Dosage

Adults: For cerebral edema, administer 0

Mechanism of action

Mannitol elevates blood plasma osmolality, resulting in enhanced flow of water from tissues, including the brain and cerebrospinal fluid, into interstitial fluid and plasma. This action reduces cerebral edema and intracranial pressure. As a diuretic, it increases the osmolality of glomerular filtrate, leading to increased urinary excretion of water and preventing sodium and chloride reabsorption in the renal tubules. Mannitol also facilitates the urinary excretion of toxic substances and can help in assessing renal function by measuring glomerular filtration rate (GFR).

Pharmacodynamics

Mannitol is classified as an osmotic diuretic. It is chemically similar to other sugar alcohols but has a unique ability to promote diuresis by remaining unabsorbed in the renal tubules. Its use is indicated for conditions associated with increased body fluids, such as cerebral edema and glaucoma. Mannitol may be combined with other diuretics to enhance diuretic efficacy. Inhaled formulations are used in cystic fibrosis, though they may cause bronchospasm and hemoptysis.

Pharmacokinetics

Mannitol is freely filtered by the glomeruli with less than 10% tubular reabsorption, which allows for its urinary excretion rate to serve as a measurement of GFR. It does not undergo significant metabolism and is eliminated primarily through the kidneys. The onset of action occurs within 30 to 60 minutes after intravenous administration, with effects lasting for several hours. Administration may require monitoring of renal function and fluid balance.

Mechanism of action

Bortezomib is a reversible inhibitor of the 26S proteasome, which is a multimeric protease complex responsible for degrading ubiquitin-tagged proteins. This inhibition prevents the breakdown of pro-apoptotic factors and cell cycle regulators, leading to increased apoptosis and cell cycle arrest in cancer cells. Bortezomib binds specifically to the active site of the β5-subunit of the proteasome, and also affects the β1 and β1i subunits, which contributes to its anticancer activity.

Pharmacodynamics

Bortezomib targets the ubiquitin-proteasome pathway, which is often dysregulated in cancer. By inhibiting proteasome activity, bortezomib increases the intracellular levels of pro-apoptotic proteins and disrupts signaling pathways that promote cancer cell survival. Studies have shown that bortezomib exerts cytotoxic effects on various cancer cell types in vitro and significantly delays tumor growth in vivo. Its effects on proteasome activity can be observed within one hour of administration, with over 75% inhibition noted in whole blood samples.

Pharmacokinetics

Bortezomib is administered either intravenously or subcutaneously. It has a plasma half-life of approximately 40 hours, and its pharmacokinetics can be influenced by various factors including the method of administration and patient-specific characteristics. Dose adjustments may be necessary in cases of hepatic impairment. The drug is primarily eliminated through proteolytic degradation rather than hepatic metabolism, which is important for patients with liver dysfunction.

Adults: Refer to specific drug guidelines for adult dosing, as it varies widely depending on the medication and clinical condition.

Mechanism of action

The mechanism of action of injected drugs varies widely based on the specific medication being administered. Generally, injected drugs enter the bloodstream directly, allowing them to circulate rapidly throughout the body. For instance, antibiotics may work by inhibiting bacterial cell wall synthesis, while analgesics may modulate pain pathways in the central nervous system. Each drug has unique pathways through which it achieves its therapeutic effects.

Pharmacodynamics

Pharmacodynamics refers to the effects of drugs on the body and their mechanisms of action. For injectable medications, effects can be immediate or delayed, depending on the drug's formulation and route of administration. Factors influencing pharmacodynamics include receptor affinity, drug concentration, and the presence of other substances that may enhance or inhibit the drug's effects. For example, some injectable drugs may require specific receptors to exert their effects, while others may have a broader range of action.

Pharmacokinetics

Pharmacokinetics involves the absorption, distribution, metabolism, and excretion (ADME) of injected drugs. After administration, drugs are rapidly absorbed into the bloodstream, leading to quick therapeutic effects. The distribution depends on factors such as blood flow, tissue permeability, and protein binding. Drugs are metabolized primarily in the liver and excreted through the kidneys or bile. The pharmacokinetic profile can vary widely based on the drug's chemical nature, dosage, and individual patient factors.

Pregnancy

Safety during pregnancy depends on the specific injection and its active ingredients. It is essential to consult a healthcare professional for guidance.

Breast-feeding

The safety of injections during breastfeeding varies by the specific medication. It is recommended to seek advice from a healthcare provider.

Indications

• Major depressive disorder
• Generalized anxiety disorder
• Schizophrenia
• Bipolar disorder
• Obsessive-compulsive disorder

Dosage

Children: Refer to the BNF for Children for specific dosing guidelines, as pediatric dosages are often calculated based on weight and the specific condition being treated.

Adults: Refer to specific prescribing information for individual tertiary drugs, as dosing can vary widely based on the compound and patient characteristics.

Mechanism of action

Tertiary compounds, particularly tertiary amines, often act as antagonists or modulators of neurotransmitter receptors in the central nervous system. They may inhibit reuptake of neurotransmitters like serotonin, norepinephrine, and dopamine, enhancing their availability in the synaptic cleft. This modulation can lead to altered mood, cognition, and perception, which is beneficial in treating conditions such as depression and schizophrenia.

Pharmacodynamics

The pharmacodynamic effects of tertiary compounds can vary widely depending on the specific drug. Generally, they exhibit a range of effects including sedation, anxiolytic activity, and mood elevation. Due to their ability to interact with multiple receptor types, including adrenergic, muscarinic, and histaminergic receptors, they may also produce side effects such as sedation, anticholinergic effects, and weight gain.

Pharmacokinetics

Tertiary compounds are usually well-absorbed following oral administration, with peak plasma concentrations occurring within a few hours. They are extensively metabolized in the liver, primarily through cytochrome P450 enzymes, leading to various active and inactive metabolites. The elimination half-lives can vary, influencing dosing schedules. They are typically excreted in urine, and their pharmacokinetic profiles can be affected by factors such as age, liver function, and potential drug interactions.

Pregnancy

The safety of tertiary medications during pregnancy varies. Consult specific drug references for individual agents.

Breast-feeding

Consult specific drug references for individual agents regarding use during breastfeeding.

Storage

Mechanism of action

Ethanol affects the brain’s neurons in several ways. It alters their membranes as well as their ion channels, enzymes, and receptors. Alcohol also binds directly to the receptors for acetylcholine, serotonin, GABA, and the NMDA receptors for glutamate. The sedative effects of ethanol are mediated through binding to GABA receptors and glycine receptors (alpha 1 and alpha 2 subunits). It also inhibits NMDA receptor functioning. In its role as an anti-infective, ethanol acts as an osmolyte or dehydrating agent that disrupts the osmotic balance across cell membranes. ... Ethanol is known to affect a large number of membrane proteins that participate in signaling pathways such as neurotransmitter receptors, enzymes, and ion channels, and there is extensive evidence that ethanol interacts with a variety of neurotransmitters. The major actions of ethanol involve enhancing the inhibitory effects of gamma-aminobutyric acid (GABA) at GABAa receptors and blockade of the N-methyl-D-aspartate (NMDA) subtype of glutamate, an excitatory amine acid (EAA) receptor. Animal studies indicate that the acute effects of ethanol result from competitive inhibition of glycine binding to NMDA receptor and disruption of glutamatergic neurotransmission by inhibiting the response of the NMDA receptor. Persistent glycine antagonism and attenuation of glutamatergic neurotransmission by chronic ethanol exposure results in tolerance to ethanol by enhancing EAA neurotransmission and NMDA receptor upregulation. The latter appears to involve selective increases in NMDA R2B subunit concentrations and other molecular changes in specific brain loci. The abrupt withdrawal of ethanol thus produces a hyperexcitable state that leads to the ethanol withdrawal syndrome and excitotoxic neuronal death. GABA-mediated inhibition, which normally acts to limit excitation, is eliminated during ethanol withdrawal syndrome and further intensifies this excitation. In addition, NMDA receptors function to inhibit the release of dopamine in the nucleus accumbens and mesolimbic structures, which modulate the reinforcing action of addictive xenobiotics such as ethanol. By inhibiting NMDA receptor activity, ethanol could increase dopamine release from the nucleus accumbens and ventral tegmental area and could thus create dependence. Chronic ethanol administration also results in tolerance, dependence, and an ethanol withdrawal syndrome, mediated, in part, by desensitization and or downregulation of GABAa receptors. The development of alcoholic ketoacidosis (AKA) requires that a combination of physical and physiologic events occur. The normal response to starvation and depletion of hepatic glycogen stores is for amino acids to be converted to pyruvate. Pyruvate can serve as a substrate for gluconeogenesis, be converted to acetyl-CoA, which can enter the Krebs cycle or can be utilized in various biosynthetic pathways (eg, fatty acid, ketone bodies, cholesterol, and acetylcholine) ... Ethanol metabolism generates NADH, resulting in an excess of reducing potential. This high redox state favors the conversion of pyruvate to lactate, diverting pyruvate from being a substrate for gluconeogenesis. To compensate for the lack of normal metabolic substrates, the body mobilizes fat from adipose tissue and increased fatty acid metabolism as an alternative source of energy. This response is mediated by a decrease in insulin and an increased secretion of glucagon, catecholamines, growth hormone, and cortisol. Fatty acid metabolism results in the formation of acetyl-CoA and it combines with the excess acetate that is generated from ethanol metabolism to form acetoacetate. Most of the acetoacetate is reduced to beta-hydroxybutyrate due to the excess reducing potential or high redox state of the cell. Volume depletion interferes with the renal elimination of acetoacetate and beta-hydroxybutyrate, and contributes to the acidosis. An elevated lactate concentration may result from shunting from pyruvate or

Pharmacodynamics

Alcohol produces injury to cells by dehydration and precipitation of the cytoplasm or protoplasm. This accounts for its bacteriocidal and antifungal action. When alcohol is injected in close proximity to nerve tissues, it produces neuritis and nerve degeneration (neurolysis). Ninety to 98% of ethanol that enters the body is completely oxidized. Ethanol is also used as a cosolvent to dissolve many insoluble drugs and to serve as a mild sedative in some medicinal formulations. Ethanol also binds to GABA, glycine, NMDA receptors and modulates their effects. Ethanol is also metabolised by the hepatic enzyme alcohol dehydrogenase.

Mechanism of action

The ubiquitin-proteasome pathway is a homeostatic proteolytic pathway for intracellular protein degradation: proteins marked with a poly-ubiquitin chain are degraded to small peptides and free ubiquitin by the proteasome, which is a large multimeric protease. Aberrant proteasome-dependent proteolysis, as seen in some malignancies, can lead to uncontrolled cell division, leading to tumorigenesis, cancer growth, and spread. Bortezomib is a reversible inhibitor of the 26S proteasome, which is made up of a 20S core complexed with a 19S regulatory complex. Individual β-subunits allow specific catalytic action of the 20S core. In mammalian cells, bortezomib is a potent inhibitor of the proteasome’s chymotryptic-like activity, which is attributed to the β5-subunit of the 20S core particle. Bortezomib binds to the active site of the threonine hydroxyl group in the β5-subunit. A probing study showed bortezomib also binding to and inhibiting the β1-subunit, which mediates the caspase-like activity of the proteasome, and β1i-subunit, which is an altered subunit that is expressed to form immunoproteasomes in response to cell stress or inflammation. By inhibiting the proteasome-mediated degradation of key proteins that promote cell apoptosis, bortezomib induces a cell cycle arrest during the G2-M phase. It is believed that multiple mechanisms, other than proteasome inhibition, may be involved in the anticancer activity of bortezomib. The anticancer activity of bortezomib was largely associated with suppression of the NF-κB signalling pathway, resulting in the downregulation of anti-apoptotic target genes and expression of anti-apoptic proteins. This may be explained by bortezomib preventing uncontrolled degradation of IκB, which is an inhibitory protein of NF-κB. NOXA, which is a pro-apoptotic factor, induced by bortezomib selectively in cancer cells; thus, it is suggested to be another key mechanism of bortezomib. Bortezomib, a modified dipeptidyl boronic acid, is an antineoplastic agent. The drug reversibly inhibits the 26S proteasome, a large protein complex that degrades ubiquitinated proteins. The ubiquitin-proteasome pathway plays an essential role in regulating the intracellular concentration of specific proteins, thereby maintaining homeostasis within cells. Inhibition of the 26S proteasome by bortezomib prevents targeted proteolysis and causes disruption of normal homeostatic mechanisms, which can lead to cell death. In vitro studies indicate that bortezomib is cytotoxic to a variety of cancer cell types. Bortezomib has been shown to cause a delay in tumor growth in vivo in tumor models, including multiple myeloma. ... The mechanisms underlying /bortezomib/ cancer cell toxicity are complex. A growing body of evidence suggests proteasome inhibition-dependent regulation of the BCL-2 family is a critical requirement. In particular, the stabilization of BH3-only proteins BIK, NOXA and BIM, appear to be essential for effecting BAX- and BAK-dependent cell death. ... Proteasome inhibition is a novel, targeted approach in cancer therapy. Both natural and synthetic proteasome inhibitors selectively penetrate cancer cells, disrupting the orderly destruction of key regulatory proteins involved in tumorigenesis and metastasis. Disrupting the orderly destruction of regulatory proteins causes an imbalance of these proteins within the cell, which interferes with the systematic activation of signaling pathways required to maintain tumor cell growth and survival; therefore, cellular replication is inhibited and apoptosis ensues. ... Bortezomib (PS-341, Velcade) is a potent and selective inhibitor of the proteasome that is currently under investigation for the treatment of solid malignancies. /Investigators/ have shown previously that bortezomib has activity in pancreatic cancer models and that the drug induces endoplasmic reticulum (ER) stress but also suppresses the unfolded protein response (UPR). Because the UPR is an important cytoprotective

Pharmacodynamics

Bortezomib works to target the ubiquitin-proteasome pathway, an essential molecular pathway that regulates intracellular concentrations of proteins and promotes protein degradation. The ubiquitin-proteasome pathway is often dysregulated in pathological conditions, leading to aberrant pathway signalling and the formation of malignant cells. In one study, patient-derived chronic lymphocytic leukemia (CLL) cells contained 3-fold higher levels of chymotrypsin-like proteasome activity than normal lymphocytes. By reversibly inhibiting proteasome, bortezomib prevents proteasome-mediated proteolysis. Bortezomib exerts a cytotoxic effect on various cancer cell types _in vitro_ and delays tumour growth _in vivo_ in nonclinical tumour models. Bortezomib inhibits the proteasome activity in a dose-dependent manner. In one pharmacodynamic study, more than 75% of proteasome inhibition was observed in whole blood samples within one hour after dosing of bortezomib.

Mechanism of action

Mannitol is an osmotic diuretic that is metabolically inert in humans and occurs naturally, as a sugar or sugar alcohol, in fruits and vegetables. Mannitol elevates blood plasma osmolality, resulting in enhanced flow of water from tissues, including the brain and cerebrospinal fluid, into interstitial fluid and plasma. As a result, cerebral edema, elevated intracranial pressure, and cerebrospinal fluid volume and pressure may be reduced. As a diurectic mannitol induces diuresis because it is not reabsorbed in the renal tubule, thereby increasing the osmolality of the glomerular filtrate, facilitating excretion of water, and inhibiting the renal tubular reabsorption of sodium, chloride, and other solutes. Mannitol promotes the urinary excretion of toxic materials and protects against nephrotoxicity by preventing the concentration of toxic substances in the tubular fluid. As an Antiglaucoma agent mannitol levates blood plasma osmolarity, resulting in enhanced flow of water from the eye into plasma and a consequent reduction in intraocular pressure. As a renal function diagnostic aid mannitol is freely filtered by the glomeruli with less than 10% tubular reabsorption. Therefore, its urinary excretion rate may serve as a measurement of glomerular filtration rate (GFR). The exact mechanism of action of inhaled mannitol in the symptomatic maintenance treatment of cystic fibrosis remains unclear. It is hypothesized that mannitol produces an osmotic gradient across the airway epithelium that draws fluid into the extracellular space and alters the properties of the airway surface mucus layer, allowing easier mucociliary clearance. MANNITOL IS.../USED/ IN PROPHYLAXIS OF ACUTE RENAL FAILURE. IT IS USED FOR THIS PURPOSE IN CONDITIONS AS DIVERSE AS CARDIOVASCULAR OPERATIONS, SEVERE TRAUMATIC INJURY, OPERATIONS IN THE PRESENCE OF SEVERE JAUNDICE, AND MGMNT OF HEMOLYTIC TRANSFUSION REACTIONS. IN EACH OF THESE CONDITIONS, A PRECIPITOUS FALL IN THE FLOW OF URINE MAY BE ANTICIPATED EITHER AS THE RESULT OF AN ACUTELY REDUCED FILTRATION RATE OR FROM ACUTE CHANGES IN TUBULAR PERMEABILITY. THE LATTER MAY BE CONSEQUENCE OF THE PRESENCE OF NOXIOUS AGENT WITHIN THE TUBULAR FLUID IN EXCESSIVELY HIGH CONCN, IN SOME INSTANCES SUFFICIENT TO RESULT IN ACTUAL PRECIPITATION. IN THESE SITUATIONS, MANNITOL EXERTS OSMOTIC EFFECT WITHIN THE TUBULAR FLUID, INHIBITS WATER REABSORPTION, & MAINTAINS THE RATE OF URINE FLOW. ...CONCN OF TOXIC AGENT WITHIN TUBULAR FLUID DOES NOT REACH EXCESSIVELY HIGH LEVELS THAT OTHERWISE WOULD HAVE BEEN ACHIEVED BY MORE COMPLETE REABSORPTION OF WATER. ...EVEN THOUGH /GLOMERULAR/ FILTRATION RATE IS REDUCED, MANNITOL IS STILL FILTERED @ GLOMERULUS. THE TUBULAR IMPERMEABILITY TO MANNITOL IS NOT ALTERED BY ACUTE RENAL ISCHEMIA OF SHORT DURATION. HENCE, THE MANNITOL THAT IS FILTERED IS ALSO EXCRETED IN THE VOIDED URINE. UNREABSORBED SOLUTE LIMITS BACK DIFFUSION OF WATER. ...URINE VOL CAN BE MAINTAINED EVEN IN PRESENCE OF DECR GLOMERULAR FILTRATION.

Pharmacodynamics

Chemically, mannitol is an alcohol and a sugar, or a polyol; it is similar to xylitol or sorbitol. However, mannitol has a tendency to lose a hydrogen ion in aqueous solutions, which causes the solution to become acidic. For this reason, it is not uncommon to add a substance to adjust its pH, such as sodium bicarbonate. Mannitol is commonly used to increase urine production (diuretic). It is also used to treat or prevent medical conditions that are caused by an increase in body fluids/water (e.g., cerebral edema, glaucoma, kidney failure). Mannitol is frequently given along with other diuretics (e.g., furosemide, chlorothiazide) and/or IV fluid replacement. Inhaled mannitol has the possibility to cause bronchospasm and hemoptysis; the occurrence of either should lead to discontinuation of inhaled mannitol.
