[Antidepressives and antidepressive interactions with other drugs].

During the therapy with antidepressive agents, for the reason of its duration, numerous drug-drug interactions may occur. Antidepressive agents inhibit P450 enzyme activity and interfere with other drug metabolism. Many interactions are acceptable from the clinical point of view, and some are seriously dangerous indicating a need for their better knowledge. The aim of this work is to point out the possible interactions between antidepressive agents and other drugs.

Topical treatment of standardised burns with herbal remedies in model rats.

Experimental studies of burns require the use of different animal models. The aim of this work was to establish experimental model of thermal injuries and to evaluate the effects of topical agents on healing of the burn wounds. Forty female Wistar rats were randomly classified in 4 groups and isolated for 2 weeks before the onset of experiment. Animals were primarily anaesthetized with pentobarbital-sodium and then shaved (skin area of their back with diameters 5 cm x 5 cm). A round metal stamp with contact area of 5 cm2 and total weight of 100 g was heated up to 80 degrees C and then applied without additional pressure on the depilated skin of the back for 14 seconds. This procedure produced a standardized burn wound. Induced burn wounds were immediately drowned in the 4 degrees C- water for 3 s in order to maintain microcirculation. After the inducement of thermal injures, all rats were treated with 1% silver sulfadiazine cream, herbal topical preparations or were not treated at all. Burn wounds were treated twice a day until the healing completion. The result of treatment application was a significant reduction of burn wound diameters. Herbal topical preparations expressed positive therapeutic effects on the parameters of burn wounds. The efficiency of silver sulfadiazine cream in burn wound healing was significantly more expressed in comparison to healing process in control group of animals (p < or = 0,001). We conclude that herbal topical preparations efficiently caused the completion of burn wound healing process without scar formation.

Modern approach in treatment of diabetes insipidus.

In this paper we have reviewed the position of desmopressin in the treatment of diabetes insipidus. Desmopressin is a synthetic analog of vasopressin, with more pronounced antidiuretic effect. It is treatment of choice in substitution therapy of diabetes insipidus. Its application before sleeping time can reduce nocturnal enuresis, so it has a place in the treatment of enuresis nocturna. Antidiuretic effect of desmopressin is the result of agonistic effect on V2 receptors in the renal tubules. The efficacy and safety of desmopressin in mentioned indications was confirmed in clinical studies.

[Enfuvirtide, mechanism of action and pharmacological properties].

Enfuvirtide is a new class of antiviral drug, fusion inhibitors, which interferate with penetration of HIV-1 in the cells. Enfuvirtide exhibits potent and selective inhibition of membrane of viral and cells. It specifically inhibits the function of the gp41 transmembrane glycoprotein of HIV-1. Enfurvitide showed significantly efficacy in the combination with other antiviral drugs in early stadium of HIV infection and in patients with antiretroviral resistention. Local injection site reactions are the most common adverse events associated with enfurvitide. However, the need for subcutaneous application of enfurvitide is a distinct disadvantage, especially in patients who are already burdened by complex oral therapy.

Testing of analgesic effect of fluoxetine.

Fluoxetine is used in treatment of depression caused by a variety of different factors and from year to year new indications are being added, especially in conditions followed with strong bouts of pain. Additional fluoxetine based therapy that is known to help in improvement of mental state and mood stabilization can significantly increase analgesic effects. Analgesic effects of fluoxetine as well as of fluoxetine in combination with morphine were analyzed on albino mice of both genders. The sense of pain was induced by thermal stimulus by the method of hot plate. Analgesic effect was measured 30, 60, 90 and 120 minutes after a single i.p. administration of fluoxetine in following dosages: 5, 10 and 20 mg/kg. The control group was treated with 0.1 ml/10 g physiological solution. Test group injected with morphine s.c. (7 mg/kg) was used to observe the effect of fluoxetine in combination with morphine. Fluoxetine applied in 5 mg/kg dosage causes increased pain reaction 60 and 90 minutes (p=0.049 and p=0.002) (t-test) following application when compared with corresponding values of control group. When fluoxetine is applied in 10 mg/kg dosage duration of pain reaction is significantly increased after 30 (p=0.01), 60 (p=0.001) and 90 minutes (p=0.026), when compared to the control group. When fluoxetine is applied in 20 mg/kg dosage duration of pain reaction is increased 60 and 120 minutes (p<0.001) after application when compared to the control group. After application of fluoxetine (5 mg/kg) in combination with morphine, reaction time to pain is significantly extended (p<0.001) 60, 90 and 120 minutes after application when compared to the control group injected exclusively with morphine. Fluoxetine causes analgesic effect in all three applied dosages as well as it significantly increases analgesic effect when applied in 5 mg/kg dosage in combination with morphine.

[Genotoxicity evaluation of paracetamol applying Allium test].

Paracetamol genotoxic potential was evaluated among different concentrations, applying Allium test on Allium cepa. Total number of roots, number of dark roots, the length of the longest root, the average root, and the shortest root were determined. Statistically significant differences among total number of roots (p > 0.05) was observed at concentrations of 50 microg/ml and 100 microg/ml, and highly statistically significant differences at concentrations of 5 microg/ml and 25 microg/ml, while at the highest concentration (400 microg/ml) was observed statistically significant higher number of roots in comparation to all other concentrations of paracetamol and control group. The results of research suggest the concentrations of 5 microg/ml, 25 microg/ml and 400 microg/ml for further evaluation of paracetamol mutagenic potential.

[Transdermal drug delivery systems].

Transdermal drug delivery systems are pharmaceutical preparations, intended to be applied to the unbroken skin in order to deliver the active ingredient(s) to the systemic circulation after passing through the skin barrier. Transdermal patches are formulated in different ways, but normally they consist of release liner, adhesive layer and backing layer. Active ingredient(s) can be incorporated in reservoir, matrix, adhesive, membrane-matrix and microreservoir. The releasing rate of active substances from patches is controlled by membrane, matrix and adhesive. Only several transdermal systems are available on the market today, because for the penetration of most substances skin represents a strong barrier. With transdermal systems it is possible to obtain a controllable and sustained plasma levels, to minimaze the risk of undesirable side effects and to avoid the hepatic first- pass metabolism. These devices are easy to apply and also to remove from the skin. Of a great pharmaceutical interest are also socalled cosmetic patches. They are applied with aim of cleaning and protecting the skin.

Experimental model of the burn wound topical treatment.

BACKGROUND AND PURPOSE: Clinical research of drugs is a researching step subsequent to the preclinical studies in experimental animals. The aim of our research was to evaluate animal model of wound healing process after the burn inducement and effects of the ointment containing natural plants on the process of burn healing. MATERIAL AND METHODS: Burn wounds were experimentally induced in two species of experimental animals which were treated with topically applied herbal preparation with concomitant monitoring of the healing process. Experimental groups (1) of 15 animals each (mice and rats), while control group (2) of 10 animals each (mice and rats) that were not being treated with herbal ointment. After the hair removal, burn was induced on the back of animals by heated brass seal. Different clinical symptoms including oedema of surrounding tissue, redness, exudation, size of the burn surface, histological and microbiological findings were monitored on the days 1, 3, 7, 14 and 21. A statistically significant difference was observed throughout descriptive statistics and paired Student's t-test. CONCLUSION: Physiological healing processes of the acute burn wound following the topical application of herbal preparation can be monitored on the utilized animal model. A three-week treatment resulted in the 90% of completed epithelization in both animal species, indicating the effectiveness of topically applied herbal preparation.

[Glimepiride--an oral antidiabetic agent].

Glimepiride is the oral antidiabetic, second-generation sulfonylurea. It is structurally similar to glyburide. Glimepiride exhibited more potent glucose-lowering effects than glyburide and longer duration of hypoglycemic effect. Glimepiride is useful in the treatment of non-insulin-dependent (type II) diabetes mellitus. Glimepiride is indicated as an adjunct to diet and exercise for non-insulin dependent diabetes mellitus. Glimepiride reduces glucose levels blood by stimulating insulin release from functional pancreatic beta cells in response to glucose. Glimepiride in daily dose 1 to 8 mg is causing a dose-related decrease blood glucose levels and glycosylated hemoglobin fasting state and postprandially. If the maximum dose of glimepiride fails to lower blood glucose sufficiently, metformine or insuline may be added to glimepiride monotherapy. Glimepiride is very safe drug and adverse effects causing by glimepiride are very rare. The risk of hypoglycemia after use of glimepiride is very small, therefore is the therapy with glimepiride is more preferable than the therapy with glibenclamide.
