Paracetamol + Serratiopeptidase + Tramadol

Usage

This combination medication is primarily prescribed for the symptomatic treatment of moderate to severe pain, particularly when pain is not adequately managed by non-opioid analgesics alone. Conditions it’s commonly used for include post-operative pain, dental pain, musculoskeletal pain (such as back pain, joint pain, and muscle ache), menstrual cramps, and toothache. It may also provide relief for fever associated with muscle pain.

Pharmacological Classification: Analgesic (combining non-opioid, proteolytic enzyme, and opioid mechanisms)

Mechanism of Action: This drug combines three active ingredients with different mechanisms:

• Paracetamol (Acetaminophen): Acts centrally to reduce fever and peripherally to relieve pain, potentially by inhibiting prostaglandin synthesis in the central nervous system and activating descending serotonergic pathways. It has minimal anti-inflammatory activity.

• Serratiopeptidase: A proteolytic enzyme believed to break down proteins that contribute to pain and inflammation, potentially reducing swelling by thinning mucus and other bodily fluids.

• Tramadol: A centrally acting opioid analgesic. It inhibits the reuptake of serotonin and norepinephrine, modulating pain perception in the central nervous system.

Alternate Names

• Paracetamol/Acetaminophen + Serratiopeptidase + Tramadol
• Acetaminophen + Serratiopeptidase + Tramadol Hydrochloride
• Tramadol/Paracetamol + Serratiopeptidase

How It Works

Pharmacodynamics:

• Paracetamol: Reduces fever by acting on the hypothalamic heat-regulating center and provides analgesia through central and peripheral mechanisms.
• Serratiopeptidase: Decreases inflammation and pain by breaking down bradykinin, fibrin, and other proteins involved in the inflammatory response.
• Tramadol: Binds to mu-opioid receptors in the central nervous system, inhibiting pain transmission. It also inhibits serotonin and norepinephrine reuptake, further enhancing pain relief.

Pharmacokinetics:

• Absorption: All three components are well-absorbed orally. Food may slightly delay the absorption of tramadol.
• Metabolism: Paracetamol is primarily metabolized in the liver. Tramadol is metabolized in the liver via CYP2D6 and CYP3A4 enzymes, forming active metabolites. Serratiopeptidase is presumably broken down in the gastrointestinal tract and absorbed as smaller peptides or amino acids.
• Elimination: Paracetamol and its metabolites are primarily excreted in the urine. Tramadol and its metabolites are also mainly excreted renally.

Dosage

Standard Dosage

Adults:

Initial dose is two tablets of Paracetamol 325mg/Tramadol 37.5mg/Serratiopeptidase 15mg, or one tablet of Paracetamol 650mg/Tramadol 75mg/Serratiopeptidase 30mg (if available), taken orally every 4-6 hours as needed for pain relief. The maximum daily dose is eight tablets (Paracetamol 2600mg/Tramadol 300mg/Serratiopeptidase 120mg) and should not be exceeded.

Children:

The safety and efficacy of this combination have not been established in children under 12 years of age.

Special Cases:

• Elderly Patients: Start with lower doses and monitor closely due to age-related physiological changes.
• Patients with Renal Impairment: Dosage adjustments may be necessary depending on the degree of impairment.
• Patients with Hepatic Dysfunction: Use with caution and potentially reduce the dosage due to the risk of paracetamol-induced hepatotoxicity. Tramadol dosage reduction might also be necessary.
• Patients with Comorbid Conditions: Exercise caution in patients with respiratory depression, seizures, head injury, or increased intracranial pressure.

Clinical Use Cases

Dosage in these settings should be individualized based on patient needs and under close monitoring, adhering to maximum daily limits:

• Intubation: Not typically used.
• Surgical Procedures: May be used for post-operative pain management.
• Mechanical Ventilation: Use cautiously due to the risk of respiratory depression, particularly with tramadol.
• Intensive Care Unit (ICU) Use: Dosage should be adjusted based on individual needs and monitored carefully.
• Emergency Situations: Not the first-line treatment for acute emergency situations due to potential side effects and slower onset of action.

Dosage Adjustments

Dose adjustments should be based on patient-specific factors including:

• Renal/hepatic function
• Age
• Comorbid conditions

Side Effects

Common Side Effects:

Nausea, vomiting, constipation, dizziness, drowsiness, headache, dry mouth, sweating, itching, anxiety, rash, flushing, stomach upset, weakness, blurred vision

Rare but Serious Side Effects:

Allergic reactions (rash, itching, swelling), respiratory depression, seizures, serotonin syndrome (mental status changes, autonomic instability, neuromuscular abnormalities), hepatotoxicity, addiction.

Long-Term Effects:

Potential for tolerance, dependence, and addiction with prolonged use of tramadol.

Adverse Drug Reactions (ADR):

Serotonin syndrome, anaphylaxis, hepatotoxicity, respiratory depression, seizures

Contraindications

• Hypersensitivity to any of the components
