Definitions
- the invention relates to the field of practical medicine, namely, to the combined use of pharmaceutical compositions exhibiting a neurotropic action, alleviating manifestations of mental, behavioral, 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.
- AD is a polygenic/multifactorial complex disorder characterized by the premature death of neurons.
- amyloid hypothesis is recognized as the Primum Movens of AD pathogenesis, mutational genetics associated with amyloid precursor protein (APP) and presenilin (PS) genes lone does not explain in full the neuropathologic findings present in AD, represented by amyloid deposition in senile plaques and vessels (amyloid angiopathy), neurofibrillary tangle (NFT) formation due to hyperphosphorylation of tau protein, synaptic and dendritic desarborization and neuronal loss.
- APP amyloid precursor protein
- PS presenilin
- AD-related memory dysfunction was in part due to a cholinergic deficit in the brain of affected people due to a loss of neurons in the basal forebrain, this giving rise to the cholinergic hypothesis of AD.
- AChEIs were proposed as an option to inhibit acetylcholine degradation in the synaptic cleft and to increase choline reuptake at the presynaptic level with the aim of enhancing acetylcholine synthesis in presynaptic terminals, this facilitating cholinergic neurotransmission.
- tacrine tetrahydroaminoacridine
- donepezil was approved by the FDA for the treatment of mild-to- moderate cases of AD.
- AChEIs, rivastigmine and galantamine were introduced several years later.
- acetylcholinesterase inhibitors such as donepezil, rivastigmine and galantamine 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 Alzheimer's disease
- Inflammation clearly occurs in pathologically vulnerable regions of the AD brain, and it does so with the full complexity of local peripheral inflammatory responses.
- degenerating tissue and the deposition of highly insoluble abnormal materials are classical stimulants of inflammation.
- damaged neurons and neurites and highly insoluble amyloid b peptide deposits and neurofibrillary tangles provide obvious stimuli for inflammation. Because these stimuli are discrete, micro-localized, and present from early preclinical to terminal stages of AD, local upregulation of complement, cytokines, acute phase reactants, and other inflammatory mediators is also discrete, micro-localized, and chronic.
- Azelastine is classified pharmacologically as a second generation antihistamine and is a relatively selective, nonsedating, 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. 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. In vitro data indicate that azelastine’ s affinity for 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. Therefore, a unique combination of azelastine and donepezil and/or rivastigmine and/or galantamine is expected to be, in terms of creating synergistic effects, innovative potential treatments for AD.

It is understood that reduced or delayed, as used in this context, means relative to the state of the untreated disease, including the molecular state of the untreated disease, not just the physiological state of the untreated disease.
- the pharmaceutical composition may be formulated for pharmaceutical use using methods known in the art, for example, Ansel's Pharmaceutical Dosage Forms and Drug Delivery Systems Tenth (by Loyd Allen, 2013) and Handbook of Pharmaceutical Manufacturing Formulations (Volumes 1-6 by Sarfaraz K. Niazi). Accordingly, incorporation of the active compounds and a controlled, or slow release matrix may be implemented.
