Clinical Trials Related to Risperdal (Risperidone)

Risperdal Consta for Bipolar Disorder [Active, not recruiting]
We are recruiting 50 consenting adult subjects with DSM-IV TR diagnoses of bipolar disorder who are about to initiate or switch their current antipsychotic agent. Patients are titrated and cross-tapered during a 3 month titration and stabilization phase. Presently 4 of the 11 subjects enrolled have transitioned successfully and are in Phase III of the study. After transitioning into the next phase, they will be followed for an additional 12 months. Clinical outcomes such as study drop out, adverse events, worsening of symptoms, crisis interventions, need for additional medication, hospitalizations etc. will be evaluated from months 3 to 15 (visits 8-20). The time to clinical events will be used to evaluate if the long acting injectable form of risperidone has an advantage over the oral second generation antipsychotic agents in terms of treatment continuity and clinical stability.

Schizophrenia Risperidone vs Olanzapine Study HGMN [Completed]
Summary of Study Design This is a randomized, double-blind, flexible-dosed, parallel study exploring the relationship between early response to an antipsychotic medication and subsequent improvement in psychopathology using the atypical antipsychotic risperidone, and determining if patients who do not show an early response to risperidone can achieve an adequate improvement in clinical status following 10 weeks of treatment with olanzapine.

Risperdal review by 30 year old female patient

  Rating
Overall rating:  
Effectiveness:   Considerably Effective
Side effects:   Moderate Side Effects
  
Treatment Info
Condition / reason:   Anxiety
Dosage & duration:   1 mg a day and as needed taken every day for the period of for 3+ years-currently, various doses
Other conditions:   bipolar disorder, add, hypothyroid
Other drugs taken:   Lamictal, Neurontin, Strattera, Levothyroid, Klonopin
  
Reported Results
Benefits:   In the case of a panic attack, this would soothe the anxiety and calm me down-a numbing sensation--a highly effective anti-psychotic in several situations--kept a low-level feeling of calmness and barrier to anxiety/stress
Side effects:   Unfortunately, weight gain was a marked side effect, and led me to take a lower dose--also in high doses, I almost felt like a zombie--totally numb and emotionless--a disturbing concept.
Comments:   Prescribed by my psychiatrist to use in various doses over several years of use to use for anxiety and panic, and in conjunction with Klonopin as an effective measure to reduce a mixed/manic episode of bipolar disorder in an acute situation, and also at a low-level dose every day to reduce the chance of episodes from occuring. Good tool in anger management as well.

Comments:   The treatment plan was realy bad. Although i had gone from crazy back to normal again over an 8 day period i was then made to take the drug for another 9 and a half months there after. This drug should be used as needed e.g taken to stop being crazy, and then stopped once patient has returned to normal state NOT any longer! I was basicly druged up to the eye balls an lost almost a year of my life.

Side effects:   memory loss, heart diseasse, increased panick attacks, curbed thinking, loss of sex drive, increased paranoia, increased suicidal thoughts, increase in depression, anxiety. Decreased mental capacities.
Comments:   I was put on 3.5 mg of this damned drug.
