🇮🇳 rimactazid plus e 450 mg/300 mg/800 mg tablet के बारे में (Hindi Summary)

उपयोग: यह दवा रिफैम्पिसिन और आइसोनियाजिड का संयोजन है, जिसका उपयोग तपेदिक (टीबी) के इलाज के लिए किया जाता है। यह टीबी के बैक्टीरिया को मारती है और संक्रमण को फैलने से रोकती है। यह दवा आमतौर पर खाली पेट, एक बार प्रतिदिन ली जाती है, और पूरे कोर्स को पूरा करना बहुत जरूरी है।

साइड इफेक्ट्स: इस दवा के सामान्य दुष्प्रभावों में मतली, उल्टी, पेट में असुविधा, भूख न लगना, और सिरदर्द शामिल हैं। रिफैम्पिसिन के कारण पेशाब, पसीना और आंसू नारंगी-लाल रंग के हो सकते हैं, जो हानिरहित है। गंभीर दुष्प्रभावों में यकृत की सूजन, एलर्जी, और खून की कमी शामिल हैं। अगर आंखों या त्वचा का रंग पीला पड़े, गहरे रंग का पेशाब आए, या असामान्य थकान हो, तो तुरंत डॉक्टर से मिलें।

सुरक्षा सलाह: इस दवा को डॉक्टर के निर्देशानुसार ही लें, हर दिन एक ही समय पर, खाली पेट। बीच में दवा बंद न करें, चाहे आप बेहतर महसूस करें, क्योंकि इससे दवा प्रतिरोधी टीबी हो सकती है। शराब का सेवन बिल्कुल न करें। यकृत और गुर्दे की बीमारी, मधुमेह, या शराब की लत हो तो डॉक्टर को बताएं। नियमित रूप से लिवर फंक्शन टेस्ट कराएं। गर्भनिरोधक गोलियों का असर कम हो सकता है, इसलिए अतिरिक्त उपाय अपनाएं।

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionRifampicin is well absorbed from the gastrointestinal tract, with peak plasma concentrations reached 2 to 4 hours after oral administration. Isoniazid is also rapidly absorbed, with peak levels occurring 1 to 2 hours after ingestion. Food may delay absorption slightly, but the overall extent is not significantly reduced. This medicine is intended for oral use.

DistributionRifampicin is highly lipophilic and distributes widely into body tissues and fluids, including cerebrospinal fluid, lungs, liver, and urine. It is about 80% protein-bound. Isoniazid distributes throughout body fluids and tissues, including cerebrospinal fluid, and is about 10% to 15% protein-bound. Both drugs cross the placenta and are excreted in breast milk.

Protein BindingRifampicin is approximately 80% bound to plasma proteins. Isoniazid is approximately 10% to 15% bound to plasma proteins.

MetabolismRifampicin is metabolized in the liver, primarily by deacetylation, to an active metabolite, desacetylrifampicin. Isoniazid is metabolized in the liver by acetylation, with the rate determined by genetic polymorphism (fast and slow acetylators). Both drugs can induce hepatic enzymes.

Half-LifeThe elimination half-life of rifampicin is approximately 3 to 4 hours, but it may shorten with repeated dosing due to autoinduction. The half-life of isoniazid is about 1 to 4 hours, depending on acetylator status.

ExcretionRifampicin and its metabolites are excreted mainly in bile and urine. Isoniazid and its metabolites are excreted primarily in urine. Dose adjustment may be needed in severe renal impairment.

BioavailabilityRifampicin has a bioavailability of about 90% to 95% when taken on an empty stomach. Isoniazid bioavailability is approximately 90%.

Onset of ActionThe onset of bactericidal action begins within hours of the first dose, but clinical improvement in tuberculosis symptoms may take several weeks.

Peak Plasma TimeRifampicin peak plasma concentration occurs 2 to 4 hours after oral administration. Isoniazid peak plasma concentration occurs 1 to 2 hours after oral administration.

Duration of ActionThe bactericidal effect persists for 24 hours or more, allowing once-daily dosing. However, the full treatment course lasts for months.

How It Works

This medicine combines two antitubercular agents with complementary mechanisms. Rifampicin inhibits bacterial DNA-dependent RNA polymerase, blocking RNA synthesis and leading to bacterial death. Isoniazid is a prodrug activated by bacterial catalase-peroxidase and then inhibits mycolic acid synthesis, disrupting the mycobacterial cell wall. Together, they target both actively dividing and slowly replicating Mycobacterium tuberculosis, reducing the risk of resistance.

Mechanism Steps

1

Rifampicin uptake and RNA polymerase binding: Rifampicin enters the bacterial cell and binds to the beta subunit of DNA-dependent RNA polymerase, forming a stable complex that prevents RNA chain elongation.

2

Inhibition of RNA synthesis: By blocking RNA synthesis, rifampicin prevents the production of essential proteins, leading to bacterial death.

3

Isoniazid activation: Isoniazid is activated by the mycobacterial catalase-peroxidase enzyme KatG into a reactive species that inhibits InhA.

4

Inhibition of mycolic acid synthesis: Activated isoniazid blocks the synthesis of mycolic acid, a key component of the mycobacterial cell wall, causing cell lysis and death.

5

Synergistic bactericidal effect: The dual attack on RNA and cell wall synthesis results in enhanced killing of Mycobacterium tuberculosis and reduces the likelihood of resistant mutants emerging.
