Abstract: The present invention pertains to certain N-alkylcarbonyl-D-amino acid hydroxylalkyl esters (NACHE), including, for example, (R)-2-[((1R,2S,5R)-2-isopropyl-5-methyl-cyclohexanecarbonyl)-amino]-propionic acid 3-hydroxy-propyl ester, and compositions comprising such compounds, that target sensory elements on nerve fibers and which are usefully administered to refresh and cool the skin and mucous membranes. This disclosure generally relates to menthol-like cooling compounds, which do not have the smell, taste, or short duration of action of menthol. These compounds are designed for delivery onto the surfaces of the oral cavity, upper respiratory tract and skin. These compositions produce refreshing and cooling sensations and are expected to inhibit the perception of cough stimuli, itch, pain, and discomfort from the body's surfaces. In the oral cavity these compositions produce refreshing cooling without adverse effects on taste.

Abstract: The present invention relates to methods and devices for treating sensory discomfort in the upper airways of a human; treating sensory discomfort in the oropharynx of a human; alleviating pain from pharyngitis in a human; alleviating cough in a human; and ameliorating the symptoms and signs of asthma, dyspnea, sleep apnea, snoring or chronic obstructive pulmonary disease in a human. According to the invention, an active compound is delivered, preferably selectively delivered, to the oropharynx, preferably the oropharyngeal surfaces, more preferably the lower retropalatal oropharynx (LRO) of the patient. According to the invention, the active compound is a compound of the following formula, wherein R is C2 to C4 hydroxyalkyl or polyhydroxyalkyl.

Abstract: This disclosure generally relates to chemicals that affect sensory processes. More particularly, this present invention relates to peripheral sensory compounds (including, e.g., 2-Isopropyl-5-methyl-cyclohexanecarboxylic acid [2?-hydroxy-2?-(3?-hydroxy-phenyl)-ethyl]-N-methyl-amide) that are useful in sensory refreshment, inhibit the perception of itch and pain, and alleviation of skin irritation, itch, and pain. These compositions have surprising pharmacokinetic properties that allow a prolonged duration of pharmacological actions and may be administered topically or systemically.

Abstract: The present invention generally relates to refreshing, soothing, and cooling compounds that affect sensory processes. More particularly, the present invention pertains to certain N-alkylcarbonyl-amino acid ester and N-alkylcarbonyl-amino lactone compounds as described herein; compositions and articles comprising such compounds; and methods of treatment, for example, methods of alleviating the discomforts of irritation, itch, and pain in the skin and in the linings of the oral cavity and upper respiratory tract, for example, in methods of treatment of cough and/or asthma.
