Actions of Vistadrox in details

The action of the drug on the human body is called Pharmacodynamics in Medical terminology. To produce its effect and to change the pathological process that is happening the body and to reduce the symptom or cure the disease, the medicine has to function in a specific way. The changes it does to the body at cellular level gives the desired result of treating a disease. Drugs act by stimulating or inhibiting a receptor or an enzyme or a protein most of the times. Medications are produced in such a way that the ingredients target the specific site and bring about chemical changes in the body that can stop or reverse the chemical reaction which is causing the disease.

Pharmacology: Pharmacokinetics: Vistadrox is rapidly absorbed after oral administration. Following single doses of 500 and 1000 mg, average peak serum concentrations were approximately 16 and 28 mcg/mL, respectively. Measurable levels were present 12 hrs after administration. Over 90% of Vistadrox is excreted unchanged in the urine within 24 hrs. Peak urine concentrations are approximately 1800 mcg/mL during the period following a single 500-mg oral dose. Increases in dosage generally produce a proportionate increase in Vistadrox urinary concentration. The urine antibiotic concentration, following a 1-g dose, was maintained well above the MIC of susceptible urinary pathogens for 20-22 hrs.

Microbiology: In vitro tests demonstrate that the cephalosporins are bactericidal because of their inhibition of cell wall synthesis. Vistadrox has been shown to be active against the following organisms both in vitro and in clinical infections : β-hemolytic streptococci, Staphylococci, including penicillinase-producing strains, Streptococcus (Diplococcus) pneumoniae, Escherichia coli, Proteus mirabilis, Klebsiella sp, Moraxella (Branhamella) catarrhalis.

Note: Most strains of Enterococcus faecalis (formerly Streptococcus faecalis) and Enterococcus faecium (formerly Streptococcus faecium) are resistant to Vistadrox. It is not active against most strains of Enterobacter sp, Morganella morganii (formerly Proteus morganii) and P. vulgaris. It has no activity against Pseudomonas sp and Acinetobacter calcoaceticus (formerly Mima and Herellea sp).

How should I take Vistadrox?

Take Vistadrox only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered.

You or your child may take Vistadrox with or without food.

Shake the oral liquid well before each use. Measure the medicine with a marked measuring spoon, oral syringe, or medicine cup. The average household teaspoon may not hold the right amount of liquid.

Keep using Vistadrox for the full treatment time, even if you feel better after the first few doses. Your infection may not clear up if you stop using the medicine too soon.

Dosing

The dose of Vistadrox will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of Vistadrox. If your dose is different, do not change it unless your doctor tells you to do so.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

Missed Dose

If you miss a dose of Vistadrox, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.

Storage

Keep out of the reach of children.

Do not keep outdated medicine or medicine no longer needed.

Ask your healthcare professional how you should dispose of any medicine you do not use.

Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.

Store the oral liquid in the refrigerator. Throw away any unused medicine after 14 days.

Vistadrox administration

Administration of drug is important to know because the drug absorption and action varies depending on the route and time of administration of the drug. A medicine is prescribed before meals or after meals or along with meals. The specific timing of the drug intake about food is to increase its absorption and thus its efficacy. Few work well when taken in empty stomach and few medications need to be taken 1 or 2 hrs after the meal. A drug can be in the form of a tablet, a capsule which is the oral route of administration and the same can be in IV form which is used in specific cases. Other forms of drug administration can be a suppository in anal route or an inhalation route.

Take this medication exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.

Take this medicine with a full glass of water.

Take this medication for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated. Vistadrox will not treat a viral infection such as the common cold or flu.

Vistadrox can be taken on an empty stomach or with food or milk if it causes stomach upset.

Shake the liquid form of Vistadrox well before measuring a dose. To ensure that you get a correct dose, measure the suspension with a dose-measuring spoon or cup, not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist where you can get one.

This medication can cause you to have false results with certain medical tests, including urine glucose (sugar) tests. Tell any doctor who treats you that you are using Vistadrox.

Store the tablets and capsules at room temperature away from moisture and heat.

Store Vistadrox oral liquid in the refrigerator. Do not allow it to freeze. Throw away any unused medication that is older than 14 days.

Vistadrox pharmacology

Pharmacokinetics of a drug can be defined as what body does to the drug after it is taken. The therapeutic result of the medicine depends upon the Pharmacokinetics of the drug. It deals with the time taken for the drug to be absorbed, metabolized, the process and chemical reactions involved in metabolism and about the excretion of the drug. All these factors are essential to deciding on the efficacy of the drug. Based on these pharmacokinetic principles, the ingredients, the Pharmaceutical company decides dose and route of administration. The concentration of the drug at the site of action which is proportional to therapeutic result inside the body depends on various pharmacokinetic reactions that occur in the body.
