DRUG CORES FOR SUSTAINED RELEASE OF THERAPEUTIC AGENTS

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.

Ionically modified silicones, compositions, and medical devices formed therefrom

A hydrophilic silicone, compositions comprising the same, and articles comprising the same are shown and described herein. The hydrophilic silicone is an ionically modified silicone compound wherein the compound has a net neutral charge. The hydrophilic silicone compounds may be provided as part of a composition, e.g., a composition suitable for forming a hydrogel, which may be employed to form a film material and even an article (e.g., in a contact lens).

Radioluminescent phototherapy eye device

Embodiments of the present disclosure are directed to a phototherapy eye device. In an example, the phototherapy eye device includes a number of radioluminescent light sources and an anchor. Each radioluminescent light source includes an interior chamber coated with phosphor material, such as zinc sulfide, and containing a radioisotope material, such as gaseous tritium. The volume, shape, phosphor material, and radioisotope material are selected for emission of light at a particular wavelength and delivering a particular irradiance on the retina (when implanted in an eyeball). The wavelength is in the range of 400 to 600 nm and the irradiance is substantially 10.sup.9 to 10.sup.11 photons per second per cm.sup.2.

Glaucoma treatment device

Methods and devices are adapted for implanting into the eye. An incision is formed in the cornea of the eye and a shunt is inserted through the incision into the anterior chamber of the eye. The shunt includes a fluid passageway. The shunt is passed along a pathway from the anterior chamber through the scleral spur of the eye into the suprachoroidal space and positioned in a first position such that a first portion of the fluid passageway communicates with the anterior chamber and a second portion of the fluid passageway communicates with the suprachoroidal space to provide a fluid passageway between the suprachoroidal space and the anterior chamber.

Ophthalmically therapeutic materials, such as liquid-containing compositions and polymeric drug delivery systems, include a therapeutic component that includes an Glucocorticoid Derivative which, upon delivery to the posterior segment of a mammalian eye, does not significantly diffuse to the anterior segment of said eye. Methods of making and using the present materials are also described.

Pharmaceutical preparation containing pyridyl aminoacetic acid compound

The present invention aims to find a pharmaceutical preparation which treats or prevents glaucoma or ocular hypertension and is effective for patients with inadequate efficacies of glaucoma or ocular hypertension therapeutic agents. It has been found that omidenepag, an ester thereof, or a salt thereof has an excellent intraocular pressure lowering efficacy on patients with inadequate efficacies of other glaucoma or ocular hypertension therapeutic agents. Therefore, the omidenepag, the ester thereof, or the salt thereof of the present invention is useful as a pharmaceutical preparation which can treat or prevent glaucoma or ocular hypertension even in patients with inadequate efficacies of other glaucoma or ocular hypertension therapeutic agents.

Drug formulations, devices and methods are provided to deliver biologically active substances to the eye. The formulations are delivered into scleral tissues adjacent to or into the suprachoroidal space without damage to the underlying choroid. One class of formulations is provided wherein the formulation is localized in the suprachoroidal space near the region into which it is administered. Another class of formulations is provided wherein the formulation can migrate to another region of the suprachoroidal space, thus allowing an injection in the anterior region of the eye in order to treat the posterior region.

Biodegradable ocular implant

Provided is a biodegradable ocular implant for sustained drug delivery, including a first layer comprising a first biodegradable polymer, wherein the first layer contains a drug dispersed or dissolved therein. A multi-layered biodegradable ocular implant is also disclosed.

Ocular composition and method

An ocular composition can include a polymer matrix and an antibiotic dispersed in the polymer matrix. The polymer matrix can contain a thiolated hyaluronic acid moiety cross-linked to a second moiety. The composition can be configured for placement in or on an eye of a subject to provide controlled release of the antibiotic to the eye. A method of treating or preventing an ocular disease can include providing an ocular composition and applying the ocular composition to a surface of an eye of a subject to provide controlled release of the antibiotic to the eye. The ocular composition can include a polymer matrix and an antibiotic dispersed in the polymer matrix. The polymer matrix can include a thiolated hyaluronic acid moiety cross-linked to a second moiety.

DRUG DELIVERY METHODS, STRUCTURES, AND COMPOSITIONS FOR NASOLACRIMAL SYSTEM

An implant for insertion into a punctum of a patient comprises a body. The body has a distal end, a proximal end, and an axis therebetween. The distal end of the body is insertable distally through the punctum into the canalicular lumen. The body comprises a therapeutic agent included within an agent matrix drug core. Exposure of the agent matrix to the tear fluid effects an effective therapeutic agent release into the tear fluid over a sustained period. The body has a sheath disposed over the agent matrix to inhibit release of the agent away from the proximal end. The body also has an outer surface configured to engage luminal wall tissues so as to inhibit expulsion when disposed therein. In specific embodiments, the agent matrix comprises a non-bioabsorbable polymer, for example silicone in a non-homogenous mixture with the agent.
