Nabilone is a synthetic cannabinoid that has shown promise for the treatment of posttraumatic stress disorder (PTSD)–related insomnia and nightmares as well as efficacy in the management of chronic pain. It has also been proposed for harm reduction in cannabis dependence. Its effectiveness for management of concurrent disorders in seriously mentally ill correctional populations has not been evaluated. This retrospective study of 104 male inmates with serious mental illness prescribed nabilone analyzes the indications, efficacy, and safety of its use. Medications discontinued with the initiation of nabilone were also reviewed. The results showed nabilone targeting a mean of 3.5 indications per patient, thus likely reducing polypharmacy risk. The mean final dosage was 4.0 mg. Results indicated significant improvement in PTSD-associated insomnia, nightmares, PTSD symptoms, and Global Assessment of Functioning and subjective improvement in chronic pain. Medications associated with greater risk for adverse effects or abuse than nabilone were often able to be discontinued with the initiation of nabilone, most often antipsychotics and sedative/hypnotics. There was no evidence of abuse within this high-risk population or reduction of efficacy when nabilone was given in powder form with water rather than as a capsule. This study supports the promise of nabilone as a safe, effective treatment for concurrent disorders in seriously mentally ill correctional populations. Prospective, randomized controlled trials are required to confirm our preliminary results. Follow-up in the community will be required to confirm effectiveness in harm reduction.

The clinical and hormonal response to 12-month therapy with the antiandrogen, spironolactone, in conjunction with near-physiologic doses of female gonadal steroids in 50 transsexual males, is presented. An unselected referred series of 61 men with the psychiatric diagnosis of transsexualism was treated; 10 subjects who had received previous gonadal surgery and 1 man with Klinefelter's syndrome were excluded. Twenty-seven conventionally treated (CT; high-dose estrogen), age 34.4 +/- 10.5 years, mean +/- SD, and 23 untreated patients (SPS), age 30.7 +/- 6.2 years, were studied. Following the initial visit, all 50 were begun on spironolactone and low-dose female hormone therapy. Despite high-dose estrogen treatment for more than 2 years, the mean testosterone (T) level for the CT group was not in the female range (169 +/- 193 ng/dl; normal 20-80). Spironolactone, in doses of 200-600 mg/day, lowered T to the female range in both groups after 12 months (CT 87 +/- 111 and SPS 49 +/- 41 ng/dl). This was achieved in the CT group despite decreases in estrogen dose and discontinuation of parenteral therapy. SPS subjects experienced significant decreases in plasma T (642 +/- 236 to 49 +/- 41 ng/dl, p less than 0.001). Systolic blood pressure dropped (128 +/- 14 to 121 +/- 14 mm Hg, p less than 0.05). The clinical response, including decreased male pattern hair, breast development, feminization, and lack of erections was excellent in most subjects.
