ACTIVE MOIETY
The companies say that the new compound is a highly-selective alpha-1A receptor antagonist, administered as an eye-drop which is expected to lower intraocular pressure in glaucoma patients by facilitating the outflow of fluid from the eye. Pharmacological studies in animals have shown that this efficacy is well-maintained over time.
ACTIVE MOIETY
Novartis Ophthalmics last week announced that it had entered a license option agreement with Kissei Pharmaceutical Co. Ltd. for new glaucoma agent KRG-3332, a highly selective alpha 1A receptor. Studies in animals show the agent successfully reduces intraocular pressure and that efficacy is well-maintained over time.
