Effect of doxycycline vs placebo on retinal function and diabetic retinopathy
progression in mild to moderate nonproliferative diabetic retinopathy: a
randomized proof-of-concept clinical trial. 
IMPORTANCE: Microglia have been associated with inflammatory changes underlying
diabetic retinopathy. OBJECTIVE: To investigate whether low-dose oral doxycycline monohydrate, a drug
capable of inhibiting microglial activation, can improve or slow the
deterioration of retinal function and whether it can induce regression or slow
progression of diabetic retinopathy in patients with mild to moderate
nonproliferative diabetic retinopathy (NPDR)...

Clinical studies on the management of periodontal diseases utilizing subantimicrobial dose doxycycline (SDD). [2011.02]
Periodontitis, the most common chronic inflammatory condition known to mankind, is a disease that results in the destruction of tooth supporting tissues. Periodontitis is initiated by a bacterial biofilm on the tooth surface below the gingival margin... This review paper begins with a brief description of the disease process known as periodontitis followed by an extensive review of the Phase I-IV clinical trial data that established the safety and efficacy of sub-antimicrobial dose doxycycline (SDD) as an adjunct to scaling and root planing for the treatment of periodontitis.
Clinical Trials Related to Periostat (Doxycycline Hyclate)
NGU: Doxycycline (Plus or Minus Tinidazole) Versus Azithromycin (Plus or Minus Tinidazole) [Completed]
This study will look at the safety, effectiveness, and tolerability of combination
medications for the initial treatment of non-gonococcal urethritis (NGU). NGU is
inflammation of the tube that carries urine from the bladder. NGU is caused by bacteria that
may be passed from person to person during sex. This study will compare the 2 currently
recommended NGU treatments, doxycycline and azithromycin, taken with tinidazole (another
medication to treat certain sexually transmitted infections). Tinidazole used with
doxycycline or azithromycin may cure NGU better than when doxycycline or azithromycin is
used alone. Study participants will be 300 men ages 16-45 years with NGU attending sexually
transmitted disease clinics in Birmingham, AL; New Orleans, LA; Durham, NC; and Baltimore,
MD. Study participation will last 7 weeks and involve 3 visits. At each visit, participants
will provide a urine sample, have 2 urethral swabs, and have their urethra checked for
discharge indicating infection.
Examination of the Anti-inflammatory and Insulin Sensitizing Properties of Doxycycline in Humans [Completed]
Obesity is a heightened state of inflammation in which production of cytokines and matrix
metalloproteinases (MMPs) result in loss of function of insulin receptors and insulin
resistance. Doxycycline (DOX) is a potent MMP inhibitor. We hypothesize that DOX will
enhance insulin sensitivity and decreases inflammation in obese participants with type 2
Trial of the Use of Doxycycline After Rotator Cuff Repair [Not yet recruiting]
The purpose of this study is to examine healing after rotator cuff repair in subjects either
treated with Doxycycline or placebo post-operatively.
Doxycycline Treatment to Prevent Progressive Coronary Artery Dilation in Children With Kawasaki Disease [Not yet recruiting]
Kawasaki disease (KD) affects infants and young children causing inflammation of the skin
and blood vessels including the coronary arteries of the heart. Despite the currently
available therapy, about one third of children develop enlargement of the coronary arteries
that can lead to serious complications such as coronary artery stenosis, heart attack and
Kawasaki disease is the most common heart disease in children in the USA and it is
especially common among the children of Hawaii. Every year, 50-90 children are diagnosed
with KD in Hawaii and unfortunately there is no medication available to successfully prevent
coronary artery damage in a subset of cases.
During the first few weeks of the illness, cells of the immune system attack the coronary
arteries and release a special substance (MMP) that is responsible for the coronary artery
enlargement. There is a common antibiotic, doxycycline that can specifically block the
action of this special substance (MMP). Research done on animals with KD showed that
doxycycline was able to block this special substance and prevent enlargement of coronary
arteries. Research in adults with enlargement of the main artery in their abdomen also
showed that doxycycline may improve the outcome. Based on these studies doxycycline may be a
promising therapy for children with KD, who develop enlargement of the coronary arteries.
The investigators' proposed research study will assess the usefulness of doxycycline in
preventing the progressive enlargement of coronary arteries in children with KD. The
investigators plan to perform a small (pilot) study to evaluate how good is doxycycline in
preventing coronary artery enlargement. The investigators will treat 25 children with KD and
enlarged coronary arteries for two weeks with doxycycline and assess the change in coronary
arteries as well as the blood levels of the special substance (MMP). If doxycycline proves
to be beneficial in this small study, the investigators are going to design a large research
study involving multiple institutions on Hawaii and the mainland and will recruit more
children to be certain about the value of the proposed treatment. The investigators'
proposal may change the treatment protocol of KD and could present a possible treatment for
children with enlarged coronary arteries preventing potentially devastating consequences.
Combining Doxycycline With Bone-Targeted Therapy in Patients With Metastatic Breast Cancer [Active, not recruiting]
The purpose of this study is to see if women with bone metastases from breast cancer will
benefit from the addition of doxycycline to their standard bone-targeted therapy.
Participants will be asked to take 100 mg of Doxycycline orally twice a day for 12 weeks.
Blood and tissue collection will further define the mechanism of the benefits if there are

Periostat review by 56 year old female patient
|Overall rating:|| || |
|Effectiveness:|| || Considerably Effective|
|Side effects:|| || Moderate Side Effects|
|Condition / reason:|| || Rosacea|
|Dosage & duration:|| || 100 mg taken once a day for the period of 3 years|
|Other conditions:|| || None|
|Other drugs taken:|| || None|
|Benefits:|| || The drug prevents the pustules that can result from Rosacea. When I do not take the drug for a week, the pustules tend to reappear.|
|Side effects:|| || When I first started the drug, I felt nauseated for a few days. It gradually subsided. It helped to take the drug with food, although I initially was told to take it 2 hours after eating. Now I can tolerate it better, but still must take it at about the same time every day or it bothers my stomach and I get nauseated.|
|Comments:|| || My Rosacea had progressed to the second stage (pustules) before I was diagnosed. I woke up one morning with pustules on my face, and one was infected. I went immediately to a dermatologist, who diagnosed me with Rosacea and prescribed 200 mg of doxycycline daily. I tried that, but my stomach would not tolerate it. He lowered the dose to 100 mg, and I did better, although it took a few days to adjust.|
