Orlynvah (Iterum Therapeutics), an oral fixed-dose combination of the thiopenem antibacterial prodrug sulopenem etzadroxil and the renal tubular transport inhibitor probenecid, has been approved by the FDA for treatment of uncomplicated urinary tract infections (uUTIs) caused by susceptible isolates of Escherichia coli, Klebsiella pneumoniae, or Proteus mirabilis in women who have limited or no alternative oral antibacterial treatment options. It is the first oral penem-containing product to be approved in the US.

Drugs for gout are used to reduce the pain and inflammation of acute flares, decrease the frequency of exacerbations, and lower serum urate levels to prevent recurrent flares, development of tophi, and joint damage.

This article includes recommendations for management of most sexually transmitted infections (STIs) other than HIV and viral hepatitis. Some of the indications and dosages recommended here have not been approved by the FDA (see Table 1).

The FDA has approved lesinurad (Zurampic – Ironwood), a uric acid transporter 1 (URAT1) inhibitor, for adjunctive treatment of gout-associated hyperuricemia in patients whose serum uric acid levels fail to reach goal with xanthine oxidase inhibitor monotherapy.

The goals of gout treatment are threefold: treating acute inflammation, preventing flares, and lowering serum urate levels.

Until the recent introduction of febuxostat (Uloric), no new drugs had been marketed for treatment of gout in the past 40 years. Colchicine, which has been available for decades as an unapproved drug, has now been approved by the FDA (Colcrys) for treatment and prophylaxis of gout flares. It was approved earlier only in combination with probenecid (Colbenemid, and others). The goals of gout treatment are three-fold: treating acute disease, preventing flares and reducing uric acid stores.

Doripenem (Doribax - Ortho-McNeil Janssen), an intravenous (IV) carbapenem antibiotic with a spectrum of activity similar to that of imipenem and meropenem, has been approved by the FDA for treatment of complicated intra-abdominal and urinary tract infections. Use of doripenem for treatment of nosocomial pneumonia, including ventilator-associated pneumonia, is still under FDA review.

Antiviral prophylaxis is indicated for influenza exposures that occur before (or less than 2 weeks after) vaccination with inactivated vaccine, or in years when circulating strains differ from those included in the vaccine. Antiviral drugs can also be used for treatment of patients who develop symptoms of influenza, regardless of vaccination status.

When patents expire on brand-name drugs and generic formulations become available, patients and managed care organizations may express a preference for the lower-cost generics. Are they equivalent to the brand-name product?

Results of recently completed clinical trials have led to some changes in recommendation for treatment of human immunodeficiency virus (HIV) and other infections associated with AIDS.

A growing number of clinical trials now permits some consensus on the treatment of human immunodeficiency virus (HIV) and other infections associated with acquired immune deficiency syndrome (AIDS) in adults.

Lyme disease, a multisystem bacterial transmitted by Ixodid ticks, particularly in early summer, continues to be a common problem in the USA and many other countries. Since last year (Medical Letter, 30:65, 1988), some new information has become available, but data on the choice, dosage and duration of antibiotic therapy are still available, but data on the choice, dosage and duration of antibiotic therapy are still limited.

Lyme Disease, a multisystem inflammatory disorder transmitted by lxodid ticks and caused by the spirochete Borrelia burgdorferi, is now the most common tick-transmitted illness in the USA. It has been reported in 32 states and on all other continents except Antarctica. Infected ticks have been found not only in wooded areas, but also on well-maintained suburban lawns (RC Falco and D Fish, Am J Epidemiol, 127:826, April 1988). Optimal treatment for this newly discovered disease is still being determined, but some recommendations based on published experience and work in progress can be made.

Cefuroxime axetil (Ceftin - Glaxo), an oral form of the second-generation parenteral cephalosporin cefuroxime (Zinacef), was recently marketed in the USA. Previously available oral cephalosporins are the first-generation drugs cephalexin (Keflex; and others), cephradine (Anspor; and others) and cefadroxil (Duricef; and others), and the second-generation cefaclor (Ceclor); second-generation cephalosporins have more activity against gram-negative bacteria.
