Definitions

  • Alzheimer's disease is a neurodegenerative disease of the brain leading to severely impaired cognition and functionality. This disease leads to progressive regression of memory and learned functions. Alzheimer's disease is a complex disease that affects cholinergic neurons, as well as serotonergic, noradrenergic and other central neurotransmitter systems. Manifestations of Alzheimer's disease extends beyond memory loss and include personality changes, neuromuscular changes, seizures, and occasionally psychotic features.
  • Inhibitors of cyclooxygenase-2 are a sub-class of the class of drugs known as non-steroidal antiinflammatory drugs (NSAIDs).
  • NSAIDs non-steroidal antiinflammatory drugs
  • the NSAIDs are active in reducing the prostaglandin-induced pain and swelling associated with the inflammation process but are also active in affecting other prostaglandin-regulated processes not associated with the inflammation process.
  • use of high doses of most common NSAIDs can produce severe side effects, including life threatening ulcers, that limit their therapeutic potential.
  • An alternative to NSAIDs is the use of corticosteroids, which have even more drastic side effects, especially when long term therapy is involved.
  • Previous NSAIDs have been found to prevent the production of prostaglandin by inhibiting enzymes in the human arachidonic acid/prostaglandin pathway including the enzyme cyclooxygenase (COX).
  • COX cyclooxygenase
  • COX-2 inhibitors Many compounds which have activity as COX-2 inhibitors have been identified, including rofecoxib (VIOXX®), etoricoxib (ARCOXIATM), celecoxib (CELEBREX®), valdecoxib, parecoxib, and much research continues in this area.

  • the active agents of the present method may be administered in divided doses, for example two or three times daily, a single daily dose of each of the HMG-CoA RI and the COX-2 inhibitor is preferred, with a single daily dose of both agents in a single pharmaceutical composition being most preferred.
  • the instant invention also encompasses a process for preparing a pharmaceutical composition comprising combining the HMG- CoA RI and the COX-2 inhibitor with a pharmaceutically acceptable carrier, as well as the pharmaceutical composition which is made by combining the HMG-CoA RI and the COX-2 inhibitor with a pharmaceutically acceptable carrier.
  • a therapeutically effective amount of an HMG-CoA RI and a COX-2 inhibitor can be used together for the preparation of a medicament useful for treating or preventing Alzheimer's disease.
  • the medicament may be comprised of a COX-2 inhibitor in combination with about 1 mg to 200 mg of an HMG-CoA RI, or more particularly about 5 mg to 160 mg of the HMG-CoA RI. More specific amounts of HMG-CoA RI which may be used in the medicament preparation include 1 mg, 5 mg, 10 mg, 20 mg, 40 mg, 80 mg, and 160 mg, as well as sub-milligram amounts of HMG-CoA RI's which have sufficient potency at such levels.
  • the medicament may be comprised of an HMG-CoA RI in combination with about 0.1 to 20 mg of a COX-2 inhibitor.
  • the instant invention also encompasses the use of an HMG- CoA reductase inhibitor for the preparation of a medicament for the combined use with a cyclooxygenase-2 inhibitor for treating Alzheimer's disease; and the use of a cyclooxygenase-2 inhibitor for the preparation of a medicament for the combined use with an HMG-CoA reductase inhibitor for treating or preventing Alzheimer's disease.
  • the medicament or pharmaceutical combination comprised of the HMG-Co RI and the COX-2 inhibitor may also be prepared with one or more additional active agents, such as those described supra.
