Conversion from IV to PO antimicrobials in select patients results in cost savings for the facility as well as aim for positive clinical outcomes such as shortened hospital stay, reduced risk of line-related infections and adverse events and no IV related … Oral fluoroquinolone therapy, for example, has a cure rate in the literature of between 60 to 80 percent.Other studies have found similar results of efficacy with different agents. The study was also led by physicians in specialist centres.The overuse of antibiotics has contributed to the emergence and dissemination of antimicrobial-resistant nosocomial and community pathogens.
The aim of the review was to give clinicians the confidence to change children to oral antibiotics and to send them home earlier. Antibiotic duration and timing of the switch from intravenous to oral route for bacterial infections in children: systematic review and guidelines. Clinicians should also exercise caution when using TMP-SMX in patients who have chronic renal insufficiency because of an increased risk of hyperkalemia.
Clindamycin-induced diarrhea is the most common adverse effect and occurs in up to 20 percent of patients.Clindamycin’s side effects may occur more frequently in comparison with other oral antibiotic agents.When using trimethoprim/sulfamethoxazole (TMP-SMX), be cautious about administration of the drug in treating geriatric patients, particularly those taking concurrent inhibitors of the renin-angiotensin system. Intravenous antibiotics allow higher serum antibiotic concentration and thus higher bone antibiotic concentration.
In contrast, in situations in which the affected bone and surrounding soft tissue are primarily viable, then the route of antibiotic administration is an important consideration.With this concession in mind, we would certainly argue that there is no clear evidence indicating a requirement for IV antibiotics in the treatment of osteomyelitis. Bioavailability = the measure of the amount of an orally administered medication that reaches the bloodstream. If the implant is not removable, usually because of bone instability, place the patient on suppressive oral therapy until the bone is stable. Podiatry Today is a trademark of HMP.
Think metronidazole, rifampicin, doxycycline, ciprofloxacin and clindamycin (which all have good tissue penetration) Oral antibiotics with a bioavailability of at least 90 percent absorption are generally considered equivalent to intravenous antibiotics from a pharmacokinetic standpoint.Additionally, studies have provided evidence that fluoroquinolones, trimethoprim/sulfamethoxazole, linezolid and other oral agents can readily achieve levels in bone that exceed the minimum inhibitory concentration (MIC) at about 50 percent of serum.Beyond theoretical pharmacokinetics, the clinical data shows the efficacy of oral agents. IV-to-oral switching programs for antibiotics were implemented in several countries in the 1990s.
