[0008] In some embodiments, the present invention relates to a method for treating an acute myocardial infarction in a subject in need, the method comprising administering a sublingual aspirin cocrystal with citric acid, sodium bicarbonate, and L-theanine to the subject. In one embodiment, the sublingual aspirin, citric acid, sodium bicarbonate, and L-theanine cocrystal are directly absorbed in the bloodstream of the subject, bypassing the first-pass effect of the liver. Detailed Implementation Early administration of novel sublingual aspirin, citrate, sodium bicarbonate, and L-theanine cocrystal formulations for the treatment of acute myocardial infarction is crucial, and patients can begin to benefit within minutes, whereas the full benefits of conventional aspirin may not materialize until major sequelae (such as ventricular tachycardia, ventricular fibrillation, complete heart block, or death) occur. Therefore, there is a significant unmet need in patients with acute myocardial infarction for novel sublingual aspirin, citrate, sodium bicarbonate, and L-theanine cocrystal formulations with improved pharmacokinetics and pharmacodynamics. This invention addresses these and other medical needs and overcomes the deficiencies of the prior art.

[0009] Compared to the conventional oral route of aspirin, the advantages of the sublingual cocrystal of aspirin, citrate, sodium bicarbonate, and L-theanine include increased dissolution rate and bioavailability when rapid onset of action is required. The sublingual vascular network provides increased drug absorption compared to the oral route. Therefore, the sublingual vascular network results in a faster dissolution rate, especially if the saliva pH is greater than 6. The sublingual route bypasses the hepatic first-pass effect, leading to increased drug bioavailability because the drug is absorbed directly into the systemic circulation rather than through the gastrointestinal tract, where it is first delivered to the liver via the portal vein and then metabolized in the liver before entering the systemic circulation. Patients with a history of acute coronary syndrome can self-administer this cocrystal of aspirin, citrate, sodium bicarbonate, and L-theanine at home or at work before an ambulance arrives, while in the field, or during an acute episode of chest pain while traveling by air. Patients with a history of dysphagia (difficulty swallowing) or dysphagia (pain when swallowing) will benefit from the sublingual route.

[0010] A significant drawback of the sublingual route occurs in patients who smoke. Smokers will not fully benefit from the sublingual route because smoking causes vasoconstriction, which reduces drug absorption.

[0011] The ongoing interest in improving the physical properties of pharmaceutical substances has led to significant research into issues related to polymorphism and solvation morphology. Recently, it has been recognized that many substances can co-crystallize in a single continuous lattice structure, thus opening new avenues for pharmaceutical scientists to crystal engineering.

[0012] A eutectic is a mixed crystal, in which a eutectic is a homogeneous crystalline material formed from discrete, neutral molecules that are solid at ambient temperatures. A characteristic of a eutectic is that two or more molecules are associated at the molecular level but not bonded.

[0013] Cocrystals represent a new form of pharmaceutical substance that will be suitable for incorporation into solid dosage forms and should enable formulation scientists to overcome various problems encountered during the development of conventional formulations. Cocrystals can be considered as alternatives to polymorphs, solvatomorphs, and salts because they represent different approaches to addressing issues such as those related to dissolution, crystallinity, and hygroscopicity.

[0014] Eutectic crystals are attractive to the pharmaceutical industry because they offer the opportunity to alter the chemical and / or physical properties of APIs without the need to form or break covalent bonds.

[0015] Unfortunately, it is not yet possible to predict whether two substances will co-crystallize, and therefore co-crystallization screening studies are essentially empirical.

[0016] Given the structural similarity between glutamine and glutamic acid and theanine, and the fact that neither glutamine nor glutamic acid forms co-crystals with aspirin, one might have been led to infer that theanine would also not form co-crystals with aspirin. Despite this expectation, aspirin does indeed form co-crystals with theanine, but it does not form co-crystals with either glutamine or glutamic acid.

[0017] The conformational isomers described below are highly structurally related to L-theanine: Eutectic engineering can be used to improve one or more physical properties of a selected therapeutic or preventative active pharmaceutical ingredient, such as solubility, stability, and dissolution rate.

[0018] Salicylic acid is the active metabolite of aspirin.

[0019] Therapeutic compounds, such as aspirin, are most stable in their crystalline form, but may exhibit poor water solubility and a slow dissolution rate. These properties tend to reduce the bioavailability of the active pharmaceutical ingredient (API), thereby slowing absorption.

[0020] Myocardial infarction is most often caused by the rupture of atherosclerotic lesions in the coronary arteries. This rupture leads to the formation of a coronary thrombus or blood clot, which blocks the artery and prevents the artery from supplying blood and oxygen to the heart muscle, which is normally supplied by that vessel. As a result, ischemic death of myocardial cells occurs.

[0021] Activated macrophages and T lymphocytes at the plaque rupture site release metalloproteinases and cytokines, which weaken the fibrotic cap, making it susceptible to erosion or tearing due to shear stress exerted by blood flow. Plaque rupture exposes subendothelial collagen, a site of platelet adhesion, activation, and aggregation. This leads to the release of substances such as thromboxane A2, fibrinogen, serotonin, platelet-activating factor, and ADP (adenosine diphosphate), which further promotes platelet aggregation. Activation of the coagulation cascade leads to fibrin formation and the propagation of obstructive thrombi. When a thrombus forms on the ruptured plaque, it eventually obstructs the artery. Rupture of atherosclerotic plaques with superimposed thrombi accounts for 95% of acute myocardial infarction cases.

[0022] Inflammation and inflammatory cell infiltration are hallmarks of myocardial infarction and reperfusion injury. Ischemic cardiac injury activates the innate immune response via Toll-like receptors and upregulates the expression of chemokines and cytokines in the infarcted heart. The continuous infiltration of damaged myocardium by neutrophils, monocytes and their progeny macrophages, dendritic cells, and lymphocytes contributes to the initiation and resolution of inflammation, infarction healing, angiogenesis, and ventricular remodeling. The detrimental and beneficial effects in the pathophysiology of myocardial infarction (MI) and reperfusion injury may be attributed to the heterogeneity and functional diversity of these inflammatory cell subsets.

[0023] Aspirin irreversibly inhibits platelet cyclooxygenase 1 (COX-1) by acetylation of serine at amino acid position 529, thereby preventing arachidonic acid from entering the COX-1 catalytic site through steric hindrance. By inhibiting COX-1, platelets cannot synthesize prostaglandin H2, which is otherwise converted to thromboxane A2. Thromboxane A2 induces platelet aggregation, an early step in the coagulation cascade.

[0024] Theanine is found in green tea leaves (Camellia sinensis) and the non-edible mushroom *Xerocomus badius*, but is otherwise rare in nature. Tea is the second most consumed beverage in the world. Monks have been drinking tea containing theanine for over 4,000 years. L-Theanine is an ingredient in fruit juices and beverages, non-herbal teas, sports drinks, bottled water, chocolate bars, hard candies, mints, and chewing gum. Theanine is extremely safe, with an LD50 toxicity of >5000 mg / kg in rats. Based on the FDA's GRAS assessment of L-theanine (which is based on a statistical analysis of potential dietary intake), the estimated average theanine consumption is 682 mg / person / day, and the 90th percentile consumption is 1284 mg (1.28 g) / person / day.

[0025] L-Theanine (N-ethyl-L-glutamine) is an amino acid analog of glutamine and is a water-soluble non-protein amino acid. It is a tasteless, white crystalline powder, soluble in water, and transparent in solution. L-Theanine has Chemical Abstracts Service (CAS) registration number 3081-61-6 and GRAS classification (GRAS notification number: GRN000209). L-Theanine has the empirical formula C7H 14 N₂O₃ has a molecular weight of 174.20, a pKa of 2.35, and a melting point of 217-218℃. In the kidneys, glutaminase hydrolyzes theanine into glutamate and ethylamine.

[0026] Chemical structure of L-theanine Theanine is known to have several mechanisms of action. Thrombin is a serine protease that converts fibrinogen into fibrin during the coagulation cascade that leads to clot formation. Theanine itself is a potent inhibitor of thrombin-stimulated thromboxane preparations in whole blood. Therefore, theanine has an anticoagulant effect. This anticoagulant effect of theanine can be beneficial in the treatment of acute myocardial infarction when administered sublingually as a cocrystal of aspirin with citrate, sodium bicarbonate, and L-theanine. Theanine promotes the generation of alpha waves in the brain, inducing a relaxed mental and physical state without causing drowsiness. This relaxed mental and physical state would be beneficial in patients with acute myocardial infarction.

[0027] Theanine enhances the solubility of aspirin in water. As a 5-N-ethylglutamine, theanine differs from glutamine in that the CH2-CH3 (ethyl) group replaces the hydrogen. The N-ethyl group imparts its active properties to theanine. Theanine and its analogues form zwitterions at neutral pH. The ionic charge can be used to pair with the ortho-carboxylic acid anion of acetylsalicylic acid via cation or protonated α-amino groups. This can be further stabilized by hydrogen bonding with the nitrogen of the ethylcarboxamide (the acetylammonium is a functional marker of theanine-type molecules). Crystals of this ion pair can encapsulate more water molecules than either molecule alone. This makes the complex readily solubilized when dissolved in water or buffer solutions.

[0028] Aspirin protects against several types of toxicity, including excitotoxicity (glutamate), dopamine toxicity, and oxidative free radical toxicity.

[0029] Excitotoxicity is a pathological process responsible for neuronal cell death caused by excessive stimulation of neurotransmitters (such as glutamate). Pathologically, high levels of glutamate can cause neuronal cell death by allowing high levels of calcium ions (Ca). 2+ This calcium (Ca) enters cells and causes excitotoxicity. 2+The influx of theanine into cells leads to the release of multiple enzymes, resulting in neuronal death. It has been shown that theanine is related to AMPA (…). It binds to α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid, phycocyanin, NMDA (N-methyl-D-aspartate), and group 1mGluR receptors, thereby antagonizing excitatory neurotransmitters.

[0030] GABA (gamma-aminobutyric acid) is the most widespread inhibitory neurotransmitter in the brain. When GABA levels decrease, nerve impulses increase in neurons. Theanine increases GABA levels in the brain, counteracting the overstimulation of nerve impulses by excitatory neurotransmitters (such as glutamate), which can be found in patients with stroke and traumatic brain injury.

[0031] L-Theanine crosses the blood-brain barrier via a large, neutral amino acid-preferred transport system of leucine and has been shown to produce significant increases in serotonin and / or dopamine concentrations in the brain, primarily in the striatum, hypothalamus, and hippocampus. The ability of L-theanine to increase serotonin and dopamine concentrations in the brain will be beneficial in treating migraine patients where serotonin and dopamine levels are typically low.

[0032] A novel sublingual water-soluble cocrystal of aspirin, citric acid, sodium bicarbonate, and L-theanine, which crosses the blood-brain barrier, will have neuroprotective effects on a variety of central nervous system disorders associated with glutamate excitotoxicity, such as spinal cord injury, stroke, traumatic brain injury, multiple sclerosis, Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis.

[0033] Researchers at the Boyce Thompson Institute and Johns Hopkins University have discovered that salicylic acid, the active metabolite of aspirin, binds to glyceraldehyde-3-phosphate dehydrogenase (GAPDH), preventing the enzyme from entering the neuronal nucleus, where it enhances protein turnover and leads to cell death. GAPDH is believed to play a crucial role in neurodegenerative diseases, including Alzheimer's, Parkinson's, and Huntington's diseases. A novel sublingual water-soluble cocrystal of aspirin, along with citrate, sodium bicarbonate, and L-theanine, will be essential in preventing neuronal cell death by binding salicylic acid to glyceraldehyde-3-phosphate dehydrogenase.

[0034] Theanine inhibits the efflux of chemotherapeutic agents (such as doxorubicin, idarubicin, cisplatin, and irinotecan), leading to elevated drug levels in cancer cells, which strongly suppresses tumor growth. Theanine blocks the export of doxorubicin, idarubicin, cisplatin, and irinotecan from cancer cells by blocking the glutamate and glutathione transport mechanisms. Cancer cells use glutathione to counteract the toxicity of doxorubicin, idarubicin, cisplatin, and irinotecan and to deliver the drugs out of the cell. Theanine is able to interfere with this process due to its structural similarity to glutamate.

[0035] The various novel features characterizing the invention are specifically pointed out in the claims appended to and forming a part of this disclosure. For a better understanding of the invention, its operation, advantages, and specific objectives obtained through its use, reference is made to the descriptive content in which preferred embodiments of the invention are shown.

[0036] Therefore, one object of the present invention is to provide a method for using a cocrystal composition of aspirin with citric acid, sodium bicarbonate and L-theanine, said composition being readily administered to humans via the sublingual route, bypassing the first-pass effect of the liver, and improving dissolution rate and bioavailability.

[0037] Another object of the present invention is to provide a water-soluble aspirin, citric acid, sodium bicarbonate and theanine eutectic composition having the above-mentioned characteristics, and which is rapidly soluble in water.

[0038] Another object of the present invention is to provide a water-soluble cocrystal formulation of aspirin, citric acid, sodium bicarbonate, and theanine suitable for sublingual administration, having the above-mentioned characteristics and allowing acetylsalicylic acid to be rapidly delivered into the bloodstream.

[0039] Another object of the present invention is to provide a water-soluble cocrystal formulation of aspirin, citric acid, sodium bicarbonate, and theanine suitable for sublingual administration, having the above-mentioned characteristics and allowing for the rapid delivery of a therapeutic amount of theanine into the bloodstream.

[0040] A further object of the present invention is to provide a method for sublingual administration of a cocrystal composition of water-soluble aspirin, citric acid, sodium bicarbonate, and theanine in humans, said composition providing enhanced dissolution and bioavailability and being suitable for the treatment of acute myocardial infarction.

[0041] A further object of the present invention is to provide a water-soluble cocrystal composition of aspirin, citric acid, sodium bicarbonate, and theanine suitable for sublingual administration, which has the above-mentioned characteristics and is expected to reduce median platelet aggregation inhibition time compared with conventional oral aspirin.

[0042] A further object of the present invention is to provide a water-soluble cocrystal formulation of aspirin, citric acid, sodium bicarbonate, and theanine suitable for sublingual administration, having the above-mentioned characteristics and bypassing the gastrointestinal tract without causing gastrointestinal irritation, erosion, or bleeding that may occur with conventional oral aspirin use.

[0043] Embodiments of the present invention may include enantiomers, L- and D-isomers, D,L-racemic mixtures, S- and R-isomers, S,R-racemic mixtures, all rotational isomers, tautomers, salt forms, and hydrate cocrystal compositions of drugs of the kinds listed below with α and β amino acids of theanine, wherein the N-substituted functional R1-group [C4 or γ-CH2-C(O)—NR1] may contain straight-chain, cyclic, or branched alkyl groups and their derivatives; straight-chain, cyclic, or branched alkenyl groups and their derivatives; and aromatic groups (which may be aryl groups) and their derivatives, constituting all analogous forms of theanine.

[0044] In some embodiments of the invention, the theanine enantiomer further comprises a carbohydrate functional group thereon. In these embodiments, the carbohydrate functional group may have an L-configuration or a D-configuration. In these embodiments, the carbohydrate used may be a monosaccharide, disaccharide, trisaccharide, oligosaccharide, or polysaccharide.

[0045] In some embodiments of the invention, the theanine enantiomer further comprises an amino acid functional group thereon. In some of these embodiments, the amino acid functional group is a dipeptide.

[0046] Sodium bicarbonate is a white crystalline powder, highly soluble in water, with the molecular formula NaHCO3, CAS number 144-55-8, a molecular weight of 84.006 g / mol, and pKa values ​​of 6.4 and 10.3. Without being limited by the specific theory of this invention, sodium bicarbonate (NaHCO3) deprotonates the carboxylic acid of aspirin to produce sodium acetylsalicylate, which is more soluble in water due to the presence of the charged carboxylate group. Aspirin hydrolysis is pH-independent between 5 and 8, meaning that bicarbonate is a specific base catalyst for generating aspirin anions over a range up to saturation. The hydrolysis of aspirin acetate is pH-independent and depends only on the concentration of the aspirin carboxylate anion. At molar equivalents greater than 1.2, the extraction of a proton from the acid of aspirin is ultrafast and complete.

[0047] Citric acid, 2-hydroxypropane-1,2,3-tricarboxylic acid, CAS No. 77-92-9, has the molecular formula C6H8O7 and a molecular weight of 192.12 g / mol. It is readily soluble in water. It is a tribase with pKa values ​​of 5.21, 4.28, and 2.92 (1-3). Under physiological conditions, one of the acid groups is deprotonated, allowing the acid's conjugate base to bind to other molecules. Acidic citric acid dissolves calcium-based coagulants by chelating calcium out of clot complexes in the blood. Therefore, citrates have anticoagulant effects due to their ability to chelate calcium. This anticoagulant effect is beneficial in patients suffering from acute myocardial infarction when administered sublingually in the form of a cocrystal of aspirin, citric acid, sodium bicarbonate, and L-theanine. In formulations, citric acid reacts with sodium bicarbonate to produce a buffer, disintegrant, and favorable compressibility.

[0048] In one embodiment, this disclosure relates to a composition comprising aspirin, citric acid, sodium bicarbonate, and L-theanine.
