Initial studies using aliphatic beta-nitro alcohols for therapeutic corneal cross-linking. Beta blockers cause your heart to beat more slowly and with less force, which lowers blood pressure. In vitro studies on porcine eyes have shown that aliphatic β-Nitro alcohols act as both formaldehyde and nitrite donors under physiologic pH and temperature to induce crosslinking [1-2] and are capable of inducing cross-links in the cornea with negligible effects on light transmission [1]. Safety of UVA-riboflavin cross-linking of the cornea. Peptide hormones, growth factors, related substances and mimetics. 3-Nitrobenzyl alcohol, 98%. The result of this study encourages further evaluation of these compounds as potential pharmacologic topical stiffening agents for corneoscleral disorders. In vitro studies on porcine eyes have shown that aliphatic β-Nitro alcohols act as both formaldehyde and nitrite donors under physiologic pH and temperature to induce crosslinking [1-2] and are capable of inducing cross-links in the cornea with negligible effects on light transmission [1]. 2012 Jul;23(4):280-7. doi: 10.1097/ICU.0b013e328354865e. Alcohol is an irritant to the cells of the GI tract, and can trigger the release of additional stomach acid that can harm the surrounding tissue even more. When combined with the potential for stomach tissue harm from the antibiotic, this combination can lead to side effects that are much more unpleasant, and even painful. What does this medication do?
