Nomifensine was developed by Hoechst AG as a potent inhibitor of noradrenaline, dopamine, and 5-HT uptake displayed antidepressant activity. It was first marketed in the UK in 1977 for the treatment of depression. Between 1977 and 1982 there were reports of hemolytic anemia in association with the drug, and this suspected adverse reaction was included in the 1981 edition of the data Sheet Compendium. FDA published a notice of its determination that Merital capsules were removed from the market for safety reasons.

Geocillin, a trade name is the sodium salt of the indanyl ester of carbenicillin disodium, which used to treat acute and chronic infections of the upper and lower urinary tract and in asymptomatic bacteriuria due to susceptible strains of bacteria. In addition, Geocillin was also indicated in the treatment of prostatitis due to susceptible strains of the following organisms: Escherichia coli; Enterococcus (S. faecalis); Proteus mirabilis; Enterobacter sp. Free carbenicillin is the predominant pharmacologically active fraction of Geocillin. After absorption, Geocillin is rapidly converted to carbenicillin by hydrolysis of the ester linkage. Carbenicillin exerts its antibacterial activity by interference with final cell wall synthesis of susceptible bacteria. Penicillins acylate the penicillin-sensitive transpeptidase C-terminal domain by opening the lactam ring. This inactivation of the enzyme prevents the formation of a cross-link of two linear peptidoglycan strands, inhibiting the third and last stage of bacterial cell wall synthesis. In 2008 Pfizer has decided to discontinue the manufacturing of Geocillin (carbenicillin indanyl sodium)

Bisdisulizole disodium (also known as disodium phenyl dibenzimidazole tetrasulfonate) under the brand name Neoheliopan AP is marketed in some Europe countries and in Australia. This compound is a part of sunscreens to absorb UVA rays.

Ensulizole (INN) (phenylbenzimidazole sulfonic acid) is a common sunscreen agent. In 1999, the United States Food and Drug Administration regulated that the name ensulizole be used on sunscreen labels in the United States. It is a selective UVB filter, allowing almost all UVA transmission. The scope of UVB is 290 to 340 nanometers whereas the UVA range is 320 to 400 nanometers. For better UVA protection, it must be paired with avobenzone, titanium dioxide, or zinc oxide; outside of the United States it can also be paired with a UV absorber of the Tinosorb or Mexoryl types. Because is water-soluble, it has the characteristic of feeling lighter on skin. As such, it is often used in sunscreen lotions or moisturizers whose aesthetic goal is a non-greasy finish. The free acid is poorly soluble in water, so it is only used as its soluble salts
