- It can be a form of either topical administration or systemic administration, as the drugs thus locally delivered can go on to have either purely local or systemic effects. Nasal sprays are locally acting drugs such as decongestants for cold and allergy treatment, whose systemic effects are usually minimal.
- Most drugs (or metabolites) are excreted by the kidneys. Some drugs are eliminated by the liver in the bile and excreted in feces. • Enterohepatic circulation can occur (drug excreted in bile is absorbed by the gut and re-excreted by the liver in bile).
Topical antibiotics are antibiotics that have been manufactured into a cream or an ointment and can be applied directly to the skin. Antibiotics are medicines that destroy or inhibit the growth of susceptible bacteria.

- As most cases of uncomplicated cellulitis are caused by Strep, they are still best treated with a penicillin or cephalosporin (e.g., Keflex) type of antibiotic, known as beta-lactams. These antibiotics are much better than TMP-SMX for strep infections. These drugs are also safer than clindamycin, for widespread use.
- Polymyxin B sulfate - bacitracin zinc - gramicidin contains a combination of antibiotics used for the treatment of certain types of infections caused by bacteria. The topical ointment can be used to treat certain skin infections such as infected wounds, burns, skin grafts, boils, and acne.
