• Mumps
• Rubella
• Yellow fever
• Varicella (chickenpox)
• Rotavirus

Dosage

Children: Refer to specific vaccine guidelines for paediatric dosing.

Adults: Refer to specific vaccine guidelines for adult dosing.

Mechanism of action

Attenuated vaccines work by mimicking a natural infection. The weakened pathogen replicates in the body, stimulating the immune system to produce a response against it, which includes the activation of T-cells and the production of antibodies. This prepares the immune system to recognize and fight off the pathogen if exposed in the future.

Pharmacodynamics

The pharmacodynamics of attenuated vaccines involve the interaction of the attenuated pathogen with the host's immune system. Upon administration, the vaccine induces both humoral (antibody-mediated) and cell-mediated immunity. This leads to the development of memory cells that ensure a faster and more effective response upon subsequent exposure to the actual pathogen.

Pharmacokinetics

Attenuated vaccines are generally administered via subcutaneous or intramuscular injection. The pharmacokinetics are characterized by the distribution of the vaccine components within the body, with the attenuated organisms replicating locally and inducing an immune response. The onset of immunity typically occurs within weeks, and the duration of immunity can vary depending on the specific vaccine.

Mechanism of action

Dose acts by modulating the activity of specific neurotransmitter receptors and ion channels, influencing various physiological pathways. Its precise mechanism may involve interactions with G-protein coupled receptors, leading to downstream signaling effects that impact cellular responses.

Pharmacodynamics

Dose exhibits a range of effects depending on the dosage and target tissues. It is known to alter neurotransmitter release, affect ion conductance, and influence metabolic pathways, thereby contributing to its therapeutic efficacy and potential side effects.

Pharmacokinetics

Dose is generally absorbed following administration, with peak plasma concentrations occurring within a specified timeframe. Its distribution is influenced by tissue binding and permeability across cell membranes. The drug is metabolized primarily in the liver, with metabolites being excreted via renal and biliary routes. The half-life can vary based on individual patient factors, including age, liver function, and other concurrent medications.

Indications

• Induction of anesthesia
• Maintenance of anesthesia during surgery
• Sedation for procedures
• Pain management

Dosage

Children: Dosing in pediatric patients must be determined based on the specific agent and the child's age, weight, and clinical condition. Refer to BNF for Children for precise dosing recommendations.

Adults: Dosing varies widely based on the specific anaesthetic agent and the procedure being performed. Refer to specific guidelines or BNF for exact dosing information.

Mechanism of action

Least-acting anaesthetics primarily exert their effects by enhancing inhibitory neurotransmission, particularly through the modulation of gamma-aminobutyric acid (GABA) receptors. This results in increased chloride ion influx into neurons, leading to hyperpolarization and decreased neuronal excitability. Additionally, these agents may inhibit excitatory neurotransmitter pathways, contributing to their anesthetic effects.

Pharmacodynamics

The pharmacodynamics of least-acting anaesthetics involve a balance between sedation and analgesia, with the goal of achieving an appropriate depth of anesthesia for surgical procedures. The effects are dose-dependent, with lower doses providing sedation and higher doses leading to full anesthesia. The therapeutic window is critical, as excessive doses can lead to respiratory depression and cardiovascular instability.

Pharmacokinetics

Least-acting anaesthetics are generally characterized by rapid absorption and distribution, allowing for quick onset of action. They are metabolized primarily in the liver, with some agents undergoing hydrolysis in the plasma. The elimination half-life can vary significantly among different agents, influencing the duration of action. Factors such as age, liver function, and concurrent medications can affect the pharmacokinetics of these agents.

Pregnancy

Use during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Breast-feeding

Caution is advised; it is recommended to consult a healthcare provider before use.

Storage

• Rotavirus
• Intranasal influenza

Dosage

Children: Refer to the BNF for Children for specific dosing information based on age and vaccine type.

Adults: Refer to specific product guidelines for dosing information, as it can vary by vaccine type and brand.

Mechanism of action

Live vaccines work by introducing a weakened or attenuated form of a pathogen into the body. This stimulates the immune system to recognize and respond to the pathogen, leading to the production of antibodies and memory cells that provide long-term protection against future infections by the same pathogen.

Pharmacodynamics

The pharmacodynamics of live vaccines involve the activation of both humoral and cellular immunity. Following vaccination, the immune system generates a robust response, including the production of specific antibodies and the activation of T cells that can recognize and eliminate infected cells. This dual action helps establish long-term immunity.

Pharmacokinetics

The pharmacokinetics of live vaccines vary depending on the specific vaccine. Generally, the vaccine is administered via injection, allowing the live attenuated organisms to enter the bloodstream. The immune response typically begins within days and can last for years, depending on the vaccine. Live vaccines are usually stored under refrigeration to maintain their viability, and they should be administered within their expiration dates.

Dosage

Children: Paediatric dosing in micrograms is also highly variable based on the drug and the condition being treated. Refer to the BNF for Children for detailed dosing recommendations.

Adults: Dosage in micrograms varies widely depending on the specific medication and its indication. Consult relevant clinical guidelines or the BNF for precise dosing information.

Mechanism of action

The mechanism of action varies depending on the specific drug being measured in micrograms. For example, many drugs operate by binding to specific receptors or enzymes, leading to a physiological response. This can include agonistic or antagonistic effects on neurotransmitter systems, modulation of immune responses, or alteration of metabolic pathways.

Pharmacodynamics

Pharmacodynamics refers to the effects of the drug on the body, including the relationship between drug concentration and effect. Drugs measured in micrograms often have a steep dose-response curve, meaning small changes in dosage can lead to significant changes in therapeutic and adverse effects. The potency of such drugs is typically high, necessitating careful dosing and monitoring.

Pharmacokinetics

Pharmacokinetics involves the study of how the body absorbs, distributes, metabolizes, and excretes a drug. Drugs administered in microgram doses may exhibit rapid absorption and distribution, especially if given intravenously or sublingually. Metabolism often occurs in the liver, and excretion can be renal or via bile, depending on the drug's chemical properties. Understanding the pharmacokinetics is essential for optimizing therapeutic regimens and minimizing side effects.

Indications

• Bacterial infections
• Viral infections
• Epidemiological studies
• Antibiotic resistance monitoring

Dosage

Children: Refer to specific antimicrobial treatment guidelines based on the strain identified and the infection site.

Adults: Refer to specific antimicrobial treatment guidelines based on the strain identified and the infection site.

Mechanism of action

The mechanism of action for a strain depends on the type of microorganism it represents. For pathogenic bacteria, the strain may produce toxins, evade the host's immune response, or possess resistance mechanisms that allow it to survive in the presence of antibiotics. For viruses, strains may exhibit mutations that alter their ability to infect host cells or evade antiviral therapies.

Pharmacodynamics

Pharmacodynamics in the context of strains involves the interaction between the strain and the host's immune system, as well as the effects of specific antimicrobial agents on the strain. These interactions can influence the efficacy of treatments and the development of resistance.

Pharmacokinetics

Pharmacokinetics is not directly applicable to strains themselves but rather to the drugs used to treat infections caused by specific strains. Factors such as absorption, distribution, metabolism, and excretion of antimicrobial agents can vary depending on the strain's characteristics and the site of infection.

Pregnancy

There is limited information on the safety of strain in pregnancy. It is advisable to consult healthcare professionals for guidance.

• Herpes simplex virus infections
• Cytomegalovirus infections
• COVID-19
• Respiratory syncytial virus infections

Dosage

Children: Refer to specific antiviral agents for dosing guidance.

Adults: Refer to specific antiviral agents for dosing guidance.

Mechanism of action

Viruses infect host cells by attaching to specific receptors on the cell surface. Once inside, they hijack the host cell's machinery to replicate their genetic material and produce viral proteins. New viral particles are assembled and released from the host cell, often destroying the cell in the process. The specific mechanism can vary depending on the virus type, including integration into the host genome in retroviruses or utilizing specific pathways for replication.

Pharmacodynamics

The pharmacodynamics of antiviral agents depend on the specific virus and the mechanism of action. Antiviral drugs may inhibit viral entry into host cells, block viral replication, or prevent the assembly of new virions. The effectiveness of antiviral therapy often relates to the stage of viral replication and the immune response of the host.

Pharmacokinetics

Pharmacokinetics of antiviral drugs varies widely based on the specific medication used. Generally, antiviral agents are absorbed through the gastrointestinal tract and distributed throughout the body. They may undergo hepatic metabolism and are often excreted through the kidneys. The half-life of these drugs can range from a few hours to several days, influencing dosing schedules.
