Austaclin-t
Austaclin-t Uses, Dosage, Side Effects, Food Interaction and all others data.
Austaclin-t is a lincosamide antibiotic used in the treatment of infections caused by susceptible microorganisms. Austaclin-t is a semisynthetic antibiotic derived from lincomycin. It has antiacne and antibacterial activity. It binds with the 50s subunit of the bacterial ribosome and inhibits the early stage of protein synthesis. It is highly potent against gram positive and anaerobic bacteria.
Microbiology: Aerobic gram-positive cocci, including: Staphylococcus aureus, Staphylococcus epidermidis (penicillinase and non-penicillinase producing strains), Streptococci, Pneumococci. Anaerobic gram-negative bacilli, including: Bacteroides species, Fusobacterium species. Anaerobic gram-positive non-spore forming bacilli, including: Propionibacterium species, Eubacterium species, Actinomyces species. Anaerobic and microaerophilic gram-positive cocci, including: Peptococcus species, Peptostreptococcus species, Microaerophilic streptococci, C. perfringes
Austaclin-t exerts its bacteriostatic effect via inhibition of microbial protein synthesis. Austaclin-t has a relatively short Tmax and half-life necessitating administration every six hours to ensure adequate antibiotic concentrations.
Clostridium difficile associated diarrhea (CDAD) has been observed in patients using clindamycin, ranging in severity from mild diarrhea to fatal colitis and occasionally occurring over two months following cessation of antibiotic therapy. Overgrowth of C. difficile resulting from antibiotic use, along with its production of A and B toxins, contributes to morbidity and mortality in these patients. Because of the associated risks, clindamycin should be reserved for serious infections for which the use of less toxic antimicrobial agents are inappropriate.
Austaclin-t is active against a number of gram-positive aerobic bacteria, as well as both gram-positive and gram-negative anaerobes. Resistance to clindamycin may develop, and is generally the result of base modification within the 23S ribosomal RNA. Cross-resistance between clindamycin and lincomycin is complete, and may also occur between clindamycin and macrolide antibiotics (e.g. erythromycin) due to similarities in their binding sites.

How Austaclin-t works
Austaclin-t 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
Austaclin-t dosage
At first wash the face or affected area gently with warm water or soap.
Clindacin lotion: When the skin is completely dried (about 30 minutes later) apply a thin film of Clindacin lotion to the entire affected area twice daily. Applied area should not be washed within 3 hours. Noticeable improvement is usually seen after about 6 weeks . However, 8 to 12 weeks of treatment may be required for maximum benefit. Eye, lip or nose contact should be avoided while applying Clindacin lotion.
Austaclin-t Lotion 1%: Clean the face or affected area gently with warm water or soap as recommended by the physician. After the skin is dried, apply a thin film of lotion to the affected areas twice daily, in the morning and in the evening.
Do not wash within three hours after using lotion. The treatment period is usually 6 weeks or as advised by the physician.
However, 8 to 12 weeks of treatment may be required for maximum benefit.
Austaclin-t 2% Vaginal preparation: One applicator full (approximately 5 gm) intravaginally at bedtime for 7 consecutive days. In patients in whom a shorter treatment course is desirable, a 3 day regimen has been shown to be effective.
Side Effects
Side effects are usually rare. Possible side-effects may includes skin rash, itching, oily skin, dryness, erythema, burning, change in skin color, diarrhea, colitis, GI disturbance etc.
Toxicity
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
Clindacin lotion is not for oral, ophthalmic, or Intravaginal use.
Avoid exposure to sunlight and sunlamps. Wear sunscreen daily.
Interaction
Austaclin-t enhance the action of other neuromuscular blocking agents. Therefore, it should be used with caution in patients receiving such agents. Antagonism has been demonstrated between clindamycin and erythromycin in vitro. Because of possible clinical significance, these two drugs should not be administered concurrently.
Food Interaction
- Take with a full glass of water. Austaclin-t may cause esophageal irritation if the dosage form becomes lodged.
- Take with or without food. Food does not appreciably alter the absorption of clindamycin.
Austaclin-t Drug Interaction

Austaclin-t Disease Interaction
Major: colitis, prematurityModerate: liver disease, renal dysfunction
Volume of Distribution
Austaclin-t 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
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
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: There is no adequate data for safe use in pregnancy. Animal studies showed no adverse effects on the fetus.
Lactation: It is not known that whether Austaclin-t is excreted through breast milk following topical administration. However, Clindacin lotion can be used during lactation with caution.
Contraindication
Austaclin-t is contraindicated in patients previously found to be sensitive to clindamycin or any of the ingredients of this medicine.
Acute Overdose
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.
Interaction with other Medicine
Austaclin-t enhance the action of other neuromuscular blocking agents. Therefore, it should be used with caution in patients receiving such agents. Antagonism has been demonstrated between clindamycin and erythromycin in vitro. Because of possible clinical significance, these two drugs should not be administered concurrently.
Storage Condition
Store between 20-25°C. Do not refrigerate or freeze.
