Active ingredients: Clindamycin
Zindaclin? 1% Gel
Why is Zindaclin used? What is it for?
Zindaclin is used in the treatment of mild to moderate acne (pimples). Zindaclin contains an antibiotic (clindamycin) which reduces the number of bacteria, prevents skin pores from clogging and the formation of new pimples. Zindaclin can also help reduce the redness of existing pimples.
Once you start using Zindaclin, it will take some time before you see improvement in your acne.
What is acne?
Acne is an extremely common skin condition, mainly in adolescence but not restricted to this stage of life. During adolescence, the glands in the skin produce excess fat in response to the amount of sex hormones in the body, and this causes the pores to clog, leading to the formation of blackheads. When this happens the pores are invaded by bacteria. The chemicals produced by these bacteria penetrate the deeper layers of the skin and produce red pimples filled with pus.

04.0 CLINICAL INFORMATION
04.1 Therapeutic indications
ZINDACLIN is indicated for the treatment of mild and moderate acne vulgaris.
04.2 Posology and method of administration
Adults and adolescents
Apply a thin layer of ZINDACLIN once a day on the affected area. It is good practice to check the patient's response after 6-8 weeks of treatment. However, the duration of treatment should not exceed 12 weeks.
ZINDACLIN is not indicated for children below 12 years.
ZINDACLIN is contraindicated in patients with hypersensitivity to the active substance clindamycin or to any excipient contained in the medicinal product. Although cross-sensitivity with lincomycin has not been demonstrated, it is recommended not to administer ZINDACLIN to patients who have experienced "hypersensitivity to lincomycin."
04.4 Special warnings and appropriate precautions for use
Oral and parenteral administration of clindamycin, like most antibiotics, has been associated with the onset of severe pseudomembranous colitis. The topical use of clindamycin has been associated only in very rare cases with pseudomembranous colitis; however, if diarrhea occurs, the product must be discontinued immediately.
Studies have shown that the primary cause of antibiotic-dependent colitis is a toxin produced by Clostridium difficile. Colitis is usually characterized by severe and persistent diarrhea and abdominal cramps. In the event that antibiotic-associated colitis occurs, you must immediately proceed with diagnostic tests and the institution of appropriate therapy (eg discontinuation of ZINDACLIN and, if necessary, antibiotic treatment with vancomycin or metronidazole).
The response may appear after 4-6 weeks.
Although the risk of systemic absorption following administration of ZINDACLIN is low, the possible occurrence of adverse effects on the gastrointestinal tract must still be evaluated in the indication of treatment to patients with a history of antibiotic-dependent colitis, enteritis, colitis. ulcerative disease or Crohn's disease.
Prolonged use of clindamycin can lead to the development of resistance and / or cause the growth of non-susceptible bacteria or fungi, although this is rare.
Cross-resistance with other antibiotics such as lincomycin and erythromycin is possible. See section 4.5.
Avoid contact with the eyes or with the mucous membranes of the nose and mouth. In case of accidental contact with the eyes or mucous membranes, rinse the affected area with plenty of fresh water.
ZINDACLIN 1% Gel contains propylene glycol. May cause skin irritation.
The use of occlusive dressing may increase the irritation potential of ZINDACLIN.
04.5 Interactions with other medicinal products and other forms of interaction
In vitro studies have shown antagonism between erythromycin and clindamycin, synergy with metronidazole and both antagonistic and synergistic effects with aminoglycosides.
04.6 Pregnancy and breastfeeding
There are no clinical data on the cutaneous application of clindamycin in pregnancy. Some data relating to a limited number of cases of use of clindamycin in pregnancy administered by other routes do not indicate adverse effects on pregnancy or on the health of the fetus / newborn. From the studies conducted on the animals do not emerge direct or indirect harmful effects on pregnancy, on the development of the embryo / fetus, on parturition or on postnatal development. However, the drug should be prescribed with caution to pregnant women.
The presence of clindamycin in breast milk has been reported following oral or parenteral administration. It is not known whether clindamycin is excreted in breast milk after taking ZINDACLIN. In general, it is a good idea to stop breastfeeding while taking any medicine since many of them are excreted in human milk.
It is therefore advisable to carefully evaluate the benefit / risk ratio in case of administration during pregnancy or breastfeeding. Sensitization and diarrhea phenomena in nursing children cannot be excluded.
04.7 Effects on ability to drive and use machines
04.8 Undesirable effects
About 10% of patients may experience an adverse reaction. These reactions are those characteristic of irritant dermatitis. The incidence may increase if an excessive amount of gel is used. In case of irritation, the use of a moisturizing product may be helpful.
The table below lists all adverse reactions observed with ZINDACLIN in clinical studies. They are listed by frequency, in descending order.
Although no cases of severe diarrhea or pseudomembranous colitis have been reported during clinical trials with ZINDACLIN and the amount of clindamycin absorbed through the skin is minimal, very rare cases of pseudomembranous colitis have been reported associated with the use of other topical products. There is therefore a theoretical risk of developing pseudomembranous colitis following the use of ZINDACLIN (see section 4.4).
Overdose is not expected to occur with normal use. The incidence of adverse reactions typical of irritant dermatitis is increased when excessive amounts of ZINDACLIN were applied. In these cases it may be useful to use a suitable moisturizer. In subsequent applications a thin film of ZINDACLIN should be applied according to the dosage instructions (see section 4.2).
05.0 PHARMACOLOGICAL PROPERTIES
05.1 Pharmacodynamic properties
Pharmacotherapeutic group: Antiinfectives for the treatment of acne
ATC code: D10A F01
ZINDACLIN contains clindamycin phosphate, which is transformed into the active ingredient clindamycin in the skin by hydrolysis. Clindamycin is a lincosamide antibiotic which has mainly "bacteriostatic activity against Gram positive aerobes and a" wide range of anaerobic bacteria.
In the cutaneous administration of clindamycin phosphate, clindamycin is found in the samples of comedones, at concentrations sufficient to exert an activity against most of the strains of Propionibacterium (P. acnes). It therefore reduces the number of superficial and follicular P.acnes , one of the etiological factors of the disease.
As with other antibiotics, prolonged use of clindamycin in the skin can lead to the development of resistance.
05.2 "Pharmacokinetic properties
The ZINDACLIN formulation results in a reduction in systemic absorption of clindamycin. An in vitro study with ZINDACLIN applied to healthy human skin demonstrated that the in vitro absorption of radiolabelled clindamycin phosphate from the ZINDACLIN formulation is less than 5% of the applied dose.
When ZINDACLIN is applied cutaneously in patients with acne, at a dosage of 8 g per day for 5 days, well above the maximum expected clinical dosage, the plasma levels of clindamycin measured were very low (on average less than 2 ng / ml) .
Clindamycin phosphate is metabolised to the parent drug in the skin and clindamycin itself is metabolised primarily in the liver via N-demethylation, sulfoxidation and hydrolysis and essentially excreted in the bile.
05.3 Preclinical safety data
Preclinical data for clindamycin indicate no risk to humans based on conventional studies of safety pharmacology, repeated dose toxicity, genotoxicity or reproductive toxicity.
