Pharmacological Actions of Isotretinoina Valeant

Isotretinoina Valeant is the first generation of tretinoin, which is a stereoisomer of all-trans tretinoin. It has anti-greasy influence when taken by mouth, in addition to has unique alleviative result on severe acne. The system of task is as follow:
① It has the functions of minimizing gland, impeding the task of gland, and also minimizing the secretion of gland, for that reason preventing the leisure of Propionibacterium acnes that trusts the development of lipid environment.
② It has anti-keratosis, hinders method too much advancement of skin cells as well as advertises their difference, as well as can decrease keratinization of hair origins orifice as well as sebaceous air duct.
③ It can in addition affect the attribute of monocytes along with lymphocytes, avoid the chemotaxis of neutrophils and additionally have anti-inflammatory task.
④ Precisely bind to retinoic acid nuclear receptors to play a corrective duty. Quits the dispersing of Brevi Corynebacterium acnes, has immunostimulatory result at reduced does, as well as immunosuppressive result at high does.
⑤ It can impede the development of collagenase and also gelatinase in the skin, and can hinder the task of ornithine decarboxylase. Since the induction of ornithine decarboxylase can play a considerable function in skin anomalies, isotretinoin can also prevent tumorigenesis.
⑥ When used in your area, the system of activity of this product appears like that of tretinoin, which can trigger epidermal cell proliferation, advertise the differentiation of epidermal granule layer right into stratum corneum, as well as take care of the horny plug in the uncommon process of pilosebaceous epithelial keratinization, so regarding play a corrective function.

Clinical Treatment of Isotretinoina Valeant Dermatology

Acne is a chronic inflammation of hair roots and sebaceous glands, which mainly takes place during puberty and also influences the appearance of the skin. The actual etiology is not very clear, and it may be related to raised secretion of secretory glands, hyperkeratosis of hair roots, uncommon plants as well as swelling. Isotretinoina Valeant can hinder the proliferation of keratinocytes, stop keratin blood clot, prevent sebaceous gland secretion and sebum manufacturing, and also make acne lesions decrease. It can inhibit the secretion of sebum, boost the conversion of thick epithelial cells, as well as turn around unusual keratinization., leading to a reduction in the cohesion of keratinocytes, loosening up and after that naturally eliminating acne, which has a substantial effect on the treatment of acne and has actually become the front runner for acne treatment. Isotretinoina Valeant can control cell spreading, distinction as well as apoptosis in the epidermis, has anti-proliferation, repair work as well as exfoliation results, and also has anti-inflammatory and also immune law results.

Palmoplantar keratosis
The most significant feature of palmoplantar keratoderma is the proportion, diffuse keratosis, and also hypertrophy in the hands as well as soles of the feet. Most of them start from babies, as well as the skin is pale yellow due to hyperkeratosis. General individuals are typically accompanied by hyperhidrosis. Because of keratinization and hypertrophy, chapping is prone to take place in winter season, and also one of the most severe type is mutilated palmoplantar keratoderma. Due to severe keratosis, hypertrophy as well as proliferation, the foot is deformed and also handicapped. Isotretinoina Valeant can bidirectionally regulate the development, differentiation and repair work of epithelial cells as well as other cells, and also normalize the process of keratinization and also distinction; it can normalize the circulation of Langerhans in the skin, and has a straight governing result on the body immune system; Can reduce the movement of neutrophils from the dermis to the skin and also change the attachment in between target cells.

Seborrheic dermatitis
The clinical manifestations of seborrheic dermatitis are scalp itching, oily scales and papules of numerous sizes, and the papules are covered with greasy ranges or scabs, consisting of greasy scalp on the top of the head, modern soft, sporadic hair, and raised shedding. The etiology of seborrheic dermatitis is not totally clear. A lot of research studies think that there is too much seborrhea, accompanied by inflammation second to irregular keratinization of the epithelium of the hair roots orifice. Isotretinoina Valeant prevents the activity of sebaceous glands, reduces sebum secretion, boosts unusual keratinization of epithelial cells, and also has anti-inflammatory effects.

Psoriasis vulgaris
It is normally believed that the mechanism of Isotretinoina Valeant in dealing with psoriasis is: 1. It can stabilize the hyperkeratotic epidermis of psoriasis as well as manage the expansion as well as distinction of the lesioned skin; 2. Trigger macrophages and epidermal Langerhans cells to adjust the sore 3. Decrease the task of polyamine synthetase, to make sure that the biochemical metabolic procedure in the body returns to normal; 4. Prevent keratinocytes, and prevent the DNA and also RNA of epidermal keratinocytes with overactive growth in patients with psoriasis Synthesis, inhibition of vascular endothelial development element, development of cell bond molecules in people.

Main cutaneous amyloidosis
Main cutaneous amyloidosis is an usual metabolic disorder skin disease. Its pathogenesis is not fully recognized, and also it is generally believed to be connected to genes, metabolic problems and also immune responses. Isotretinoina Valeant can manage the mitosis of epidermal cells, hinder the production of keratin, as well as restore the expansion and differentiation of lesioned skin to regular.

Adverse Reactions of Isotretinoina Valeant and How to Deal With Them

1. Acne exacerbation: Temporary exacerbation of acne may occur in the first month of treatment, especially in patients with severe disease, significant acne may require adjustment of treatment. For mild acne, no treatment adjustment is necessary.

2. Skin and mucous membranes: Dry skin and mucous membranes are common during treatment. Especially cheilitis. This can be done with a generous amount of topical emollient, such as petroleum jelly or another lip moisturizer.

Patients with crusted or dry nasal cavity or epistaxis may choose to use saline nasal spray and petroleum jelly to smear the nostrils to improve symptoms. Artificial tears may help relieve symptoms of dry eyes. Try not to wear contact lenses while taking this medicine.

Patients should take sun protection measures to reduce the effects of Isotretinoina Valeant-induced photosensitivity. Patients should use sunscreen with a sun protection factor (SPF) of at least 30 daily and wear protective clothing during sun exposure. Sunscreen should be applied to exposed skin areas before sun exposure and reapplied every two to three hours.

3. Myalgia: Although checking creatine kinase (CK) levels is not recommended in the absence of severe muscle pain, approximately 15% to 50% of patients with isotretinoin-induced myalgia have elevated CK levels. Mild to moderate pain can usually be controlled with anti-inflammatory drugs. Isotretinoin should be discontinued if pain becomes severe or does not improve with anti-inflammatory medications.

4. Laboratory abnormalities—Hypertriglyceridemia, elevated liver transaminases, and elevated CK are common laboratory abnormalities during isotretinoin treatment.

① Hypertriglyceridemia:

Mildly or moderately elevated triglyceride levels (300 to 500 mg/dL) do not require changes in isotretinoin dosage and can be managed with lifestyle changes.

Triglyceride levels between 500 and 800 mg/dL require additional intervention, such as reducing the dose of isotretinoin and/or adding lipid-lowering agents.

Severe hypertriglyceridemia (eg, above 800 mg/dL) may require discontinuation of isotretinoin treatment

② Elevated liver transaminases:

Mild, transient elevations in liver transaminases occur early in treatment in approximately 15% to 20% of patients; levels usually return to normal within a few weeks. If liver transaminase levels reach more than three times normal, it is recommended to discontinue Isotretinoina Valeant

③ Pregnancy:

Despite efforts to minimize the risk of pregnancy during treatment with Isotretinoina Valeant, isotretinoin should be discontinued immediately if pregnancy occurs during treatment. Pregnant patients should be referred for management and counseling to an obstetrician experienced in reproductive toxicity.


Management of other extracutaneous adverse reactions of isotretinoin (eg, psychoactive effects, severe ocular symptoms) may require consultation with appropriate specialists to determine the best course of action for the individual patient.

Patients with signs and symptoms suggestive of pseudotumor cerebri (eg, headache with new-onset vision changes) require specialist evaluation and Isotretinoina Valeant should be discontinued.
