Acne is one of the most common dermatological problem globally. It is a disease of aesthetic concern, as it affects teenagers and young adults very commonly, resulting in both physical and psychological traumas. It is a chronic disease of the skin and is difficult to treat due to its multi-etiological origin. Genetics is the major cause of acne, other equally important factors being the environment, diseases of other organs and systems, hormonal imbalance, and stress.

Scientific Studies on isotretinoin

When it comes to treating acne, isotretinoin has revolutionized the therapy of one of the biggest problems in dermatology. It has also been shown to be quite useful in the treatment of rosacea. As noted in the clinical study by Watson KD et al. “Isotretinoin For Acne and Rosacea” that in last 30 years, clinicians have gained better insight into dosing of isotretinoin, thus preventing reoccurrences of acne and decreasing dose-related adverse events. There was controversy over mood disorders and inflammatory bowel disease being caused by isotretinoin, but latest research has disapproved these claims. With proper knowledge of possible adverse effects and teratogenicity, clinicians can help the patients to get best out of treatment [4].

During last four decades, dermatologists have tried various dosing strategies for isotretinoin to get optimal clinical results with minimum side effects. Standard dose for isotretinoin is 0.5 to 1mg/kg/day. In the clinical trial carried out by Dhaked DR et al. “A Randomized Comparative Trial of Two Low-Dose Oral Isotretinoin Regimens in Moderate to Severe Acne Vulgaris” author studied the clinical efficacy and tolerability of 20 mg dose regimen when given daily and intermittently. 240 patients took part in the study, and they were divided into two groups. First group was given 20mg isotretinoin on a daily basis, while the second group was given every alternate day. Therapy was continued for 24 weeks and had 12 weeks of the follow-up period. At the end of the trial, both groups responded well to the therapy with more than 90% showing acne remission. Though alternate day therapy was better tolerated than daily regimen, it was less effective in cases of severe acne. Hence author of the clinical trial concluded that patients with moderate acne may be given 20 mg isotretinoin on every alternative day, while severe cases need a daily dose of the drug [5].

Treatment of acne often involves prescription of long-term antibiotic therapy. In the review “Optimizing Non-Antibiotic Treatments for Patients with Acne: A Review,” Canavan TN et al. recommend not to prescribe monotherapy of antibiotics and also discourages long-term prescription of antibiotics as resistant to them have become very common. In the review, it is strongly recommended to use non-antibiotic regimens for treatment and maintenance therapy [6].

The economical aspect of medical treatment is often neglected in clinical studies, but in practical remains one of the important non-pharmacological factors in any treatment. In one of the meta-analyses called “The Cost-Effectiveness of Isotretinoin in the Treatment of Acne. Part 1. A Meta-Analysis of Effectiveness Literature” Wessels F et al. studied all the literature and trials published since 1981 to find out the cost-effective treatment of acne. In the study is was noted that isotretinoin is highly effective both regarding the cost of treatment and clinical efficacy and was also well tolerated. Meta-analysis showed the cure rate of above 84% while relapse rate of around 20%. Optimal effect was achieved with a cumulative dose of above 120mg/kg [7].

Dyslipidemias and elevation of hepatic transaminases have been commonly reported in treatment with isotretinoin. But most of the clinical trials reporting these events had small sample size. In the study carried out by Zane LT et al. “A Population-Based Analysis of Laboratory Abnormalities During Isotretinoin Therapy for Acne Vulgaris” large sample size was used. The study involved more than 13000 patients aged 13 to 50 years. In the study, it was found that there was a cumulative increase of 44% in triglycerides from baseline levels, 31% for cholesterol, and 11% for transaminases. Abnormalities in hematological tests were uncommon and unrelated to the therapy. It was also noted that these changes in biochemical tests were transient and reversible [8].

Description and Mechanism of Action of Isotretinoin

Isotretinoin belongs to the retinoids family of drugs and is similar in structure to vitamin A. It has complex and poorly understood the mechanism of action. Isotretinoin is known to suppress excretion of sebum and prevent follicular keratinization, it also has the indirect effect of suppressing P. acnes bacteria. It is also believed to suppress prostaglandin E2 and collagenase, which results in the anti-inflammatory effect of the drug. All these effects together result in suppression of acne.

Customer Reviews

Isotane Testimonial

Another customer from New Zealand who has been on Isotane for 49 days, was quite happy and impressed by the results of product and she wrote in her comments “I’m on day 49 for Isotane and my acne is clearing really well. I do have red marks left over from the previous acne, but it’s slowly fading away, and my skin looks way better than it was 49 days ago. I’ve heard that once you finish Accutane, the red marks disappear pretty quickly and for the shallow scars, its best to avoid using harsh cleansers and lotions as creams and peels for scars tend to be pretty harsh on the skin…”

Conclusion and Rating

No doubt, Isotretinoin is the drug of choice for moderate to severe cases of acne. During four decades of clinical experience with the use of isotretinoin, one can say that though some side effects are quite common with this molecule benefits far outweigh those discomforts.

It has to be understood that acne is caused by various factors, so a person suffering from them requires different and individualized treatment approach. It is always wise to try with topical creams and short-term oral antibiotics If one fails to get the desired result than better to start isotretinoin.

There are several dosage strategies. One strategy is to take low doses like 10 or 20 mg daily for a longer period of time, and another strategy is to start with a dose of 0.5 to 1mg/kg/day. It has been shown in clinical trials that if the user wants full remission without relapse than he/she should take it for a longer period of time, 4 months at least for most cases. In some cases, one may be prescribed for a shorter period of time.

Taking into view the fact that isotretinoin is the most efficient treatment of acne till date and most side effects with the product are transient and reversible, the product can be given the rating of 4 on the scale of 1-5.
