Hypotonic hydrogel formulations for enhanced transport of active agents at mucosal surfaces
Hypotonic formulations of hydrogel forming polymers, preferably poloxamers, have been developed for enhanced delivery through mucosa of therapeutic, diagnostic, prophylactic or other agents, to epithelial tissues, especially those having a mucosal coating. The polymers are administered at a concentration above, at or less than their critical gelling concentration (CRC) under isotonic conditions. The hypo tonicity of the formulation is adjusted so that the polymer gels at the lower concentration. A Poloxamer gel administered into the vagina or colorectal at its CRC will form a “plug” of gel in the lumen.
HYDROALCOHOLIC SYSTEM FOR NAIL TREATMENT
A pharmaceutical composition related to drug delivery systems for the treatment of nail diseases includes (i) poloxamer 407, (ii) at least one penetration enhancer, and (iii) at least one solubilizing agent selected from the group consisting of cyclodextrins, hydrophilic polymers and mixtures thereof. The composition also includes (iv) at least one biologically active substance and (v) a vehicle comprising water and a C.sub.1-C.sub.3 alcohol or mixtures thereof.
Flavonoid-based composition for pharmaceutical, nutritional or cosmetic use having potentiated antioxidant action
The invention relates to a composition for pharmaceutical or nutritional or cosmetic use, formulated for oral or topical use and possessing antioxidant activity against free radicals, comprising: a) a Vitis vinifera seed, or seed and leaf, extract containing a combination of the flavonoids catechin and quercetin in a molar ratio in a range from 6:1 to 3:1, respectively, or a′) a Vitis vinifera seed, or seed and leaf, extract containing a combination of the flavonoids catechin and quercetin in a molar ratio in a range from 7:1 to 4:1, respectively, or a″) a mixture of Vitis vinifera extracts a) and a′), or a′″) a mixture of catechin and quercetin in a molar ratio in a range from 7:1 to 3:1, respectively, together with b) an olive, Olea europaea L, leaf extract having a hydroxytyrosol content in a range from 1% to 30% by weight of the extract, or b′) hydroxytyrosol in an amount equal to that contained in the b) extract.
Parenteral Formulations of Dopamine Agonists
This invention relates to stable pharmaceutical compositions for parenteral administration comprising dopamine agonists and peripheral acting agents useful for treatment of metabolic disorders or key elements thereof. The parenteral dosage forms exhibit long stable shelf life and distinct pharmacokinetics.
Tissue anchoring articles
Self-righting articles, such as self-righting capsules for administration to a subject, are generally provided. In some embodiments, the self-righting article may be configured such that the article may orient itself relative to a surface (e.g., a surface of a tissue of a subject). The self-righting articles described herein may comprise one or more tissue engaging surfaces configured to engage (e.g., interface with, inject into, anchor) with a surface (e.g., a surface of a tissue of a subject). In some embodiments, the self-righting article may have a particular shape and/or distribution of density (or mass) which, for example, enables the self-righting behavior of the article. In some embodiments, the self-righting article may comprise a tissue interfacing component and/or a pharmaceutical agent (e.g., for delivery of the active pharmaceutical agent to a location internal of the subject). In some cases, upon contact of the tissue with the tissue engaging surface of the article, the self-righting article may be configured to release one or more tissue interfacing components. In some cases, the tissue interfacing component is associated with a self-actuating component. For example, the self-righting article may comprise a self-actuating component configured, upon exposure to a fluid, to release the tissue interfacing component from the self-righting article. In some cases, the tissue interfacing component may comprise and/or be associated with the pharmaceutical agent (e.g., for delivery to a location internal to a subject).
AN ANTIMICROBIAL COMPOSITION FOR SELECTIVELY INHIBITING GROWTH OF P. ACNES BACTERIA
The present invention relates to a method and a composition to prevent or treat acne by selective inhibition of P. acnes bacteria. The method comprises treating skin with P. acnes phage-derived endolysins and nucleic acid molecules encoding the same C in combination with selective essential oils.
Molecular probes for detection and imaging of pancreatic cancer
Molecular probes for detecting and imaging pancreatic cancer are disclosed. The probes are modified benzoxanthene fluorophores, which are selectively taken up by pancreatic cancer cells, such as pancreatic ductal adenocarcinoma cells. Embodiments of the disclosed probes are useful for pancreatic cancer detection, therapeutic monitoring, and/or image-guided surgery.
NANOPARTICLES FOR DRUG DELIVERY TO BRAIN
Non-adhesive brain-permeable nanoparticles as large as 200 nm can diffuse rapidly in the brain ECS preferably made entirely of generally recognized as safe (GRAS) materials having neutral surface charge are described. Synergistic improvement of therapeutic distribution enabled by these non-adhesive, brain-permeable nanoparticles and osmosis-driven brain extracellular matrix (ECM) modulation will significantly enhance drug and gene delivery within the CNS, offering higher drug payload, improved drug loading efficiency, and significantly longer drug release durations.
Laser-assisted transdermal delivery of nanoparticulates and hydrogels
A method for laser assisted delivery of therapeutic agents includes selectively controlling a valve connected to a first channel disposed within a first sidewall of a nozzle, applying, through the first channel, a first substance to penetrate dermis to a predetermined depth, and administering, through a second channel unconnected with the valve and disposed within a second sidewall of the nozzle, a second substance to remove debris.
Compositions and methods utilizing poly(vinyl alcohol) and/or other polymers that aid particle transport in mucus
Particles, compositions, and methods that aid particle transport in mucus are provided. The compositions and methods may include, in some embodiments, modifying the surface coatings of particles including pharmaceutical agents that have a low water/aqueous solubility. In some embodiments, a surface coating includes a synthetic polymer having pendant hydroxyl groups on the backbone of the polymer, such as poly(vinyl alcohol) (PVA). Such compositions and methods can be used to achieve efficient transport of particles of pharmaceutical agents though mucus barriers in the body for a wide spectrum of applications, including drug delivery, imaging, and diagnostic applications. In certain embodiments, a pharmaceutical composition including such particles is well-suited for administration routes involving the particles passing through a mucosal barrier.
