Published Studies Related to Retin-A (Tretinoin Topical)

Tretinoin cyclodextrin complex (RA/CyD) causes less irritation with an equal antiwrinkle effect compared with conventional tretinoin: clinical and histologic studies of photoaged skin. [2012]
the side effects compared with RA treatment alone... CONCLUSION: The findings show that RA and RA/CyD result in the equivalent

A randomized, double-blind, placebo-controlled, pilot study to assess the efficacy and safety of clindamycin 1.2% and tretinoin 0.025% combination gel for the treatment of acne rosacea over 12 weeks. [2012]
rosacea after 12 weeks of usage... CONCLUSIONS: A combination gel of clindamycin phosphate 1.2% and tretinoin 0.025%

A randomized, double-blind, controlled comparative trial of the anti-aging properties of non-prescription tri-retinol 1.1% vs. prescription tretinoin 0.025%. [2012]
Vitamin A and its derivatives (commonly termed retinoids) are widely used in topical anti-aging products. Certain retinoids such as retinol and its esters are available without a prescription, while others such as tretinoin are available only via prescription... Subjects reported >93 percent overall satisfaction with both products at weeks 8 and 12.

Retinoic acid reduces chemotherapy-induced neuropathy in an animal model and patients with lung cancer. [2011.09.06]
OBJECTIVE: To evaluate the effect of all-trans retinoic acid (ATRA) as treatment for chemotherapy-induced peripheral neuropathy in an experimental animal model and in a randomized, double-blinded, controlled trial in patients with non-small-cell lung cancer (NSCLC)... CONCLUSIONS: ATRA reduced chemotherapy-induced experimental neuropathy, increased NGF levels, and induced RAR-beta expression in nerve. In patients, reduction of NGF in serum was associated with the severity of neuropathy; ATRA treatment reduced the electrophysiologic alterations. Classification of evidence: This study provides Class II evidence that ATRA improves nerve conduction in patients with chemotherapy-induced peripheral neuropathy.

Further enhancement of facial appearance with a hydroquinone skin care system plus tretinoin in patients previously treated with botulinum toxin Type A. [2011.07]
BACKGROUND: A hydroquinone (HQ) skin care system has been designed for use in conjunction with nonsurgical procedures. OBJECTIVE: The authors evaluate the efficacy of this system plus tretinoin for improving facial appearance in comparison to a standard skin care regimen in users of botulinum toxin Type A (BoNT-A)... CONCLUSIONS: Adjunctive use of the HQ system plus tretinoin can further enhance the improvements in facial appearance attained with BoNT-A. Applying the HQ system plus tretinoin offers multiple clinical benefits over standard skin care, including significantly greater improvements in fine lines/wrinkles and hyperpigmentation.

Clinical Trials Related to Retin-A (Tretinoin Topical)

Combined Tretinoin and Arsenic Trioxide for Patients With Newly Diagnosed Acute Promyelocytic Leukemia Followed by Risk-Adapted Postremission Therapy [Recruiting]
The purpose of this study is to find what effects, good and/or bad, treatment with two drugs has on leukemia. The first medicine is tretinoin (also called all-trans retinoic acid, ATRA, or Vesanoid). It is an approved medicine that causes the leukemia cells in APL to mature. It is related to vitamin A. The second is arsenic trioxide (Trisenox). It is an approved medicine for APL that comes back after earlier treatment.

APL is most often treated with tretinoin and standard chemotherapy drugs. These chemotherapy drugs can cause infection and bleeding. They can also damage the heart and normal bone marrow cells. This can lead to a second leukemia years later.

In this study, the investigators are using tretinoin and arsenic trioxide together. Both drugs work to treat APL. They have been used together in only a limited number of people. The investigators want to use these drugs together to reduce the amount of standard chemotherapy and decrease side effects. The patient will receive standard chemotherapy with a drug called idarubicin only if they have a higher chance of the leukemia coming back or a higher risk of side effects.

Comparison of Retinol 1.0% and Tretinoin 0.02% in the Treatment of Moderate to Severe Photodamage and Wrinkles [Recruiting]
The purpose of this study is to assess the comparative efficacy of retinol 1. 0% and tretinoin 0. 02% in minimizing wrinkles, discoloration, roughness, and other signs of moderate to severe photodamage. Our hypothesis is that both products will be of comparable benefit.

A Study Comparing Combination Clindamycin Phosphate/Tretinoin Gel Alone Versus With Benzoyl Peroxide Foaming Cloths for Facial Acne [Recruiting]
There are many different factors that cause acne. So combination treatment using different medications that can address these different factors is commonly used to treat acne. Fixed-dose combination clindamycin phosphate 1. 2% and tretinoin 0. 025% gel and benzoyl peroxide 6% foaming cloths are both used to treat acne. This study will evaluate the use of the medications when used together.

A Comparative Study of Adapalene Gel,0.3% Versus Tretinoin Emollient Cream, 0.05% for the Treatment of Photoaging [Recruiting]
The purpose of this study is to:

1. Evaluate the efficacy of Adapalene gel 0. 3% compared to Tretinoin Emollient cream 0. 05%, reducing signs of cutaneous photoageing, measured trough photonumeric scale evaluation, investigator evaluation of global response to treatment and subject's evaluation of improvement.

2. Evaluate the safety and tolerability of Adapalene Gel 0. 3%, compared to Tretinoin Emollient cream 0. 05% during 24 weeks of treatment.

The study has the clinical hypothesis that Adapalene Gel 0. 3% is as effective as Tretinoin Emollient cream 0. 05% in the treatment of cutaneous photoaging.

Atralin Gel for the Treatment of Rosacea [Recruiting]
Erythematotelangiectatic rosacea is a type of rosacea that causes a red face often with frequent flushing, topical sensitivity and prominent blood vessels. We think that long term damage to skin from the sun (photodamage) may play a role in causing this type of rosacea. Tretinoin is a topical medication that is known to improve photodamage. We want to find out if Atralin (tretinoin 0. 05%) Gel used for up to 46 weeks will improve erythematotelangiectatic rosacea (ETR).

Retin-A review by 24 year old female patient

Overall rating:  
Effectiveness:   Highly Effective
Side effects:   Mild Side Effects
Treatment Info
Condition / reason:   minor acne
Dosage & duration:   .01 (dosage frequency: every day) for the period of a year
Other conditions:   dry skin
Other drugs taken:   none
Reported Results
Benefits:   My skin stopped breaking out as often and became much softer and smoother. The color really improved as well - much less blotchy and more "dewy."
Side effects:   Very dry skin. A lot of peeling.
Comments:   After washing my face with a gentle cleanser, I would wait 20 minutes and then put on the cream. I would then wait another 20 minutes and put some lotion on because the tretnoin was just too drying.


Retin-A review by 28 year old male patient

Overall rating:  
Effectiveness:   Moderately Effective
Side effects:   Moderate Side Effects
Treatment Info
Condition / reason:   Acne
Dosage & duration:   0.01% (dosage frequency: once a day) for the period of 2 years
Other conditions:   none
Other drugs taken:   none
Reported Results
Benefits:   Reduced acne. I had mild/moderate acne, and Retin-A did decrease the amount of ance I had. I liked Retin-A also because it reduces wrinkles. I am only 28, so I don't have many wrinkles, but used it as prevention.
Side effects:   My skin would become too dry. It seemed that even after months of usage, my ance would not completely disappear. If I used more Retin-A, my acne would get better for a week or two until my skin became too dry and then I would have worse acne
Comments:   I would apply Retin-A to my face once a day at night

Other drugs taken:   Antibiotics for acne
Reported Results
Benefits:   Occasionally, acne would subside slightly.
Side effects:   Excessively dry skin and irritation
Comments:   I was to apply the Retin-A cream twice a day but the side effects outweighed any effects of treatment.
