Mechanism of action

Enzymes function by lowering the activation energy required for a chemical reaction, thus increasing the rate of the reaction. They bind to specific substrates at their active sites, forming enzyme-substrate complexes, which then undergo a transformation to produce the desired products while regenerating the enzyme for subsequent reactions.

Pharmacodynamics

The pharmacodynamic properties of enzymes are characterized by their catalytic efficiency, often described by parameters such as Km (Michaelis constant) and Vmax (maximum reaction velocity). Enzymes can be regulated through various mechanisms, including allosteric regulation, covalent modification, and feedback inhibition, allowing for precise control over metabolic pathways.

Pharmacokinetics

The pharmacokinetics of enzymes involve their absorption, distribution, metabolism, and excretion. Enzymes administered therapeutically may be subject to degradation by proteolytic enzymes in the gastrointestinal tract, influencing their bioavailability. Their distribution may vary based on the enzyme's size and solubility, and they can undergo modifications that affect their half-life and activity in the body.

Pregnancy

The safety of enzyme therapy during pregnancy varies depending on the specific enzyme. Consultation with a healthcare provider is recommended.

Breast-feeding

The transfer of enzymes into breast milk is variable. Caution is advised when administering enzyme therapy to breastfeeding mothers.

Storage

Store in a cool, dry place, away from direct sunlight and moisture. Specific storage conditions may vary based on the type of enzyme.

Dosage

Children: Refer to the specific therapeutic regimen determined by a healthcare professional, as equine therapy is individualized based on patient needs.

Adults: Refer to the specific therapeutic regimen determined by a healthcare professional, as equine therapy is individualized based on patient needs.

Mechanism of action

Equine therapy operates on several levels. The physical interaction with horses can enhance gross motor skills and encourage physical fitness. Psychologically, the bond formed between horse and human can foster emotional healing, reduce anxiety, and build confidence. The rhythmic motion of riding has been shown to have a calming effect on individuals, mimicking similar movements to those experienced in a therapeutic setting. Moreover, the social interaction involved in caring for and riding horses may improve communication skills and socialization.

Pharmacodynamics

Equine therapy itself does not involve pharmacological agents; however, it may influence the psychobiological pathways in the body. The interactions evoke hormonal responses that can alter levels of cortisol and adrenaline, enhancing relaxation and reducing stress. The therapeutic environment can also promote the release of endorphins, contributing to a sense of well-being and happiness.

Pharmacokinetics

As equine therapy does not involve drugs, pharmacokinetics is not applicable. However, the effects on the body can vary based on individual patient characteristics, the specific condition treated, and the duration and frequency of the therapy sessions. Factors such as age, physical condition, and psychological state can influence therapeutic outcomes.

Pregnancy

Equine products should be used with caution during pregnancy, as there is limited data on their safety. Consultation with a healthcare professional is recommended.

Breast-feeding

Safety during breastfeeding is not well established; therefore, caution is advised when using equine products in nursing mothers.

Storage

Store in a cool, dry place away from direct sunlight. Keep out of reach of children.

Indications

• Primary immunodeficiency disorders
• Secondary immunodeficiency disorders
• Autoimmune diseases such as Guillain-Barré syndrome and systemic lupus erythematosus
• Certain infections including hepatitis A and measles
• Prevention of hemolytic disease of the newborn

Dosage

Children: Refer to the BNF for Children for appropriate dosing information tailored to the specific needs and conditions of pediatric patients.

Adults: Refer to the BNF for specific dosing guidelines based on the condition being treated.

Mechanism of action

Immunoglobulins function by recognizing specific antigens on pathogens and forming immune complexes. This leads to neutralization of the pathogen, opsonization for enhanced phagocytosis, and activation of the complement system. Immunoglobulin G (IgG) is the most abundant and provides the majority of antibody-based immunity against invading pathogens.

Pharmacodynamics

The pharmacodynamic effects of immunoglobulin include the enhancement of opsonization and phagocytosis, neutralization of toxins and viruses, and modulation of immune responses. They can also have anti-inflammatory effects and may reduce the severity of autoimmune responses in certain conditions.

Pharmacokinetics

Immunoglobulins are administered intravenously or subcutaneously, leading to a rapid increase in serum immunoglobulin levels. The half-life of immunoglobulin varies, typically ranging from 21 to 30 days. They are distributed widely in body fluids and tissues, and are eventually metabolized by the liver and eliminated through the kidneys.

Contra-indications

• Hypersensitivity to immunoglobulin products
• Severe hyperprolinemia (for specific formulations)
• IgA deficiency with antibodies against IgA (for specific formulations)

Adverse effects

• Headache
• Fever
• Nausea
• Rash
• Myalgia
• Chills
• Anaphylactic reactions
• Thromboembolic events
• Hemolytic anemia

Interactions

• Live attenuated vaccines may be less effective when given concurrently. It is advisable to delay vaccination for at least 3 months after administration of immunoglobulin.
• Caution should be exercised when used with anticoagulants due to potential increased risk of bleeding.

Precautions

• Monitor for signs of allergic reactions, especially in patients with a history of anaphylaxis.
• Use with caution in patients with renal impairment or a history of thromboembolic events.
• Injection site reactions may occur; proper administration techniques should be employed.

Pregnancy

Immunoglobulin can be used during pregnancy when clinically indicated, as it is generally considered safe.

Breast-feeding

Immunoglobulin is excreted in human breast milk but is not known to cause any adverse effects in nursing infants.

Storage

Store between 2°C and 8°C. Do not freeze. Protect from light. Once opened, use promptly as instructed.

Formulations

• Intravenous immunoglobulin (IVIG)
• Subcutaneous immunoglobulin (SCIG)
• Intramuscular immunoglobulin (IMIG)

Indications

• Vaccination against multiple infectious diseases
• Preventive immunization in at-risk populations
• Post-exposure prophylaxis for certain infections

Dosage

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

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

Mechanism of action

Polyvalent vaccines stimulate the immune system to produce antibodies against multiple pathogen types simultaneously. By introducing a mixture of antigens, the vaccine activates both humoral and cell-mediated immunity, preparing the immune system to recognize and combat pathogens upon future exposure.

Pharmacodynamics

The pharmacodynamic effect of polyvalent vaccines involves the generation of a robust immune response. This includes the activation of B cells to produce specific antibodies, T helper cell activation to support B cell function, and the generation of memory cells for long-term immunity. The efficacy can vary based on the individual's immune status and the specific antigens included in the vaccine.

Pharmacokinetics

Polyvalent vaccines are typically administered intramuscularly or subcutaneously. After administration, the vaccine components are taken up by antigen-presenting cells, which then process the antigens and present them to T cells. The onset of immunity generally occurs within weeks as antibodies are produced and memory cells are formed. The duration of immunity varies depending on the specific antigens and the individual's response.

Pregnancy

Polyvalent vaccines may be administered during pregnancy, but the risk-benefit should be evaluated. Live vaccines are generally contraindicated.

Breast-feeding

Polyvalent vaccines can be administered during breastfeeding as they are not expected to pose a risk to the infant.
