Macular degeneration and Avastin: legal issues
Since 2005, the drug Avastin will be used against the problematic vessel growth in wet macular degeneration. To date, this drug is not for the treatment of macular degeneration officially approved. The manufacturer of Avastin, which is also the manufacturer of Lucentis plans, no approval of Avastin for the field of ophthalmology. Due to the lack of approval for the treatment of macular degeneration and official instructions are missing on potential adverse effects of its use in the eye. Nevertheless, it appears the administration of Avastin, a widely used allopathic methods for the treatment of wet macular degeneration to be.
Avastin was originally comes from the Cancer Research and for example, often used against cancer. In a tumor treatment, the drug Avastin is injected directly into a vein in your arm. Due to the propagation through the bloodstream, it often leads to side effects throughout the body. With the injection of Avastin in the area affected by wet macular degeneration eye, the dose used is much lower and is therefore considered to be fewer side effects. The drug Avastin inhibits angiogenesis on the one hand and seals from other vessels, hence the use in wet macular degeneration. It is an antibody with the drug bevacizumab, which vessel-building, called VEGF-Hormone (VEGF: Vascular Endothelial Growth Factor) is blocked, thus preventing the blood supply of tumors.
The goal, therefore, is a low release of VEGF hormone. .
It may have been found to block the Avastin on this mechanism of action and the abnormal growth of blood vessels in wet macular degeneration and seal leaking blood vessels. At best, it seems possible by a wet macular degeneration back into a dry macular degeneration and thereby preventing the normally serious vision loss through the abnormal vessel growth with a wet macular degeneration.
A so-called off-label therapy, so a drug that can also help with other diseases than those for which it was approved, is allowed in Germany, unless another approved method for this area is available. Since the approval of Macugen and Lucentis, therefore, a certain legal problem is the use of Avastin for wet macular degeneration. Ophthalmologists Avastin in wet macular degeneration in the eye splash move therefore in a legal gray area.
