Charles Romley Alder Wright several hours and produced a more potent, acetylated form of morphine, now called "diamorphine (or diacetylmorphine)", also known as heroin. After Wright's death, Heinrich Dreser, a chemist at Bayer Laboratories, continued to test heroin. Bayer marketed it as an analgesic and 'sedative for coughs' in 1898. When its addictive potential was recognized, Bayer ceased its production in 1913. In 1892, Wright was the first to report the existence of the stoichiometric intermetallic compound AlSb (aluminium antimonide), which is now recognized as a compound semiconductor with potential use in high-frequency, low-power consumption microelectronics applications, as well as gamma radiation detection.

Analgesic potential hazards of topical anesthetics entering the bloodstream when applied in large doses to the skin without medical supervision. These topical anesthetics contain anesthetic drugs such as lidocaine, tetracaine, benzocaine, and prilocaine in a cream, ointment, or gel. The word "analgesic" derives from Greek "an-" (, "without"), "álgos" (, "pain"), and "-ikos" (, forming adjectives). Such drugs were usually known as anodynes before the 20th century. Some novel and investigational analgesics include subtype-selective voltage-gated sodium channel blockers such as funapide and raxatrigine, as well as multimodal agents such as ralfinamide..
