Definitions

• the present invention relates to compositions and methods for dosing psychedelics.
• Psychedelics including lysergic acid diethylamide are substances capable of inducing unique subjective effects including alterations of consciousness, positive emotions, enhanced introspection, changes in the perception of the environment, the body, and the self as well as synesthesia, mystical-type experiences, and experiences of ego dissolution (Carhart-Harris et al., 2016b; Dolder et al., 2016; Holze et al., 2021 ; Liechti, 2017; Passie et al., 2008; Schmid et al., 2015).
• All serotonergic psychedelics including LSD, psilocybin, DMT, and mescaline are nonspecific serotonin agonists including agonist activity at the serotonin 5-HT2A receptor (Rickli et al., 2016) and may therefore produce overall largely similar effects. Additionally, psychedelic substances produce their acute effects in humans via activation of the serotonin 5- HT2A receptor as specifically shown in clinical studies for LSD (Holze et al., 2021 ; Preller et al., 2017). LSD and other hallucinogens are partial agonists of the serotonin 5-HT2A receptor (Lopez-Gimenez, et al.
• Acute effects of psychedelics that may contribute to their therapeutic benefits include enhancing the therapeutic relationship by increased openness, trust, feelings of connectedness or emulsion with people, insight in psychological problems and stimulation of neuroregenerative processes as described in detail elsewhere (Vollenweider & Preller, 2020).
• Psychedelic administration especially at doses believed to be therapeutic, has a side effect of hallucinations or perceptual disturbances (Ungerleider, J. THOMAS. "The acute side effects from LSD.” The problems and prospects of LSD (1968): 61 -68), (Nichols, Psychedelics, Pharmacol Rev 68:264-355).
• titration is a method that limits potential side effects by taking time to see how one’s body reacts to a drug, wherein medication is started at a low dose and then the dose is raised every couple of weeks until the maximum effective dose (target dose) has been achieved or side effects occur.
• Caffrey, et al. (Ther Adv Drug Saf. 2021 Jan 19; 11 : 2042098620958910) describes that titration is commonly used for drugs with a narrow therapeutic index to provide treatment at the lowest dose possible while minimizing medication use and side effects. It is a patient-centered approach to provide individualized therapy. Titration has been used for antibiotics, anticoagulants, anticonvulsants, antidepressants, antidiabetics, antipsychotics, opioids, and stimulants.
• the present invention provides for a method of dosing a psychedelic that avoids the side effects of hallucinations and perceptual disturbances by administering the psychedelic to an individual in a titrating dosing regimen and reducing side effects of hallucinations and perceptual disturbances.
• the present invention provides for a kit for administering a titrating dosing regimen of a psychedelic, including a pharmaceutically effective amount of the psychedelic in dosage forms separated in packaging according to dose and time of administration in a titrating dosing regimen, and instructions for use.
• the present invention also provides for a method of treating an individual with psychedelics, by administering the psychedelic to the individual having a condition or disease in a titrating dosing regimen and reducing side effects of hallucinations and perceptual disturbances during treatment.
• FIGURE 1 is a graph of dose versus time.
• the present invention provides for a method of dosing a psychedelic that avoids the side effects of hallucinations and perceptual disturbances by administering the psychedelic to an individual in a titrating dosing regimen and reducing side effects of hallucinations, perceptual disturbances, and other immediately detectable effects of the psychedelic while preserving desired therapeutic benefits.
• the titrating dosing regimen can include administering a starting dose to the individual, and at a set amount of time, increasing the dose a set amount and administering the increased dose to the individual, and repeating these steps over a period of time that the individual is being treated and until a maximum desired dose is reached.
• the starting dose can be a sub-perceptual dose (e.g., 10 pg) and taper up over time in a regimen that would never have the hallucinatory side effect but would achieve an effective dose that would be perceptual/hallucinogenic if administered in the absence of the titration regimen (e.g., 30, 50, 100 or 200 pg as the target therapeutic dose).
• the starting dose can be 10 pg, which is increased by 10 pg every (2, 3, 4, 5, 6 or 7 days).
• Other starting doses can be within the ranges described below. Other examples of dosing can be found in Buchborn (2016).
• the time period can be hours, days, weeks, months, or years, or intervals of dose titration with intervals of non-dosing, where each dose titration period can lead to the ability to avoid hallucinations, perceptual, and other detectable effects of the psychedelic, while preserving or enhancing desired therapeutic effects.
• the starting dose and increased dose levels can be administered once per day, twice per day or three times per day, and can be administered by a care giver, healthcare provider, or self administered by the patient with or without supervision.
• the dose increase can be any small amount such as 10, 20, 30 or 50 pg, and can be effected and determined by drug and formulation variation, and patient specific factors such as weight, height, body surface area, biochemical assays, metabolic assays, or genomic assays.
• the dosage form used can be any suitable dosage form such as tablets, capsules, lozenges, transdermal patches, implanted devices, solutions, gels, emulsions, or any solid or liquid form, or some combination of forms, as well as those further described below.
• the starting dose can also be a larger loading dose administered under medical supervision followed by repeat sub-perceptual doses to maintain the treatment benefit while limiting side effects to only the first dose.
• the psychedelics in the present invention can be, but are not limited to, lysergic acid diethylamide (LSD), psilocybin, mescaline, 5-methoxy-N,N-dimethyltryptamine (5-MeO- DMT), dimethyltryptamine (DMT), 2,5-dimethoxy-4-iodoamphetamine (DOI), 2,5-dimethoxy-4- bromoamphetamie (DOB), salts thereof, tartrates thereof, analogs thereof, or homologues thereof.
• the dose of the psychedelic is one that provides a meaningful effect.
• a dose of 0.01-1 mg (10-1000 pg) can be used of LSD.
• Psilocybin can be dosed at 5-50 mg
• mescaline can be dosed at 50-800 mg
• 5-MeO-DMT can be dosed at 1 -20 mg
• DMT can be dosed at 20-100 mg
• DOI can be dosed at 0.1-5 mg
• DOB can be dosed at 0.1-5 mg.
• Effects of the psychedelic drug can last 1 -12 hours after administration, and the individual can be supervised by medical personnel such as a psychiatrist during this time. If lower doses are given, medical supervision can be unnecessary.
• the present invention can carry out its clinical effect by down-regulating (or reducing the expression of) the serotonin 5-HT2A receptor or by another mechanism of action that reduces the hallucinogenic effects of a psychedelic drug over time.
• the compounds of the present invention are administered and dosed in accordance with good medical practice, considering the clinical condition of the individual patient, the site and method of administration, scheduling of administration, patient age, sex, body weight and other factors known to medical practitioners.
• the pharmaceutically "effective amount" for purposes herein is thus determined by such considerations as are known in the art. The amount must be effective to achieve improvement including but not limited to improved survival rate or more rapid recovery, or improvement or elimination of symptoms and other indicators as are selected as appropriate measures by those skilled in the art.
• the compounds of the present invention can be administered in various ways. It should be noted that they can be administered as the compound and can be administered alone or as an active ingredient in combination with pharmaceutically acceptable carriers, diluents, adjuvants, and vehicles.
• the compounds can be administered orally, transcutaneously, subcutaneously or parenterally including intravenous, intramuscular, and intranasal administration.
• the patient being treated is a warm blooded animal and, in particular, mammals including man.
• the pharmaceutically acceptable carriers, diluents, adjuvants, and vehicles as well as implant carriers generally refer to inert, non-toxic solid or liquid fillers, diluents or encapsulating material not reacting with the active ingredients of the invention.
• the doses can be single doses or multiple doses or a continuous dose over a period of several hours, days, weeks, or months.
• the compound of the present invention When administering the compound of the present invention parenterally, it will generally be formulated in a sublingual or buccal dissolving tablet, dissolving film, intranasal powder, intranasal solution, inhaled powder, inhaled solution, transdermal patch, transdermal patch (with microneedles or other permeation enhancers) or as a unit dosage injectable form (solution, suspension, emulsion).

• the carrier can be a solvent or dispersing medium containing, for example, water, ethanol, polyol (for example, glycerol, propylene glycol, liquid polyethylene glycol, and the like), suitable mixtures thereof, and vegetable oils.
• Proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants.
• Nonaqueous vehicles such as cottonseed oil, sesame oil, olive oil, soybean oil, corn oil, sunflower oil, or peanut oil and esters, such as isopropyl myristate, may also be used as solvent systems for compound compositions.
• various additives which enhance the stability, sterility, and isotonicity of the compositions including antimicrobial preservatives, antioxidants, chelating agents, and buffers, can be added.
• antibacterial and antifungal agents for example, parabens, chlorobutanol, phenol, sorbic acid, and the like.
• isotonic agents for example, sugars, sodium chloride, and the like.
• Prolonged absorption of the injectable pharmaceutical form can be brought about by the use of agents delaying absorption, for example, aluminum monostearate and gelatin.

• TABLE 1 shows oral administration over different days and for different times of daily administration.
• the dose levels can translate into 1) a PK threshold and 2) a 5-HT2A expression threshold that can be tailored via other dosing regiments and formulations so that the dosing is done in a way that patients never get PK levels that match the (increasing) threshold for perceptual effects.
• FIGURE 1 shows how the dose increases over time to a threshold for perceptual effects. Similar effects would be present for PK levels.
• TABLE 2 shows dosing with an extended release formulation.
• Precise packaging configurations can be used, such as a dosing kit of multiple patches that can be applied at regular intervals either at home or in a clinic.
• the kit design i.e., specific way the patches are sized, any differences in their properties, and the actual packaging design
• the kit design can ensure adherence and so that patients do not inadvertently expose themselves to a hallucinogenic dose.
