Minocycline is a broad-spectrum tetracycline antibiotic, and has a broader spectrum than the other members of the group. It is a bacteriostatic antibiotic, classified as a long-acting type. As a result of its long half-life, it generally has serum levels two to four times that of the simple water-soluble tetracyclines. Minocycline is the most lipid-soluble of the tetracycline-class antibiotics, giving it the greatest penetration into the prostate and brain, but also the greatest amount of central nervous system-related side effects, such as vertigo. Uncommon side effects (with prolonged therapy) include skin discolouration and autoimmune disorders that are not seen with other drugs in the class. Minocycline is a relatively poor tetracycline-class antibiotic choice for urinary pathogens sensitive to this antibiotic class, as its solubility in water and levels in the urine are less than all other tetracyclines. Minocycline is metabolized by the liver and has poor urinary excretion. Minocycline was patented in 1961 and came into commercial use in 1971. Doxycycline is used to treat infections caused by bacteria, including pneumonia and other respiratory tract infections; certain infections of the skin or eye; infections of the lymphatic, intestinal, genital, and urinary systems; and certain other infections that are spread by ticks, lice, mites, infected animals, or contaminated food and water. It is also used along with other medications to treat acne. Doxycycline is also used to treat or prevent anthrax (a serious infection that may be spread on purpose as part of a bioterror attack), in people who may have been exposed to anthrax in the air, and to treat plague and tuleramia (serious infections that may be spread on purpose as part of a bioterror attack). Doxycycline can also be used in people who cannot be treated with penicillin to treat certain types of food poisoning. Doxycycline (Oracea) is used only to treat pimples and bumps caused by rosacea (a skin disease that causes redness, flushing, and pimples on the face). Doxycycline is in a class of medications called tetracycline antibiotics. It works to treat infections by preventing the growth and spread of bacteria.

Kelly Smith, MD1; and JamesJ. Leyden, MD 2. 1 Warner Chilcott Laboratories, Rockaway, New. —Dotevall and Hagberg  from Göteborg University (Göteborg, Sweden) deserve praise for their well-done study on oral doxycycline treatment of Lyme disease—associated facial palsy and meningitis. This study confirms that oral doxycycline is equivalent to parenteral ceftriaxone in the treatment of Lyme disease—associated palsy and/or meningitis. Experience indicates 21 days of oral doxycycline therapy is equivalent to 14 days of ceftriaxone therapy , and Swedish investigators have demonstrated that equivalent results are achieved with doxycycline therapy for ≤2 weeks (median, 10.8 days). Dotevall and Hagberg correctly point out that there has been some reluctance to use oral antibiotics in the treatment of Lyme neuroborreliosis because of fear of inadequate CSF and/or CNS penetration [2, 3]. Doxycycline is preferred over conventional tetracycline for this purpose because of its lipid solubility characteristics [4–6], as stated by Dotevall and Hagberg. Doxycycline is 5 times more lipid soluble than conventional tetracycline, which is an important determinant of permeability of the blood-brain barrier [7, 8]. Dotevall and Hagberg showed that most patients had highly elevated CSF protein levels, which is the best index of antibiotic permeability of the blood-brain barrier. Is a semisynthetic, second‐generation tetracycline derivative which crosses the blood–brain barrier and may inhibit microglial‐related inflammatory events and also the apoptotic cascade. Several studies have shown that is neuroprotective in animal models of central nervous system trauma and neurodegenerative diseases; in particular, this compound has greatly enhanced survival in nigrostriatal dopaminergic neurons in the MPTP model of PD (). A study of doxycycline, another anti-inflammatory mediator in the tetracycline derivative family, also observed reductions in alcohol consumption in mice, along with increased sensitivity to the motor-impairing effects of alcohol ( for acne 100 mg PO BID for 2 years. He presented to his physician with joint pain, fatigue, weight loss and blue fingers on exposure to the cold. He also experienced pain and a palpable firm mass in his left testis. After immunologic testing, his anti-neutrophil cytoplasmic antibody (ANCA) was positive at 0 titre and antinuclear antibody (ANA) showed positivity on Hep2 cells. was stopped due to these findings and the patient was given prednisone in combination with hydroxychloroquine 400 mg PO daily.

Safety of Doxycycline and Minocycline A. -. What Is the Difference between Minocycline and. Minocycline is even more highly lipid soluble than doxycycline and has excellent CSF penetration making it potentially useful in treating Lyme neuroborreliosis. Minocycline is 2 times more lipid soluble than doxycycline, thereby making it a potential alternative for Dec 27, 2018. Thirty-two heartworm-positive dogs were randomized to receive 10 mg/kg or 5 mg/kg of either doxycycline or minocycline for 28 days BID, for a. Doxycycline vs Minocycline for Acne.
