Veltin is made by DPT Laboratories, Ltd., for Stiefel Laboratories, Inc.
As stated previously, Veltin contains two different active ingredients: clindamycin and tretinoin. Tretinoin belongs to a group of medications known as retinoids, meaning it is chemically related to
vitamin A. Tretinoin and other retinoids probably work by suppressing inflammation and slowing rapid skin cell growth.
Clindamycin belongs to a group of antibiotics known as lincosamides. This substance works by inhibiting part of bacterial ribosomes. Ribosomes are parts of cells that make proteins.
By inhibiting the ribosomes, clindamycin interferes with the ability of bacteria to make proteins, which is necessary for the bacteria to grow and multiply. Clindamycin specifically inhibits the 50S subunit of the ribosome. Since human cells do not have a 50S subunit, they are spared from the effects of the antibiotic.
