Teriparatide(recombinant human PTH1-34, 20 μg daily subcutaneous injection)has been approved for osteoporosis patients at high risk of fracture in many countries including Japan. Teriparatide daily injection therapy has been reported to increase BMD, improve microarchitecture of bone, and reduce the risk of new vertebral fractures and that of non-vertebral fractures. Pharmakokinetic(PK)study after a single Teriparatide injection of the daily dose in healthy Japanese postmenopausal women(n=18)revealed very rapid achievement of peak blood level(median of tmax=0...

Downregulation of the unfolded protein response mediates proteasome inhibitor resistance in multiple myeloma. The Human Immunodeficieny Virus protease inhibitor nelfinavir activates the unfolded protein response in vitro. We determined dose-limiting toxicity and recommended dose for phase II of nelfinavir in combination with the proteasome inhibitor bortezomib. Twelve patients with advanced hematologic malignancies were treated with nelfinavir (2500-5000 mg/day p.o., days 1-14, 3+3 dose escalation) and bortezomib (1...

Patients with opioid pretreatment can be divided into different groups.While patients after successful drug addiction treatment with or without drug replacement therapy usually not require an extensive perioperative pain therapy, patients with persistent chronic pain and patients with an existing opioid addiction regularly are challenging for the anesthetist. Important pathophysiological issues among the patients include opioid tolerance, opioid-induced hyperalgesia (OIH) as well as acute withdrawal symptomes...

BACKGROUND: Pharmacogenetics deals with hereditary factors which influence the pharmacodynamics and pharmacokinetics of drugs leading to individual diverse reactions. Also in anesthesiology differences in the pharmacogenetics of patients can lead to relevant alterations in the pharmacodynamics of drugs. AIM: This article provides a summary of polymorphisms relevant to commonly used anesthetic agents and the clinical relevance in patients treated with these compounds...

To achieve a fast onset and a sufficiently long duration of action in the long-term treatment of angina pectoris a composite dosage form was developed, consisting of a fast-release initial dose Di and a slow-release maintenance dose Dm. The product is designed to be given once daily in the morning to achieve sufficiently high blood levels for clinical response during day-time with declining blood levels during night-time to avoid tolerance. In view of its pharmacokinetic properties, the antianginal drug isosorbide-5-nitrate (IS-5-N) was selected as the model substance...

The main indications for diuretic treatment of renal patients are edema and hypertension. Pharmakokinetics and pharmacodynamics of diuretics are altered in patients with proteinuria and/or impaired renal function. These patients exhibit avid sodium retention. Diuretics are partially inactivated by binding to proteins in tubular fluid. The natriuretic response to diuretics is limited by counter-regulation, specifically increased proximal tubular reabsorption in response to hypovolemia and increased distal tubular sodium reabsorption in response to increased sodium load...

Metoprolol is available for clinical use as a racemic mixture. The S-(-)-metoprolol enantiomer is the one expressing higher activity in the blockade of the β(1)-adrenergic receptor. The α-hydroxymetoprolol metabolite also has activity in the blockade of the β(1)-adrenergic receptor. The present study describes the development and validation of a stereoselective method for sequential analysis of metoprolol and of α-hydroxymetoprolol in plasma using high-performance liquid chromatography with tandem mass spectrometry (LC-MS/MS)...

INTRODUCTION: The benzoporphyrine derivative verteporfin has lost its importance to the treatment of the most frequent neovascular eye diseases. Nevertheless, it is still mandatory to define the remaining applications, role, and potential of verteporfin in ocular photodynamic therapy (PDT), including the dosages of administration, effectiveness, and safety profile. AREAS COVERED: Although verteporfin PDT has forfeited the first-line status and value of treating subfoveal choroidal neovascularization (CNV) due to age-related macular degeneration or pathologic myopia, the treatment remains the standard of care for choroidal haemangioma and polypoidal choroidal vasculopathy...

The principal aims of therapeutic management of the child, adolescent and adult with type 1 diabetes are to allow good quality of life and to avoid long-term complications by maintaining blood glucose concentrations close to the normal range and an HbA1c level under 7%. The number of daily insulin injections, 2 or > or =4 or pumps, by itself does not necessarily give better results, but the 4-injection regimen allows greater freedom, taking into account that the proper insulin adjustment is difficult before adolescence...

IL-1RA is a naturally occurring antagonist of the pro-inflammatory cytokine interleukin-1 (IL-1) with high therapeutic promise, but its pharmacokinetic remains poorly documented. In this report, we describe the radiolabeling of recombinant human interleukin-1 receptor antagonist (rhIL-1RA) with fluorine-18 to allow pharmacokinetic studies by positron emission tomography (PET). rhIL-1RA was labeled randomly by reductive alkylation of free amino groups (the epsilon-amino group of lysine residues or amino-terminal residues) using [(18)F]fluoroacetaldehyde under mild reaction conditions...

70 years have passed since the first isolation of the naphthodianthrones hypericin and pseudohypericin from Hypericum perforatum L. Today, they continue to be one of the most promising group of polyphenols, as they fascinate with their physical, chemical and important biological properties which derive from their unique chemical structure. Hypericins and their derivatives have been extensively studied mainly for their antitumor, antiviral and antidepressant properties. Notably, hypericin is one of the most potent naturally occurring photodynamic agents...

Noninvasive hormone assays provide a way to determine an animal's health or reproductive status without the need for physical or chemical restraint, both of which create unnecessary stress for the animal, and can potentially alter the hormones being measured. Because hormone metabolism is highly species-specific, each assay must be validated for use in the species of interest. Validation of noninvasive steroid hormone assays has traditionally required the administration of relatively high doses of radiolabelled compounds (100 µCi or more of (14)C labeled hormone) to permit subsequent detection of the excreted metabolites in the urine and feces...

This article deals with specific aspects of the patient with sepsis and his treatment. With adequate therapy (antibiotics started within the first hour, early goal-directed therapy) initiated as early as possible, the patient with community-aquired severe sepsis in the emergency department has a considerable better chance to survive than the patient with prolonged severe sepsis in the ICU. The average age of patients with severe sepsis and septic shock treated at the ICU is rising, with consequences like oligosymptomatic presentation, altered pharmakokinetics according to older-age-induced reduced organ functions and prolonged stay at the ICU due to comorbidity...

Atypical antipsychotics are now widely used in the acute and long-term treatment in bipolar disorder. The role of atypical antipsychotics as acute agents, add-on medications; or as primary mood stabilizers in different phases of bipolar disorder is an important current research tendency. However, in bipolar disorder the mostly used indication of quetiapine is the management of acute manic phases, clinical data and the actual research results suggest that it may have both antidepressant and long-term antimanic effects...

N-Chlorotaurine (NCT) is a promising endogenous agent for topical treatment of infections. We tested the tolerability and pharmakokinetics of NCT in the bovine mammary glands in a phase 1 study. Three concentrations of NCT in water (0.1%, 1.0%, 2.0%) were administered intramammarily in each of two cows. Into two quarters of the udder 100 ml NCT was injected into each twice daily for 5 d, while 0.9% NaCl was injected into the other two quarters in a randomized and blinded manner. Samples of milk were taken to determine the number of leucocytes and the activity of NCT, and samples of urine and blood to determine the taurine and chloride concentration...

BACKGROUND: Although the value of digitalis glycosides in the treatment of heart failure is limited, approximately 255 million DDDs of digitalis glycosides (DGs) were prescribed in Germany in 2004. METHOD: The authors analyzed data from adverse drug reactions (ADRs) resulting in hospitalization in the four German Pharmacovigilance Centers (PVCs) associated with DGs between 2000 and 2004. All patients with an at least "probable" ADR were included. RESULTS: Out of 3,092 ADR patients, in 314 patients (10...
