Description | Ocriplasmin is a recombinant (derived from Pichia pastoris) truncated form of human plasmin with a molecular weight of 27.2 kDa. It is a 249 amino acid protein that is made up of two peptide chains. Agent for pharmacologic vitreolysis; thrombolytic agent. FDA approved on October 17, 2012. |
Indication/Disease | Ocriplasmin is a proteolytic enzyme indicated for the treatment for symptomatic vitreomacular adhesion. |
Pharmacodynamics | N.A. |
Mechanism of Action | Ocriplasmin has proteolytic activity against protein components of the vitreous body and the vitreoretinal interface (VRI) (e.g. laminin, fibronectin and collagen), thereby dissolving the protein matrix responsible for the vitreomacular adhesion (VMA). |
Toxicity | The most commonly reported reactions (≥ 5%) in patients treated with ocriplasmin were vitreous floaters, conjunctival hemorrhage, eye pain, photopsia, blurred vision, macular hole, reduced visual acuity, visual impairment, and retinal edema. |
Metabolism | Ocriplasmin is quickly inactivated by protease inhibitor α2-antiplasmin or α2-macroglobulin. |
Absorption | Because of the small dose administered (0.125 mg), ocriplasmin is not expected to be in the systemic circulation following injection. Within 30 minutes after injection, levels of ocriplasmin in the vitreous are 12 mcg/mL. 24 hours after injection, levels in the virtreous are 0.5 mcg/mL |
