    摘要: Substance delivering punctum plug devices and related methods for treating disorders and diseases of the eye. Some embodiments of the device maximize dissolution of the substance in tears and/or other fluid(s) that distribute to the anterior surface of the eye so as to maximize delivery of the substance to or through the cornea or anterior surface of the eye ball while minimizing loss of substance through other routes.

    摘要: A solid drug core insert can be manufactured by injecting a liquid mixture comprising a therapeutic agent and a matrix precursor into a sheath body. The injection can be conducted at subambient temperatures. The mixture is cured to form a solid drug-matrix core. The therapeutic agent can be a liquid at about room temperature that forms a dispersion of droplets in the matrix material. A surface of the solid drug core is exposed, for example by cutting the tube, and the exposed surface of the solid drug core releases therapeutic quantities of the therapeutic agent when implanted into the patient. In some embodiments, the insert body inhibits release of the therapeutic agent, for example with a material substantially impermeable to the therapeutic agent, such that the therapeutic quantities are released through the exposed surface, thereby avoiding release of the therapeutic agent to non-target tissues.

    摘要: The lacrimal implant delivery systems and methods described herein provide for controlled release of a therapeutic agent for the treatment of disease, including the treatment of glaucoma, ocular hypertension, or elevated intraocular pressure with latanoprost or other anti-glaucoma agents. Treatment of disease, including glaucoma, ocular hypertension, or elevated intraocular pressure with latanoprost or other anti-glaucoma agent in conjunction with penetration enhancer, such as benzalkonium chloride, and/or artificial tears is also provided. Also provided are implants containing a drug core emplacable in a punctum adjacent to an eye of a patient for controlled release of a therapeutic agent such as latanoprost for the treatment of glaucoma, the drug core containing a polymer such as cross-linked silicone, a therapeutic agent, and an excipient, wherein the excipient can increase the rate of release of the agent from the drug core, or can increase the drug loading in the core without loss of desirable homogeneity of the agent within the core, or can improve retention of the agent in the eye or in tear fluid, or can increase corneal penetration of the agent into the eye.
