CROMOL IV INFUSION
CROMOL IV INFUSION
Paracetamol 1000 mg Infusion (100 ml)
Cromol Iv 1000 MG Infusion{Paracetamol 1000 mg Infusion (100 ml)} is used to temporarily relieve fever and mild to moderate pain such as muscle ache, toothache, and backache. This medicine should be used with caution in patients with liver diseases due to the increased risk of severe adverse effects.
SIDE EFFECTS OF PARACETAMOL Infusion:
NAUSEA, ALLERGIC REACTIONS, SKIN RASHES, ACUTE RENAL TUBULAR NECROSIS. POTENTIALLY FATAL: VERY RARE, BLOOD DYSCRASIAS (E.G. THROMBOCYTOPENIA, LEUCOPENIA, NEUTROPENIA, AGRANULOCYTOSIS); LIVER DAMAGE.
DRUG INTERACTIONS OF PARACETAMOL Infusion:
REDUCED ABSORPTION OF CHOLESTYRAMINE WITHIN 1 HR OF ADMIN. ACCELERATED ABSORPTION WITH METOCLOPRAMIDE. DECREASED EFFECT WITH BARBITURATES, CARBAMAZEPINE, HYDANTOINS, RIFAMPICIN AND SULFINPYRAZONE. PARACETAMOL MAY INCREASE EFFECT OF WARFARIN. POTENTIALLY FATAL: PARACETAMOL INCREASES THE RISK OF LIVER DAMAGE IN CHRONIC ALCOHOLICS. INCREASED RISK OF TOXICITY WITH OTHER HEPATOTOXIC DRUGS OR DRUGS WHICH INDUCE MICROSOMAL ENZYMES E.G. BARBITURATES, CARBAMAZEPINE, HYDANTOINS, RIFAMPICIN AND SULFINPYRAZONE.
MECHANISM OF ACTION OF PARACETAMOL Infusion:
PARACETAMOL EXHIBITS ANALGESIC ACTION BY PERIPHERAL BLOCKAGE OF PAIN IMPULSE GENERATION. IT PRODUCES ANTIPYRESIS BY INHIBITING THE HYPOTHALAMIC HEAT-REGULATING CENTRE. ITS WEAK ANTI-INFLAMMATORY ACTIVITY IS RELATED TO INHIBITION OF PROSTAGLANDIN SYNTHESIS IN THE CNS. ONSET: <1 HR. DURATION: 4-6 HR. ABSORPTION: INCOMPLETE; DEPENDS UPON DOSAGE FORM. TIME TO PEAK, SERUM: ORAL: 10-60 MIN; MAY BE DELAYED IN ACUTE OVERDOSES. DECREASED RATE OF ABSORPTION WITH FOOD. DISTRIBUTION: PRESENT IN MOST BODY TISSUES; CROSSES THE PLACENTA AND ENTERS THE BREAST MILK. PROTEIN BINDING: 8-43% (AT TOXIC DOSES). METABOLISM: HEPATIC VIA GLUCURONIC AND SULPHURIC ACID CONJUGATION. AT NORMAL THERAPEUTIC LEVELS, GLUCURONIDE METABOLITES ARE METABOLISED TO REACTIVE INTERMEDIATE (ACETYLIMIDOQUINONE) WHICH IS CONJUGATED WITH GLUTATHIONE AND INACTIVATED; AT TOXIC DOSES, GLUTATHIONE CONJUGATION IS INSUFFICIENT LEADING TO INCREASED ACETYLIMIDOQUINONE WHICH MAY CAUSE HEPATIC CELL NECROSIS. EXCRETION: PLASMA HALF-LIFE: 2.7 HR (ADULTS); 1.5-2 HR (INFANTS AND CHILDREN); 3.5 HR (NEONATES). NEONATES, INFANTS AND CHILDREN UP ≤10 YR EXCRETE LESS GLUCURONIDE THAN ADULTS. HALF-LIFE MAY BE LONGER AFTER TOXIC DOSES. EXCRETED MAINLY VIA URINE (2- 5% UNCHANGED; 55% AS GLUCURONIDE METABOLITES). TOTAL BODY CLEARANCE: 18 L/HR.
