Clindax-B
Clindax-B Uses, Dosage, Side Effects, Food Interaction and all others data.
Clindamycin is a semi-synthetic derivative of lincomycin. It inhibits bacterial protein synthesis by reversibly binding to the 50S ribosomal subunits thus blocking the transpeptidation or translocation reactions of susceptible organisms.
Benzoyl peroxide has mild keratolytic effect and antimicrobial activity which is attributed to its potent oxidizing activity. Clindamycin and Benzoyl peroxide are both active against Propionibacterium acnes, an organism associated with acne vulgaris.

How Clindax-B works
Acne vulgaris is caused by inflammation in the pilosebaceous gland. Acne is generally caused by increased excretion of sebum from pilosebaceous glands, endocrine factors such as androgenic hormones, keratin developing around follicles, bacterial growth, and inflammation. These factors contribute to the formation of comedones (whiteheads and blackheads).
The peroxide bond of benzoyl peroxide is cleaved to form 2 benzoyloxy radicals. These radicals interact nonspecifically with bacterial proteins, interfering with their function, and survival of the bacteria. Over time, free radical interactions with bacterial proteins lead to decreased keratin and sebum around follicles.
Benzoyl peroxide can also increase the turnover rate of epithelial cells, leading to skin peeling, and breaking down comedones.
Clindamycin inhibits bacterial protein synthesis by binding to 23S RNA of the 50S subunit of the bacterial ribosome. It impedes both the assembly of the ribosome and the translation process. The molecular mechanism through which this occurs is thought to be due to clindamycin's three-dimensional structure, which closely resembles the 3'-ends of L-Pro-Met-tRNA and deacylated-tRNA during the peptide elongation cycle - in acting as a structural analog of these tRNA molecules, clindamycin impairs peptide chain initiation and may stimulate dissociation of peptidyl-tRNA from bacterial ribosomes.
The mechanism through which topical clindamycin treats acne vulgaris is unclear, but may be related to its activity against Propionibacterium acnes, a bacteria that has been associated with acne.
Dosage
Clindax-B dosage
Apply to the affected areas once or twice daily (morning and evening) after the skin is gently washed and patted dry.
Refer to individual product recommendations. Some combination products require reconstitution at the time of dispensing by dissolving the Clindamycin powder with purified water, add the solution to the Benzoyl peroxide gel provided and stir until the gel appears homogenous.
Side Effects
Application site pain, Application site exfoliation, Application site irritation, Erythema, Burning, Pruritus, Sunburn, Scaling, Drynes, Colitis, Peelin.
Toxicity
Data regarding overdoses of benzoyl peroxide are not readily available. During an overdose patients may experience and increased risk or severity of adverse effects such as skin itching, burning, peeling, inflammation, and erythema.
The oral LD50 in rats is 490 mg/kg.
The oral LD50 in mice and rats is 2540 mg/kg and 2190 mg/kg, respectively.
While no cases of overdose have been reported, symptoms are expected to be consistent with the adverse effect profile of clindamycin and may therefore include abdominal pain, nausea, vomiting, and diarrhea. During clinical trials, one 3-year-old child was given a dose of 100 mg/kg daily for 5 days and showed only mild abdominal pain and diarrhea. Activated charcoal may be of value to remove unabsorbed drug, but hemodialysis and peritoneal dialysis are ineffective. General supportive measures are recommended in cases of clindamycin overdose.
Precaution
Avoid contact with mouth, eyes, lips & mucous membranes; abraded or eczematous skin. May discolor hair & dyed fabrics. Pregnancy & lactation.
Interaction
May enhance the action of neuromuscular blocking agents (e.g. atracurium). May antagonise the effects of parasympathomimetics. May competitively inhibit the effects of macrolides, ketolides, streptogramins, linezolid and chloramphenicol. Increased coagulation tests (prothrombin time/INR) and/or bleeding with vit K antagonists (e.g. warfarin, acenocoumarol, fluindione). PABA sunscreens may transiently discolour fabric.
Volume of Distribution
Clindamycin is widely distributed in the body, including into bone, but does not distribute into cerebrospinal fluid. The volume of distribution has been variably estimated between 43-74 L.
Elimination Route
In a sample of excised skin, 1.9% of a radiolabelled topical dose fully penetrates the skin, and 2.6% remains in the skin. The radiolabelled dose that fully penetrates the skin is recovered as benzoic acid, while the dose in the skin is approximately half benzoic acid and half benzoyl peroxide. 95.5% of a radiolabelled dose is not absorbed or metabolized after 8 hours.
Oral bioavailability is nearly complete, at approximately 90%, and peak serum concentrations (Cmax) of, on average, 2.50 µg/mL are reached at 0.75 hours (Tmax). The AUC following an orally administered dose of 300mg was found to be approximately 11 µg•hr/mL. Systemic exposure from the administration of vaginal suppository formulations is 40-fold to 50-fold lower than that observed following parenteral administration and the Cmax observed following administration of vaginal cream formulations was 0.1% of that observed following parenteral administration.
Half Life
The elimination half-life of clindamycin is about 3 hours in adults and 2.5 hours in children. Half-life is increased to approximately 4 hours in the elderly.
Clearance
The plasma clearance of clindamycin is estimated to be 12.3-17.4 L/h, and is reduced in patients with cirrhosis and altered in those with anemia.
Elimination Route
Benzoyl peroxide's metabolite benzoic acid, is eliminated in the urine. Data regarding fecal elimination is not readily available.
Approximately 10% of clindamycin bioactivity is excreted in the urine and 3.6% in the feces, with the remainder excreted as inactive metabolites.
Pregnancy & Breastfeeding use
Pregnancy Category- C. Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks
Lactation: Excretion in milk is unknown/ not recommended
Contraindication
Hypersensitivity to Clindamycin, lincomycin, benzoyl peroxide, or any component of the formulation; history of regional enteritis, ulcerative colitis, pseudomembranous colitis or antibiotic-associated colitis.
Acute Overdose
Benzoyl Peroxide gel is a preparation indicated for topical treatment only. If the medication is applied excessively, no more rapid or better results will be obtained and severe irritation might develop. In this event, treatment must be discontinued and appropriate symptomatic therapy should be instituted.
Overdosage with orally administered clindamycin has been rare. Adverse reactions similar to those seen with normal doses can be expected, however, unexpected reactions could occur. Haemodialysis and peritoneal dialysis are not effective in removing clindamycin from the serum. Overdosage should be treated with simple gastric lavage. No specific antidote is known.
Storage Condition
Store in a cool and dry place, protected from light.
Store between 20-25°C. Do not refrigerate or freeze.
