(isotretinoin capsules)

Isotretinoin, a retinoid, is available as Accutane in 10-mg, 20-mg and 40-mg soft gelatin capsules for oral administration.

Accutane is indicated for the treatment of severe recalcitrant nodular acne. Nodules are inflammatory lesions with a diameter of 5 mm or greater. The nodules may become suppurative or hemorrhagic. "Severe," by definition,2 means "many" as opposed to "few or several" nodules. Because of significant adverse effects associated with its use, Accutane should be reserved for patients with severe nodular acne who are unresponsive to conventional therapy, including systemic antibiotics. In addition, Accutane is indicated only for those females who are not pregnant, because Accutane can cause severe birth defects (see boxed CONTRAINDICATIONS AND WARNINGS).

A single course of therapy for 15 to 20 weeks has been shown to result in complete and prolonged remission of disease in many patients. 1,3,4 If a second course of therapy is needed, it should not be initiated until at least 8 weeks after completion of the first course, because experience has shown that patients may continue to improve while off Accutane. The optimal interval before retreatment has not been defined for patients who have not completed skeletal growth (see WARNINGS: Skeletal: Bone Mineral Density, Hyperostosis, and Premature Epiphyseal Closure).

Mortality in the randomized, controlled lung intergroup trial of isotretinoin. [2010.06]
In 2001, we reported that mortality may have been higher with isotretinoin (30 mg/d for 3 years) than with placebo in the subgroup of current smokers among the 1,166 patients with definitively resected early-stage non-small cell lung cancer who participated in the randomized, controlled Lung Intergroup Trial...

A randomized and controlled trial about the use of oral isotretinoin for photoaging. [2010.02]
Topical retinoids are used to treat photoaging; oral isotretinoin is gold standard for acne; "off label" indications, including photoaging, have been reported with insufficient evidence of efficacy. This is a randomized controlled phase II trial with clinical and histological assessment to evaluate efficacy and safety of oral isotretinoin for photoaging...

Clinical Trials Related to Accutane (Isotretinoin)

Efficacy and Safety of Low-dose Oral Isotretinoin for Seborrhea [Recruiting]
Oral isotretinoin is the gold standard drug to treat moderate to severe acne. Other indications like seborrhea, seborrheic dermatitis have been suggested. There is risk of reversible mucocutaneous side effects, as well as alterations in lipid profile and transaminases. The major problem is teratogenicity which demands pregnancy control from treatment beginning to one month after treatment end. Seborrhea and seborrheic dermatitis are chronic conditions characterized by oily skin, hair and scalp, erythema, desquamation and negative impact on quality of life. This will be an interventional, therapeutic and quality of life randomized, comparative (parallel groups), blinded evaluation clinical trial, comprising 50 men and women, aged 18 to 40. Treatment with low-dose oral isotretinoin will be compared to topical anti-seborrheic products to evaluate the reduction of sebaceous secretion and colonization of affected areas by yeasts of Malassezia gender. Efficacy will be evaluated by clinical parameters, as well as by sebum secretion measure and application of quality of life questionnaires. Safety will be evaluated by skin hydration measure, side effects report and observation. For subjects using oral isotretinoin blood counting, transaminases, lipid profile and pregnancy test will be requested as selection criteria, on days 30 and 180. Data will be submitted to statistical analysis.

Aflac ST1001 Prolonged Isotretinoin [Recruiting]
Neuroblastoma is a cancer of the nervous system and accounts for 15% of cancer related deaths in children. With the advancement of treatment therapies, the long term survival rate has progressed to approximately 50%. The therapy used for treatment, however, is very toxic and associated with serious long-term side effects. Treatment for neuroblastoma typically includes chemotherapy, surgery, stem cell transplantation, radiation therapy, and immunotherapy. At the end of this treatment, children with neuroblastoma commonly take the drug isotretinoin for 6 months. Isotretinoin maintains the response to previous treatments and helps turn the remaining cancer cells into normal nerve cells.

Most patients often respond to this treatment at first but are at a high-risk for the cancer coming back. The majority of the children who relapse after treatment or develop recurrent disease do so in the first two years following the completion of therapy and there are no current treatments to cure those who relapse. This study will explore whether or not extending the therapy with isotretinoin from 6 months to 24 months will help prevent the cancer from coming back without causing severe side effects.

Erlotinib Hydrochloride and Isotretinoin in Treating Patients With Recurrent Malignant Glioma [Recruiting]
RATIONALE: Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Isotretinoin may help cells that are involved in the body's immune response to work better. Giving erlotinib hydrochloride together with isotretinoin may kill more tumor cells.

PURPOSE: This phase I trial is studying the side effects and best dose of erlotinib hydrochloride when given with isotretinoin in treating patients with recurrent malignant glioma.

Vorinostat and Isotretinoin in Treating Patients With High-Risk Refractory or Recurrent Neuroblastoma [Recruiting]
This phase I trial is studying the side effects and the best dose of vorinostat when given together with isotretinoin to see how well it works in treating patients with high-risk refractory or recurrent neuroblastoma. Vorinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Isotretinoin may help vorinostat work better by making tumor cells more sensitive to the drug. Giving vorinostat together with isotretinoin may be an effective treatment for neuroblastoma

Identifying the Genetic Predictors of Severe Acne Vulgaris and the Outcome of Oral Isotretinoin Treatment [Recruiting]
The goal of this study is to enroll 250 participants that have joined the MURDOCK Study Horizon 1. 5 (Duke IRB Pro00011196) with a current or prior diagnosis of severe acne AND current or prior treatment with oral isotretinoin. All 250 participants will answer a 5-page questionnaire designed to collect information on the diagnosis of severe acne and response to oral isotretinoin treatment. The aim is to identify genetic predictors of severe acne vulgaris and the outcome of oral isotretinoin treatment.

Accutane review by 43 year old female patient

Overall rating:  
Effectiveness:   Highly Effective
Side effects:   Mild Side Effects
Treatment Info
Condition / reason:   acne
Dosage & duration:   40mg daily taken 20 mg 2xday for the period of 4 months
Other conditions:   none
Other drugs taken:   none
Reported Results
Benefits:   Permanently: cured of cystic acne. Temporarily: eliminated blackheads, smoothed skin texture, skin appeared "poreless".
Side effects:   Dry skin and lips, increased susceptibility to developing blisters on feet if walking long distances without careful attention to socks and shoes. Stupidly used "Biore" skin strips early in the treatment to speed up removal of the blackheads and pulled all the skin off my nose.
Comments:   I am 43 now but took Accutane back in my early 20's for moderate cyctic acne. I took a second course in my 30's for mild/moderate non-cystic acne which was probably hormone related. I absolutely loved taking Accutane and wished that I could take it again at a milder dosage to treat blackheads and have that smooth "poreless" skin again. It seems to speed up skin cell sloughing and I didn't need to exfoliate, just use a good cream. After years of taking antibiotics and using awful creams that made my skin dry and red, Accutane was a godsend. My older brother and sister have terrible deep scars from cystic acne (my sister had dermabrasion many years ago before the age of laser) but I do not have one scar from my cyctic acne.

Benefits:   Completely eliminated my acne while I was on the drug, however acne did return once I stopped, though not as bad.
Side effects:   Dry skin, which was easily taken care of with a moisturizer. Dry lips. I didn't experience any of the other side effects often mentioned such as depression.
Comments:   I would take 2x20mg pills daily. I needed to moisturize my face once a day also. When i began I weaned myself onto the drug -- take 20mg for the first week before stepping upto the 40mg dose.
