Definitions

  • the invention relates to the field of practical medicine, namely, to the use of pharmaceutical compositions exhibiting a neurotropic action, alleviating manifestations of mental, behavioral, or cognitive disorders in cases of organic damage of various origin to the central nervous system.
  • AD Alzheimer’s disease
  • Dementia is the loss of cognitive functioning— thinking, remembering, and reasoning— and behavioral abilities to such an extent that it interferes with a person’s daily life and activities.
  • memory loss is mild, but with late-stage AD, individuals lose the ability to carry on a conversation and respond to their environment. If untreated, AD ultimately leads to death.
  • the speed of progression can vary, the typical life expectancy following diagnosis is three to nine years.
  • LTP long-term potentiation
  • LTP is mediated by the neurotransmitter glutamate via the N-Methyl-D-aspartic acid (NMDA) receptor.
  • NMDA receptors can be found diffusely throughout the brain. However, they densely populate the dendrites of pyramidal cells in the hippocampus and cortex (areas known to be involved in cognition, learning, and memory). In addition to the relationship between LTP and learning, elevated glutamate levels are associated with excito toxicity. Chronic low-dose administration of NMDA receptor agonists has been shown to induce apoptosis, while high doses induce necrosis. The activation of glutamate receptors has also been found to induce the release of glutamate.
  • AB plaques increase a neuron’s vulnerability to excitotoxicity.
  • AB plaques a pathological feature of AD, were found to induce depolarization of astrocytes, extracellular accumulation of glutamate, and intracellular deposition of Ca2+. Therefore, the glutamate-induced excitotoxicity pathway made an excellent target for the therapy of AD.
  • the glutamate released by neurons is metabolized or taken up by neighboring cells.
  • NMDA receptors act as a calcium [II] ion (Ca2+) channel that activates when bound by glycine, glutamate, and/or NMDA.
  • Ca2+ calcium [II] ion
  • Mg2+ magnesium [II] ion
  • NMDA receptor antagonists are looked to as possible neuroprotective agents and potential therapies for neurodegenerative disease.
  • NMDA antagonists are competitive antagonists and are not well tolerated by patients due to side effects, which can include hallucinations and schizophrenia-type symptoms.
  • the side effects likely result from the competitive antagonists blocking physiological functions of the NMDA receptor.
  • Memantine acts on activated NMDA receptors by binding to a site located in the channel of the receptor.
  • memantine will not cure AD or prevent the loss of these abilities at some time in the future. So AD has no current cure, and our effort is to find better ways to reverse the disease, delay and prevent it from developing.
  • AD support the evidence that activated immune and inflammatory processes is a part of the disease. Also a strong benefit of long-term use of NS A TPs was shown in epidemiological studies. So it is generally accepted that AD is partially an inflammatory disease and that inhibiting inflammation is an option of treating AD. [007] Inflammation clearly occurs in pathologically vulnerable regions of the AD brain, and it does so with the full complexity of local peripheral inflammatory responses. In the periphery, degenerating tissue and the deposition of highly insoluble abnormal materials are classical stimulants of inflammation. Likewise, in the AD brain damaged neurons and neurites and highly insoluble amyloid b peptide deposits and neurofibrillary tangles provide obvious stimuli for inflammation.
  • Azelastine is classified pharmacologically as a second generation antihistamine and is a relatively selective, non- sedating, competitive antagonist at HI receptors. More uniquely, its inhibition of inflammatory mediators, in addition to antihistaminic and mast cell stabilizing effects, places it among the new generation of dual-acting anti-inflammatory drugs. In addition to azelastine’ s high affinity for HI receptors, its ability to modify several other mediators of inflammation and allergy contributes to its mechanism of action. In vitro and in vivo studies, as well as clinical trials support the dual effects of direct inhibition and stabilization of inflammatory cells.
  • azelastine s affinity for HI receptors is estimated to be several times greater than that of chlorpheniramine, a first- generation HI antagonist.
  • Azelastine has only weak affinity for H2 receptors. Release of histamine from mast cells is also inhibited possibly by reversible inhibition of voltage-dependent L-type calcium channels. Inhibition of mast cell degranulation may also decrease the release of other inflammatory mediators, including leukotrienes and interleukin- 1b, among others.
  • Azelastine also directly antagonizes other mediators of inflammation, such as tumor necrosis factor-a, leukotrienes, endothelin-1, and platelet- activating factor.
  • the present invention includes the discovery of a method of administering azelastine or a pharmaceutically acceptable salt of azelastine to patients for treating mental, behavioral, cognitive disorders.
  • the pharmaceutically acceptable salt of azelastine is azelastine hydrochloride.
  • azelastine hydrochloride is provided in a daily effective amount of about 4 mg to about 40 mg.
  • the present invention also includes an oral pharmaceutical dosage form of the pharmaceutically acceptable salt form of azelastine that is a solid form or a liquid form.
