An Essay on Patent Medicines Containing Sulfa
The first antibiotics ever discovered were sulfa drugs which contained chemicals known as sulfonamides and worked at the molecular level. They were first used during the 1930s triggering an astounding revolution in medicine (NIH, 2012). These drugs virtually treated a range of bacterial infections that had the possibility of being fatal such as streptococcal infections (notably scarlet fever, erysipelas, and puerperal sepsis), pneumonia, and meningitis. During the mid-1930s (especially 1936) Pneumonia was incredibly fatal accounting for approximately 8% of total deaths (Jayachandran, 2008). Following their discovery, there was a huge spike in the production and sales of the drugs with over 10 to 15 million people being treated with them in 1940 alone (Hecht, 1984). The drug gained a cult following among people and was called “the miracle of miracles” it saved millions of lives from Winston Churchill to Franklin Delano Roosevelt’s son (Hager, 2006)
As most bacteria do over time, a resistance to sulfa drugs was developed replacing them with penicillin. However, sulfa drugs are still utilized to treat a variety of bacterial infections. They work by binding and inhibiting a specific enzyme called dihydropteroate synthase (DHPS) which is crucial for the synthesis of the essential nutrient folate (NIH, 2012). Despite its miracles, sulfa patented medicines also had their downfalls.
Dr. James Stephenson, a country doctor in Oklahoma, noticed an alarming rate of fatalities around his region in 1937. The suspected culprits for the fatalities ranged from kidney failure to poison.Upon reading an article in the Journal of the American Medical Association that highlighted ...

Aspirin has grown so much in popularity that about 35,000 metric tons of it is produced and consumed each year to meet the consumer’s demand. 35,000 metric tons is equivalent to 100 billion standard aspirin tablets (10). That many tablets means that the market for aspirin is very good. Today, Aspirin is known as the leading non-prescription medicine of all time. It is the most common pill taken for pain, inflammation and fever. It has grown all over the world, being made available in eighty countries (9). It would not be surprising if one day, all the countries would have aspirin available to them.
Years later other scientists were also intrigued by the possibilities of penicillin and produced enough penicillin to prove that it was a useable antibiotic. The scientists from Great Britain were developing all of this during World War II, and unfortunately funding for their drug was unavailable due to the war. They decided to bring their concepts to the United States, and once enough was made, it was eventually used, to treat wounded soldiers during World War I.

“Dr. Janet Woodcock, director of the F.D.A. 's Center for Drug Evaluation and Research said people are being harmed and some of the harm is preventable ' ' (Le Fanu, 2014). With millions of drugs on the market, and with multiple drugs just for one ailment, it wouldn’t take much to cause a wrong combination that could cause injury or death. Hospitals across the U.S. reported in 2011 adverse reactions from prescription drugs caused 2.2 million injuries and 106,000 deaths that two-thirds could have been prevented with proper monitoring of prescription drugs.

In 1928, Alexander Fleming, a Scottish biologist, pharmacologist, and botanist, discovered the first natural antibiotic: Penicillin. All of you reading this have at some point in time made use of his discovery. Penicillin antibiotics were among the first drugs to be effective against many previously serious diseases, such as syphilis and infections caused by staphylococci and streptococci. Antibiotics in general remain one of the cornerstones of modern health care, acting as something we all hope to rely on when we get sick. We could very easily name the 20th century “the age of the antibiotic,” and it would be well deserved, indeed. But time is running out.
Throughout history disease has run rampant taking many lives with every passing day. Finding a cure or even just a tool in the battle has been the main focus of scientist throughout time. This focus is what brought us the discovery of antibiotics. Over the years antibiotics have been misused by patients, over prescribed by physicians and have led to resistant strains of bacteria.
Penicillin has been considered a miracle drug by doctors ever since it was first used in 1942. It could cure nearly every disease that it was prescribed for and was the cause of a major turning point in World War 2. Yet, for the past forty years there have been bacteria strains discovered that can withstand the power of Penicillin. The mass production and misuse of penicillin has caused the miracle drug to become ineffective towards serious infections.
In the last decade, the number of prescriptions for antibiotics has increases. Even though, antibiotics are helpful, an excess amount of antibiotics can be dangerous. Quite often antibiotics are wrongly prescribed to cure viruses when they are meant to target bacteria. Antibiotics are a type of medicine that is prone to kill microorganisms, or bacteria. By examining the PBS documentary Hunting the Nightmare Bacteria and the article “U.S. government taps GlaxoSmithKline for New Antibiotics” by Ben Hirschler as well as a few other articles can help depict the problem that is of doctors prescribing antibiotics wrongly or excessively, which can led to becoming harmful to the body.
Alexander Fleming started the history of antibiotics in the 1920's with his discovery of penicillin.When penicillin was first discovered and used widely, it was touted as a wonder drug, and consequently was used as one.Though not necessarily harmful to the patient penicillin was used for much more infections than it was able to combat.Today the same practice is observed in the medical profession, however at this point it is due more to the detriment of an uneducated public.Studies have been carried out that show the huge over usage of antibiotics.In the seventies Soyka et al, concluded, "60% of physicians surveyed gave antibiotics for the treatment of the common cold."[3], and by common knowledge the common cold is a virus, something that cannot be treated by an antibiotic.Nyquist
Antibiotics have been critical in fighting bacteria-caused diseases for the past 60 years. Bacteria in the human body are able to reproduce at a rapid rate and this is a huge problem when the bacteria are disease-causing. Antibiotics are drugs that are able to stop bacterial growth, and kill off bacteria in living organisms.

Forensic toxicologists have faced numerous challenges throughout the 1800’s and are still facing some of these challenges today. In Gettler’s and Norris’s time of being head of forensics in New York, they faced problems within toxicology study, and some out of toxicology. One of their main problems was metabolizing a poison and determining the lethal dose.
