An intranasal spray device contains a composition for the intranasal delivery of fentanyl or a pharmaceutically acceptable salt thereof to an animal includes an aqueous solution of fentanyl or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable additive selected from (i) a pectin and (ii) a poloxamer and chitosan or a salt or derivative thereof; provided that when the composition comprises a pectin it is substantially free of divalent metal ions; and which, in comparison to a simple aqueous solution of fentanyl administered intranasally at the same dose, provides a peak plasma concentration of fentanyl (C) that is from 10 to 80% of that achieved using a simple aqueous solution of fentanyl administered intranasally at an identical fentanyl dose. A method for treating or managing pain by intranasally administering the composition is also disclosed.

Intranasal spray device containing pharmaceutical composition

An intrasnal spray device contains a composition for the intranasal delivery of fentanyl or a pharmaceutically acceptable salt thereof to an animal includes an aqueous solution of fentanyl or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable additive selected from (i) a pectin and (ii) a poloxamer and chitosan or a salt or derivative thereof; provided that when the composition comprises a pectin it is substantially free of divalent metal ions; and which, in comparison to a simple aqueous solution of fentanyl administered intranasally at the same dose, provides a peak plasma concentration of fentanyl (C) that is from 10 to 80% of that achieved using a simple aqueous solution of fentanyl administered intranasally at an identical fentanyl dose. A method for treating or managing pain by intranasally administering the composition is also disclosed.

A composition for intranasal delivery of a drug comprising: includes: (i) the drug; and (ii) a non-aqueous vehicle containing (a) propylene glycol and at least one additional solvent selected from N-methylpyrrolidone, propylene carbonate, dimethyl sulfoxide and at least one propylene glycol fatty acid ester; (b) from about 40 to 100% by volume of N-methylpyrrolidone; or (c) from about 40 to 100% by volume of dimethyl sulfoxide (DMSO).

Non-aqueous pharmaceutical composition

A composition for the intranasal delivery of fentanyl or a pharmaceutically acceptable salt thereof to an animal includes an aqueous solution of fentanyl or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable additive selected from (i) a pectin and (ii) a poloxamer and chitosan or a salt or derivative thereof; provided that when the composition comprises a pectin it is substantially free of divalent metal ions; and which, in comparison to a simple aqueous solution of fentanyl administered intranasally at the same dose, provides a peak plasma concentration of fentanyl (C) that is from 10 to 80% of that achieved using a simple aqueous solution of fentanyl administered intranasally at an identical fentanyl dose. A method for treating or managing pain by intranasally administering the composition is also disclosed.

Method of managing or treating pain

A powder composition for intranasal delivery includes a benzodiazepine drug and chitosan, a salt of chitosan, a derivative of chitosan or a salt of a derivative of chitosan.

Pharmaceutical powder compositions

The present invention provides a solid composition for oral administration comprising:

Pharmaceutical treatment process using chitosan or derivative thereof

There is provided a powder formulation for nasal delivery including a protein having a molecular weight of 10 kDa or greater and chitosan or a derivative thereof or a salt of chitosan or a salt of a derivative of chitosan. Preferably the protein is human growth hormone.

Pharmaceutical formulations for intranasal administration of protein comprising a chitosan or a derivative thereof

Sustained release pharmaceutical compositions contain a drug; microcrystalline cellulose; a diluent (such as starch); a glidant (such as talc); and one or more of ethylcellulose, stearic acid and a salt of stearic acid. Preferred drugs include those that exhibit a low degree of solubility combined with a high potency, particularly thyroid hormones, such as liothyronine.

Pharmaceutical compositions

The present invention provides compositions for the intranasal administration of zolpidem or a pharmaceutically acceptable salt thereof. Preferred compositions of the invention are in the form of aqueous solutions. Optionally the compositions of the invention comprise a cyclodextrin and/or chitosan, a salt or derivative thereof or a salt of a derivative of chitosan. The compositions can be used for the treatment or prevention insomnia or the treatment of neurological disorders such as those arising from brain trauma, stroke and spinocerebellar ataxia or in the treatment of Parkinson's disease.

Intranasal compositions

Compositions are provided for the intranasal administration of granisetron or a pharmaceutically acceptable salt thereof. Preferred compositions are in the form of an aqueous solution. Optionally, the compositions comprise chitosan, a salt or derivative thereof or a salt of a derivative of chitosan. The compositions can be used for the treatment or prevention of nausea and/or vomiting.

Method of intranasal administration of granisetron

Liquid pharmaceutical compositions comprising at least one thyroid hormone, ethanol, a pH adjusting agent, and water are disclosed. The compositions may be delivered by a metered dosage delivery system such as an aerosol or pump-action spray, and are useful in the treatment of disorders associated with an impairment of thyroid hormone function in animals including human beings.

Liquid pharmaceutical compositions comprising thyroid hormones

There is disclosed a liquid pharmaceutical composition comprising a therapeutic agent which comprises: one or more thyroid hormone or hormones; from about 40% to about 96% ethanol by volume; a pH adjusting agent so that the measured pH of the composition is from about 9 to about 12; and from about 4% to about 50% water by volume; which has utility in the treatment of disorders associated with an impairment of the thyroid hormone function in animals including human beings. The liquid composition may be delivered by a metered dosage delivery system such as an aerosol or pump-action spray.

The methane sulphonate salt of morphine and compositions thereof have medicinal uses, particularly in the treatment of pain. Compositions comprising a methane sulphonate salt of an opioid analgesic also have medicinal uses, adapted for nasal delivery.
