INSTRUCTION FOR THE SPECIALIST.

Description of the drug approved by the manufacturer for the printed edition of 2017.

PHARMACHOLOGIC EFFECT

Antibiotic group lincosamides for topical use.

Clindamycin phosphate is inactive in vitro, but it rapidly hydrolyses in vivo to form clindamycin, which has antibacterial activity.

Clindamycin inhibits protein synthesis in a microbial cell due to interaction with the ribosome 50S subunit.

In vitro, the following microorganisms that cause bacterial vaginosis are sensitive to clindamycin: Gardnerella vaginalis, Mobiluncus spp., Mycoplasma hominis, Bacteroides spp., Peptostreptococcus spp.

PHARMACOKINETICS

Suction

After intravaginal application of clindamycin in a dose of 100 mg / day once for 7 days, C max of clindamycin in blood plasma is achieved after 10 h (4-24 h) and is on the 1st day on the average 18 ng / ml (4-47 ng / ml), and on the 7th day - 25 ng / ml (6-61 ng / ml), while the systemic absorption is about 4% (0.6-11%) of the administered dose.

In women with bacterial vaginosis, about 4% of clindamycin (with a smaller spread of 2-8%) undergoes a similar systemic dosing regimen, C max is reached after 14 hours (4-24 hours) after administration and on the first day is on the average 13 ng / ml (6-34 ng / ml), and on the 7th day - 16 ng / ml (7-26 ng / ml).

Systemic exposure to clindamycin for intravaginal application is less pronounced than when administered intravenously or intravenously.

Excretion

T 1/2 is 1.5-2.6 hours. After repeated intravaginal administration, clindamycin is almost not cumulative.

Pharmacokinetics in specific patient groups

In clinical studies of clindamycin, 2% of the vaginal cream involved an inadequate number of patients 65 years of age or older, so that the difference in clinical response to therapy between this age group and younger patients could be assessed.
In the available reports, there was no difference in the response of elderly patients and younger patients from clinical experience.
INDICATIONS

bacterial vaginosis.

DOSING MODE

1 complete applicator (5 g of cream, approximately 100 mg of clindamycin) is inserted into the vagina preferably at bedtime for 3 or 7 consecutive days.

Terms of use

In the package with 20 g of cream there are 3 plastic applicators, and in the package with 40 g - 7 applicators intended for the correct introduction of cream into the vagina.

1. Remove the cap of the tube with cream.
Screw the plastic applicator onto the threaded neck of the tube.
2. While rolling the tube from the opposite end, gently squeeze the cream into the applicator.
The applicator is full when its piston comes to a stop.
3. Unscrew the applicator from the tube and wrap the cap.

4. In the supine position on your back, pull your knees to your chest.

5. Holding the applicator horizontally, you should carefully insert it into the vagina as deeply as possible, without causing unpleasant sensations.

5. Slowly push the piston against the stop, insert the cream into the vagina.

6. Carefully remove the applicator from the vagina and discard it.

SIDE EFFECT

The safety of clindamycin in the form of a vaginal cream was evaluated in both non-pregnant patients and in patients during the II and III trimesters of pregnancy.

CONTRAINDICATIONS

- an antibiotic-associated colitis in the anamnesis;

- age under 18 years (data on safety, efficiency are absent);

- Hypersensitivity to clindamycin, lincomycin or any component of the drug.

PREGNANCY AND LACTATION

Adequate and controlled studies on the use of the drug in the first trimester of pregnancy have not been conducted.
The use of Dalacin in the first trimester of pregnancy is possible only on absolute indications, i.e. if the intended benefit of therapy with the drug for the mother exceeds the potential risk to the fetus.
In studies on animals with the introduction of clindamycin c / o or inside any adverse effects on the fetus is not found, except for cases of taking the drug in doses toxic to the mother.

When clindamycin was administered intravaginally in the II and III trimesters of pregnancy, there was no increase in the frequency of congenital abnormalities of the fetus.
Abnormal births occurred in 1.1% of women compared with 0.5% in the placebo group, if Dalacin ® vaginal cream was used in the II trimester for 7 days. The use of the drug in the II-III trimester of pregnancy is possible if the potential benefit to the mother exceeds the risk to the fetus.
It is not known whether clindamycin is excreted in breast milk after intravaginal application.
Clindamycin is found in breast milk after oral administration or parenteral administration. Therefore, during lactation, you should either abolish the drug or stop breastfeeding, given the importance of the drug for the mother.
APPLICATION FOR CHILDREN

Contraindicated use of the drug in children and adolescents under the age of 18 years (safety data, no efficacy).

APPLICATION IN ELDERLY PATIENTS

In clinical studies of clindamycin, 2% of the vaginal cream involved an inadequate number of patients 65 years of age or older, so that the difference in clinical response to therapy between this age group and younger patients could be assessed.
In the available reports, there was no difference in the response of elderly patients and younger patients from clinical experience.
SPECIAL INSTRUCTIONS

Prior to the appointment of the drug with the help of special laboratory methods, the following possible causative agents of vulvovaginitis should be excluded: Trichomonas vaginalis, Chlamydia trachomatis, Neisseria gonorrhoeae, Candida albicans and Herpes simplex virus.

Intravaginal application of Dalacin can lead to increased growth of insensitive microorganisms, especially yeast-like fungi.

With the use of clindamycin (as well as almost all antibiotics), the development of severe diarrhea and, in some cases, pseudomembranous colitis, is possible internally or intravaginally.
In this regard, if there is a marked or prolonged diarrhea on the background of Dalatine therapy, it is necessary to cancel the drug and, if necessary, to carry out diagnostic and therapeutic measures.
The patient should be informed that, during the use of the vaginal cream, sexual contact should be avoided, as well as the use of other types of products intended for intravaginal administration (eg tampons, douching).

It is not recommended to use Dalacin ® during menstruation.
It is necessary to postpone the initiation of therapy until the end of menstruation.
Dalacin ® contains components that can reduce the strength of products made of latex or rubber (condoms, birth control vaginal diaphragms).
Therefore, the use of such products during treatment with Dalacin and within 72 hours after use is not recommended.
Impact on the ability to drive vehicles and manage mechanisms

There is no reason to believe that the use of the drug may affect the ability to drive and control machinery.

OVERDOSE

With intravaginal application of Dalacin ® cream, clindamycin can be absorbed in amounts sufficient to develop systemic reactions.

Accidental ingestion of the drug in the gastrointestinal tract can also cause systemic effects similar to those that occur after ingestion of clindamycin in therapeutic doses.
Possible systemic side effects include diarrhea, hemorrhagic diarrhea, including pseudomembranous colitis.
Treatment: if necessary, conduct symptomatic and supportive therapy.

DRUG INTERACTION

There is cross-resistance between clindamycin and lincomycin.

In vitro, antagonism between clindamycin and erythromycin has been demonstrated.

It has been established that clindamycin disrupts neuromuscular transmission and, therefore, can enhance the action of muscle relaxants of peripheral action,
so the drug should be used with caution in patients receiving drugs of this group.
Joint use with other drugs for intravaginal administration is not recommended.
