The present invention is directed generally to systems, devices and methods for direct delivery of agents, e.g., pharmaceutical agents, to target spinal and neuronal anatomies, e.g., the dorsal root ganglia (DRG), for the treatment of various disorders, particularly pain and pain related disorders, such as chronic itch, sensory disorders, multiple sclerosis, post-herpetic neuralgia and the like. The system, devices and methods of the invention encompass the agents to be delivered to the target anatomy alone or in combination with electrical stimulation. The delivery device and systems and methods as disclosed herein place the distal end of the delivery element, which comprises at least one agent delivery structure, and optionally at least one electrode, in close proximity, or in contact with or next to the target spinal anatomy, e.g., DRG. A variety of agents can be delivered using the device, including sodium channel blockers, biologics, neuroinflammatory modulators, toxins etc., to selectively neuromodulate the neurons. Agent delivery and/or electrical stimulation can be automated and/or can be controlled automatically or by a pre-determined program, or by a patient control pump (PCA).

Prophylactic treatment methods are provided for protection of individuals and/or populations against infection from airborne pathogens. In particular, prophylactic treatment methods are provided comprising administering a sodium channel blocker or pharmaceutically acceptable salts thereof to one or more members of a population at risk of exposure to or already exposed to one or more airborne pathogens, either from natural sources or from intentional release of pathogens into the environment.

The present invention relates to methods and compositions for treating diseases ameliorated by increased mucociliary clearance and mucosal hydration by administering an effective amount of a sodium channel blocker as defined herein and an osmolyte to a subject to a subject in need of increased mucociliary clearance and mucosal hydration.

The present invention provides compositions and methods for enhancing cognitive function and synaptic plasticity. According to the method, Ca⁺⁺ influx into excitatory neurons (nerve cells) is decreased by treatment with a number of different agents including divalent cations (e.g., Mg⁺⁺), GABA_B agonists, GABA_A agonists, calcium channel blockers, and/or compounds that decrease action potential firing such as sodium channel blockers. Decreasing Ca⁺⁺ influx results in increased synaptic plasticity and enhanced cognitive function. In particular, decreasing Ca⁺⁺ influx associated with uncorrelated neural activity results in long-lasting increases in synaptic plasticity and cognitive function. This is achieved by administration of agents that cause a voltage-dependent block of NMDA receptors (e.g., divalent cations such as Mg⁺⁺) or by administration of GABA_B agonists such as baclofen. The invention further provides screening methods useful in identifying compounds that enhance synaptic plasticity and cognitive function.

Controlled release of pharmaceutical agents using microspheres or other controlled release systems are used to treat disease state characterized by aberrant electrical activity in excitable tissue. For the treatment of epilepsy, agents useful in the treatment of epilepsy may be delivered to the patient at the site of seizure origin to control seizure activity in a time release manner. The inventive system may also be useful in the treatment of cardiac arrhythmias and pre-term labor. Particularly useful pharmaceutical compositions comprising a site 1 sodium channel blocker are also provided.

The present invention relates to sodium channel blockers. The present invention also includes a variety of methods of treatment using these inventive sodium channel blockers.

The invention relates to substituted pyridine compounds of Formula I: (I) and the pharmaceutically acceptable salts, prodrugs, and solvates thereof, wherein R^1a, R^1b, R^2a, R^2b, R^2c, A¹, A², and X are defined as set forth in the specification. The invention is also directed to the use of compounds of Formula I to treat a disorder responsive to the blockade of sodium channels. Compounds of the present invention are especially useful for treating pain.

Methods of treating or preventing chronic pain or convulsion are disclosed by administering to an animal a sodium channel blocker and at least one of gabapentin and pregabalin. Also disclosed are pharmaceutical compositions and kits for the treatment or prevention of chronic pain or convulsion.

The present invention relates to sodium channel blockers. The present invention also includes a variety of methods of treatment using these inventive sodium channel blockers.
