Doxycycline, a commonly prescribed tetracycline, remains on intermittent shortage. We systematically reviewed the literature to assess minocycline as an alternative to doxycycline in select conditions, given doxycycline's continued shortage. We identified 19 studies, 10 of which were published before 2000. Thirteen of the studies were prospective, but only 1 of these studies was randomized. Based on the available data, we found minocycline to be a reasonable substitute for doxycycline in the following scenarios: skin and soft-tissue infections and outpatient treatment of community-acquired pneumonia in young, otherwise healthy patients or in patients with macrolide-resistant Antibacterial drug shortages are a growing interference in the clinical management of infectious diseases [1–4]. Close to 150 antibacterial agents experienced shortages between 20, with nearly one quarter of these drugs experiencing more than 1 shortage . The impact of a drug shortage is felt at the patient-physician interface and on the institutional level. FDA Status Doxycycline is commercially available as capsule/tablet 20mg, 50mg, 75mg, 100mg, 150mg, delayed release capsule/tablet 40mg, 50mg, 75mg, 100mg, 120mg, 150mg, 200mg, reconstituted solution 100mg, reconstituted suspension 25mg/5ml, oral syrup 50mg/5ml. Doxycycline is a semi-synthetic tetracycline antibiotic, derived from oxytetracycline. It may be used orally (dogs, cats and horses) or intravenously (dogs and cats). Tetracycline antibiotics are broad-spectrum and bacteriostatic. Their mechanism of action is through the inhibition of protein synthesis, and the alteration of cytoplasmic membrane permeability within the susceptible organism. Doxycycline is more lipid-soluble than other tetracycline antibiotics and may reach higher levels in some of the difficult to penetrate areas, such as synovial fluid, central nervous system, prostate, and the eyes. Tetracycline antibiotics, including doxycycline, are effective against a broad spectrum of gram-negative and gram-positive bacteria, and wide variety of other organisms including Rickettsia, Spirochetes, Mycoplasma, Leptospira, Anaplasma, and Chlamydia. In addition to its use as an antibiotic, doxycycline is used in low doses as an anti-inflammatory and adjunct treatment for arthritis and degenerative joint-disease in dogs and horses.

The tetracyclines, including doxycycline, have a similar antimicrobial spectrum of activity against a wide range of gram-positive and. Hello Doctor, A doctor here asked me to take Doxycycline for 7 days and also any broad spectrum drugs, but after taking these drugs, I still have the discharge and it also feels like it didn t work. Apr 28, 2014. A long-acting semisynthetic tetracycline with broad-spectrum antimicrobial properties, doxycycline inhibits protein synthesis through the 30S. Derivatives are crystalline, yellowish, amphoteric substances that, in aqueous solution, form salts with both acids and bases. They characteristically fluoresce when exposed to ultraviolet light. The most common salt form is the hydrochloride, except for hyclate or monohydrate. The tetracyclines are stable as dry powders but not in aqueous solution, particularly at higher p H ranges (7–8.5). Preparations for parenteral administration must be carefully formulated, often in propylene glycol or polyvinyl pyrrolidone with additional dispersing agents, to provide stable solutions. Tetracyclines form poorly soluble chelates with bivalent and trivalent cations, particularly calcium, magnesium, aluminum, and iron. exhibit the greatest liposolubility and better penetration of bacteria such as Staphylococcus aureus than does the group as a whole. Microbiology: The tetracyclines are primarily bacteriostatic and are thought to exert their antimicrobial effect by the inhibition of protein synthesis. The tetracyclines, including doxycycline, have a similar antimicrobial spectrum of activity against a wide range of gram-positive and gram-negative microorganisms. Cross-resistance of these microorganisms to tetracyclines is common. Indications: Doxycycline is indicated for the treatment of the following infections: Because many strains of the following groups of microorganisms have been shown to be resistant to doxycycline, culture and susceptibility testing are recommended. Doxycycline is indicated for treatment of infections caused by the following gram-negative microorganisms, when bacteriologic testing indicates appropriate susceptibility to the drug:--Escherichia coli --Enterobacter aerogenes (formerly Aerobacter aerogenes) --Shigella species --Acinetobacter species (formerly Mima species and Herellea species) --Respiratory tract infections caused by Haemophilus influenzae. --Respiratory tract and urinary tract infections caused by Klebsiella species. Doxycycline is indicated for treatment of infections caused by the following gram-positive microorganisms when bacteriologic testing indicates appropriate susceptibility to the drug:--Upper respiratory infections caused by Streptococcus pneumoniae (formerly Diplococcus pneumoniae).
