The present invention provides pharmaceutical compositions and methods for the instillation of lipid vehicles comprised of liposomes containing sphingomyelin or sphingomyelin metabolites to prevent, manage, ameliorate and/or treat disorders involving neuropathic pain and aberrant muscle contractions, such as what occurs in bladder hyperactivity disorders such as interstitial cystitis (IC) in animals or humans in need thereof. Also provided is a liposome-based delivery of drugs, e.g., antibiotics, pain treatments and anticancer agents, to the bladder, genitourinary tract, gastrointestinal system, pulmonary system and other organs or body systems. In particular, liposome-based delivery of vanilloid compounds, such as resiniferatoxin, capsaicin, or tinyatoxin and toxins, such as botulinum toxin is provided for the treatment of bladder conditions, including pain, inflammation, incontinence and voiding dysfunction.

Sphingomyelin liposomes for the treatment of hyperactive bladder disorders

The invention relates to methods of using Cav2.2 subunit calcium channel modulators to treat painful and non-painful lower urinary tract disorders and the related genitourinary tract disorders vulvodynia and vulvar vestibulitis in normal and spinal cord injured patients.

Methods of using ziconotide to treat overactive bladder

The invention relates to methods of using Cav2.2 subunit calcium channel modulators, particularly thiazolidinone, oxazolidinone, and imidazolone derivatives, to treat lower urinary tract and related disorders.

Thiazolidinone, oxazolidinone, and imidazolone derivatives for treating lower urinary tract and related disorders

A method is provided for using Cav2.2 subunit calcium channel modulators to treat non-inflammatory gastrointestinal tract disorders.

Methods of treating non-inflammatory gastrointestinal tract disorders using Cav2.2 subunit calcium channel modulators

The invention relates to a method of treating at least one symptom of a lower urinary tract disorder in a subject in need of treatment wherein the symptom is selected from the group consisting of urinary frequency, urinary urgency, urinary urge incontinence, nocturia and enuresis. The method comprises administering to a subject in need of treatment a therapeutically effective amount of a compound that has 5-HTreceptor antagonist activity and NorAdrenaline Reuptake Inhibitor (NARI) activity. The invention further relates to a method of treating at least one symptom of a lower urinary tract disorder in a subject in need of treatment wherein the symptom is selected from the group consisting of urinary frequency, urinary urgency, urinary urge incontinence, nocturia and enuresis, comprising coadministering to said subject a first amount of a 5-HTantagonist and a second amount of a NARI, wherein the first and second amounts together comprise a therapeutically effective amount or are each present in a therapeutically effective amount.

[object Object]

The present invention relates to compositions and methods for the administration of lipid-based vehicles to treat various disorders, including bladder inflammation, infection, dysfunction, and cancer. In various aspects, the compositions and methods of the invention are useful for prolonged delivery of drugs, e.g., antibiotics, pain treatments, and anticancer agents, to the bladder, genitourinary tract, gastrointestinal system, pulmonary system, and other organs or body systems. In particular, the present invention relates to liposome-based delivery of vanilloid compounds, such as resiniferatoxin, capsaicin, or tinyatoxin, and toxins, such astoxin, for the treatment of bladder conditions, including pain, inflammation, incontinence, and voiding dysfunction. Further related are methods of using these vehicles alone or in conjunction with antibodies, e.g., uroplakin antibodies, to improve duration of liposome attachment, and provide a long-term intravesical drug delivery platform. The present invention specifically relates to antibody-coated liposomes that are useful for targeting specific receptors for drug, peptide, polypeptide, or nucleic acid delivery. In one particular aspect, the present invention relates to liposomes coated with antibodies against nerve growth factor (NGF) receptor and containing NGF antisense nucleic acids, which are used as a treatment for neurogenic bladder dysfunction.

Application of lipid vehicles and use for drug delivery

The invention relates to methods of using sodium channel modulators, particularly TTX-R sodium channel modulators and/or activity dependent sodium channel modulators to treat a gastrointestinal tract disorders, particularly inflammatory bowel disorders and irritable bowel syndrome.
