Lornoxicam – Medical Description

Generic Name: Lornoxicam

Pharmacological Class

Nonsteroidal Anti-inflammatory Drug (NSAID)
Oxicam derivative

Description

Lornoxicam is a potent nonsteroidal anti-inflammatory drug (NSAID) with analgesic, anti-inflammatory, and antipyretic properties. It is used for the short-term and long-term management of acute and chronic pain associated with musculoskeletal disorders, inflammatory arthritis, postoperative pain, and other painful conditions.

Lornoxicam inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, thereby decreasing inflammation, pain, and fever. Compared with other oxicams, lornoxicam has a relatively short elimination half-life (approximately 3–5 hours), which may contribute to less prolonged drug exposure while maintaining effective analgesia.

Available Pharmaceutical Forms

Lornoxicam is available in several dosage forms depending on the country and manufacturer:

• Film-coated tablets
• Orally dispersible tablets (ODT)
• Powder for solution for intravenous (IV) injection
• Powder for solution for intramuscular (IM) injection

Mechanism of Action

Lornoxicam inhibits both cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes, reducing the production of prostaglandins responsible for:

• Pain
• Inflammation
• Fever

It also modulates inflammatory pathways involved in acute and chronic pain without possessing opioid activity.

Indications

Lornoxicam is indicated for the symptomatic treatment of:

Acute Pain

• Acute musculoskeletal pain
• Dental pain
• Postoperative pain
• Trauma-related pain
• Acute low back pain

Chronic Inflammatory Disorders

• Osteoarthritis
• Rheumatoid arthritis
• Ankylosing spondylitis
• Other inflammatory musculoskeletal disorders

Injectable formulations are commonly used when rapid analgesia or temporary inability to take oral medication exists.

Benefits

Lornoxicam may help:

• Relieve mild to severe pain
• Reduce inflammation
• Improve joint mobility
• Decrease morning stiffness
• Reduce postoperative analgesic requirements
• Improve physical function in inflammatory arthritis

Clinical studies have shown analgesic efficacy comparable to several commonly used NSAIDs in appropriate clinical settings.

Recommended Dosage

Dosage should always be individualized according to clinical condition and patient risk factors.

1. Film-Coated Tablets / Orally Dispersible Tablets

Adults

• 4–8 mg orally
• Two to three times daily
• Maximum daily dose: 16 mg

For chronic inflammatory diseases:

• Usually 8–12 mg/day
• Maximum 16 mg/day

Take with water. Orally dispersible tablets should dissolve on the tongue before swallowing.

2. Intravenous Injection (IV)

Adults

• 8 mg IV
• May repeat after 12 hours if clinically indicated
• Maximum 16 mg/day

3. Intramuscular Injection (IM)

Adults

• 8 mg IM
• Repeat only if required
• Maximum 16 mg/day

Injectable therapy is generally intended for short-term use, after which patients should transition to oral therapy when appropriate.

Administration

Oral Tablets

• Swallow whole with water.
• May be taken with food to reduce gastrointestinal irritation, although absorption may be slightly delayed.

Orally Dispersible Tablets

• Allow the tablet to dissolve on the tongue before swallowing.
• Water is optional unless otherwise directed.

Injection

• Administer only by qualified healthcare professionals.
• IV administration should be given slowly according to institutional protocols.
• IM injection should be administered deeply into a large muscle.

Common Side Effects

Most adverse effects are dose-dependent and typical of NSAIDs.

Common adverse reactions include:

• Nausea
• Dyspepsia
• Abdominal pain
• Diarrhea
• Constipation
• Headache
• Dizziness
• Fatigue
• Vomiting
• Elevated liver enzymes

Serious Adverse Effects

Although uncommon, serious adverse events may occur:

• Gastrointestinal ulceration
• Gastrointestinal bleeding or perforation
• Severe allergic reactions
• Bronchospasm in susceptible patients
• Acute kidney injury
• Hepatic dysfunction
• Severe skin reactions (Stevens–Johnson syndrome, toxic epidermal necrolysis)
• Increased risk of thrombotic cardiovascular events (e.g., myocardial infarction and stroke), particularly with prolonged use or high doses, a class warning applicable to NSAIDs.

Contraindications

Lornoxicam is contraindicated in patients with:

• Hypersensitivity to lornoxicam or other NSAIDs
• History of NSAID-induced asthma, urticaria, or allergic reactions
• Active peptic ulcer disease
• Active gastrointestinal bleeding
• Severe heart failure
• Severe hepatic impairment
• Severe renal impairment unless specifically supervised
• Third trimester of pregnancy

Drug Interactions

Use caution with:

• Other NSAIDs
• Aspirin
• Anticoagulants (e.g., warfarin)
• Antiplatelet agents
• Corticosteroids
• SSRIs and SNRIs
• ACE inhibitors
• ARBs
• Diuretics
• Methotrexate
• Lithium
• Cyclosporine
• Tacrolimus

Patients with reduced CYP2C9 activity may have increased exposure to lornoxicam, and pharmacogenetic guidelines recommend considering dose adjustments in poor metabolizers.

Use in Special Populations

Elderly

Older adults have an increased risk of gastrointestinal bleeding, renal impairment, and cardiovascular adverse events. The lowest effective dose for the shortest duration is recommended.

Pregnancy

• Avoid during the third trimester due to the risk of premature closure of the fetal ductus arteriosus and other fetal complications.
• NSAIDs should generally be avoided after approximately 20 weeks of gestation unless specifically advised by a healthcare professional.

Breastfeeding

Clinical data during lactation are limited. An alternative medication may be preferred, particularly when nursing newborn or preterm infants.

Pediatrics

Safety and efficacy in children have not been firmly established; routine pediatric use is generally not recommended.

Storage

Tablets / ODT

• Store at 20–25°C (68–77°F).
• Protect from moisture and excessive heat.

Injection

• Store according to manufacturer recommendations.
• Use reconstituted solutions promptly or within the validated stability period.

Patient Counseling

Patients should be advised to:

• Take the lowest effective dose for the shortest duration necessary.
• Avoid taking more than one NSAID at the same time unless directed by a healthcare provider.
• Take oral doses with food if stomach upset occurs.
• Stay adequately hydrated.
• Report black stools, vomiting blood, severe abdominal pain, chest pain, shortness of breath, sudden weakness, or severe skin reactions immediately.
• Inform healthcare providers about all prescription, over-the-counter, and herbal medicines they are taking.
