Pharmaceutical formulations with a tropomyosin-related kinase inhibitor ('Trk inhibitor') are disclosed. The pharmaceutical formulations comprise 3-(3-methoxy-4-((4-methoxybenzyl)oxy)benzyl)-6-(1-methyl-1H-pyrazol-4-yl)-3H-imidazo[4,5-b]pyridin-2-amine in microcrystalline suspension formulations in its monohydrate form, which shows improved characteristics over the anhydrate form, and in extended release formulations. The extended release pharmaceutical formulations comprise 3-(3-methoxy-4-((4-methoxybenzyl)oxy)benzyl)-6-(1-methyl-1H-pyrazol-4-yl)-3H-imidazo[4,5-b]pyridin-2-amine-loaded microspheres.

Gel-forming macromers including at least four polymeric blocks, at least two of which are hydrophobic and at least one of which is hydrophilic, and including a crosslinkable group are provided. The macromers can be covalently crosslinked to form a gel on a tissue surface in vivo. The gels formed from the macromers have a combination of properties including thermosensitivity and lipophilicity, and are useful in a variety of medical applications including drug delivery and tissue coating.

Multiblock biodegradable hydrogels for drug delivery and tissue treatment

Hyaluronic acid and polyalkylene glycol (PAG) based materials have been found to exhibit a synergistic interaction, in which the viscosity of the mixture is more than twice as high as the viscosity expected from the viscosity of the individual components. The mixture otherwise has similar properties to those of its constituents, and in particular will crosslink to form covalently crosslinked gels if the PEG carries crosslinkable groups. The viscous formulation adheres well to tissue, and has applications as a tissue sealant and in tissue coating, prevention of adhesions, cell immobilization, regeneration of cartilage, bone and other tissue, as well as in controlled delivery of hyaluronic acid to sites in the body. Related materials exhibit similar effects.

Polyalkylene glycol viscosity-enhancing polymeric formulations

Methods for the simple, reliable application and local controlled release of selected anti-arrhythmia drugs from a hydrogel applied to or polymerized on the tissues of the heart or its vessels, especially in conjunction with cardiac bypass or other cardiac surgery, have been developed. The anti-arrhythmia drugs are incorporated into hydrogels that biodegrade and adhere to the tissues to which the anti-arrhythmic drugs are to be delivered. The hydrogels may be formed in vitro or in vivo. In a preferred embodiment, the drugs are effective to lengthen atrial effective refractory period. A particularly preferred drug is amiodarone.

Controlled release of anti-arrhythmic agents

A method of controlling hemostasis by applying a hemostatic agent in a tissue sealant composition. The tissue sealant is a biodegradable, biocompatible synthetic polymer that may not intrinsically possess strong hemostatic properties. Inclusion of a hemostatic material in the tissue sealant can control bleeding at the site and may also provide improved adherence of the sealant to tissue and provide shorter healing times.

Hemostatic tissue sealants

A formulation is disclosed comprising a pharmaceutically acceptable admixture of an osteogenic protein and a sponge of porous particulate polymer matrix. The sponge may be prepared by treating the porous particulate polymer matrix with a suitable fusing material such as ethanol and a surfactant such as a polysorbate.
