphtheria and a variety of uses of Argyrol was the WWII advantage of US and Allied forces. Argyrol was World Health Organization Essentials Medicine listed since inception and into the first decade of the 21st century. Argyrol was in almost every First Aid Safety kit for the workplace, school nurses' offices and public health clinics until manufacture was interrupted as observed by Dr. Leila Denmark, co-creator of the pertussis (Whooping Cough) vaccine and a staunch advocate for the use of Argyrol in her book "Every Child Deserves A Chance", noted interruption of Argyrol's availability during the 1970s.[ citation needed ]
For World War II, Argyrol post-exposure male sexual hygiene was mandated by the U.S. and Allied armed forces for sexually transmitted venereal disease prevention. With the advent of antibiotics, prevention was replaced by the promise of cures by injection. Argyrol Anti-Infective was prescribed less often because Argyrol's 10% Stabilized Solution was available without a prescription. Pharmacies also compounded solutions of mild silver protein at varied strength and by prescription. Argyrol was an important treatment for ophthalmic infections and at least until 1943, was preferred over silver nitrate as well. [5] Found effective and reliable for treatment of a range of conditions in human and veterinary medicine, the sales of the drug brought in steady profits for decades. Barnes used the money made when he owned Argyrol to accumulate a large art collection of mainly French Impressionist works which today form the core holding of the Barnes Foundation, an educational art institution established by his will. The paintings were valued in March 2010 at $25 billion. [6] [7]
Argyrol was manufactured by A.C. Barnes Company until the Zonite Products Corporation acquired the firm in 1929. [5] Argyrol products also were dispensed in independent pharmacy-labelled bottles. A succession of only five entities acquired the Argyrol trademark registration over the decades, keeping alive the right to use the mark Argyrol as reflected in the public record of the USPTO, the foundation of WIPO. The Argyrol trademark was guarded to ensure the quality and protect the reputation of the drug by Barnes, which resulted in a particular protection under law issuing to Argyrol by legal decision in jurisprudence. Zonite Products Corporation rightfully cautioned their Argyrol buyers to beware of purchasing imitations of Argyrol which contained other competitive silver compounds that resembled Argyrol. [8]
The silver protein molecule has been in clinical use for over 120 years with ample clinical data supporting its benefit and versatility. FOIA request of FDA noted no Argyrol adverse events reported during all that time. Although Argyrol is used as a synonym for the chemical descriptions silver vitelline and mild silver protein, Barnes insisted Argyrol was different. A silver-gelatin colloid, made by the reaction of silver nitrate, sodium hydroxide and gelatin, in which a complex colloidal aggregate is formed, Barnes could rightfully assert Argyrol differed in its chemical assay, for instance, as it was claimed to contain over 30% silver. When compounded in varying strengths, nevertheless Argyrol is silver protein identified as to its molecule stated in its mark description and Barnes was forced to accept the designation. Argyrol is an over-the-counter internationally recognized anti-infective drug that is drug regulatory compliant, immediate to manufacture and market distribution in all jurisdictions. Drug regulatory administrative adjudication by the US Food and Drug Administration to mandate New Drug Applications for all silver drugs in the class [Final Rule in 1999] resulted to effectively give Argyrol a monopoly, as Argyrol is the only OTC silver drug continuously in commerce in medicine since the 1901 date of launch by Barnes and Hille. [9] Argyrol, called the most useful medicine of all time,[ citation needed ] is not found utilized in contemporary public health because NIH/NIAID/DAIDS opinion holds that "people won't do it", as stated by then DAIDS Director in answer to October 2019 direct query.[ original research? ][ citation needed ]
Chloramphenicol is an antibiotic useful for the treatment of a number of bacterial infections. This includes use as an eye ointment to treat conjunctivitis. By mouth or by injection into a vein, it is used to treat meningitis, plague, cholera, and typhoid fever. Its use by mouth or by injection is only recommended when safer antibiotics cannot be used. Monitoring both blood levels of the medication and blood cell levels every two days is recommended during treatment.
Penicillins are a group of β-lactam antibiotics originally obtained from Penicillium moulds, principally P. chrysogenum and P. rubens. Most penicillins in clinical use are synthesised by P. chrysogenum using deep tank fermentation and then purified. A number of natural penicillins have been discovered, but only two purified compounds are in clinical use: penicillin G and penicillin V. Penicillins were among the first medications to be effective against many bacterial infections caused by staphylococci and streptococci. They are still widely used today for different bacterial infections, though many types of bacteria have developed resistance following extensive use.
Antiviral drugs are a class of medication used for treating viral infections. Most antivirals target specific viruses, while a broad-spectrum antiviral is effective against a wide range of viruses. Antiviral drugs are a class of antimicrobials, a larger group which also includes antibiotic, antifungal and antiparasitic drugs, or antiviral drugs based on monoclonal antibodies. Most antivirals are considered relatively harmless to the host, and therefore can be used to treat infections. They should be distinguished from virucides, which are not medication but deactivate or destroy virus particles, either inside or outside the body. Natural virucides are produced by some plants such as eucalyptus and Australian tea trees.
The medical uses of silver include its use in wound dressings, creams, and as an antibiotic coating on medical devices. Wound dressings containing silver sulfadiazine or silver nanomaterials may be used to treat external infections. The limited evidence available shows that silver coatings on endotracheal breathing tubes may reduce the incidence of ventilator-associated pneumonia. There is tentative evidence that using silver-alloy indwelling catheters for short-term catheterizing will reduce the risk of catheter-acquired urinary tract infections.
Silver nitrate is an inorganic compound with chemical formula AgNO
3. It is a versatile precursor to many other silver compounds, such as those used in photography. It is far less sensitive to light than the halides. It was once called lunar caustic because silver was called luna by ancient alchemists who associated silver with the moon. In solid silver nitrate, the silver ions are three-coordinated in a trigonal planar arrangement.
In molecular biology and pharmacology, a small molecule or micromolecule is a low molecular weight organic compound that may regulate a biological process, with a size on the order of 1 nm. Many drugs are small molecules; the terms are equivalent in the literature. Larger structures such as nucleic acids and proteins, and many polysaccharides are not small molecules, although their constituent monomers are often considered small molecules. Small molecules may be used as research tools to probe biological function as well as leads in the development of new therapeutic agents. Some can inhibit a specific function of a protein or disrupt protein–protein interactions.
A disinfectant is a chemical substance or compound used to inactivate or destroy microorganisms on inert surfaces. Disinfection does not necessarily kill all microorganisms, especially resistant bacterial spores; it is less effective than sterilization, which is an extreme physical or chemical process that kills all types of life. Disinfectants are generally distinguished from other antimicrobial agents such as antibiotics, which destroy microorganisms within the body, and antiseptics, which destroy microorganisms on living tissue. Disinfectants are also different from biocides—the latter are intended to destroy all forms of life, not just microorganisms. Disinfectants work by destroying the cell wall of microbes or interfering with their metabolism. It is also a form of decontamination, and can be defined as the process whereby physical or chemical methods are used to reduce the amount of pathogenic microorganisms on a surface.
In the fields of medicine, biotechnology and pharmacology, drug discovery is the process by which new candidate medications are discovered.
Medicinal or pharmaceutical chemistry is a scientific discipline at the intersection of chemistry and pharmacy involved with designing and developing pharmaceutical drugs. Medicinal chemistry involves the identification, synthesis and development of new chemical entities suitable for therapeutic use. It also includes the study of existing drugs, their biological properties, and their quantitative structure-activity relationships (QSAR).
An antimicrobial is an agent that kills microorganisms (microbicide) or stops their growth. Antimicrobial medicines can be grouped according to the microorganisms they act primarily against. For example, antibiotics are used against bacteria, and antifungals are used against fungi. They can also be classified according to their function. The use of antimicrobial medicines to treat infection is known as antimicrobial chemotherapy, while the use of antimicrobial medicines to prevent infection is known as antimicrobial prophylaxis.
Povidone-iodine (PVP-I), also known as iodopovidone, is an antiseptic used for skin disinfection before and after surgery. It may be used both to disinfect the hands of healthcare providers and the skin of the person they are caring for. It may also be used for minor wounds. It may be applied to the skin as a liquid, an ointment or a powder.
Prontosil is an antibacterial drug of the sulfonamide group. It has a relatively broad effect against gram-positive cocci but not against enterobacteria. One of the earliest antimicrobial drugs, it was widely used in the mid-20th century but is little used today because better options now exist. The discovery and development of this first sulfonamide drug opened a new era in medicine, because it greatly widened the success of antimicrobial chemotherapy in an era when many physicians doubted its still largely untapped potential. At the time, disinfectant cleaners and topical antiseptic wound care were widely used but there were very few antimicrobial drugs to use safely inside living bodies. Antibiotic drugs derived from microbes, which we rely on heavily today, did not yet exist. Prontosil was discovered in 1932 by a research team at the Bayer Laboratories of the IG Farben conglomerate in Germany led by Gerhard Domagk. Domagk received the 1939 Nobel Prize in Physiology or Medicine for that discovery.
Neonatal conjunctivitis is a form of conjunctivitis which affects newborn babies following birth. It is typically due to neonatal bacterial infection, although it can also be non-infectious. Infectious neonatal conjunctivitis is typically contracted during vaginal delivery from exposure to bacteria from the birth canal, most commonly Neisseria gonorrhoeae or Chlamydia trachomatis.
Albert Coombs Barnes was an American chemist, businessman, art collector, writer, and educator, and the founder of the Barnes Foundation in Philadelphia, Pennsylvania.
Bleach is the generic name for any chemical product that is used industrially or domestically to remove colour (whitening) from fabric or fiber or to disinfect after cleaning. It often refers specifically to a dilute solution of sodium hypochlorite, also called "liquid bleach".
Aspirin, an organic compound that does not occur in nature, was first synthesised in 1899.
Debiopharm is a privately-held Swiss biopharmaceutical company mainly active in development and clinical testing of drug candidates. It was founded in 1979 by Rolland-Yves Mauvernay.
Water chlorination is the process of adding chlorine or chlorine compounds such as sodium hypochlorite to water. This method is used to kill bacteria, viruses and other microbes in water. In particular, chlorination is used to prevent the spread of waterborne diseases such as cholera, dysentery, and typhoid.
Mark L. Nelson is an American chemist specializing in the field of antibiotics and tetracyclines. His synthesis techniques have resulted in over 40 patents and he conceived and synthesized with Mohamed Ismail along with Laura Honeyman, the tetracycline antibiotic Omadacycline (Nuzyra), the first of the Aminomethylcycline subclass of tetracyclines to reach medical use. Nuzyra is useful against resistant bacteria and used for severe cases of skin infections, ABSSSIs, Community Acquired Pneumonia (CABP) and nontuberculosis mycobacteria. Nuzyra also has demonstrated activity against Anthrax, and was purchased by the US government under a BARDA contract for Project Bio-shield to treat anthrax exposure, and is now in the Strategic National Stockpile in the US in case of a bioterrorism attack. Nuzyra was also approved for use against the Plague, caused by Yersinia pestis infections.
Amy M. Barrios is an American medicinal chemist working as a professor of Medicinal Chemistry and the Associate Dean for Postdoctoral Affairs for the University of Utah. Barrios' research lab focuses on developing probes to study protein tyrosine phosphatase (PTP) activity and regulation.
He and a brilliant young German student, Hermann Hille, worked out the formula for Argyrol, a mild silver protein solution for which doctors had many uses—to treat gonorrhoea, including gonorrheal blindness, relieve severe nasal congestion.... In 1928, with superb timing, Barnes sold out Argyrol for an estimated $4,000,000.
