There is a vast practice of using antimalarial drugs, RAS inhibitors, serine protease inhibitors, inhibitors of the RNA-dependent RNA polymerase of the virus and immunosuppressants for the treatment of the severe form of COVID-19, which often occurs in patients with chronic diseases and older persons. Currently, the clinical efficacy of these drugs for COVID-19 has not been proven yet. Side effects of antimalarial drugs can worsen the condition of patients and increase the likelihood of death. Peptides, given their physiological mechanism of action, have virtually no side effects. Many of them are geroprotectors and can be used in patients with chronic diseases. Peptides may be able to prevent the development of the pathological process during COVID-19 by inhibiting SARS-CoV-2 virus proteins, thereby having immuno- and bronchoprotective effects on lung cells, and normalizing the state of the hemostasis system. Immunomodulators (RKDVY, EW, KE, AEDG), possessing a physiological mechanism of action at low concentrations, appear to be the most promising group among the peptides. They normalize the cytokines’ synthesis and have an anti-inflammatory effect, thereby preventing the development of disseminated intravascular coagulation, acute respiratory distress syndrome and multiple organ failure.

Inflammatory Effect

Objective of the Review: To analyse available information on the nimesulide mechanism of action, namely of recent studies of COXindependent effects of nimesulide, affecting primarily histamine-mediated reactions. Key Points. Fast and lasting anti-inflammatory and analgetic effects of nimesulide are a result of a number of actions not associated with cyclooxygenase 2 inhibition. Of utmost interest are effects associated with suppression of immune and non-immune histamine secretion. Conclusion. An interesting effect of nimesulide is an impact on histamine secretion; it explains more pronounced analgetic and anti-inflammatory effect of nimesulide and a low risk of respiratory and GIT side effects. Keywords: nonsteroidal anti-inflammatory drugs, cyclooxygenase, histamine, nimesulide.

Background & Objective: :Nitrogen mustard derivatives form one of the major classes of anti-cancer agents in USFDA approved drugs list. These are polyfunctional alkylating agents which are distinguished by a unique mechanism of adduct formation with DNA involving cross-linking between guanine N-7 of one strand of DNA with the other. The generated cross-linking is irreversible and leads to cell apoptosis. Hence it is of great interest to explore this class of anticancer alkylating agents.Methods::An exhaustive list of reviews, research articles, patents, books, patient information leaflets, and orange book is presented and the contents related to nitrogen mustard anti-cancer agents have been reviewed. Attempts are made to present synthesis schemes in a simplified manner. The mechanism of action of the drugs and their side effects are also systematically elaborated.Results::This review provides a platform for understanding all aspects of such drugs right from synthesis to their mechanism of action and side effects, and lists USFDA approved ANDA players among alkylating anticancer agents in the current market.Conclusion: :Perusing this article, generic scientists will be able to access literature information in this domain easily to gain insight into the nitrogen mustard alkylating agents for further ANDA development. It will help the scientific and research community to continue their pursuit for the design of newer and novel heterocyclic alkylating agents of this class in the coming future.

: Obesity is a major lifestyle disorder and it is correlated with several ailments. The prevalence of obesity has elevated over the years and it has become a global health problem. The drugs presently used for managing obesity have several side-effects associated with them such as diarrhoea, leakage of oily stools, etc. On the contrary, herbal plants and natural products are considered safe for use because they have lesser side effects. New compounds isolated from medicinal plants are screened and identified to determine their effectiveness and potential in preventing abnormal weight gain. In this review, the medicinal plants and natural materials were surveyed across the literature to cover those that have potential for managing and controlling weight gain, and their mechanism of action, active component, and experimental methodologies are also included. These herbal products can be developed as formulations for therapeutic use in obesity. The herbal plants mentioned in the review are classified based on their mechanism of action: inhibition of pancreatic lipase and appetite suppression activities. The ability to inhibit pancreatic lipase enzyme has been used to determine the effectiveness of herbal products for the prevention of abnormal weight gain because of its action on dietary fat and suppression of appetite. This review is an attempt to summarize the herbal plants and natural products that can be used to develop formulations effective in controlling weight gain and obesity.

AbstractThe paper presents an overview of the use of natural therapeutic agents in combating parasitic diseases. Nowadays there is increasing demand for proven plant therapies, which often are found to be more effective than synthetic pharmaceuticals in chronic diseases. In many cases herbal preparations perfectly supplement the conventional treatment and at the same time do not cause side effects. On the pharmaceutical market there are many drugs of plant origin which have been applied in the treatment of parasitic diseases. However, researchers are still looking for new plants, or specific substances isolated from them, which can be used in therapy. In this paper, drugs of plant origin used in the treatment of amoebiasis, giardiasis, malaria, leishmaniasis, trypanosomiasis and acanthamoebiasis are described.

Inflammatory Effect

Mefenamic acid (MA) is one of the non-steroidal anti-inflammatory drugs, it is widely used probably due to having both anti-inflammatory and analgesic activity, the main side effects of mefenamic acid include gastrointestinal tract (GIT) disturbance mainly diarrhea, peptic ulceration, and gastric bleeding. The analgesic effects of NSAIDs are probably linked to COX-2 inhibition, while COX-1 inhibition is the major cause of this classic adverse effects. Introduction of thiazolidinone may lead to the increase in the bulkiness leads to the preferential inhibition of COX-2 rather than COX-1 enzyme. The study aimed to synthesize derivatives of mefenamic acid with more potency and to decrease the drug's potential side effects, new series of 4-thiazolidinone derivatives of mefenamic acid were synthesized IVa-g. The synthetic procedures for target compounds and their intermediates are designed to be as follows: acylation of secondary amine of mefenamic acid by chloroacetylchloride to produce compound (I), then reaction between compound (I) and hydrazine hydrate to form hydrazine derivative of mefenamic acid (compound II). After that, Schiff base formation by addition of seven benzaldehyde derivatives and finally, cyclization in presence of thioglycolic acid to form 4-thiazolidinone heterocyclic ring. The characterization of the titled compounds has been established on the basis of their spectral FTIR, 1HNMR data, and by measurements of their physical properties. In vivo acute anti-inflammatory effect of the synthesized compounds was evaluated in rats using egg-white induced edema model of inflammation. The tested compounds and the reference drug produced significant reduction of paw edema with respect to the effect of dimethyl sulfoxide 10%v/v (control group). Compound IVe showed more potent effect than mefenamic acid at 240-300 min, while at time 300 min, compounds IVa and IVd exhibit more potent anti-inflammatory effect than mefenamic acid (50mg/kg, i.p.) as they reduced paw edema significantly more than mefenamic acid at mentioned intervals (p<0.05) . On the other hand compound IVc exhibited lower anti-inflammatory effect.

Objective: To evaluate health care related to medication regimens among institutionalized elders in Damanhour, Beheira Governate, Egypt. Methods: A prospective, multi-centered, observational study was conducted in the two elderly residential homes in Damanhour between March and May 2017. A questionnaire was developed and validated to test for elderly socio-economic, chronic diseases, current therapy adherence, vaccination history and patient education. Descriptive and quantitative analysis were performed. Results: sixty-three elderly residents were included in the study. The sample showed broad socioeconomic variability posing a true reflection of Egyptian population. 63.5% had no hearing problems, 31.7% had proper vision and 57% could move with no help. More than three quarters had chronic diseases of which 58.7% were previously hospitalized. The most prevalent diseases were hypertension, diabetes and arthritis 46%, 41.3%, 26.9% respectively. Only 7.9% and 4.7% showed chronic liver and kidney diseases, respectively and less than 10% suffered from respiratory related diseases. No alcohol drinker, 25.3% were smokers and 58.7% drank caffeine. Only 25.3% of residents showed full adherence to their medication pattern. Approximately 80% of residents never received proper patient education. Forty-three residents did not know the indication of their medications and 92% ignored its side effects. Conclusion: Absence of proper medical care exposure for the elderly residents was reflected in their low medication adherence, adverse side effects and hospitalization. We suggest extension of the national medical insurance system to include larger number of elderly population. To monitor the care given concerning medication, a daily resident gerontological nurse needs to be assigned, visits by clinical pharmacists weekly or bi-weekly from the nearby governmental hospital can improve improper medication. doi: https://doi.org/10.12669/pjms.36.4.1923 How to cite this:Algameel M.

Anthocyanins are natural pigments abundant in various fruits and berries that are involved in the prevention of various chronic diseases. Their low concentrations in plasma and urine are explained in part by their complex chemistry and the formation of still uncharacterised metabolites. The aim of the present study was to follow the distribution of anthocyanins in the body using 14C-labelled cyanidin 3-O-glucoside (Cy3G) fed by gavage to mice. After the administration of 22·2 kBq 14C-Cy3G (0·93 mg), radioactivity was detected in most organs tested over the following 24 h with a peak observed in inner tissues at 3 h. The major fraction of the radioactivity (44·5 %) was found in the faeces collected 24 h after ingestion. At 3 h after oral administration of 141 kBq 14C-Cy3G (4·76 mg), most of the radioactivity (87·9 % of intake) was recovered in the gastrointestinal (GI) tract, especially in the small intestine (50·7 %) and the caecum (23 %). At this time, 3·3 % of the radioactivity was detected in urine. There was minimal accumulation (0·76 %) of radioactivity in tissues outside the GI tract. Distribution of radioactivity varied among organs, with liver, gallbladder and kidneys showing the highest radioactivity. Taken as a whole, these results show that Cy3G is poorly absorbed in the mouse.

The authors summarize the harmful and understudied aspects of the overuse of benzodiazepines. Increased and longer-term use of benzodiazepines has been observed to lead to side effects such as sedation, cognitive issues, abuse, and dependence, as well as many other unanticipated side effects that do not fit their known mechanism of action in the central nervous system. Data also shows a correlation between concomitant use of benzodiazepines and opioids and increased risk of death from overdose. The authors advocate for stricter guidelines for prescribing benzodiazepines, as well as close clinical monitor and shorter-term treatment plans.
