ISOTRETINOIN Accutane or Roaccutane 25MG PER ML X 30ML
Isotretinoin, also known as 13-cis-retinoic acid (and colloquially referred to by its former brand name Accutane or Roaccutane), is a medication primarily used to treat severe acne. Rarely, it is also used to prevent certain skin cancers (squamous-cell carcinoma), and in the treatment of other cancers. It is used to treat harlequin-type ichthyosis, a usually lethal skin disease, and lamellar ichthyosis. It is a retinoid, meaning it is related to vitamin A, and is found in small quantities naturally in the body. Its isomer, tretinoin, is also an acne drug.
Isotretinoin is primarily used as a treatment for severe acne. The most common adverse effects are a transient worsening of acne (lasting 1?4 months), dry lips (cheilitis), dry and fragile skin, and an increased susceptibility to sunburn. Uncommon and rare side effects include muscle aches and pains (myalgias), and headaches. Isotretinoin is known to cause birth defects due to in-utero exposure because of the molecule’s close resemblance to retinoic acid, a natural vitamin A derivative which controls normal embryonic development. It is also associated with psychiatric side effects, most commonly depression but also, more rarely, psychosis and unusual behaviours. Other rare side effects include hyperostosis, and premature epiphyseal closure, have been reported to be persistent.
In the United States, a special procedure is required to obtain the pharmaceutical. In most other countries, a consent form is required which explains these risks. Women taking isotretinoin must not get pregnant during and for 1 month after the discontinuation of isotretinoin therapy. Sexual abstinence or effective contraception is mandatory during this period. Barrier methods by themselves (e.g., condoms) are not considered adequate due to the unacceptable failure rates of approximately 3%. Women who become pregnant while taking isotretinoin therapy are generally counseled to have an abortion.
It was patented in 1969 and approved for medical use in 1982. It sold well for many years, but in 2009, Roche decided to discontinue manufacturing due to diminishing market share due to the availability of the many generic versions of the drug and in the setting of multiple lawsuits over side effects. It continues to be manufactured worldwide in 2019 as Absorica, Amnesteem, Claravis, Myorisan, Sotret, and Zenatane.
Isotretinoin is used primarily for severe cystic acne and acne that has not responded to other treatments. Many dermatologists also support its use for treatment of lesser degrees of acne that prove resistant to other treatments, or that produce physical or psychological scarring. Isotretinoin is not indicated for treatment of prepubertal acne and is not recommended in children less than 12 years of age.
It is also somewhat effective for hidradenitis suppurativa and some cases of severe rosacea. It can also be used to help treat harlequin ichthyosis, lamellar ichthyosis and is used in xeroderma pigmentosum cases to relieve keratoses. Isotretinoin has been used to treat the extremely rare condition fibrodysplasia ossificans progressiva. It is also used for treatment of neuroblastoma, a form of nerve cancer.
Isotretinoin therapy has furthermore proven effective against genital warts in experimental use, but is rarely used for this indication as there are more effective treatments. Isotretinoin may represent an efficacious and safe alternative systemic form of therapy for recalcitrant condylomata acuminata (RCA) of the cervix. In most countries this therapy is currently unapproved and only used if other therapies failed.
Isotretinoin is a teratogen; there is about a 20?35% risk for congenital defects in infants exposed to the drug in utero, and about 30-60% of children exposed to isotretinoin prenatally have been reported to show neurocognitive impairment. Because of this, there are strict controls on prescribing isotretinoin to women who may become pregnant and women who become pregnant while taking isotretinoin are strongly advised to terminate their pregnancies.
In most countries, isotretinoin can only be prescribed by dermatologists or specialist physicians; some countries also allow limited prescription by general practitioners and family doctors. In the United Kingdom and Australia, isotretinoin may be prescribed only by or under the supervision of a consultant dermatologist. Because severe cystic acne has the potential to cause permanent scarring over a short period, restrictions on its more immediate availability have proved contentious. In New Zealand, isotretinoin can be prescribed by any doctor but subsidised only when prescribed by a vocationally-registered general practitioner, dermatologist or nurse practitioner.
In the United States, since March 2006 the dispensing of isotretinoin is run through a website called iPLEDGE. The FDA required the companies marketing the drug in the US, which at the time that iPLEDGE was launched were Roche, Mylan, Barr, and Ranbaxy, to put this website in place as a risk evaluation and mitigation strategy. These companies formed a group called the Isotretinoin Products Manufacturing Group, and it hired Covance to run the website. Prescribers, pharmacists, and all people to whom the drug is prescribed need to register on the site and log information into it. Women with child-bearing potential must commit to using two forms of effective contraception simultaneously for the duration of isotretinoin therapy and for a month immediately preceding and a month immediately following therapy. Additionally they must have two negative pregnancy tests 30 days apart and have negative pregnancy tests before each prescription is written.
Increasingly higher dosages will result in higher toxicity, resembling vitamin A toxicity. Adverse effects include:
