Abstract: The present disclosure is directed to chemically-stable and pharmaceutically acceptable sildenafil oral spray formulations for the treatment of diseases such as pulmonary arterial hypertension and/or SSRI-induced sexual dysfunction, wherein the oral spray formulation has a pH of about 1.5 to less than 3.0. The present disclosure is also directed to methods for treating diseases such as pulmonary arterial hypertension and/or SSRI-induced sexual dysfunction.

Abstract: Buccal aerosol sprays or capsules using polar and non-polar solvents have now been developed which provide ondansetron for rapid absorption through the oral mucosa, resulting in fast onset of effect. The buccal polar compositions of the invention comprise formulation I: aqueous polar solvent, ondansetron, and optional flavoring agent; formulation II: aqueous polar solvent, ondansetron, optionally flavoring agent, and propellant; formulation III: non-polar solvent, ondansetron, and optional flavoring agent; formulation IV: non-polar solvent, ondansetron, optional flavoring agent, and propellant; formulation V: a mixture of a polar solvent and a non-polar solvent, ondansetron, and optional flavoring agent; formulation VI: a mixture of a polar solvent and a non-polar solvent, ondansetron, optional flavoring agent, and propellant.
