While the American Academy of Dermatology has established guidelines regarding acne treatment in general, the variability among acne treatments, even within a given class, prevents establishment of a straightforward regimen. For example, moderate to severe acne is generally treated with an oral antibiotic, although several options are available—both across and within antibiotic classes. The aim of this review is to report the efficacy and safety data available for commonly prescribed oral antibiotics. While there are currently no data to support superiority of one drug over another, there are substantial differences in safety profiles and brand-specific features that may make one antibiotic preferable over another. Acne vulgaris is the most common skin disorder encountered in dermatology practice in the United States, affecting approximately 85 percent of teenagers and sometimes persisting into and throughout adulthood. Acne is a disease of the pilosebaceous unit with a complex pathology. Currently, there are thought to be at least four synergistic, biological mechanisms that contribute to acne pathogenesis, which is primarily inflammatory in nature. Nonetheless, there are a variety of therapeutics available, each targeting one or more of these pathogenic processes. Pharmacological treatments for acne include a variety of topical and systemic agents. Topical treatment e. This review will focus on the efficacy and safety of oral antibiotics that are commonly used or available to treat acne. Treatment algorithm for the management of acne vulgaris in adolescents and young adults 4. The American Academy of Dermatology supports the use of oral antibiotics for treating moderate and severe acne, and oral antibiotics have been a mainstay of acne treatment for over 50 years. Apart from the tetracycline class of antibiotics doxycycline, minocycline and sarecycline , the potential benefit of oral antibiotics often outweighs the potential risks, and they remain a mainstay of moderate-to-severe acne treatment. With currently available clinical studies and data, there is a consensus that no one antibiotic is superior to another regarding efficacy. Studies included were those that evaluated treatment response in patients with acne. Among acne studies, there are several metrics of efficacy that are commonly reported. Similarly, the absolute or percent change in non-inflammatory lesions i. Change in inflammatory lesions will be the emphasis of efficacy results for this review. This review will begin by summarizing studies of tetracycline-class antibiotics, followed by azithromycin and trimethoprim-sulfamethoxazole. The tetracyclines. Among oral antibiotics used to treat acne, tetracycline has the longest history, having been discovered in the s and FDA-approved in While effective, its side effect profile, need for frequent dosing, and susceptibility to antibiotic resistance have made it unpopular, and it is no longer considered a standard treatment regimen. In addition to their antibacterial action, the tetracyclines demonstrate multiple anti-inflammatory properties. While all tetracyclines share these anti-microbial and anti-inflammatory MOAs, there is significant variability regarding side effect profiles, discussed below, that account for the preferential prescription of one over the other. The first tetracycline derivative to come to market was doxycycline, approved by the FDA in and still one of the most commonly used antibiotics in clinical practice. Doxycycline hyclate is more water-soluble than doxycycline monohydrate and might be more ulcerogenic and susceptible to causing gastrointestinal GI -associated side effects. The side effect profile of doxycycline is superior to that of tetracycline, although there are potential adverse events that should be taken into consideration Table 2. Doxycycline is amenable to being taken with food—which might lessen GI discomfort— although its absorption is reduced by approximately 20 percent with food. Pill esophagitis—inflammation or esophageal ulcers—can occur when taking doxycycline. Like other side effects, however, it is largely avoidable if patients take medication with a large glass of water and do not lie down shortly after ingesting medication. This is a side effect shared by all tetracycline derivatives which are not recommended for children younger than eight years of age and women during pregnancy. Extended-release minocycline formulations display an adverse event profile similar to placebo. Doxycycline has a long history of safe and effective treatment in acne patients. An early study by Plewig et al 28 evaluated the efficacy of doxycycline in 62 patients in a double-blind crossover study. Statistically, improvement from baseline was significant with doxycycline treatment, but not placebo. In a clinical study by Moore et al, 29 patients were randomized to one of three treatments—a 40mg dose of modified-release doxycycline, a mg dose of doxycycline, or placebo. After 16 weeks of treatment, reduction in lesion count and success rate were evaluated. For both outcome measures, doxycycline treatment was superior to placebo. Interestingly, the lower dose of modified-release doxycycline was more effective in reducing the number of overall lesions, suggesting that a large part of the efficacy of doxycycline stems from its role as an anti-inflammatory agent. A review article that gathered results from tetracycline treatment studies for acne between and showed that doxycycline was consistently effective, although results were variable between studies. Due to the popularity of doxycycline, several brands are available, each boasting additional benefits aside from their efficacy in treating acne. Acticlate is available as a functionally scored tablet, and dosage can be easily modified without requiring a new prescription. Another tetracycline derivative, minocycline, was FDA-approved after doxycycline, in , and continues to be a popular treatment option for moderate to severe acne.
