“Accutane” usually makes wonders at the worst form of acne - cystic. The four-monthly course slowly destroys disgusting cysts and nodules, and improvement frequently proceeds also after termination of treatment. For approximately 30 % of the patients a repeated course is necessary. ” Accutane ” is also applied for treatment of persistent extensive papulo-pustular acne.
It is not necessary to use “Accutane” at easy forms of disease such as, drying up and compressing sebaceous glands, it dries up all surface of a body. Almost at each patient accepting it the lips decrepitate, the skin starts to be shelled and scratched, eyes are watering, nasal bleedings and abaissement of hair are sometimes observed. By-effects disappear upon termination of treatment, and the majority of patients agree on such discomfort as the end result surpasses all their expectations.
If any of courses of treatment prescribed by the doctor has not given positive results at nudules and cystic acne then the course of Accutane is prescribed.
This is a strong agent, used for treatment of acne. Usually application of Accutane within 4-5 months leads to remission of an integument of acne. It is a very effective remedy for almost all types of infringements of integument.
Isotretinoin belongs to the class of the medicines named “retinoids”. Accutane is necessary in case of occurrence of very strong implications of acne with cicatrixes and scars, on which other agents do not influence. It is also used for treatment of acne, which are present for many years and are weakly subject to influence of antibiotics in the form of tablets and ointments. Though Accutane has many serious by-effects, in certain respects its use is more safe, than long application of antibiotics. Many other preparations used against acne are anti-infectives, which are effective only at daily application.
Isotretinoin was also used for treatment of other infringements of skin, including keratosis follicularis, pityriasis rubra pilaris, lamellar ichthyosis, keratosis palmaris et plantaris, rosacea and leukoplakia.
Accutane represents natural derivative of vitamin A and can be found out in vascular system of all people. In big doses vitamin A possesses the same effect, as Accutane – both bad, and good. However, it quickly becomes harmful, owing to accumulation in bones (important note: do not accept vitamin A together with Accutane!).
Accutane is formed in an organism, by natural way, from vitamin A, which is present at vascular system. Therefore, big doses of vitamin A accepted at pregnancy, cause the same congenital defects, as Accutane. Fortunately, it is the substance of a natural origin, the organism is capable to deduce quickly Accutane from a blood channel. It is deduced from an organism within 9 days. Accutane “cures” approximately half of people which accept it, therefore, these people never need any other agents against acne.
By-effects
The majority of by-effects of Accutane depend on the dose. As a rule, at appointment of the recommended doses the advantage and risk parity, considering gravity of disease, is comprehensible to the patient.
The symptoms connected with hypervitaminosis A: more often - xeroderma, mucosas of labiums, nasal cavity (bleeding), laryngopharynx (hoarseness of voice), eyes (conjunctivitis, reversible turbidity of cornea and intolerance of contact lenses).
Skin and its appendages: rash, itch, dermatitis of face, sweating, piogenic granuloma, paronychias, onychodystrophy, the strengthened growth of granulation tissue, a proof thinning of hair, reversible abaissement of hair, fulminant forms of acne, hirsutism, hyperpegmentation, photosensitization.
Osteomuscular system: pains in muscles, pains in joints, a hyperostosis and other changes of bones, tendinites. At one patient development of hyperostoses of a backbone and a calcification vertebral ligaments with the subsequent compression of a spinal cord at long (throughout several years) treatment by other preparation of retionoids group is described. Accutane is not intended for long application; however it is necessary to remember about the probability of this by-effect at wrong (too long) application of a preparation.
The central nervous system and mental sphere: behaviour infringements, depression, a headache, rising of intracranial pressure, convulsive attacks.
Sense organs: separate cases of infringements of visual acuity, reduction of acuity of hearing in a certain range of sound waves, photophobia, infringements of adaptation to darkness (reduction of acuteness of twilight sight), cataract, keratitis.
Gastroenteric tract: a nausea, inflammatory diseases of an intestine (colitis, ileitis), bleedings; transitional and reversible rising of activity of transaminases, separate cases of a hepatitis. In many these cases the changes of the norm did not overstep the bounds of norm and came back to initial indicators in the course of treatment, however in some situations there was a necessity to reduce a dose or to cancel Roaccutane.
Breath organs: bronchospasm.
Blood system: reduction of number of leucocytes and erythrocytes, augmentation or reduction of number of thrombocytes, ESR acceleration.
Laboratory changes: hypertriglyceridemia, hypercholesterinemia, hyperuricemia; separate cases of depression of level high-density lipoprotein, especially at appointment of preparation in big dose to predisposed patient (with the family anamnesis burdened by infringement of a fatty exchange, diabetes, adiposity or alcoholism). These changes are also dose-dependent and are normalised after reduction of a dose or cancellation of preparation.
Immune system: local or system infections caused by Gram-positive originators (Staphylococcus aureus).
Other: lymphadenopathy, hematuria, proteinuria, pancreatitis (the risk at patients with hypertriglyceridemia > 800 mg is especially high), vasculitis (Wegener’s granulomatosis).
Safety measures
Accutane should be prescribed only by the doctors, preferably dermatologists, having experience of application of system retinoids and aware about risk teratology at application of Accutane during pregnancy.
It is recommended to supervise function of a liver before treatment, 1 month after its beginning, and then each 3 months. It is necessary to define also level of lipids in serum on an empty stomach (before treatment, 1 month after the beginning and in the end 3-4-months course of treatment).
In rare instances at the patients receiving Accutane, depression, psychotic semiology and suicidal attempts are described. Though their causal relationship with application of preparation is not established, it is necessary to observe extra care at patients with depression in the anamnesis and to observe all patients about occurrence of depression during treatment by a preparation, if necessary referring them to corresponding expert.
Because of possibility of osteal changes it is necessary to prescribe Accutane only at serious forms of disease, carefully estimating a parity of possible advantage and risk and limiting application of preparation only by serious cases of disease.
As acne is an androgen-dependent disease, it is not necessary to apply the contraceptives containing progestinum with androgenic action, for example, derivatives of 19-nortestosteron, especially, if the patient has a gynecologic endocrine pathology.
It is necessary to avoid carrying out of dermabrasion to the patients receiving Accutane, and also within 5-6 months after the termination of treatment because of possibility of the strengthened cicatrisation in atypical places.
During treatment with Accutane and within 5-6 months after it it is impossible to do epilation by means of applications of wax because of risk of development of dermatitis.
The patients from the group of high risk (with diabetes, adiposity, alcoholism or infringements of fatty exchange) at treatment by Accutane may need more frequent laboratory control of corresponding indicators.
At presence of diabetes or suspicion on it more frequent definition of a glycemia is recommended. There are reports on rising of level of glucose in blood on an empty stomach and on cases of disease by diabetes during treatment with Accutane though their causal relationship with reception of preparation is not established.
At patients, who receive or shortly before it (1-2 weeks) received Accutane, it is impossible to take donor blood for transfusion to women of genital age.
