Ciprofloxacin, previously available orally (Cipro - Medical Letter, 30:11, 1988) and for ophthalmic use (Ciloxan - Medical Letter, 33:52, May 31, 1991), is now the first fluoroquinolone antibiotic to become available in the USA in an intravenous (IV) formulation. Cipro I.V. (Miles) is being promoted as an alternative to third-generation cephalosporins, aminoglycosides, and other drugs used for treatment of serious infections.

Cefditoren pivoxil (Spectracef — TAP), a new oral third-generation cephalosporin, has been approved by the FDA for treatment of acute exacerbations of chronic bronchitis, pharyngitis, tonsillitis and uncomplicated skin and soft tissue infections in adults and children 12 or more years old.

Emrosi (Journey), an oral, low-dose, biphasic-release formulation of the tetracycline antibiotic minocycline, has been approved by the FDA for once-daily treatment of inflammatory lesions of rosacea (papules and pustules) in adults. Low-dose, biphasic-release doxycycline (Oracea, and generics) has been available for years for treatment of papulopustular rosacea.

Fluoxetine (Prozac - Dista), a phenylpropylamide, is the first serotonin-reuptake blocker introduced in the USA for treatment of . It is being promoted as causing fewer adverse effects than other antidepressants. Claims of greater safety and patient tolerability have often been made for new non-tricyclic antidepressants in recent years, but unpredicted adverse effects have emerged with widespread use, including priapism with trazodone (Desyrel - Medical Letter, 26:35, 1984) and fatal hemolytic anemia with nomifensine (Merital - Medical Letter, 27:73, 1985).

Granisetron, a serotonin (5-HT) antagonist similar to ondansetron, was recently approved by the US Food and Drug Administration for prevention of nausea and vomiting due to cancer chemotherapy. Although available in an oral formulation in other countries, granisetron is available here only for intravenous (IV) use.

The FDA has approved Altuviiio (Sanofi), a von Willebrand Factor (VWF)-independent, recombinant factor VIII concentrate, for routine prophylaxis, on-demand treatment to control bleeding episodes, and perioperative management of bleeding in children and adults with hemophilia A. The manufacturer claims that Altuviiio, which was previously called efanesoctocog alfa, delivers normal to near-normal factor VIII levels for most of the week with once-weekly intravenous dosing.

Toripalimab-tpzi (Loqtorzi – Coherus Biosciences), a programmed death receptor-1 (PD-1)-blocking antibody, has been approved by the FDA for use in combination with cisplatin and gemcitabine for first-line treatment of recurrent locally advanced or metastatic nasopharyngeal carcinoma and for use as monotherapy for treatment of recurrent unresectable or metastatic nasopharyngeal carcinoma in adults with disease progression on or after platinum-based chemotherapy.

Most respiratory tract infections are caused by viruses. Bacterial respiratory tract infections are usually treated empirically with antibiotic therapy that targets the most probable causative pathogens. Recommended antibiotic regimens for outpatient treatment of some common respiratory tract infections are listed in Table 1 for adults and Table 2 for children.

Zanamivir, a neuraminidase inhibitor taken by inhalation, has been approved by the FDA for treatment of influenza. Oseltamivir phosphate, an oral neuraminidase inhibitor, will probably be approved soon.
