Use of Intranasal Oxytocin During Detoxification of Crack Cocaine
Randomized, Double-Blind, Placebo Controlled Study of Intranasal Oxytocin During Detoxification of Crack Cocaine
Randomized treatment control trial, double-blind, parallel, with two arms including ninety-six hospitalized women between 18 and 52 years. Those who agree to participate in the study and meet the eligibility criteria will be randomly allocated to one of the following experimental conditions:
- Conventional oxytocin treatment (T + OC): 32 female cocaine users hospitalized for detoxification will receive six 4 IU jets of intranasal oxytocin twice daily (daily dose of 48 IU) as adjunctive treatment to conventional treatment from the eighth to seventeenth day of hospitalization (duration of oxytocin treatment of 10 days). Conventional treatment includes supportive individual and group psychotherapy (once a week), nutritional control, regular physical activity and psychopharmacotherapy as needed to relieve the symptoms of anxiety, aggression and agitation typical of withdrawal and care. 21 days of hospitalization.
- Conventional treatment with placebo administration (T + PBO): 32 female cocaine users hospitalized for detoxification will receive six jets of placebo solution (2% odor-generating propolis essence + the same vehicle as intra-nasal oxytocin: 0.05% citric acid, 0.9% sodium chloride, 1% glycerol, 0.54% disodium phosphate, 0.2% methylparaben + propylparaben, 1% sorbitol, 80% water) twice daily as adjunctive treatment to conventional treatment from the eighth to the seventeenth day of hospitalization (duration of placebo treatment of 10 days). Conventional treatment includes supportive individual and group psychotherapy (once a week), nutritional control, regular physical activity and psychopharmacotherapy as needed to relieve the symptoms of anxiety, aggression and agitation typical of withdrawal and care. 21 days of hospitalization.
- Conventional treatment (T): 32 female cocaine users hospitalized for detoxification will receive conventional treatment including individual and group supportive psychotherapy (once a week), nutritional control, regular physical activity and psychopharmacotherapy if needed for symptom relief. anxiety, aggression and agitation, typical of abstinence and nursing care, during 21 days of hospitalization.

- Puerperium
- Breastfeeding
- Menopause
- Currently using hormone therapy
- Total hysterectomy
- Diagnosis or suspicion of autoimmune or neurological diseases and / or syndromes (stroke, Parkinson and Alzheimer's)

- HIV +
Primary Outcome Measure:
- Withdrawal symptoms Change from baseline withdrawal symptoms (hospital admission) at the end of detoxification treatment (21 days) assessed by Cocaine Selective Severity Assessment (CSSA, minimum and maximum scores: 0 - 112). After treatment, the oxytocin-treated group is expected to have significantly lower withdrawal scores (better outcome) than the other groups (30%).
- Anxiety symptoms Change from baseline anxiety symptoms (hospital admission) at the end of detoxification treatment (21 days) assessed by the Patient-Reported Outcomes Measurement Information System Short Form scale (PROMIS, minimum and maximum raw scores: 8 - 40). After treatment, the oxytocin-treated group is expected to show lower anxiety scores (better outcome) compared to the other groups (30%).
- Depression symptoms Change from baseline depressive symptoms (hospital admission) at the end of detoxification treatment (21 days) assessed by the Quick Inventory of Depressive Symptomatology Self-Report scale (QIDS-SR, minimum and maximum scores: 0 - 27). After treatment, the oxytocin-treated group is expected to show lower depressive scores (better outcome) compared to the other groups (30%).
Secondary Outcome Measures:
- Neuroleptic Dose Change Dose change of neuroleptic medications used during hospitalization for agitation or irritability (expected 25% lower).
- Adherence of outpatient treatment Rate of adherence of outpatient treatment six months after discharge (expected to be 20% higher) assessed by reviewing the medical records of each patient within the outpatient program. If patient would be enrolled in the outpatient program after six months from detoxification she will be considered adhered to the program (higher rates means better outcome).
