The history of penicillin follows observations and discoveries of evidence of antibiotic activity of the mould Penicillium that led to the development of penicillins that became the first widely used antibiotics. Following the production of a relatively pure compound in 1942, penicillin was the first naturally-derived antibiotic.
In 1907 Alfred Bertheim synthesized Arsphenamine, the first man-made antibiotic. In 1927 Erik Rotheim patented the first aerosol spray can. In 1933 Robert Pauli Scherer created a method to develop softgels.

They are still widely used today for various bacterial infections, though many types of bacteria have developed resistance following extensive use. Ten percent of the population claims penicillin allergies , but because the frequency of positive skin test results decreases by 10% with each year of avoidance, 90% of these patients can eventually ...
The antibiotic shortage seems to be linked to secondary bacterial infections happening after kids get these viral illnesses, coupled with pandemic-related supply chain shortages, Fisher says.
It is marketed under the brand names Sumycin, Tetracyn, and Panmycin, among others. Actisite is a thread-like fiber formulation used in dental applications.
