LONOFLAM INJECTION

Indications

• Osteoarthritis
• Rheumatoid arthritis
• Acute pain
• Postoperative pain
• Musculoskeletal disorders

Dosage

Children: Refer to the BNF for Children for specific dosage recommendations for paediatric patients.

Adults: Refer to the BNF for specific dosage recommendations for adults, considering individual patient needs and clinical circumstances.

Mechanism of action

Lornoxicam's anti-inflammatory and analgesic activity is related to its inhibitory action on prostaglandin and thromboxane synthesis through the inhibition of both COX-1 and COX-2. This inhibition leads to a reduction in inflammation, pain, fever, and swelling, mediated by prostaglandins. However, the precise mechanism of lornoxicam has not been fully elucidated.

Pharmacodynamics

Lornoxicam is a potent inhibitor of the cyclooxygenase enzymes (COX-1 and COX-2), which catalyze the formation of prostaglandins and thromboxanes from arachidonic acid. Unlike some other NSAIDs, lornoxicam does not increase leukotriene formation, thus minimizing the risk of adverse events related to the 5-lipoxygenase pathway. Its pharmacodynamic properties allow for effective pain management and reduction of inflammation without significant increases in certain side effects.

Pharmacokinetics

Lornoxicam is absorbed well following oral administration, with peak plasma concentrations typically reached within 2 hours. It has a half-life of approximately 3 to 5 hours, allowing for dosing flexibility. Lornoxicam is metabolized in the liver primarily through conjugation with glucuronic acid. The drug is excreted mainly via the urine, with both unchanged drug and metabolites present in the excreted material.

Adverse effects

• Gastrointestinal ulceration
• Gastrointestinal bleeding
• Nausea
• Vomiting
• Dizziness
• Headache
• Rash
• Renal impairment

Interactions

• Increased risk of gastrointestinal toxicity when used with other NSAIDs or corticosteroids
• May enhance the effects of anticoagulants
• Potential for increased nephrotoxicity when combined with other renal-affecting drugs

Precautions

• Use with caution in patients with a history of peptic ulcer disease
• Monitor renal function in patients with renal impairment
• Caution in patients with cardiovascular disease due to potential fluid retention

Pregnancy

Lornoxicam should be avoided in pregnancy, especially during the third trimester, as it may affect fetal cardiovascular function and prolong gestation.

Breast-feeding

Limited data suggest that lornoxicam is excreted in breast milk; caution is advised when administering to nursing mothers.

Storage

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

Formulations

• Tablets
• Injection

Indications

• Vaccination
• Antibiotic therapy
• Hormone replacement therapy
• Enzyme replacement therapy
• Immunotherapy

Dosage

Children: Refer to specific drug information for dosing guidelines, as this varies widely based on the active ingredient and indication.

Adults: Refer to specific drug information for dosing guidelines, as this varies widely based on the active ingredient and indication.

Mechanism of action

Lyophilization itself does not have a mechanism of action, as it is a preservation technique rather than a pharmacologically active process. The mechanism of action of the lyophilized drug will depend on the specific active pharmaceutical ingredient (API) that has been lyophilized. For example, if the lyophilized drug is a vaccine, its mechanism may involve the stimulation of the immune response through the introduction of antigens.

Pharmacodynamics

The pharmacodynamics of a lyophilized drug will vary based on the specific formulation and active ingredients. Generally, once reconstituted, the pharmacodynamic properties will reflect those of the non-lyophilized form. Factors such as bioavailability, receptor binding, and the drug's effects on physiological systems will be determined by the specific drug's characteristics.

Pharmacokinetics

The pharmacokinetics of a lyophilized drug will also depend on the specific API. Once reconstituted, the drug's absorption, distribution, metabolism, and excretion (ADME) profile will align with that of the non-lyophilized version. The freeze-drying process is designed to minimize degradation, maintaining the pharmacokinetic properties of the drug post-reconstitution.

Pregnancy

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

Breast-feeding

Caution is advised when administering during breastfeeding. The effects on a nursing infant are not known.

Storage

Store in a cool, dry place. Protect from light and moisture. Follow specific storage recommendations for individual formulations.

Mechanism of action

Like other NSAIDS, lornoxicam's anti-inflammatory and analgesic activity is related to its inhibitory action on prostaglandin and thromboxane synthesis through the inhibition of both COX-1 and COX-2. This leads to the reduction of inflammation, pain, fever, and swelling, which are mediated by prostaglandins. However, the exact mechanism of lornoxicam, like that of the other NSAIDs, has not been fully determined.

Pharmacodynamics

Lornoxicam is a non-steroidal anti-inflammatory drug (NSAID) that belongs to the oxicam class. As with other NSAIDS, lornoxicam is a potent inhibitor of the cyclooxgenase enzymes, which are responsible for catalyzing the formation of prostaglandins (act as messenger molecules in the process of inflammation) and thromboxane from arachidonic acid. Unlike some NSAIDS, lornoxicam's inhibition of cyclooxygenase does not lead to an increase in leukotriene formation, meaning that arachidonic acid is not moved to the 5-lipoxygenase cascade, resulting in the minimization of the risk of adverse events.
