DRUGS & SUPPLEMENTS
How often in a day do you take medicine? How many times?
Amklok is an antibiotic of semisynthetic broad-spectrum penicillin group. This medication has a bactericidal effect by suppressing the synthesis of bacterial cell walls. Amklok (Ampicillin) is active against aerobic gram-positive bacteria: Staphylococcus spp. (with the exception of strains producing penicillinase), Streptococcus spp., Enterococcus spp., Listeria monocytogenes; aerobic gram-negative bacteria: Neisseria gonorrhoeae, Neisseria meningitidis, Escherichia coli, Shigella spp., Salmonella spp., Bordetella pertussis, some strains of Haemophilus influenzae. Amklok (Ampicillin) destroyed by penicillinase. This drug is acid-resistant.
After oral administration Amklok (Ampicillin) is well absorbed from the gastrointestinal tract. This medicine is distributed in most organs and tissues; crosses the placental barrier, poorly penetrates the BBB. When inflammation of the meninges, BBB permeability increases dramatically. 30% of Amklok (Ampicillin) is metabolized in the liver. This medication is excreted in the urine and bile.
Infectious-inflammatory diseases caused by organisms susceptible to Amklok (Ampicillin): including ear infections, throat, nose, odontogenic infections, bronchopulmonary infections, acute and chronic urinary tract infections, gastrointestinal infections (including salmonella, cholecystitis), gynecological infections, meningitis, endocarditis, septicemia, sepsis, rheumatic fever, erysipelas, scarlet fever, infections of skin and soft tissues.
The dosing regimen of Amklok is set individually depending on the severity, localization of infection and sensitivity of the pathogen.
For adults for oral administration a single dose of this medication is 250-500 mg, the multiplicity of the reception is 4 times / day. The dose for children weighing up to 20 kg is 12.5-25 mg / kg every 6 hours.
For IV and IM using the single dose for adults is 250-500 mg every 4-6 hours; for children the single dose is 25-50 mg / kg.
The duration of treatment depends on the localization of infection and features of the disease.
The maximum oral daily dose for adults is 4 g, for IM and IV administration - 14 g.
Allergic reactions: urticaria, erythema, angioedema, rhinitis, conjunctivitis, rarely - fever, joint pain, eosinophilia, extremely rare - anaphylactic shock.
Digestive system: nausea, vomiting.
The effects caused by chemotherapeutic action: oral candidiasis, vaginal candidiasis, intestinal dysbiosis, colitis caused by Clostridium difficile.
Infectious mononucleosis, lymphatic leukemia, increased sensitivity to Amklok (Ampicillin) and other penicillins, abnormal liver function.
Perhaps the use of Amklok during pregnancy if it may be needed. Amklok (Ampicillin) is excreted in breast milk in low concentrations. If necessary to use Amklok (Ampicillin) in the lactation period it should be solved the issue of termination of breastfeeding.
Category effects on the fetus by FDA - B.
In the course of treatment with Amklok (Ampicillin) there is need the regular control of renal function, liver and peripheral blood picture. Patients with impaired renal function requires correction dosing regimen in accordance with the values of CCr.
When used in high doses in patients with renal insufficiency it may be toxic effects on the CNS.
For using of Amklok (Ampicillin) in patients with bacteremia (sepsis) it can be bacteriolysis reaction (Jarisch-Herxheimer reaction).
Simultaneous administration of Amklok (Ampicillin) with bactericidal antibiotics (including aminoglycosides, cephalosporins, cycloserine, vancomycin, rifampicin) there is manifested synergism; with bacteriostatic antibiotics (including macrolides, chloramphenicol, lincosamides, tetracyclines, sulfonamides) - antagonism.
Amklok (Ampicillin) enhances the effect of indirect anticoagulants by inhibiting the intestinal microflora, reduces the synthesis of vitamin K and prothrombin index.
Amklok (Ampicillin) decreases the effect of drugs in the process of metabolism which produce PABA.
Probenecid, diuretics, allopurinol, phenylbutazone, NSAIDs decrease the tubular secretion of Amklok (Ampicillin) which may be accompanied by an increase in its concentration in blood plasma.
Antacids, glucosamine, laxatives, aminoglycosides slow down and reduce the absorption of Amklok (Ampicillin) Upha Corporation. Ascorbic acid increases the absorption of Amklok (Ampicillin).
Amklok (Ampicillin) decreases the effectiveness of oral contraceptives.
Symptoms: the toxic effect on the central nervous system (especially in patients with renal insufficiency), nausea, vomiting, diarrhea, impaired water and electrolyte balance (as a consequence of vomiting and diarrhea).
Treatment: gastric lavage, activated charcoal, saline laxatives, a maintain of water and electrolyte balance, symptomatic therapy. This drug is derived by means of hemodialysis.
To reduce the development of drug-resistant bacteria and maintain the effectiveness of Amklok (Dicloxacillin) sodium capsules USP and other antibacterial drugs, Amklok (Dicloxacillin) sodium capsules USP should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
Amklok (Dicloxacillin) is indicated in the treatment of infections caused by penicillinase-producing staphylococci which have demonstrated susceptibility to the drug. Cultures and susceptibility tests should be performed initially to determine the causative organisms and their sensitivity to the drug. (see CLINICAL PHARMACOLOGY – Susceptibility Plate Testing).
Amklok (Dicloxacillin) may be used to initiate therapy in suspected cases of resistant staphylococcal infections prior to the availability of laboratory test results. The penicillinase-resistant penicillins should not be used in infections caused by organisms susceptible to penicillin G. If the susceptibility tests indicate that the infection is due to an organism other than a resistant staphylococcus, therapy should not be continued with a penicillinase-resistant penicillin.
A history of a hypersensitivity (anaphylactic) reaction to any penicillin is a contraindication.
Serious and occasionally fatal hypersensitivity (anaphylactic shock with collapse) reactions have occurred in patients receiving penicillin. The incidence of anaphylactic shock in all penicillin-treated patients is between 0.015% and 0.04%. Anaphylactic shock resulting in death has occurred in approximately 0.002% of the patients treated. Although anaphylaxis is more frequent following a parenteral administration, it has occurred in patients receiving oral penicillins.
When penicillin therapy is indicated, it should be initiated only after a comprehensive patient drug and allergy history has been obtained. If an allergic reaction occurs, the drug should be discontinued and the patient should receive supportive treatment, e.g., artificial maintenance of ventilation, pressor amines, antihistamines and corticosteroids. Individuals with a history of penicillin hypersensitivity may also experience allergic reactions when treated with a cephalosporin.
Prescribing Amklok sodium capsules USP in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.
Amklok (Dicloxacillin) should generally not be administered to patients with a history of sensitivity to any penicillin.
Penicillin should be used with caution in individuals with histories of significant allergies and/or asthma. Whenever allergic reactions occur, penicillin should be withdrawn unless, in the opinion of the physician, the condition being treated is life-threatening and amenable only to penicillin therapy.
The oral route of administration should not be relied upon in patients with severe illness, or with nausea, vomiting, gastric dilatation, cardiospasm or intestinal hypermotility. Occasionally, patients will not absorb therapeutic amounts of orally administered penicillin.
The use of antibiotics may result in overgrowth of nonsusceptible organisms. If new infections due to bacteria or fungi occur, the drug should be discontinued and appropriate measures taken.
Patients should be counselled that antibacterial drugs including Amklok (Dicloxacillin) sodium capsules USP should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When Amklok (Dicloxacillin) sodium capsules USP are prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by Amklok (Dicloxacillin) sodium capsules USP or other antibacterial drugs in the future.
Patients receiving penicillins should be given the following information and instructions by the physician:
Bacteriologic studies to determine the causative organisms and their susceptibility to the penicillinase-resistant penicillins should be performed. In the treatment of suspected staphylococcal infections, therapy should be changed to another active agent if culture tests fail to demonstrate the presence of staphylococci.
Periodic assessment of organ system function, including renal, hepatic and hematopoietic, should be made during prolonged therapy with the penicillinase-resistant penicillins.
Blood cultures, white blood cell and differential cell counts should be obtained prior to initiation of therapy and at least weekly during therapy with penicillinase-resistant penicillins.
Periodic urinalysis, blood urea nitrogen and creatinine determinations should be performed during therapy with the penicillinase-resistant penicillins and dosage alterations should be considered if these values become elevated. If any impairment of renal function is suspected or known to exist, a reduction in the total dosage should be considered and blood levels monitored to avoid possible neurotoxic reactions (see DOSAGE AND ADMINISTRATION).
SGOT and SGPT values should be obtained periodically during therapy to monitor for possible liver function abnormalities.
Tetracycline, a bacteriostatic antibiotic, may antagonize the bactericidal effect of penicillin and concurrent use of these drugs should be avoided.
No long-term animal studies have been conducted with these drugs.
Studies on reproduction in rats and rabbits reveal no fetal or maternal abnormalities before conception and continuously through weaning (one generation).
Reproduction studies performed in the mouse, rat and rabbit have revealed no evidence of impaired fertility or harm to the fetus due to the penicillinase-resistant penicillins. Human experience with the penicillins during pregnancy has not shown any positive evidence of adverse effects on the fetus. There are, however, no adequate or well-controlled studies in pregnant women showing conclusively that harmful effects of these drugs on the fetus can be excluded. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
Penicillins are excreted in breast milk. Caution should be exercised when penicillins are administered to a nursing woman.
Because of incompletely developed renal function in newborns, penicillinase-resistant penicillins (especially methicillin) may not be completely excreted, with abnormally high blood levels resulting. Frequent monitoring of blood levels is advisable in this group, with dosage adjustments when necessary. All newborns treated with penicillins should be monitored closely for clinical and laboratory evidence of toxic or adverse effects (see DOSAGE AND ADMINISTRATION).
The reported incidence of allergic reactions to penicillin ranges from 0.7% to 10%. Sensitization is usually the result of treatment, but some individuals have had immediate reactions to penicillin when first treated. In such cases, it is thought that the patients may have had prior exposure to the drug via trace amounts present in milk and vaccines.
Two types of allergic reactions to penicillin are noted clinically, immediate and delayed.
Immediate reactions usually occur within 20 minutes of administration and range in severity from urticaria and pruritus to angioneurotic edema, laryngospasm, bronchospasm, hypotension, vascular collapse and death. Such immediate anaphylactic reactions are very rare (see WARNINGS) and usually occur after parenteral therapy, but have occurred in patients receiving oral therapy. Another type of immediate reaction, an accelerated reaction, may occur between 20 minutes and 48 hours after administration and may include urticaria, pruritus and fever. Although laryngeal edema, laryngospasm and hypotension occasionally occur, fatality is uncommon.
Delayed allergic reactions to penicillin therapy usually occur after 48 hours and sometimes as late as two to four weeks after initiation of therapy. Manifestations of this type of reaction include serum sickness-like symptoms (i.e., fever, malaise, urticaria, myalgia, arthralgia, abdominal pain) and various skin rashes. Nausea, vomiting, diarrhea, stomatitis, black or hairy tongue and other symptoms of gastrointestinal irritation may occur, especially during oral penicillin therapy.
Neurotoxic reactions similar to those observed with penicillin G may occur with large intravenous doses of the penicillinase-resistant penicillins, especially with patients with renal insufficiency.
Renal tubular damage and interstitial nephritis have been associated with the administration of methicillin sodium and, infrequently, with the administration of nafcillin and oxacillin. Manifestations of this reaction may include rash, fever, eosinophilia, hematuria, proteinuria and renal insufficiency. Methicillin-induced nephropathy does not appear to be dose-related and is generally reversible upon prompt discontinuation of therapy.
Agranulocytosis, neutropenia and bone marrow depression have been associated with the use of methicillin sodium and nafcillin. Hepatotoxicity, characterized by fever, nausea and vomiting associated with abnormal liver function tests, mainly elevated SGOT levels, has been associated with the use of oxacillin.

Bacteriologic studies to determine the causative organisms and their sensitivity to the penicillinase-resistant penicillins should always be performed. Duration of therapy varies with the type and severity of infection as well as the overall condition of the patient, therefore it should be determined by the clinical and bacteriological response of the patient. In severe staphylococcal infections, therapy with penicillinase-resistant penicillins should be continued for at least 14 days. Therapy should be continued for at least 48 hours after the patient has become afebrile, asymptomatic and cultures are negative. The treatment of endocarditis and osteomyelitis may require a longer term of therapy.
Concurrent administration of the penicillinase-resistant penicillins and probenecid increases and prolongs serum penicillin levels.
Probenecid decreases the apparent volume of distribution and slows the rate of excretion by competitively inhibiting renal tubular secretion of penicillin. Penicillin-probenecid therapy is generally limited to those infections where very high serum levels of penicillin are necessary.
Oral preparations of the penicillinase-resistant penicillins should not be used as initial therapy in serious, life-threatening infections (see PRECAUTIONS - General). Oral therapy with the penicillinase-resistant penicillins may be used to follow up the previous use of a parenteral agent as soon as the clinical condition warrants. For intramuscular gluteal injections, care should be taken to avoid sciatic nerve injury. With intravenous administration, particularly in elderly patients, care should be taken because of the possibility of thrombophlebitis.
NB: INFECTIONS CAUSED BY GROUP A BETA-HEMOLYTIC STREPTOCOCCI SHOULD BE TREATED FOR AT LEAST 10 DAYS TO HELP PREVENT THE OCCURRENCE OF ACUTE RHEUMATIC FEVER OR ACUTE GLOMERULONEPHRITIS.
