CISTIDIL ® is an L-Cystine based drug
THERAPEUTIC GROUP: Other dermatological preparations
Indications CISTIDIL ® L-cystine
CISTIDIL® is used as an adjuvant in the treatment of acne, atrophic dermatitis and psoriasis.
Mechanism of action CISTIDIL ® L-cystine
CISTIDIL ® is a drug based on L-Cystine, an extremely important amino acid from a biological point of view given the numerous patterns in which it falls.
The appropriate intake of this amino acid, especially in clinical conditions characterized by a significant increase in its requirement, would ensure:
- the correct synthesis of taurine and therefore of bile salts, fundamental in the hepatic detoxification processes;
- the appropriate synthesis of glutathione, one of the main cellular endogenous antioxidants;
- the correct synthesis of keratin, an important protein for the correct structuring of skin appendages such as nails, hair and hair;
- the correct synthesis of molecular mediators such as immunoglobulins and hormones fundamental in preserving the functioning of the organism.
All the aforementioned biological actions are adjuvant by excellent pharmacokinetic properties that allow the amino acid taken per os to be rapidly absorbed in the intestine by active transport and subsequently poured into the portal blood and made available for the various biological functions.
Studies carried out and clinical efficacy
CYSTINE IN THE PREVENTION OF DOXORUBICIN ALOPECIA
Arch Dermatol Res. 2013 Jan; 305: 25-34. doi: 10.1007 / s00403-012-1253-1. Epub 2012 Jun 15.
Chemoprevention of doxorubicin-induced alopecia in mice by dietary administration of L-cystine and vitamin B6.
D "Agostini F, Fiallo P, Ghio M, De Flora S.
Very interesting experimental study that demonstrates the efficacy of the combination of L-Cystine and vitamin B6 in counteracting alopecia induced by drugs such as doxorubicin, particularly aggressive chemotherapy drugs.
