146 results about "Mycophenolic acid" patented technology

Mycophenolic acid, (MPA) is a non-competitive reversible inhibitor of the inosine monophosphate dehydrogenase (IMPDH), a key rate-limiting enzyme in the de novo purine synthesis pathway and also called mycophenolate, is an immunosuppressant drug used to prevent rejection in organ transplantation. It was initially introduced as the prodrug mycophenolate mofetil (MMF, trade name CellCept) to improve oral bioavailability. More recently, the salt mycophenolate sodium (trade name Myfortic) has also been introduced. Enteric-coated mycophenolate sodium is an alternative MPA formulation. However, the kinetics of EC-MPS differ in that the drug is enteric coated, dissolves at pH levels of ≥ 5,with the goal of delaying the delivery of MPA until it reaches the small intestine...

Ocular solutions

Ocular solutions containing at least one macrolide antibiotic and / or mycophenolic acid provide anti-inflammatory, anti-cell proliferation, anti-cell migration, anti-angiogenesis, antimicrobial and antifungal effects. In one embodiment, the solution is administered intraocularly after cataract surgery before insertion of a replacement intraocular lens, resulting in reduced posterior capsular opacification which may eliminate the need for a subsequent surgery. The solution may be one that is invasively administered, for example, an irrigation or volume replacement solution containing at least one macrolide antibiotic such as tacrolimus, sirolimus, everolimus, cyclosporine, and ascomycin, or mycophenolic acid. The solution may be one that is non-invasively or topically administered in the form of drops, ointments, gels, creams, etc. and may include eye lubricants and contact lens solutions. The solution may contain a supratherapeutic concentration of agent(s) so that a therapeutic concentration of a topically administered solution accumulates in a diseased ocular structure sufficient to treat the disease.
