Published Studies Related to Inderal (Propranolol)

The study of antiarrhythmic medications in infancy (SAMIS): a multicenter, randomized controlled trial comparing the efficacy and safety of digoxin versus propranolol for prophylaxis of supraventricular tachycardia in infants. [2012]
CONCLUSIONS: There was no difference in SVT recurrence in infants treated with

Status of propranolol for treatment of infantile hemangioma and description of a randomized clinical trial. [2011.10]
OBJECTIVES: Our primary objective was to review the current use of propranolol for treatment of infantile hemangioma (IH), specifically regarding 1) the age at initiation of therapy, 2) the method of initiation, 3) the use of other adjuvant therapy, 4) the duration of therapy and relapse rate, 5) the adverse events, and 6) the outcome. Our secondary objective was to describe a randomized, controlled, single-blinded trial comparing propranolol to prednisolone for treatment of IH... CONCLUSIONS: Propranolol is an attractive alternative to other treatments for IH. Despite apparent widespread use of this medication, the data are limited, and prospective studies are lacking for this indication. The relatively high rate of adverse effects supports the need for careful monitoring of patients on this therapy. Fastidious reporting of adverse events and objective evaluation of early and late outcomes are necessary to improve our understanding of the use of propranolol for this indication.

A randomized controlled trial of propranolol for infantile hemangiomas. [2011.08]
OBJECTIVE: Propranolol hydrochloride is a safe and effective medication for treating infantile hemangiomas (IHs), with decreases in IH volume, color, and elevation... CONCLUSION: Propranolol hydrochloride administered orally at 2 mg/kg per day reduced the volume, color, and elevation of focal and segmental IH in infants younger than 6 months and children up to 5 years of age.

Endoscopic variceal band ligation compared with propranolol for prophylaxis of first variceal bleeding. [2011.04]
Administration of nonselective beta-blockers in prophylaxis of first variceal bleeding is not suitable for all patients. Thus, we evaluated endoscopic variceal band ligation (EVBL) in primary prevention of bleeding in patients with cirrhosis and large esophageal varices... In conclusion, EVBL was an effective and safe alternative to propranolol in primary prophylaxis of bleeding in patients with large esophageal varices.

Effect of propranolol on word fluency in autism. [2011.03]
OBJECTIVE AND BACKGROUND: Autism is characterized by repetitive behaviors and impaired socialization and communication. Preliminary evidence showed possible language benefits in autism from the beta-adrenergic antagonist propranolol. Earlier studies in other populations suggested propranolol might benefit performance on tasks involving a search of semantic and associative networks under certain conditions. Therefore, we wished to determine whether this benefit of propranolol includes an effect on semantic fluency in autism... CONCLUSIONS: Results are consistent with a selective beneficial effect of propranolol on flexibility of access to semantic and associative networks in autism, with no observed effect on phonological networks. Further study will be necessary to understand potential clinical implications of this finding.

Clinical Trials Related to Inderal (Propranolol)

Propanolol and Red Cell Adhesion Non-asthmatic Children Sickle Cell Disease [Recruiting]
Propanolol is a beta blocker which has been found to inhibit the ability of epinephrine to upregulate sickle red cell adhesion to laminin and endothelial cells in vitro. The purpose of this pilot study is to administer one dose of propanolol to children with sickle cell disease and to measure pre and post dose red cell adhesion. The hypothesis is that a single dose of propanolol will decrease red cell adhesion to laminin and endothelial cells as compared to baseline.

Efficacy of Propranolol Treatment to Prevent Melanoma Progression [Not yet recruiting]
Melanoma's incidence is increasing worldwide. The efforts made in melanoma screening led to an earlier detection of the primary tumour and a better prognosis, but melanoma remains an aggressive cancer when it comes to its metastatic stage. Three recent retrospective studies compared groups of patients diagnosed with primary melanoma and treated with betablockers for another indication to patients who never received betablockers. In these three studies, the outcome of the disease is significantly better for people under betablocker treatment with a decreased rate of recurrence and a better 5 years survival rate. Here we want to investigate the efficacy and the tolerability of an adjuvant treatment with propranolol for patients suffering from a primary melanoma with a high risk of recurrence.

Propranolol Treatment of Traumatic Memories (PTTM) [Recruiting]
This study will compare the responses of subjects with traumatic memories of varying vintages to either propranolol or placebo in a double-blind setting. It is hypothesized that those subjects who receive propranolol will experience less emotional distress when the memory is subsequently reactivated and less spontaneous re-experiences.

Perioperative Propranolol in Patients With Post Traumatic Stress Disorder (PTSD) [Recruiting]
Understanding what treatments may facilitate perioperative care of Veterans with posttraumatic stress disorder (PTSD) is of great importance to the U. S. health care system. Patients with PTSD are characterized by elevated central nervous system catecholamine concentrations and exaggerated and prolonged adrenergic responses to stress stimuli. At present, there are no data on the effects of perioperative beta blocker therapy in patients with PTSD, despite the rising significance of PTSD in Veteran populations. This prospective, double-blind study proposes to randomize 150 Veterans with PTSD scheduled for orthopedic, thoracic or vascular surgery at the San Francisco VA Medical Center to either a 14-day course of propranolol or placebo. This study will then follow these Veterans for a one-year period to evaluate the effects of the intervention on Veterans' surgical outcomes. The investigators hypothesize that patients with PTSD randomized to the propranolol group will demonstrate a reduced incidence of perioperative and postoperative morbidity and mortality.

Corticosteroids With Placebo Versus Corticosteroids With Propranolol Treatment of Infantile Hemangiomas (IH) [Terminated]
This is a prospective randomized, double-blind study to compare the clinical efficacy of infantile hemangioma treatment using propranolol with corticosteroids as compared to therapy with corticosteroids and placebo. We hypothesize that a two-month treatment period with propranolol plus corticosteroids is more effective at reducing infantile hemangioma size and vascularity when compared to corticosteroids used without propranolol for the same time period.

Inderal review by 30 year old male patient

Overall rating:  
Effectiveness:   Highly Effective
Side effects:   No Side Effects
Treatment Info
Condition / reason:   situational anxiety
Dosage & duration:   40mg daily as needed taken few times per month for the period of past 6 years
Other conditions:   none
Other drugs taken:   none
Reported Results
Benefits:   I've used 40mg Inderal for situational anxiety a few times per month over the past 6 years. I found it to be very effective when taken 30min to 1hr prior to public speaking, large social gatherings, dates, and other anxiety provoking situations. It really helps decrease signs of nervousness resulting from the fight-or-flight response, such as increased heart rate, sweaty palms, and dry mouth.
Side effects:   none
Comments:   as above


Inderal review by 23 year old female patient

Overall rating:  
Effectiveness:   Highly Effective
Side effects:   No Side Effects
Treatment Info
Condition / reason:   Severe Performance Anxiety
Dosage & duration:   1.5 mg taken single dose a year for the period of 3 years
Other conditions:   None
Other drugs taken:   None
Reported Results
Benefits:   Miracle drug for anyone who's deathly afraid of giving speeches or oral presentations. Eliminates the whole butterflies-in-the-stomach feeling, racing heart, sweaty palms and allows you to focus on what your doing and do it properly rather than worry about how nervous you are.
Side effects:   None.
Comments:   The doc first suggested that I take paxil every day for 3 wks before a speech and then get off it. I had to push her to prescribe me Inderal instead because I had researched all the drugs extensively and new what I was looking for. Never rely entirely on the judgement of doctors, always verify their advice and do your own research. It can save you time, money and alot of side effects. I take 3 small tablets and hour before a major speech or presentation (about once a year). I am thinking about using it for situational anxiety as another user suggested, I had never thought about it as I try to stay as far from drugs as possible and I only use them in extreme situations, but I have missed many networking opportunities because of my anxiety and I think that this drug would have helped. I have not experienced any side-effects. I don't think the drug has significantly risky long-term effects. I think the long-term negative effects of situational anxiety are far worse then the potential risks of inderal.


Inderal review by 31 year old female patient
