ABSTRACT Total use of anti-secretory medication (H2 blockers and proton pump inhibitors) is increasing rapidly, but knowledge of factors related to the increasing use is sparse.
To describe development in the use of anti-secretory medication between 1993 and 2002 at a population level.
We extracted data on use of anti-secretory medication (H2-blockers and proton pump inhibitors) and ulcerogenic drugs, demographic data, and data on gastroscopy and endoscopically verified oesophagitis and peptic ulcer diagnoses, from three large population-based databases covering the County of Funen, Denmark 1990-2002 (population 470,000).
Between 1993 and 2002 incidence of first time users was stable at 16.7/1000 persons/year. Total amount of consumed anti-secretory medication increased from 10.5 DDD/1000 persons/day to 25.2 DDD/1000 persons/day. Ninety per cent of the increase was related to long-term use of anti-secretory medication (> or = 180 DDD/patient/year). In 1993 21% of the anti-secretory medication was used by patients with oesophagitis, this increased to 28% in 2002. The proportion of medication used by peptic ulcer patients decreased from 29% in 1993 to 19% in 2002.
Total use of anti-secretory medication increased as a result of more extensive long-term use, and most of the medication was used by patients without diagnosed peptic ulcer or oesophagitis.

    • "Neither cimetidine nor nizatidine ranked among the top 200 drugs sold in 2007. [218] Although this liberal use of PPI has been recently recommended by many guidelines for dyspepsia [219] [220], it is well documented that these drugs are often inappropriately prescribed for minor symptoms and without clear indications, where the effects of acid-suppressive therapy is controversial [212] [214] [221] [222] [223] [224] [225]. As a result, a large proportion of patients currently prescribed PPI do not have acid-related symptoms and thus, have no true indication for such therapy. "

    ABSTRACT: The homeopathic model applies the secondary action or vital reaction of the organism as a therapeutic method and thus prescribes treatment by similitude, which consists in administering to ill individuals substances that cause similar symptoms in healthy individuals. The vital, homeostatic or paradoxical reaction of the organism might be explained scientifically by means of the rebound effect of modern drugs, which might cause fatal iatrogenic events after discontinuation of antipathic (a term used in alternative medicine for palliative treatment, also known as enantiopathic) treatment. Although the rebound effect is studied by modern pharmacology, it is poorly communicated to and discussed among healthcare professionals, who are thus deprived of information needed for the safe management of modern drugs. This article presents an up-to-date review on the rebound effect of modern drugs that grounds the homeopathic principle of healing and calls the attention of doctors to this type of adverse effect that is usually unnoticed. The rebound effect of modern palliative drugs, which was pointed out by Hahnemann more than two centuries ago, might cause fatal adverse events and is illustrated by the examples of acetylsalicylic acid, anti-inflammatory agents, bronchodilators, antidepressants, statins, proton-pump inhibitors, etc. Although the rebound effect is expressed by a small fraction of (susceptible) individuals and might be avoided by gradual tapering of antipathic drugs, it exhibits epidemiologic importance as a function of the massive use of such palliative drugs and the lack of knowledge in its regard.

    • "There is no consensus or agreed defi nition on what constitutes long term PPIs prescription. The defi nition has varied: from one repeated prescription over 12 months to continuous therapy for periods ranging from 4 to >12 months (Table 1) (Ryder et al 1994; Roberts and Bateman 1995; Rubin et al 1995; Goudie et al 1996; Ahnfeldt-Mollerup et al 1997; Boutet et al 1999; Hungin et al 1999; Prach et al 1999; Vetvik and Straand 2001; Hurenkamp et al 2002; Chen et al 2003; Jacobson et al 2003; Majumdar et al 2003; Lassen et al 2004; Raghunath and Hungin 2004; Tsai et al 2004; Raghunath et al 2005). GERD is a very common complaint when considering the management of treatment with PPIs in the population over 65 years of age. "

    ABSTRACT: The prevalence of gastroesophageal reflux disease (GERD) increases with age and elderly are more likely to develop severe disease. Older patients often complain of less severe or frequent heartburn than younger patients and they may present with atypical symptoms such as dysphagia, weight loss, or extraesophageal symptoms. Proton pump inhibitors (PPIs) are central in the management of GERD and are unchallenged with regards to their efficacy. They are considered safe and more effective than histamine receptor antagonists for healing esophagitis and for preventing its recurrence using a long term maintenance treatment. PPI have minimal side effects and few slight drug interactions and are considered safe for long term treatment. Pantoprazole is significantly effective both for acute and long-term treatment with excellent control of relapse and symptoms. It is well tolerated even for long-term therapy and its tolerability is optimal. Pantoprazole shows to have minimal interactions with other drugs because of a lower affinity for cytocrome P450 than older PPIs. Although the majority of elderly has concomitant illnesses and receive other drugs, this does not adversely effect the efficacy of pantoprazole because of its pharmacokinetics, which are independent of patient age. Clinical practice suggests that a low dose maintenance of PPIs should be used in older patients with GERD.

    ABSTRACT: A utility interactive sinewave pulse width modulation soft commutation inverter using trench-gate IGBTs for the solar photovoltaic power conversion conditioning and processing with a high frequency transformer link is presented for residential applications. As compared with the conventional full-bridge hard switching sinewave PWM inverter with a high frequency AC link, the simplest single-ended quasi-resonant soft switching sinewave modulated inverter with a sinewave duty cycle pulse control scheme is implemented, resulting in size and weight reduction, low-cost and efficiency. This paper presents a prototype circuit and system of the single-ended zero voltage soft switching sinewave PWM inverter for solar power conditioner, along with its operating principle and unique features. In addition to these, this paper proposes a control implementation to deliver high quality output current. Major design of each component and the power loss analysis under actual power conditioning and processing is also discussed and evaluated from an experimental point of view. A newly-developed utility-interactive sinewave power conditioning processor which has 92.5% efficiency at 4 kW output is demonstrated herein. It is designed for 540 mm-300 mm-125 mm in size and 20 kg in weight.
