Willow Tree

Salicylates have been derived from the willow tree bark. Acetylsalicylic acid has analgesic, antipyretic and anti-inflammatory actions. Salicylate elimination happens throughout dual pathways via the invention of salicyluric acid and salicyl phenolic glucuronide. Salicylic acid is renally cleared, which can be escalated by ascending the urinary pH. Medicines like antacids can accelerate renal clearance as they ascend urinary pH. Aspirin should be used with chariness in children taking some distinctive medications. Levels of methotrexate, valproic acid, phenytoin, and disparate non-steroidal anti-inflammatory drugs (tolmetin, diclofenac) perhaps escalated in children who are also taking aspirin.

Model Drug

The article describes the production of starch film as a carrier of a model drug substance from the group of non-steroidal anti-inflammatory drugs (NSAIDs). An analgesic/anti- inflammatory drug was put into aqueous starch solution, and next a film was formed. The following solid drug substances were included in the tests: acetylsalicylic acid, salicylic acid, ibuprofen lysine salt, naproxen in the form of acid, and sodium salt. Solutions were obtained from ibuprofen lysine salt and naproxen sodium, whereas the other drugs enabled to obtain aqueous suspensions. Such a drug substance was mixed with aqueous starch solution to obtain a film. Forming a film under laboratory conditions involved spreading aqueous starch solution containing a drug on a flat heated surface and evaporating water. The films obtained were transparent. They were then dried for a period of 24 hours at a temperature of 20 °C and 50% relative air humidity. Next their mechanical properties were studied. Starch films which contained therapeutic substances were characterised by Fourier transform infrared spectroscopy (FTIR). There were slight differences between the spectra of films containing a drug substance and those of films containing both starch and a drug substance, which implies weak intermolecular reactions. Scanning electron microscope (SEM) images of cross-sections of the starch films with a drug substance were taken, which indicated their uniform morphological structure. The release rate of the drug from each film to an acetate buffer pH 4.5 (acetylsalicylic acid and salicylic acid) or phosphate buffer pH 7.38 (ibuprofen lysine salt and naproxen) was determined in vitro with the paddle method. This procedure took up to 90 min. Acetylsalicylic acid and salicylic acid were almost completely released from the starch film as early as in the first minutes of the procedure, with a maximum value of around 90%. The release of ibuprofen lysine salt and naproxen in the form of acid from the starch film was partial, about 40%. The release of naproxen sodium from the starch film was time-proportional, and there was a tendency towards further release.

It is known that acetylsalicylic acid, an anti-inflammatory and anti-mitochondrial drug, targets structure development and functions of yeasts depending on elevated levels of mitochondrial activity. Using antibody probes, we previously reported that sporangia of Mucor circinelloides also contain increased mitochondrial activity, yielding high levels of 3-hydroxyoxylipins. This was, however, not found in Mortierella alpina (subgenus Mortierella ). In this study we report that acetylsalicylic acid (aspirin) also targets sporangium development of Mucor circinelloides selectively, while hyphae with lower levels of mitochondrial activity are more resistant. Similar results were obtained when the anti-inflammatory compounds benzoic acid, ibuprofen, indomethacin, and salicylic acid were tested. The anti-inflammatory drugs exerted similar effects on this dimorphic fungus as found under oxygen-limited conditions. Interestingly, sporangium development of Mortierella alpina was found not to be selectively targeted by these drugs. Mortierella alpina, which could not exhibit dimorphic growth under oxygen-limited conditions, was also more sensitive to the anti-inflammatory drugs when compared with Mucor circinelloides. These results prompt further research to assess the applicability of these antimitochondrial antifungals to protect plants and animals against Mucor infections.

The effect of acetylsalicylic acid, ibuprofen, indomethacin, ketoprofen, naproxen, phenylbutazone, and salicylic acid on the microsomal oxidative drug metabolism of rat liver was studied. Pretreatment of the rats with pharmacologic doses of acetylsalicylic acid, indomethacin, and ketoprofen decreased both the demethylase and hydroxylase activities of rat liver microsomes. These effects were paralleled by decreases in microsomal cytochrome P-450 content. The rate of the microsomal reactions was increased after pretreatment with ibuprofen and naproxen but only the former increased the concentration of cytochrome P-450. Phenylbutazone and salicylic acid had no in vivo effect on the hepatic monooxygenase. The addition of 1 mM of ibuprofen, indomethacin, ketoprofen, naproxen, and phenylbutazone to rat liver microsomes inhibit both the aminopyrine N-demethylase and p-nitro-anisole O-demethylase activities. The extent of the inhibition varied between 21 and 73% of the control incubation. Indomethacin, naproxen, and phenylbutazone also decreased the aniline hydroxylase activity to roughly 60% of the control value. Acetylsalicylic acid and salicylic acid had no in vitro effect on the microsomal monooxygenase. The nonsteroidal anti-inflammatory drugs produced a reverse type I binding spectrum with oxidized cytochrome P-450; indomethacin and phenylbutazone were the strongest ligands. There is no correlation between the effect of addition of nonsteroidal anti-inflammatory drugs to the hepatic microsomal homogenate and their in vivo effect on the monooxygenase activity.

Pharmaceuticals, such as non-steroidal anti-inflammatory drugs (NSAIDs) and their metabolites, have become a major concern due to their increasing consumption and their widespread occurrence in the environment. In this paper, we investigate the occurrence of NSAIDs and their metabolites in an urban aquifer, which may serve as a potential resource for drinking water, and propose a methodology to assess the removal of these substances in the river–groundwater interface. Then, risk quotients (RQs) are computed, in order to determine the risk posed by the single NSAIDs and their mixture to human health. To this end, six NSAIDs and two metabolites were collected from an urban aquifer located in the metropolitan area of Barcelona (NE, Spain), in which the major pollution source is a contaminated river. All of the target NSAIDs were detected in groundwater samples, where the concentrations in the aquifer were higher than those found in the river water (except for ibuprofen). Diclofenac, ketoprofen, propyphenazone and salicylic acid were detected at high mean concentrations (ranging from 91.8 ng/L to 225.2 ng/L) in the aquifer. In contrast, phenazone and mefenamic acid were found at low mean concentrations (i.e., lower than 25 ng/L) in the aquifer. According to the proposed approach, the mixing of river water recharge into the aquifer seemed to some extent to promote the removal of the NSAIDs under the sub-oxic to denitrifying conditions found in the groundwater. The NSAIDs that presented higher mean removal values were 4OH diclofenac (0.8), ibuprofen (0.78), salicylic acid (0.35) and diclofenac (0.28), which are likely to be naturally attenuated under the aforementioned redox conditions. Concerning human health risk assessment, the NSAIDs detected in groundwater and their mixture do not pose any risk for all age intervals considered, as the associated RQs were all less than 0.05. Nevertheless, this value must be taken with caution, as many pharmaceuticals might occur simultaneously in the groundwater.

The aim of this review is to analyze and summarize the existing evidence regarding the possibilities of using acetylsalicylic acid (ASA) and other non-steroidal anti-inflammatory drugs (NSAIDs) to reduce cancer risk. Conclusions. Chronic inflammation facilitates the onset and progress of tumour growth. Anti-cancer properties of acetylsalicylic acid and other non-steroidal anti-inflammatory drugs are mediated via cyclooxygenase COX-dependent mechanisms, as well as other tumorigenic pathways. Current systematic review addresses potential role of ASA and other NSAIDs in reduction of cancer risk for the following localizations: head and neck, lungs, gastrointestinal tract, breast, ovaries, prostate, and skin. The role of ASA in primary prevention of colorectal cancer in specific populations is presented in 2016 U. S. Preventive Services Task Force guidelines. Studies indicate heterogeneous protective potential of ASA against different cancer types, depending on studied population, duration of intake and dose. Influence of non-aspirin NSAIDs on cancer morbidity and mortality is more controversial.

The effects of piroxicam, tenoxicam, diclofenac sodium, acetylsalicylic acid and tiaprofenic acid on the chemotaxis and random migration of human polymorphonuclear leukocytes were investigated, using zymosan-activated serum as chemo-attractant, with a modified Boyden chamber technique. All five compounds significantly reduced chemotaxis. The random migration of polymorphonuclear leukocytes was inhibited by piroxicam, diclofenac sodium and tiaprofenic acid but not by tenoxicam or acetylsalicylic acid. The inhibitory effect of these non-steroidal anti-inflammatory drugs on polymorphonuclear leukocyte chemotaxis and on random migration was generally dose-dependent. The results suggest that the drugs studied may have a direct effect on polymorphonuclear leukocyte chemotaxis and that this activity may contribute to their anti-inflammatory properties.
