Ayahuasca: Spiritual Pharmacology & Drug Interactions
Ayahuasca: Spiritual Pharmacology & Drug Interactions BENJAMIN MALCOLM, PHARMD, MPH [email protected] MARCH 28 TH 2017 AWARE PROJECT Can Science be Spiritual? “Science is not only compatible with spirituality; it is a profound source of spirituality. When we recognize our place in an immensity of light years and in the passage of ages, when we grasp the intricacy, beauty and subtlety of life, then that soaring feeling, that sense of elation and humility combined, is surely spiritual. The notion that science and spirituality are somehow mutually exclusive does a disservice to both.” – Carl Sagan Disclosures & Disclaimers No conflicts of interest to disclose – I don’t get paid by pharma and have no potential to profit directly from ayahuasca This presentation is for information purposes only, none of the information presented should be used in replacement of medical advice or be considered medical advice This presentation is not an endorsement of illicit activity Presentation Outline & Objectives Describe what is known regarding ayahuasca’s pharmacology Outline adverse food and drug combinations with ayahuasca as well as strategies for risk management Provide an overview of spiritual pharmacology and current clinical data supporting potential of ayahuasca for treatment of mental illness Pharmacology Terms Drug ◦ Term used synonymously with substance or medicine in this presentation and in pharmacology ◦ No offense intended if I call your medicine or madre a drug!

The Migraine Attack As a Homeostatic, Neuroprotective Response to Brain Oxidative Stress: Preliminary Evidence for a Theory
ISSN 0017-8748 Headache doi: 10.1111/head.13214 VC 2017 American Headache Society Published by Wiley Periodicals, Inc. Views and Perspectives The Migraine Attack as a Homeostatic, Neuroprotective Response to Brain Oxidative Stress: Preliminary Evidence for a Theory Jonathan M. Borkum, PhD Background.—Previous research has suggested that migraineurs show higher levels of oxidative stress (lipid peroxides) between migraine attacks and that migraine triggers may further increase brain oxidative stress. Oxidative stress is trans- duced into a neural signal by the TRPA1 ion channel on meningeal pain receptors, eliciting neurogenic inflammation, a key event in migraine. Thus, migraines may be a response to brain oxidative stress. Results.—In this article, a number of migraine components are considered: cortical spreading depression, platelet acti- vation, plasma protein extravasation, endothelial nitric oxide synthesis, and the release of serotonin, substance P, calcitonin gene-related peptide, and brain-derived neurotrophic factor. Evidence is presented from in vitro research and animal and human studies of ischemia suggesting that each component has neuroprotective functions, decreasing oxidant production, upregulating antioxidant enzymes, stimulating neurogenesis, preventing apoptosis, facilitating mitochondrial biogenesis, and/or releasing growth factors in the brain. Feedback loops between these components are described. Limitations and challenges to the model are discussed. Conclusions.—The theory is presented that migraines are an integrated -
What Are the Acute Treatments for Migraine and How Are They Used?
2. Acute Treatment CQ II-2-1 What are the acute treatments for migraine and how are they used? Recommendation The mainstay of acute treatment for migraine is pharmacotherapy. The drugs used include (1) acetaminophen, (2) non-steroidal anti-inflammatory drugs (NSAIDs), (3) ergotamines, (4) triptans and (5) antiemetics. Stratified treatment according to the severity of migraine is recommended: use NSAIDs such as aspirin and naproxen for mild to moderate headache, and use triptans for moderate to severe headache, or even mild to moderate headache when NSAIDs were ineffective in the past. It is necessary to give guidance and cautions to patients having acute attacks, and explain the methods of using medications (timing, dose, frequency of use) and medication use during pregnancy and breast-feeding. Grade A Background and Objective The objective of acute treatment is to resolve the migraine attack completely and rapidly and restore the patient’s normal functions. An ideal treatment should have the following characteristics: (1) resolves pain and associated symptoms rapidly; (2) is consistently effective; (3) no recurrence; (4) no need for additional use of medication; (5) no adverse effects; (6) can be administered by the patients themselves; and (7) low cost. Literature was searched to identify acute treatments that satisfy the above conditions. Comments and Evidence The acute treatment drugs for migraine generally include (1) acetaminophens, (2) non-steroidal anti-inflammatory drugs (NSAIDs), (3) ergotamines, (4) triptans, and (5) antiemetics. For severe migraines including status migrainosus and migraine attacks refractory to treatment, (6) anesthetics, and (7) corticosteroids (dexamethasone) are used (Tables 1 and 2).1)-9) There are two approaches to the selection and sequencing of these medications: “step care” and “stratified care”. -
PMA-Sio2: Heteropolyacid Catalysis for Michael Addition-Convenient Route to Substituted-3-Indoles

The catalyst is recyclable for three to four times without great loss in the activity. Keywords: Phosphomolybdic Acid (PMA), Substituted indoles, α, β-unsaturated carbonyl compounds, α, β-unsaturated nitro compounds, Michael addition INTRODUCTION Heterocyclic chemistry is one of the quintessential branches of organic synthesis beaconing towards new scaffolds with medicinal values, new methodologies to the existing active principles etc. One among such skeletons is indole. It is perhaps the most common heterocycles in chemistry and its derivatives are obtained from coal pitch, variety of plants or by the bacterial decay of tryptophan in the intestine [1]. Indole derivatives serve as signaling chemicals in plants and animals, as nucleus building blocks (serotonin [2] (A) a crucial neurotransmitter in the central nervous system [3]), as antibacterial [4], antiviral [5], protein kinase inhibitors [6], anticancer agents [7], entheogens (psilocybin (B) causes perceptional changes), hormones (melatonin (C) regulates sleep and wakefulness), antidepressants (roxindole (D), bufotenin (E)), sumatriptan (F) for the treatment of migraine and ondansetron (G) for the suppression of nausea and vastly found in natural products such as alkaloids (Corynanthe, Iboga, and Aspidosperma alkaloids) [8-10], indigoids etc., which originate, either fully or partly, from bio-oxidation of indoles [11]. -

Pharmacokinetics, Pharmacodynamics and Drug
pharmaceutics Review Pharmacokinetics, Pharmacodynamics and Drug–Drug Interactions of New Anti-Migraine Drugs—Lasmiditan, Gepants, and Calcitonin-Gene-Related Peptide (CGRP) Receptor Monoclonal Antibodies Danuta Szkutnik-Fiedler Department of Clinical Pharmacy and Biopharmacy, Pozna´nUniversity of Medical Sciences, Sw.´ Marii Magdaleny 14 St., 61-861 Pozna´n,Poland; [email protected] Received: 28 October 2020; Accepted: 30 November 2020; Published: 3 December 2020 Abstract: In the last few years, there have been significant advances in migraine management and prevention. Lasmiditan, ubrogepant, rimegepant and monoclonal antibodies (erenumab, fremanezumab, galcanezumab, and eptinezumab) are new drugs that were launched on the US pharmaceutical market; some of them also in Europe. This publication reviews the available worldwide references on the safety of these anti-migraine drugs with a focus on the possible drug–drug (DDI) or drug–food interactions. As is known, bioavailability of a drug and, hence, its pharmacological efficacy depend on its pharmacokinetics and pharmacodynamics, which may be altered by drug interactions. This paper discusses the interactions of gepants and lasmiditan with, i.a., serotonergic drugs, CYP3A4 inhibitors, and inducers or breast cancer resistant protein (BCRP) and P-glycoprotein (P-gp) inhibitors. In the case of monoclonal antibodies, the issue of pharmacodynamic interactions related to the modulation of the immune system functions was addressed. It also focuses on the effect of monoclonal antibodies on expression of class Fc gamma receptors (FcγR). Keywords: migraine; lasmiditan; gepants; monoclonal antibodies; drug–drug interactions 1. Introduction Migraine is a chronic neurological disorder characterized by a repetitive, usually unilateral, pulsating headache with attacks typically lasting from 4 to 72 h. -

Summary of Product Characteristics
SUMMARY OF PRODUCT CHARACTERISTICS 1. NAME OF THE MEDICINAL PRODUCT [Invented name] 12.5 mg film-coated tablets 2. QUALITATIVE AND QUANTITATIVE COMPOSITION Each tablet contains almotriptan 12.5 mg (as almotriptan malate 17.5 mg). For a full list of excipients, see section 6.1. 3. PHARMACEUTICAL FORM Film-coated tablet. Description: white to off-white, round, biconvex film-coated tablets, diameter of tablets max.6.2 mm. 4. CLINICAL PARTICULARS 4.1 Therapeutic indications Acute treatment of the headache phase of migraine attacks with or without aura. 4.2 Posology and method of administration Almotriptan should be taken with liquids as early as possible after the onset of migraine- associated headache but it is also effective when taken at a later stage. Almotriptan should not be used for migraine prophylaxis. The tablets can be taken with or without food. Adults (18-65 years of age) The recommended dose is one tablet containing 12.5 mg of almotriptan. A second dose may be taken if the symptoms reappear within 24 hours. This second dose may be taken provided that there is a minimum interval of two hours between the two doses. The efficacy of a second dose for the treatment of the same attack when an initial dose is ineffective has not been examined in controlled trials. Therefore if a patient does not respond to the first dose, a second dose should not be taken for the same attack. The maximum recommended dose is two doses in 24 hours. Children and adolescents (under 18 years of age) There are no data concerning the use of almotriptan in children and adolescents, therefore its use in this age group is not recommended. -

Received: 21 September 2020; Accepted: 20 October 2020; Published: 23 October 2020 Abstract: Ayahuasca is a hallucinogenic botanical beverage originally used by indigenous Amazonian tribes in religious ceremonies and therapeutic practices. While ethnobotanical surveys still indicate its spiritual and medicinal uses, consumption of ayahuasca has been progressively related with a recreational purpose, particularly in Western societies. The ayahuasca aqueous concoction is typically prepared from the leaves of the N,N-dimethyltryptamine (DMT)-containing Psychotria viridis, and the stem and bark of Banisteriopsis caapi, the plant source of harmala alkaloids.
