🇮🇳 critifol injection के बारे में (Hindi Summary)

उपयोग: यह दवा प्रोपोफोल नामक सक्रिय तत्व वाला एक इंजेक्शन है, जिसका उपयोग अस्पताल में विशेषज्ञ डॉक्टरों द्वारा सामान्य एनेस्थीसिया देने के लिए किया जाता है। इसका उपयोग सर्जरी से पहले रोगी को बेहोश करने, सर्जरी के दौरान बेहोशी बनाए रखने, और आईसीयू में मरीजों को शांत रखने के लिए किया जाता है। यह दवा बहुत तेजी से असर करती है और मरीज कुछ ही सेकंड में बेहोश हो जाता है। यह दवा केवल अस्पताल में ही दी जाती है और इसे घर पर कभी भी नहीं लिया जाना चाहिए।

साइड इफेक्ट्स: इस दवा के सामान्य दुष्प्रभावों में इंजेक्शन लगाने की जगह पर जलन, रक्तचाप में कमी, धीमी हृदय गति, और सांस रुकना शामिल हैं। कुछ मरीजों को उल्टी, सिरदर्द और चक्कर भी आ सकते हैं। गंभीर दुष्प्रभावों में तेजी से सांस रुकना, गंभीर निम्न रक्तचाप, और एलर्जी प्रतिक्रिया शामिल हैं। लंबे समय तक अधिक मात्रा में उपयोग से प्रोपोफोल इन्फ्यूजन सिंड्रोम हो सकता है, जो एक गंभीर स्थिति है।

सुरक्षा सलाह: यह दवा केवल योग्य एनेस्थेसियोलॉजिस्ट या गहन चिकित्सा विशेषज्ञ द्वारा ही दी जानी चाहिए। इसे अस्पताल या सर्जिकल सेंटर के बाहर कभी भी उपयोग न करें। इस दवा को लेने से पहले अपने डॉक्टर को अपनी सभी एलर्जी, विशेषकर अंडे और सोया से होने वाली एलर्जी के बारे में बताएं। इस दवा को लेने के बाद कम से कम 24 घंटे तक वाहन न चलाएं और मशीनरी न चलाएं। इस दवा के साथ शराब का सेवन बिल्कुल न करें।

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is administered intravenously, so absorption is not applicable. It enters the bloodstream directly and reaches the brain within seconds.
DistributionThis medicine is highly lipophilic and distributes rapidly from blood into well-perfused tissues such as the brain, heart, and lungs, then redistributes to less perfused tissues like muscle and fat. It crosses the blood-brain barrier quickly and also crosses the placenta.
Protein BindingApproximately 97% to 98% of this medicine is bound to plasma proteins, primarily albumin and erythrocytes.
MetabolismThis medicine undergoes extensive hepatic metabolism, mainly by glucuronidation via UDP-glucuronosyltransferase enzymes, and to a lesser extent by cytochrome P450-mediated oxidation. The metabolites are largely inactive.
Half-LifeThe initial distribution half-life is approximately 2 to 4 minutes, and the terminal elimination half-life ranges from 4 to 7 hours after prolonged infusion.
ExcretionMetabolites of this medicine are primarily excreted in the urine, with a small fraction eliminated in faeces. Less than 1% is excreted unchanged.
BioavailabilityBioavailability is 100% because this medicine is administered directly into the bloodstream via the intravenous route.
Onset of ActionLoss of consciousness typically occurs within 30 to 60 seconds after a single intravenous induction dose.
Peak Plasma TimePeak plasma concentration is achieved immediately after intravenous injection.
Duration of ActionThe duration of anaesthetic effect after a single induction dose is approximately 5 to 10 minutes, but this can be prolonged with continuous infusion or in patients with hepatic or renal impairment.

How It Works

This medicine produces its anaesthetic effect primarily by potentiating the inhibitory neurotransmitter gamma-aminobutyric acid at GABA-A receptors in the central nervous system. By enhancing chloride ion influx through the GABA-A receptor channel, it hyperpolarises neurons and reduces their excitability, leading to sedation, hypnosis, and loss of consciousness. At higher concentrations, it may also inhibit NMDA receptor-mediated excitation. The rapid onset and short duration of action are due to its high lipid solubility and rapid redistribution from the brain to peripheral tissues.

Mechanism Steps

1
Binding to GABA-A receptor: This medicine binds to a specific site on the GABA-A receptor complex in the brain.
2
Enhancement of GABA effect: It increases the affinity of GABA for its receptor and prolongs the opening of chloride channels.
3
Neuronal hyperpolarisation: Increased chloride influx hyperpolarises the neuronal membrane, making it less excitable.
4
CNS depression: Widespread neuronal inhibition leads to sedation, hypnosis, and loss of consciousness.
5
Rapid redistribution: The drug rapidly moves from the brain to other tissues, causing quick recovery after a single dose.

💡 How to Take critifol injection

Strength: This medicine is available as an intravenous emulsion in various strengths, typically 10 mg per mL in 20 mL ampoules or 50 mL vials. The exact strength is specified on the product label.

1This medicine is administered only by a qualified healthcare professional.
2It is given through an intravenous line, usually in the hand or arm.
3The dose is calculated based on your weight and medical condition.
4You will be connected to monitoring equipment throughout the procedure.
5After the procedure, you will be observed until you are fully alert.

Dosage Information

Adult DosageThe dose of this medicine must be individualised by a qualified clinician based on the indication, patient age, weight, and clinical status. For induction of anaesthesia, a typical adult dose is 1.5 to 2.5 mg per kg body weight given intravenously, but lower doses are used in elderly or debilitated patients. For maintenance, a continuous infusion of 4 to 12 mg per kg per hour is commonly used. For sedation in intensive care, doses range from 0.3 to 4 mg per kg per hour. These are general guidelines only; the exact dose must be determined by the attending anaesthesiologist.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician or pediatric anaesthesiologist for appropriate dosing.
Elderly DosageElderly patients are more sensitive to the effects of this medicine and may require lower doses. Dose reduction and slower administration are recommended. Close monitoring of vital signs is essential.
Renal ImpairmentNo specific dose adjustment is generally required for renal impairment, but caution is advised in severe renal failure. Monitor for prolonged effects.
Hepatic ImpairmentPatients with hepatic impairment may require lower doses due to reduced clearance. Dose adjustment should be based on clinical response and monitoring.
Maximum Daily DoseThe maximum daily dose is not fixed and depends on the clinical situation. For prolonged sedation, doses should be titrated to the lowest effective level, and the infusion should not exceed 4 mg per kg per hour for more than 48 hours without specialist review.
