Clarithromycin 250mg, 500mg Tablets [US: Biaxin]

Clarithromycin belongs to a group of medicine called macrolide antibiotics. Antibiotics stop the growth of bacteria (bugs) which cause infections. Clarithromycin tablets are used to treat following infections: chest infections such as bronchitis and pneumonia, throat and sinus infections, skin and soft tissue infections, helicobacterpylori infections associated with duodenal ulcers.

Order Generic Nizoral (Ketoconazole) No Prescription 200mg

Ketoconazole can increase the concentrations of astemi-zole and terfenadine by inhibition of CYP3A4. High concentrations of terfenadine can cause cardiac toxicity. Increased plasma concentrations of unmetabolized terfenadine prolong the QT interval and carry the risk of torsade de pointes and other fatal ventricular arrhythmias.

Fluconazole (Diflucan) Order No Prescription 50/100/150/200mg

Concurrent administration of fluconazole probably causes increased exposure to amitriptyline. Three reports of adults have shown increased amitriptyline plasma concentrations with concurrent administration of fluconazole; in one patient, a 57-year-old woman, the QT interval was prolonged and torsade de pointes occurred. In vitro studies and experiments in animals have given conflicting results relating to potential antagonism between the effects of fluconazole and amphotericin on Candida species.

Specific Anti-Infective Agents

Clinicians should be familiar with the general classes of antibiotics, their mechanisms of action, and their major toxicities. The differences between the specific antibiotics in each class can be subtle, often requiring the expertise of an infectious disease specialist to design the optimal anti-infective regimen. The general internist or physician-in-training should not attempt to memorize all the facts outlined here, but rather should read the pages that follow as an overview of anti-infectives. The chemistry, mechanisms of action, major toxicities, spectrum of activity, treatment indications, pharmacokinetics, dosing regimens, and cost are reviewed.

Treatment of HIV / AIDS

The goal of antiretroviral therapy is to achieve the maximum suppression of HIV replication (HIV RNA level that is less than the lower limit of quantitation). Secondary goals include an increase in CD4 lymphocytes and an improved quality of life. The ultimate goal is decreased morbidity and mortality.

Antimicrobial Regimen Selection

A generally accepted systematic approach to the selection and evaluation of an antimicrobial regimen is shown in Table Systematic Approach for Selection of Antimicrobials. An «empiric» antimicrobial regimen is begun before the offending organism is identified, while a «definitive» regimen is instituted when the causative organism is known. The use of combinations to prevent the emergence of resistance is widely applied but not often realized. The only circumstance where this has been clearly effective is in the treatment of tuberculosis.

Infectious disorders

Infectious diseases comprise those illnesses that are caused by microorganisms or their products. Clinical manifestations of infection occur only when sufficient tissue injury has been inflicted directly by microbial products (e.g., endotoxins and exotoxins), or indirectly by host responses (e.g., cytokines and hydrolytic enzymes released by polymorphonuclear leukocytes). Despite the extraordinary recent advances that have occurred in therapeutics for infectious diseases, a number of basic principles should be followed to prescribe antimicrobials and vaccines is an optimal manner.
