Livocard-Plus

Adults

Acute Coronary Syndrome (ACS): Loading dose of Clopidogrel 300 mg (or 600 mg for PCI) followed by 75 mg once daily, in combination with Aspirin 75-150 mg once daily. For established atherothrombotic disease (MI, stroke, PAD): 75 mg Clopidogrel once daily in combination with Aspirin 75 mg once daily.

Elderly

No specific dose adjustment is generally required for elderly patients.

Renal_impairment

Caution is advised in patients with severe renal impairment due to limited experience. No dose adjustment is generally required for mild to moderate impairment.

Onset

Clopidogrel: 2 hours to 7 days for full effect. Aspirin: Within 1 hour for antiplatelet effect.

Excretion

Clopidogrel and its metabolites are excreted in urine (approx 50%) and feces (approx 48%). Aspirin and its metabolites are primarily excreted renally.

Half life

Clopidogrel (active metabolite): approx 8 hours. Aspirin (acetylsalicylic acid): 15-20 minutes; salicylic acid (metabolite): 2-4 hours.

Absorption

Clopidogrel is rapidly absorbed from the gastrointestinal tract, but undergoes extensive first-pass metabolism. Aspirin is rapidly and completely absorbed from the GI tract.

Metabolism

Clopidogrel is a prodrug, metabolized to its active thiol metabolite primarily by CYP2C19. Aspirin is rapidly hydrolyzed to salicylic acid by esterases in the GI mucosa, liver, and blood.

SSRIs/SNRIs

Increased risk of bleeding.

Thrombolytics

Increased risk of bleeding.

NSAIDs (e.g., Ibuprofen, Naproxen)

Increased risk of gastrointestinal bleeding due to synergistic effect with Aspirin.

Oral Anticoagulants (e.g., Warfarin)

Increased risk of bleeding due to combined antithrombotic effects.

Proton Pump Inhibitors (PPIs) (e.g., Omeprazole, Esomeprazole)

Concomitant use with Clopidogrel may reduce its antiplatelet effect by inhibiting CYP2C19. Avoid concomitant use.
