• Common term 1
• Clinical term 2
• Common term 2

Dosage

Children: Refer to the BNF for Children for specific paediatric dosing guidelines.

Adults: Refer to the BNF for specific adult dosing guidelines.

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

• Salmonella enteritidis infection
• Foodborne illness
• Gastroenteritis

Dosage

Children: Dosage for children should be determined based on weight and severity of symptoms. Refer to pediatric guidelines for specific dosing recommendations.

Adults: Treatment may vary based on the severity of the infection and the susceptibility of the strain to antibiotics. Refer to local guidelines for appropriate therapeutic regimens.

Mechanism of action

Salmonella enteritidis invades the intestinal epithelial cells, leading to inflammation and disruption of the intestinal barrier. It utilizes various virulence factors, including invasion proteins, to facilitate its entry into host cells and evade the host's immune response. The bacteria can also induce apoptosis in host cells, contributing to tissue damage and diarrhea.

Pharmacodynamics

Enteritidis infections provoke an immune response characterized by the activation of neutrophils and macrophages, leading to the release of pro-inflammatory cytokines. This immune response is responsible for the clinical manifestations of the infection, including fever and diarrhea. The inflammatory response can also lead to fluid secretion in the intestines, exacerbating diarrhea.

Pharmacokinetics

As a bacterial pathogen, Enteritidis does not follow traditional pharmacokinetics associated with drugs. Instead, its survival and replication depend on its ability to colonize the gastrointestinal tract and evade host immune mechanisms. Antibiotic treatment, if utilized, would depend on the sensitivity of the strain, with pharmacokinetic considerations being relevant to the chosen antimicrobial agents.

Pregnancy

Safety during pregnancy has not been established. Use only if potential benefit justifies potential risk to the fetus.

Breast-feeding

Caution is advised, as it is not known whether this drug is excreted in human milk.

Storage

Indications

• Bacterial infections
• Antibiotic-resistant infections
• Chronic infections caused by biofilm-forming bacteria
• Post-surgical infections

Dosage

Children: Refer to specific guidelines and clinical protocols for dosing recommendations, as dosage can vary based on the type of bacteriophage and the infection being treated.

Adults: Refer to specific guidelines and clinical protocols for dosing recommendations, as dosage can vary based on the type of bacteriophage and the infection being treated.

Mechanism of action

Fagotype works by utilizing bacteriophages that specifically infect and replicate within bacterial cells. Upon infection, the phage injects its genetic material into the bacterium, leading to the production of new phage particles and ultimately causing cell lysis, releasing new phages to infect adjacent bacteria. This process reduces the bacterial load and offers a targeted method of treatment.

Pharmacodynamics

The pharmacodynamics of fagotype is primarily characterized by its ability to selectively target bacterial pathogens without affecting human cells. The efficacy of phage therapy depends on the specific phage used, its ability to penetrate biofilms, and its interaction with the host immune response. Since phages can evolve alongside bacteria, they may offer a sustained therapeutic effect against bacterial infections.

Pharmacokinetics

The pharmacokinetics of fagotype can vary based on the type of bacteriophage used, the route of administration, and the infection site. Following administration, phages can be distributed throughout the body, and their half-life can be influenced by host factors such as immune response. Phages are typically cleared by the reticuloendothelial system, and repeat dosing may be necessary to maintain effective concentrations.

Pregnancy

The safety of fagotype during pregnancy has not been established. Its use should be avoided unless the potential benefits outweigh the risks.

Breast-feeding

It is not known if fagotype is excreted in human milk. Caution is advised if the drug is administered to a breastfeeding mother.

Storage

• Rabies
• Typhoid fever

Dosage

Children: Refer to specific product guidelines for paediatric dosing, as it varies by vaccine type and indication.

Adults: Refer to specific product guidelines for adult dosing, as it varies by vaccine type and indication.

Mechanism of action

Inactivated vaccines work by introducing a form of the pathogen that cannot cause disease into the body. This stimulates the immune system to produce antibodies and memory cells specific to the pathogen, allowing for a robust immune response upon future exposure. The immune system recognizes the inactivated pathogen as foreign, leading to the activation of T-cells and B-cells, which are crucial for long-term immunity.

Pharmacodynamics

The pharmacodynamics of inactivated vaccines involve the generation of an adaptive immune response. After vaccination, the body produces specific antibodies against the inactivated pathogen. The response typically includes both humoral immunity, characterized by antibody production, and cellular immunity, involving T-cell activation. The duration of immunity can vary, and booster doses may be required to maintain adequate protection.

Pharmacokinetics

Inactivated vaccines do not have a pharmacokinetic profile like traditional drugs since they do not enter systemic circulation in the same manner. Following administration, the vaccine components are taken up by antigen-presenting cells, which process and present the antigens to T-cells. The immune response is initiated locally at the site of injection and can be influenced by factors such as the route of administration and the presence of adjuvants that enhance the immune response.

Adverse effects

• Injection site reactions (pain, swelling, redness)
• Fever
• Fatigue
• Headache
• Myalgia
• Chills

Precautions

• Assess for allergies to vaccine components
• Monitor for allergic reactions post-administration
• Consider underlying health conditions that may affect immune response

Pregnancy

Inactivated vaccines are generally considered safe during pregnancy, but individual risk-benefit assessment is recommended.

Breast-feeding

Inactivated vaccines can be administered during breastfeeding without concern for adverse effects in the infant.

Storage

Store in a refrigerator at 2°C to 8°C. Do not freeze.

Formulations

• Inactivated bacterial vaccines

Indications

• Prevention of typhoid fever
• Protection during travel to endemic areas
• Vaccination of individuals at high risk of exposure

Dosage

Children: Refer to specific vaccine guidelines for administration recommendations as doses may vary based on the vaccine type and schedule.

Adults: Refer to specific vaccine guidelines for administration recommendations as doses may vary based on the vaccine type and schedule.

Mechanism of action

The inactivated Salmonella vaccine works by stimulating the immune system to produce antibodies against the Salmonella bacteria. Upon administration, the inactivated bacteria are recognized by the immune system as foreign, prompting a response that includes the production of antibodies and the activation of T-cells. This prepares the immune system to recognize and combat live Salmonella bacteria upon subsequent exposure.

Pharmacodynamics

The pharmacodynamics of inactivated Salmonella vaccines involve the induction of humoral immunity, primarily through the production of specific immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies. These antibodies target the polysaccharide antigens present on the surface of Salmonella bacteria, facilitating opsonization and clearance by phagocytic cells. The vaccine also elicits a cellular immune response, including the activation of T-helper cells, which enhance the antibody response and provide long-term immunity.

Pharmacokinetics

As an inactivated vaccine, inactivated Salmonella does not exhibit traditional pharmacokinetics such as absorption, distribution, metabolism, and excretion in the way that most drugs do. Instead, its effects are based on the immune response generated. Following vaccination, the inactivated bacteria are taken up by antigen-presenting cells, leading to an immune response that can last for years, although booster doses may be required for prolonged immunity.

Adverse effects

• Injection site reactions
• Fever
• Allergic reactions
• Headache
• Fatigue

Precautions

• Caution in individuals with weakened immune systems
• Monitor for allergic reactions in patients with a history of allergies
• Use with caution in patients with a history of febrile seizures

Pregnancy

The safety of inactivated salmonella vaccination during pregnancy has not been established. Weigh the benefits against potential risks.

Breast-feeding

It is generally considered safe to administer inactivated salmonella vaccines during breastfeeding, but consult healthcare providers for individual assessment.

Storage

Formulations

• Inactivated Salmonella Typhi vaccine
• Inactivated Salmonella Paratyphi vaccine

Indications

• Infectious diseases caused by bacteria
• Viral infections
• Fungal infections
• Parasitic infections

Dosage

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

Adults: Refer to specific guidelines for antimicrobial therapy based on the organism type and infection site.

Mechanism of action

The mechanism of action of organisms varies widely depending on the type. For example, bacteria can reproduce rapidly and may produce toxins that interfere with host cellular functions. Viruses invade host cells and hijack cellular machinery to replicate. Fungi can disrupt cell membranes and evade the immune response. Each organism has unique pathways for infection, propagation, and interaction with host defenses.

Pharmacodynamics

Pharmacodynamics of organisms relates to their growth, replication, and the effects they have on the host. Pathogenic bacteria can elicit immune responses leading to inflammation. Viruses often induce cellular apoptosis or necrosis, while fungi can cause damage through their metabolic byproducts. The interaction between the organism and the host's immune system is crucial in determining the severity of the disease.

Pharmacokinetics

Pharmacokinetics of organisms is not applicable as they do not have a pharmacokinetic profile like drugs. Instead, their behavior in the host can be characterized by their replication rate, survival in various environments, and the ability to develop resistance to antimicrobial agents. The distribution of organisms in the body, their elimination through immune responses, and their potential to establish reservoirs or persistence in host tissues are critical.

Indications

• Salmonellosis
• Gastroenteritis
• Typhoid fever
• Paratyphoid fever

Dosage

Children: Refer to appropriate guidelines based on the severity of the infection and local antimicrobial susceptibility patterns.

Adults: Refer to appropriate guidelines based on the severity of the infection and local antimicrobial susceptibility patterns.

Mechanism of action

Salmonella bacteria invade the intestinal mucosa and evade the host's immune response. They utilize a type III secretion system to inject virulence factors into host cells, facilitating their entry and promoting inflammation. This invasion disrupts normal intestinal function, leading to diarrhea, abdominal pain, and systemic symptoms.

Pharmacodynamics

The pathogenicity of Salmonella is largely attributed to its ability to adhere to and invade host epithelial cells, triggering an inflammatory response. The bacteria can survive and replicate within macrophages, allowing them to disseminate systemically. The inflammatory response contributes to the clinical manifestations of the infection, including fever and diarrhea.

Pharmacokinetics

Salmonella does not have pharmacokinetics as it is a bacterial pathogen rather than a drug. However, the course of infection can be influenced by host factors, such as immune response and the presence of underlying health conditions. Antibiotic treatment may alter the natural course of infection and influence the duration and severity of symptoms.

Adverse effects

• Diarrhea
• Fever
• Abdominal cramps
• Nausea
• Vomiting

Precautions

• Ensure proper food handling and hygiene practices to prevent infection.
• Use caution in immunocompromised patients who may be at higher risk for severe disease.

Pregnancy

Salmonella infections during pregnancy can lead to complications such as miscarriage or premature labor. Caution is advised.

Breast-feeding

Salmonella can be transmitted through contaminated breast milk, though this is rare. Mothers should be cautious about food hygiene.

Indications

• Salmonellosis
• Gastroenteritis
• Food poisoning

Dosage

Children: Refer to clinical guidelines for the management of Salmonella infections in children, which may include supportive care and antibiotic therapy tailored to the child's age and weight.

Adults: Refer to clinical guidelines for the management of Salmonella infections, including supportive care and antibiotic therapy when indicated.

Mechanism of action

Salmonella Typhimurium invades epithelial cells of the intestinal lining, using a type III secretion system to inject effector proteins that manipulate host cell functions. This invasion disrupts the host cell's cytoskeletal structure, allowing the bacteria to enter and replicate within the cells. The immune response to the infection can lead to inflammation and gastrointestinal symptoms.

Pharmacodynamics

The primary effect of Typhimurium infection is an inflammatory response in the gut, which results in diarrhea and abdominal pain. The severity of the disease can vary based on the individual's immune status and the infectious dose. The response to the bacteria involves both innate and adaptive immune mechanisms, which can lead to the clearance of the infection but may also cause complications in susceptible populations.

Pharmacokinetics

As a bacterium, Typhimurium does not have pharmacokinetic properties like traditional drugs. However, once ingested, it can survive and multiply in the gastrointestinal tract. The bacteria can then be detected in stool samples. The body responds by activating immune responses, which can include both local and systemic responses, but pharmacokinetics in the traditional sense does not apply.

Adverse effects

• Gastrointestinal disturbances
• Fever
• Abdominal pain
• Nausea
• Vomiting
• Dehydration

Precautions

• Use with caution in immunocompromised patients
• Consider hydration status in patients with gastrointestinal symptoms
• Monitor for antibiotic resistance in endemic areas
