Syntrexa 5 mg

Indications

• Type 2 diabetes mellitus as monotherapy or in combination with insulin or other antidiabetic drugs
• Chronic heart failure with reduced ejection fraction
• Chronic kidney disease

Dosage

Children: Refer to the BNF for Children for specific dosing information

Adults: 10 mg once daily, with caution advised in renal impairment (avoid initiation if eGFR less than 30 mL/min/1.73 m2).

Mechanism of action

Dapagliflozin inhibits the sodium-glucose cotransporter 2 (SGLT2) located in the proximal tubule of the nephron, leading to decreased glucose reabsorption and increased urinary glucose excretion. This mechanism contributes to better glycemic control in patients with type 2 diabetes mellitus.

Pharmacodynamics

Dapagliflozin reduces sodium reabsorption, increasing sodium delivery to the distal tubule, which may decrease both pre- and afterload on the heart. This results in downregulation of sympathetic activity and reduced intraglomerular pressure, mediated by increased tubuloglomerular feedback. Clinical studies have shown that doses of dapagliflozin lead to significant urinary glucose excretion, with near-maximum effects observed at higher doses.

Pharmacokinetics

Dapagliflozin is rapidly absorbed after oral administration, with peak plasma concentrations occurring within 1 to 2 hours. It has a half-life of approximately 12.9 hours. The drug undergoes extensive metabolism primarily via UGT1A9 and UGT2B7, with renal excretion of metabolites. The pharmacokinetics may be affected by renal function, with caution advised if the estimated glomerular filtration rate (eGFR) is less than 60 mL/min/1.73 m2.

Mechanism of action

Cellulose acts primarily as a bulk-forming laxative. It absorbs water in the intestines, which increases stool bulk and stimulates peristalsis, thus facilitating bowel movements. Additionally, cellulose is not digestible by human enzymes, leading to fermentation by gut bacteria, which may enhance gut health and alter gut microbiota composition.

Pharmacodynamics

Cellulose increases stool weight and frequency of bowel movements. It works by retaining water in the intestines, leading to softer stools and improved passage through the gastrointestinal tract. The bulking effect of cellulose can help alleviate constipation and promote overall digestive health. It may also play a role in cholesterol reduction and glycemic control through its effects on digestion and absorption of nutrients.

Pharmacokinetics

Cellulose is not absorbed into the bloodstream due to its indigestible nature. Instead, it passes through the gastrointestinal tract, where it adds bulk to the stool. Its fermentation by colonic bacteria produces short-chain fatty acids, which may have beneficial effects on colon health. The onset of action for cellulose as a laxative can vary but is generally within 24 to 72 hours after ingestion.

Adverse effects

• Bloating
• Flatulence
• Diarrhea
• Abdominal discomfort

Precautions

• Use with caution in patients with a history of gastrointestinal disorders.

Mechanism of action

The mechanism of action of coatings primarily involves the modification of drug release profiles. By altering the solubility and permeability of the drug through the coating material, the release rate can be controlled. For example, enteric coatings prevent drug dissolution in the acidic environment of the stomach, allowing the drug to be released in the more neutral pH of the intestine.

Pharmacodynamics

Pharmacodynamics of coated formulations can vary significantly based on the type of coating used. Immediate-release coatings dissolve quickly, leading to rapid absorption and onset of action. Controlled-release coatings are designed to dissolve slowly over time, providing a sustained release of the drug, which can lead to prolonged therapeutic effects and reduced dosing frequency. The choice of coating material and thickness influences the overall pharmacodynamic profile of the drug.

Pharmacokinetics

The pharmacokinetics of coated drugs are influenced by the coating material and the drug itself. Factors such as the rate of dissolution, absorption site, and first-pass metabolism play critical roles. Coatings can alter the bioavailability and distribution of the drug. For example, enteric coatings can enhance the absorption of drugs that are unstable in acidic conditions, potentially increasing their bioavailability when the drug reaches the intestine.

Mechanism of action

Copovidone acts primarily as a binder in solid dosage forms. It forms a cohesive gel in the presence of moisture, which helps in the agglomeration of powder particles, thus improving the mechanical strength and integrity of tablets. Additionally, copovidone can enhance drug solubility and dissolution rate, thereby facilitating better absorption of active pharmaceutical ingredients.

Pharmacodynamics

As a polymer, copovidone does not exert a pharmacological effect in the traditional sense but plays a crucial role in the pharmaceutical formulation process. It aids in the uniform distribution of active ingredients and can enhance the stability of formulations, thereby ensuring consistent therapeutic efficacy. Its properties allow for the sustained release of drugs when used in controlled-release formulations.

Pharmacokinetics

Copovidone is not absorbed in the gastrointestinal tract and therefore does not exhibit systemic pharmacokinetics. Instead, it remains in the gastrointestinal lumen, where it can affect the release and absorption of other co-administered drugs. Its degradation products are typically non-toxic and are excreted without causing harm to the body.

Formulations

• Oral tablets
• Capsules
• Topical ointments

Indications

• Monitoring respiratory function
• Assessment of metabolic status
• Management of respiratory acidosis
• Management of respiratory alkalosis

Dosage

Children: Dosing for interventions related to carbon dioxide levels in pediatric patients should be guided by clinical protocols and the BNF for Children.

Adults: Dosing for interventions related to carbon dioxide levels is typically based on clinical assessment and individual patient needs. Refer to clinical guidelines for specific scenarios.

Mechanism of action

Carbon dioxide acts primarily as a signaling molecule in the body, influencing respiratory drive and blood pH. It is produced during cellular respiration and is a critical component of the bicarbonate buffering system, which helps maintain acid-base homeostasis. Elevated levels of CO2 in the blood stimulate ventilation in the lungs, increasing the rate of gas exchange and facilitating the removal of excess CO2.

Pharmacodynamics

The pharmacodynamic effects of dioxides, particularly carbon dioxide, are closely related to its concentration in the blood. As CO2 levels increase, it leads to respiratory acidosis, which can stimulate the respiratory centers in the brain to increase ventilation. Conversely, low levels of CO2 can cause respiratory alkalosis, potentially leading to decreased respiratory drive. CO2 also plays a role in vasodilation and can affect blood flow and pressure through its influence on smooth muscle tone.

Pharmacokinetics

Carbon dioxide is produced endogenously during metabolic processes and is transported in the bloodstream primarily in three forms: dissolved in plasma, as bicarbonate ions (HCO3-), and bound to hemoglobin. The half-life of CO2 in the bloodstream is very short due to its rapid exchange with alveolar gas in the lungs. The elimination of CO2 occurs through exhalation, making it a dynamic component of respiratory physiology.

Pregnancy

Data on the effects of dioxide during pregnancy are limited. Caution is advised due to potential risks associated with exposure.

Breast-feeding

Limited data are available regarding the excretion of dioxide in human milk. Caution is recommended.

Storage

Adults: Refer to specific BNF guidelines for the medication contained within the film formulation, as dosing will vary widely based on the active ingredient.

Mechanism of action

The mechanism of action for drugs delivered via film formulations varies depending on the active pharmaceutical ingredient contained within the film. Generally, the drug is absorbed through the mucosal membranes in the mouth or gastrointestinal tract, leading to systemic circulation. This can enhance the onset of action compared to traditional solid dosage forms.

Pharmacodynamics

Pharmacodynamics will vary based on the specific drug contained in the film formulation. In general, pharmacodynamics refers to the biochemical and physiological effects of the drug on the body, including its mechanism of action, therapeutic effects, and side effects. Film formulations may provide rapid onset of action due to faster dissolution and absorption of the drug.

Pharmacokinetics

Pharmacokinetics, which includes absorption, distribution, metabolism, and excretion (ADME), will also vary by the specific active ingredient in the film formulation. In general, films may exhibit faster absorption rates due to their design, leading to quicker peak plasma concentrations. The distribution will depend on the lipophilicity of the drug, while metabolism will occur primarily in the liver, and excretion can be renal or fecal, depending on the drug's characteristics.

Indications

• Lactose intolerance
• As a filler or excipient in pharmaceutical formulations

Dosage

Children: Refer to the BNF for Children for specific dosing information based on age and clinical context.

Adults: Refer to the BNF for specific dosing information based on clinical context.

Mechanism of action

Lactose is metabolized in the intestine by the enzyme lactase into its constituent monosaccharides, glucose and galactose. In individuals with lactase deficiency, unabsorbed lactose passes into the colon, where it is fermented by bacteria, leading to gas production and osmotic effects that contribute to diarrhea.

Pharmacodynamics

The pharmacodynamics of lactose are primarily related to its effects on gastrointestinal function. In healthy individuals, lactose is effectively broken down into glucose and galactose, which are absorbed and utilized for energy. In individuals with lactose intolerance, the unabsorbed lactose can cause osmotic diarrhea and colonic fermentation, leading to discomfort and symptoms associated with lactose intolerance.

Pharmacokinetics

Lactose is not absorbed in the gastrointestinal tract until it is hydrolyzed into glucose and galactose by lactase. The absorption of glucose and galactose occurs in the small intestine. The half-life is not applicable as lactose is not typically administered as a medication but is rather ingested as a natural component of food. Its metabolism primarily occurs in the intestine.

Adverse effects

• Bloating
• Diarrhea
• Abdominal pain
• Flatulence

Precautions

• Use with caution in patients with lactose intolerance.
• Consider potential for gastrointestinal upset in sensitive individuals.

For example, antibiotics may inhibit bacterial cell wall synthesis, while analgesics may block pain receptors in the central nervous system.

Pharmacodynamics

The pharmacodynamics of systemic drugs depend on their specific class and mechanism of action. Generally, systemic drugs are intended to provide widespread effects across the body, which can lead to both therapeutic effects and potential side effects. The efficacy of these drugs is often measured by their ability to achieve desired plasma concentrations that correlate with clinical outcomes.

Pharmacokinetics

Pharmacokinetics of systemic medications involves absorption, distribution, metabolism, and excretion (ADME). After administration, systemic drugs are absorbed into the bloodstream, distributed to various tissues, metabolized by the liver or other organs, and then excreted, primarily through the kidneys. The half-life and clearance rates can vary significantly depending on the drug's chemical properties and the patient's physiology.

Pregnancy

Consult with a healthcare professional before use, as safety in pregnancy has not been established for all drugs.

Breast-feeding

Consult with a healthcare professional before use, as some drugs may pass into breast milk.

Storage

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

Mechanism of action

Dapagliflozin inhibits the sodium-glucose cotransporter 2(SGLT2) which is primarily located in the proximal tubule of the nephron. SGLT2 facilitates 90% of glucose reabsorption in the kidneys and so its inhibition allows for glucose to be excreted in the urine. This excretion allows for better glycemic control and potentially weight loss in patients with type 2 diabetes mellitus.

Pharmacodynamics

Dapagliflozin also reduces sodium reabsorption and increases the delivery of sodium to the distal tubule. This may influence several physiological functions including, but not restricted to, lowering both pre- and afterload of the heart and downregulation of sympathetic activity, and decreased intraglomerular pressure which is believed to be mediated by increased tubuloglomerular feedback. Increases in the amount of glucose excreted in the urine were observed in healthy subjects and in patients with type 2 diabetes mellitus following the administration of dapagliflozin. Dapagliflozin doses of 5 or 10 mg per day in patients with type 2 diabetes mellitus for 12 weeks resulted in excretion of approximately 70 grams of glucose in the urine per day at Week 12. A near-maximum glucose excretion was observed at the dapagliflozin daily dose of 20 mg. This urinary glucose excretion with dapagliflozin also results in increases in urinary volume. After discontinuation of dapagliflozin, on average, the elevation in urinary glucose excretion approaches baseline by about 3 days for the 10 mg dose. Dapagliflozin was not associated with clinically meaningful prolongation of QTc interval at daily doses up to 150 mg (15 times the recommended maximum dose) in a study of healthy subjects. In addition, no clinically meaningful effect on QTc interval was observed following single doses of up to 500 mg (50 times the recommended maximum dose) of dapagliflozin in healthy subjects.
