Adults: Refer to specific treatment guidelines or BNF for dosing recommendations based on the severity of the condition and the type of medication used.

Mechanism of action

In bronchitis, the inflammation leads to hypersecretion of mucus and bronchoconstriction. Treatment often includes bronchodilators to relax airway muscles and anti-inflammatory agents to reduce swelling. In cases of bacterial bronchitis, antibiotics may be used to target the offending pathogens.

Pharmacodynamics

The pharmacodynamics of drugs used in bronchitis focus on reducing inflammation and bronchoconstriction, facilitating easier breathing. Bronchodilators work by stimulating beta-adrenergic receptors to induce bronchodilation, while corticosteroids reduce inflammatory responses in the airways.

Pharmacokinetics

The pharmacokinetics of drugs prescribed for bronchitis vary. For example, bronchodilators are rapidly absorbed and act within minutes, while corticosteroids may take longer to exert their full effects. The distribution of these drugs occurs systemically, with metabolism primarily in the liver and excretion through urine.

Dosage

Children: Refer to specific medications used to treat the particular disease for dosing information.

Adults: Refer to specific medications used to treat the particular disease for dosing information.

Mechanism of action

The mechanism of action varies significantly depending on the specific disease in question. For infectious diseases, pathogens may interact with host cells, leading to inflammation, immune response activation, or tissue damage. Chronic diseases often involve complex interactions between genetic factors, lifestyle choices, and environmental influences. For example, in autoimmune diseases, the immune system mistakenly targets healthy cells, leading to inflammation and tissue destruction.

Pharmacodynamics

Pharmacodynamics of disease involves understanding how the disease state affects physiological functions and the body's response to treatment. In infectious diseases, the presence of pathogens can lead to altered immune responses, while chronic diseases may involve changes in metabolic pathways, hormonal balances, or cellular functions. Medications targeting disease processes aim to restore normal function, alleviate symptoms, or eradicate pathogens.

Pharmacokinetics

Pharmacokinetics is not applicable to the term 'disease' as it refers to the movement of drugs within the body, including absorption, distribution, metabolism, and excretion of specific medications used to treat diseases. Each medication will have its own pharmacokinetic profile depending on its chemical properties and the disease being treated.

Adults: Refer to appropriate antimicrobial guidelines and specific drug BNF entries for dosing.

Mechanism of action

Antimicrobial agents function through various mechanisms depending on their class. Bactericidal agents kill bacteria directly, while bacteriostatic agents inhibit bacterial growth. Common mechanisms include inhibition of cell wall synthesis (e.g., penicillins), disruption of nucleic acid synthesis (e.g., fluoroquinolones), interference with protein synthesis (e.g., aminoglycosides), and alteration of cell membrane permeability (e.g., polymyxins). Antiviral agents may inhibit viral entry, replication, or assembly. Antifungal agents disrupt fungal cell membranes or inhibit synthesis of essential components like ergosterol.

Pharmacodynamics

Antimicrobial agents exhibit concentration-dependent or time-dependent killing effects. Their efficacy can be influenced by the site of infection, the immune response of the host, and the presence of resistant strains. The minimum inhibitory concentration (MIC) is a critical parameter that helps determine the appropriate dosing regimen for effective treatment. Adverse effects can include toxicity to host cells, disruption of normal flora, and allergic reactions.

Pharmacokinetics

Pharmacokinetics of antimicrobial agents encompass absorption, distribution, metabolism, and excretion (ADME). Most antibiotics are absorbed in the gastrointestinal tract, though some may require intravenous administration for systemic infections. Distribution varies, with some agents achieving higher concentrations in certain tissues or fluids (e.g., cerebrospinal fluid, lung tissue). Metabolism often occurs in the liver, with various pathways leading to active or inactive metabolites. Renal excretion is common, necessitating dose adjustments in patients with renal impairment.

Adults: Refer to specific treatment protocols or clinical guidelines for dosages, as they may vary based on the context of use.

Mechanism of action

Newcastle disease virus exerts its effects primarily through the induction of apoptosis in infected cells and the activation of the host immune system. The virus binds to specific receptors on the surface of host cells, facilitating viral entry and replication. It leads to the release of pro-inflammatory cytokines and enhances the anti-tumor immune response in the context of oncolytic therapies.

Pharmacodynamics

The pharmacodynamics of Newcastle disease virus involves its ability to replicate in tumor cells, leading to cell lysis and release of viral progeny that can further infect and destroy adjacent tumor cells. The host's immune system is subsequently activated, enhancing the overall anti-tumor response.

Pharmacokinetics

The pharmacokinetics of Newcastle disease virus is complex, as it involves viral replication and dissemination within the host. Following administration, the virus replicates at the site of infection, with peak viral loads observed at various time points depending on the route of administration and the host's immune status. The virus is typically cleared by the immune system over time, although its persistence can vary based on the type of host cells infected.

Pregnancy

Safety in pregnancy has not been established. Use with caution and only if the potential benefit justifies the potential risk to the fetus.

Breast-feeding

Safety during breastfeeding is not well established. Caution is advised.

Storage

Store in a cool, dry place away from direct sunlight and heat. Follow specific storage requirements if available.

Mechanism of action

Reovirus exerts its effects primarily through its ability to selectively infect and replicate in cancer cells that have activated Ras signaling pathways. Upon infection, reovirus enters the host cell, where it uses the host's cellular machinery to replicate its RNA genome and produce viral proteins. This replication leads to cell lysis and death, releasing new virions that can infect adjacent tumor cells. Additionally, reovirus activates the host immune system, promoting a broader antitumor immune response.

Pharmacodynamics

Reovirus demonstrates selective cytotoxicity toward tumor cells, particularly those with mutations in RAS genes. The virus triggers apoptotic pathways and engages immune mediators, enhancing the body's ability to recognize and eliminate malignant cells. The immunogenic nature of reovirus also facilitates the activation of dendritic cells and T cells, fostering an adaptive immune response against the tumor.

Pharmacokinetics

The pharmacokinetics of reovirus can vary based on the route of administration and the type of tumor being treated. Upon administration, the virus disseminates throughout the body, but its distribution is often limited by the immune response. The half-life and clearance rate are influenced by the host's immune system and the presence of antibodies against the virus. It is vital to monitor the viral load and immune response to assess therapeutic effectiveness.

Pregnancy

Limited data are available on reovirus use in pregnancy. It is recommended to consider the potential benefits against risks.

Breast-feeding

Data on reovirus excretion in human milk are lacking. Caution is advised when administering to breastfeeding women.

Storage

Reovirus should be stored according to specific manufacturer guidelines, typically at 2-8 degrees Celsius. Avoid freeze-thaw cycles.
