Nitrosamines can be formed through various chemical processes, including the reaction between nitrites and secondary amines in certain conditions. It is a N-Nitroso of secondary amine present in Drotaverine. Nitrosamines are part of a broader class of compounds known as N-nitroso compounds. Drotaverine is an antispasmodic medication used to alleviate smooth muscle spasms, particularly in the gastrointestinal and genitourinary tracts. Structurally, it is a quaternary ammonium derivative. Drotaverine works by inhibiting phosphodiesterase enzymes, leading to an increase in cyclic AMP levels, which subsequently results in smooth muscle relaxation. Administered orally, it is commonly prescribed to relieve conditions such as irritable bowel syndrome and uterine spasms. Buy high quality N-Nitroso Drotaverine from Molsyns Research.
