Sulfanilamide preparations are a special category of medicines. It contains various medicines. The choice of one or another remedy depends on the course of the pathology, the pathogen, and also on how certain sulfonamides are tolerated by the patient. Classification involves grouping medicines into one or another group in accordance with their pharmacological characteristics.
Medicines of this category are presented in the form of tablets, as well as white or slightly yellowish powders, odorless and tasteless. Sulfanilamide preparations are poorly soluble in water.
Medicines have an antimicrobial effect. This activity is due to the ability of drugs to disrupt the absorption of substances important for their development and life by microbes.
It is necessary to take sulfa drugs strictly according to the scheme prescribed by the doctor. Premature cessation of therapy or the use of drugs in small doses can lead to negative consequences. Thus, resistant strains of pathogens may develop.microorganisms that are not amenable to the effects of medicines in the future.
Today, different sulfonamides are used in practice. The list of drugs is quite voluminous.
When prescribing this or that medication, the degree of absorption of the drug from the gastrointestinal tract, the speed and routes of excretion, as well as the ability to penetrate into certain tissues and organs are taken into account, among other things.
For example, such sulfanilamide preparations as "Sulfadimezin", "Etazol", "Norsulfazol", "Streptocid" and others are characterized by rapid absorption and the ability to quickly accumulate in organs and blood in bacteriostatic concentrations. This allows them to be used in the treatment of various pathologies of an infectious nature, provoked by staphylococci, pneumococci, streptococci, meningococci and other cocci, vibrios, protozoa, chlamydia.
Other sulfanilamide preparations, for example, "Sulgin" and "Fthalazol", are absorbed more slowly, are present in high concentrations in the intestine for a relatively long time, excreted mainly with feces. In this regard, such medicines are used in the treatment of gastrointestinal pathologies.
If necessary, sulfa drugs can be prescribed in different combinations. So, drugs that are poorly and well absorbed are allowed for the simultaneous use.
Medications may cause side effects. In particular, allergic reactions often appear, vomiting, nausea, neuritis, dermatitis, and so on. Due to badsolubility, sulfonamides can precipitate in the kidneys in the form of crystals, blocking the urinary tract. Therefore, when prescribing these drugs, a plentiful alkaline drink is recommended. Given the spectrum of side effects, drugs in this group are used only as prescribed by a doctor. It should be remembered that self-medication can lead to very negative consequences. Before using the prescribed medication, you must study the annotation.
