Tyler VE et al, Pharmacognosy , 9 th edition, Lea & Febiger, Philadelphia, 1988. KAVA ( Piper methysticum ) - A REVIEW The Kava plant (Piper methysticum) is a robust, well-branching and erect perennial shrub belonging to the pepper family (Piperaceae). The botanical origin remains unknown, although it is likely that early Polynesian explorers brought the plant with them from island to island. Numerous varieties of Kava exist, and today it is widely cultivated in several Pacific Island countries both for local use as well as the rapidly growing demand for pharmaceutical preparations. The dried rhizomes (roots) are normally used. The first description to the western world of the ceremonial use of an intoxicating beverage prepared from Kava was made by Captain James Cook following his Pacific voyage in 1768. The drink, prepared as an infusion in an elaborate manner after first chewing the root, is consumed on formal occasions or meetings of village elders and chiefs, as well as in reconciling with enemies and on a more social basis. It remains an important social custom in many Pacific Island countries today. Most of the islands of the Pacific possessed Kava prior to European contact, particularly those encompassed by Polynesia, Melanesia and Micronesia. After drinking the Kava beverage a pleasantly relaxed and sociable state develops, after which a deep and restful sleep occurs.

These three authors contribute equally to this work. y Received: 29 June 2019; Accepted: 3 September 2019; Published: 4 September 2019 Abstract: Pain currently represents the most common symptom for which medical attention is sought by patients. The available treatments have limited effectiveness and significant side-effects. In addition, most often, the duration of analgesia is short. Today, the handling of pain remains a major challenge. One promising alternative for the discovery of novel potent analgesics is to take inspiration from Mother Nature; in this context, the detailed investigation of the intriguing analgesia implemented in Buruli ulcer, an infectious disease caused by the bacterium Mycobacterium ulcerans and characterized by painless ulcerative lesions, seems particularly promising. More precisely, in this disease, the painless skin ulcers are caused by mycolactone, a polyketide lactone exotoxin. In fact, mycolactone exerts a wide range of effects on the host, besides being responsible for analgesia, as it has been shown notably to modulate the immune response or to provoke apoptosis.

  • Choice of Drugs in the Treatment of Rheumatoid Arthritis
    RHEUMATOLOGY IN GENERAL PRACTICE 7 Those with predominant but never exclusive involvement of the terminal finger joint, usually associated with changes in the nail of the same finger; they are serologically negative. There may be a swollen finger with loss of the skin markings-a sort of dactylitis, again serologically negative. (2) Those with a much more severe process which produces loss of movement in the spine and changes in the sacroiliac joints much the same as those in ankylosing spondylitis; unlike ankylosing spondylitis, it produces severe deformity often with ankylosis in peripheral joints. Many of the finger joints become deformed and ankylosed. (3) Those cases indistinguishable from rheumatoid arthritis although the majority are sero-negative. The Stevens Johnson syndrome produces acute effusions, particularly in large joints. It is sometimes associated with the rash of erythema multiforme, always with ulceration in the mouth and genital tract; the mouth ulcers are accompanied by sloughing, unlike those of Beh9et's syndrome which we come to next. BehCet's syndrome, originally described as a combination of orogenital ulceration with relapsing iritis, is now expanded to include skin lesions, other eye lesions, lesions of the central nervous system, thrombophlebitis migrans, and arthropathy (occurring in 64 per cent). The onset is acute, often affecting only a single joint and settling without residual trouble. Choice of drugs in the treatment of rheumatoid arthritis Dr Dudley Hart, M.D., F.R.C.P. (Consultant physician, Westminster Hospital and Medical School) There are many potential drugs for the treatment of rheumatoid disease, but what are we treating in this disorder? Pain in rheumatoid arthritis is but one of the symp- toms.

Through this use, millions of consumers using antianxiety preparations are potentially exposed to kava kava. A traditional beverage of various Pacific Basin countries, kava clearly has psychoactive properties. The effects of its long-term consumption have not been documented adequately; preliminary studies suggest possibly serious organ system effects. The potential carcinogenicity of kava and its principal constituents are unknown. INPUT FROM GOVERNMENT AGENCIES/INDUSTRY The U.S. Pharmacopeia is in the process of reviewing kava kava.

References I. Introduction and Use of the UC‐Denver Formulary Basic Definitions: Anesthesia: central nervous system depression that provides amnesia, unconsciousness and immobility in response to a painful stimulation. Drugs that produce anesthesia may or may not provide analgesia (1, 2). Analgesia: The absence of pain in response to stimulation that would normally be painful. An analgesic drug can provide analgesia by acting at the level of the central nervous system or at the site of inflammation to diminish or block pain signals (1, 2). Sedation: A state of mental calmness, decreased response to environmental stimuli, and muscle relaxation. This state is characterized by suppression of spontaneous movement with maintenance of spinal reflexes (1). Animal anesthesia and analgesia are crucial components of an animal use protocol. This document is provided to aid in the design of an anesthetic and analgesic plan to prevent animal pain whenever possible. However, this document should not be perceived to replace consultation with the university’s veterinary staff. As required by law, the veterinary staff should be consulted to assist in the planning of procedures where anesthetics and analgesics will be used to avoid or minimize discomfort, distress and pain in animals (3, 4). Prior to administration, all use of anesthetics and analgesic are to be approved by the Institutional Animal Care and Use Committee (IACUC).

Abstract Background: Several recent trials indicate low-dose ketamine produces rapid antidepressant effects. However, uncertainty remains in several areas: dose response, consistency across patient groups, effects on suicidality, and possible biases arising from crossover trials. Methods: A systematic search was conducted for relevant randomized trials in Medline, Embase, and PsycINFO databases up to August 2014.

  • Guideline for Preoperative Medication Management
    Guideline: Preoperative Medication Management Guideline for Preoperative Medication Management Purpose of Guideline: To provide guidance to physicians, advanced practice providers (APPs), pharmacists, and nurses regarding medication management in the preoperative setting. Background: Appropriate perioperative medication management is essential to ensure positive surgical outcomes and prevent medication misadventures.1 Results from a prospective analysis of 1,025 patients admitted to a general surgical unit concluded that patients on at least one medication for a chronic disease are 2.7 times more likely to experience surgical complications compared with those not taking any medications. As the aging population requires more medication use and the availability of various nonprescription medications continues to increase, so does the risk of polypharmacy and the need for perioperative medication guidance.2 There are no well-designed trials to support evidence-based recommendations for perioperative medication management; however, general principles and best practice approaches are available. General considerations for perioperative medication management include a thorough medication history, understanding of the medication pharmacokinetics and potential for withdrawal symptoms, understanding the risks associated with the surgical procedure and the risks of medication discontinuation based on the intended indication. Clinical judgement must be exercised, especially if medication pharmacokinetics are not predictable or there are significant risks associated with inappropriate medication withdrawal (eg, tolerance) or continuation (eg, postsurgical infection).2 Clinical Assessment: Prior to instructing the patient on preoperative medication management, completion of a thorough medication history is recommended – including all information on prescription medications, over-the-counter medications, “as needed” medications, vitamins, supplements, and herbal medications. Allergies should also be verified and documented.
