  • Patent number: 7879805
    Abstract: A stabilized pharmaceutical composition in the form of a lyophilized product to be later reconstituted to generate an aqueous drug product is described herein. The therapeutically active ingredient in the form of a peptide of sequence TDLQERGDNDISPFSGDGQPFKD is stabilized with a buffer, carbohydrate stabilizer, a nonionic bulking agent and a surfactant to facilitate reconstitution. The preferred preparation contains a peptide of the sequence TDLQERGDNDISPFSGDGQPFKD, histidine buffer, mannitol or glycine, sucrose and/or Polysorbate 20. This combination of excipients has demonstrated exceptional stability as a lyophilized product when stored at the elevated temperature of 40° C. for at least 6 months and for at least 3 Months at 50° C. The lyophilized mixture thus formed is reconstituted to a high peptide concentration without apparent loss of stability of the peptide.

  • Publication number: 20090163413
    Abstract: Dental products such as toothpastes, mouthwash and dental floss are disclosed which products are enhanced by having dissolved, dispersed or coated thereon a compound which promotes bone growth. Preferred compounds are peptide sequences comprising 10 to 50 amino acids are disclosed. The sequences are characterized by containing an integrin binding motif such as RGD sequence and the remainder of amino acids contiguous with the RGD sequence in matrix extracellular phosphoglycoprotein. The sequences may be formulated for dispersed in toothpaste or a mouthwash and administered to enhance bone/tooth growth. When the dental products are used repeatedly over time they enhance good dental health.

  • Publication number: 20090062201
    Abstract: Peptide sequences comprising 10 to 50 amino acids are disclosed. The sequences are characterized by containing at least one of an integrin binding motif such as an RGD sequence, a glycosaminoglycan binding motif, and a calcium binding motif, and the remainder of amino acids contiguous with the RGD sequence in matrix extracellular phosphoglycoprotein. The sequences may be formulated for injection or dispersed in toothpaste or a mouthwash or gum patch and administered to enhance bone/tooth growth and/or reduce excessive urinary phosphate loss from the body.
