Conditions: Fibromyalgia
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 9
Healthy volunteers: no

Brief summary:
We have found that low dose naltrexone (LDN) can substantially reduce pain associated with fibromyalgia syndrome. We believe LDN may work via novel anti-inflammatory channels. The purpose of this study is to determine if LDN lowers inflammatory markers in individuals with fibromyalgia.

Detailed description:
Eligible women with Fibromyalgia (FM) will be enrolled into a 10-week drug trial. During the first two weeks, a baseline phase will be used to collect data on immune function and symptoms. LDN will be administered for 8 weeks. Although there is no placebo arm built-in, participants will be advised that they may receive a placebo during the trial. Participants will provide twice daily symptom reports using an android tablet device and Dooblo SurveyToGo survey software. Participants will also provide a blood sample twice every week for the duration of the study. Plasma inflammatory markers will be tested using a luminex based 63-plex inflammatory assay panel.

The primary aim of the study is to test if 8 weeks of LDN administration is associated with a reduction in pro-inflammatory markers in plasma in women with FM.

Arms:
arm 1: Following a two-week baseline the study drug was administered daily for 8 weeks. Participants were informed that placebo or LDN would be provided during the drug period and that all participants would receive LDN at some point during the study. In fact, all participants received the active LDN (4.5 mg nocte) throughout the drug-administration period.

Interventions: intervention 1: Low Dose Naltrexone
Intervention descriptions: intervention 1: Naltrexone 4.5 mg p.o. nocte
