The use of phosphodiesterase 5 (PDE5) inhibitors for treatment of schizophrenia is described. Suitable PDE5 inhibitors for use for treatment of schizophrenia include sildenafil, vardenafil, tadalafil, E-8010, zaprinast, and E-4021. In one embodiment, for example, a method is described for treating schizophrenia in a patient which comprises treating the patient with an effective amount of a PDE5 inhibitor, or a pharmaceutically acceptable salt, solvate, or composition thereof. The PDE5 inhibitor may be administered orally. The PDE5 inhibitor may also be administered together with one or more conventional antipsychotic medications such as risperidone, olanzapine, quetiapine, ziprasidone, aripiprazole, clozapine, haloperidol, and fluphenazine.

The present invention is directed to a method of screening for a therapeutic agent useful for treating pulmonary hypertension comprising: contacting an erythrocyte with a candidate therapeutic agent; and detecting a presence or absence of erythrocyte-derived adenosine triphosphate, wherein a greater erythrocyte-derived adenosine triphosphate level indicates the candidate therapeutic agent has greater activity in treating pulmonary hypertension. Additionally, the present invention is directed to methods of treating pulmonary arterial hypertension by stimulating ATP release from erythrocytes through co-administration to a subject in need thereof an amount of a PDE5 inhibitor compound, and an amount of a prostacyclin compound.

The invention relates generally to combination therapies comprising an endothelin A receptor (ET_A) antagonist and a phosphodiesterase 5 (PDE5) inhibitor, pharmaceutical compositions comprising ET_A antagonist and PDE5 inhibitor and methods of treating various disorders comprising administering an ET_A antagonist and a PDE5 inhibitor. In particular, the combination therapies and pharmaceutical compositions are useful for the treatment and/or prevention of cardiac disorders such as pulmonary arterial hypertension (PAH).

The present invention encompasses oral formulations of a PDE5 inhibitor which provide rapid disintegration after introduction to the oral cavity, followed by buccal and/or sublingual absorption. The orally disintegrating formulations can be in a variety of dosage forms including lingual strip, sublingual strip, oral mist, rapidly disintegrating tablet, lyophilized wafer, granulated particles and gum. The formulations can include an extended release component that allows the PDE5 inhibitor to be swallowed for gastrointestinal absorption. Combination therapies with a second pharmaceutical agent known to cause a PDE5-treatable condition as a side effect, such as erectile dysfunction, are also described.

The PDE5 inhibitor of the following chemical structure is particularly favored for these formulations:

Methods useful for reducing or preventing non-alcoholic steatohepatitis or hepatic steatosis are provided herein. Such methods may comprise administering to a subject in need thereof a sirtuin pathway activator and/or PDE5 inhibitor alone or in combination with an amount of a branched amino acid in free amino acid form, or a metabolite thereof. Also provided herein are compositions and kits for practicing any of the methods described herein.

The invention relates to the combined administration of a PDE4 inhibitor and a PDE5 inhibitor for the treatment of a disease in which phosphodiesterase 4 (PDE4) and/or phosphodiesterase 5 (PDE5) is detrimental.

Improved delivery systems and delivery methods for supporting and promoting healthy sexual function, for preventing sexual dysfunction, or for treatment of sexual dysfunction. A compositions including one or more cGMP-specific PDE5 inhibitors and/or dopaminergic agonists is administered in the form of a breath-care strip, mint or lozenge, or a food or beverage product. The cGMP-specific PDE5 inhibitor comprises an ingredient selected from the group consisting of sophoflavescenol, vardenafil, tadalafil, and sildenafil. The dopaminergic agonist comprises apomorphine. Vitex agnus-castus extract, and one or more of lipoic acid, L-Arginine, folic acid, trimethylglycine, policosanol, carnitine, biotin, and acetyl L-Carnitine may also be included in the delivery vehicle.

The present invention relates to the use of a combination of a PDE5-inhibitor and testosterone for the preparation of a medicament for the treatment of Female Sexual Dysfunction.

The present invention relates to methods of treating multidrug resistance in cancerous cells with phosphodiesterase (PDE) inhibitors, e.g., PDE5 inhibitors. More specifically, the invention relates to methods of treating multidrug resistance that arises, e.g., during administration of chemotherapeutic/antineoplastic (anticancer) agents for treatment of cancer, with a PDE5 inhibitor (e.g., sildenafil, vardenafil, and tadalafil). The invention also relates to methods of treating cancer, e.g., multidrug resistant cancer, using a PDE5 inhibitor in combination with an antineoplastic therapeutic agent. Further, the invention relates to pharmaceutical compositions for treating multidrug resistant cancers comprising a PDE5 inhibitor, or a combination of a PDE5 inhibitor and an antineoplastic agent.

The invention relates to the combined administration of a pulmonary surfactant and a PDE5 inhibitor for the treatment of a disease in which pulmonary surfactant malfunction and/or phosphodiesterase 5 (PDE5) activity is detrimental.

The use of sGC stimulators, sGC activators alone, or in combination with PDE5 inhibitors for the prevention and treatment of fibrotic diseases, such as systemic sclerosis, scleroderma, and the concomitant fibrosis of internal organs.

To provide a novel pharmaceutical composition for alleviating pain or spasticity in a patient suffering from spinal cord injury. The present invention relates to a method for alleviating pain or spasticity in a patient suffering from spinal cord injury comprising administering to the patient an effective amount of cGMP PDE5 inhibitor, to a pharmaceutical composition comprising such an effective amount of the inhibitor, and to a use of the inhibitor in the manufacture of such a pharmaceutical composition.

The present invention relates to the development of improved methods for treating erectile dysfunction associated with diabetes. Significantly, such dosing regimens can be combined with established methods for treating sexual dysfunction, including PDE5 inhibitors such as those sold under the trademark VIAGRA® to provide for significantly improved efficacy compared to the PDE5 inhibitor alone.

The present invention relates to soluble guanylate cyclase (sGC) and to phosphodiesterases (PDEs) and the pharmacology of sGC stimulators, sGC activators and PDE inhibitors. More particularly, the invention relates to the use of sGC stimulators and sGC activators in combination with PDE5 inhibitors for preparation of medicaments for the treatment of Cystic Fibrosis (CF).
