LEVITRA (Vardenafil Hcl) Tablets
LEVITRA (vardenafil HCl) Tablets DESCRIPTION LEVITRA® is an oral therapy for the treatment of erectile dysfunction. This monohydrochloride salt of vardenafil is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). Vardenafil HCl is designated chemically as piperazine, 1-[[3-(1,4-dihydro-5- methyl-4-oxo-7-propylimidazo[5,1-f][1,2,4]triazin-2-yl)-4- ethoxyphenyl]sulfonyl]-4-ethyl-, monohydrochloride and has the following structural formula: O O HN N x HCl x 3H2O N N O S O N N Vardenafil HCl is a nearly colorless, solid substance with a molecular weight of 579.1 g/mol and a solubility of 0.11 mg/mL in water. LEVITRA is formulated as orange, round, film-coated tablets with "BAYER" cross debossed on one side and "2.5", "5", "10", and "20" on the other side corresponding to 2.5 mg, 5 mg, 10 mg, and 20 mg of vardenafil, respectively. In addition to the active ingredient, vardenafil HCl, each tablet contains microcrystalline cellulose, crospovidone, colloidal silicon dioxide, magnesium stearate, hypromellose, polyethylene glycol, titanium dioxide, yellow ferric oxide, and red ferric oxide. CLINICAL PHARMACOLOGY Mechanism of Action Penile erection is a hemodynamic process initiated by the relaxation of smooth muscle in the corpus cavernosum and its associated arterioles. During sexual stimulation, nitric oxide is released from nerve endings and endothelial cells in the corpus cavernosum. Nitric oxide activates the enzyme guanylate cyclase resulting in increased synthesis of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the corpus cavernosum. The cGMP in turn triggers smooth muscle relaxation, allowing increased blood flow into the penis, resulting in erection. -
Trazodone Is Not As Effective As Other Antidepressants in Treating a Patient with Major Depressive Disorder
Case Report Taiwanese Journal of Psychiatry (Taipei) Vol. 26 No. 4 2012 • 311 • Trazodone Is Not as Effective as Other Antidepressants in Treating a Patient with Major Depressive Disorder Kah Kheng Goh, M.D.1, Weng-Kin Tam, M.D.1, Winston W. Shen, M.D.1, 2* Background: Trazodone in clinical use is ineffective because of its sed ation to let patient receive an adequate dose for treating a patient with major depressive disorder. We are report a case report to demonstrate this clinical effi cacy issue in the treatment with trazodone. Case Report: A 83-year old male Taiwanese patient had suffered from MDD for six months. He did not response to the treatment of trazodone 150 mg/day for four months, but consequently, he responded to the treatment of milnacipran 100 mg/day or mirtazapine 30 mg/day. Conclusion: Psy- chiatrists in Taiwan should be alert to the fact that trazodone is not as effective as other antidepressants, and that trazodone should not be prescribed as a single anti- depressant in treating an MDD patient.

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. -

Mechanism of Drug-Induced Qt Interval Prolongation
ABSTRACT Torsades de pointes (TdP) is a polymorphic ventricular tachycardia characterized by a distinctive pattern of undulating QRS complexes that twist around the isoelectric line. TdP is usually self-terminating or can subsequently degenerate into ventricular fibrillation, syncope, and sudden death. TdP has been associated with QT interval prolongation of the electrocardiogram; therefore, the QT interval has come to be recognized as a surrogate marker for the risk of TdP. International guidelines have been developed to harmonize both the preclinical and clinical studies for the evaluation of drug-induced TdP. However, currently preclinical in vitro and in vivo methods as well as biomarkers for proarrhythmias have been imperfect in predicting drug-induced TdP in humans. It is clear that relevant biomarkers together with appropriate models are needed to assess the arrhythmic risk of new chemical entities. The goal of the present dissertation is to create rabbit with myocardial failing heart as an in vivo animal model to predict TdP in humans and to determine mechanism(s) underlying TdP in this model. Electrocardiograms were recorded from bipolar transthoracic leads in 7 conscious healthy rabbits previously trained to rest quietly in slings. The RR and QT relationship, ii QT=2.4RR0.72 (r2=0.79, p < 0.001) was obtained by slowed the heart rate with 2.0 mg/kg zatebradine, and the algorithm for removing effect of heart rate on QT is QTc = QT/(RR)0.72. QTc lengthened significantly in all conscious rabbits given intravenous cisapride, dofetilide or haloperidol (p < 0.05), and QTc did not change with DMSO (vehicle control), propranolol or enalaprilat. -

ED is a serious problem affecting both the psychosocial state of the man and his partner [1]. In the ED development, the role of bad habits is great, for example, among smoking men it occurs 20% more often than among nonsmokers [2,3]. ED is associated with various comorbid conditions such as hypertension, hyperlipidemia, metabolic syndrome, lower urinary tract symptoms (LUTS) or benign prostatic hyperplasia (BPH), cardiovascular disease, psychological factors, diabetes mellitus, post-radical prostatectomy, antidepressant medication and antihypertensive drugs, etc. (Table 1).
