Die "sublinguale Verabreichung von Medikamenten" beinhaltet traditionell die systemische Verabreichung ber die Schleimhaut des Mundbodens oder die ventrale Oberfl che der Zunge. Die sublinguale Schleimhaut ist aufgrund der lipoiden Beschaffenheit der Schleimhaut mit einer reichen Vaskulatur relativ durchl ssig, was eine schnelle Absorption erm glicht und eine akzeptable Bioverf gbarkeit aufweist. Es ist bequem, erleichtert die einfache Verabreichung und seine F higkeit, den hepatischen First-Pass zu umgehen. Diese Forschung erarbeitet ber die Entwicklung Sublingual" Tabletten von ISBD NT(Isosorbiddinitrat). Im Vergleich zu allen "Formulierungen zeigte ISDN4 eine hohe" prozentuale "Wirkstofffreisetzung, d.h. 97,15 % "in 8 min, so dass es als beste Formulierung angesehen wird, die Pullulan als Super-Desintegrat in der Konzentration von 10 mg enth lt".

La consegna sublinguale di farmaci tradizionalmente" comporta la somministrazione sistemica attraverso la membrana mucosa del pavimento della bocca o la superficie ventrale della lingua. La mucosa sublinguale relativamente permeabile a causa della natura lipoidale della membrana mucosa con una ricca vascolarizzazione, che permette un rapido assorbimento e ha una biodisponibilit accettabile. conveniente, facilita la facilit di somministrazione e la sua capacit di bypassare il primo passaggio epatico. Questa ricerca elaborare circa lo sviluppo Sublingual" compresse di ISBD NT (Isosorbide dinitrato). Rispetto a tutte le "formulazioni ISDN4 ha mostrato un alto" % "rilascio della droga cio , 97,15 % "in 8 min quindi considerato come migliore formulazione che contiene Pullulan come super disintegrato nella concentrazione di 10 mg".

L'administration sublinguale de m dicaments implique traditionnellement une administration syst mique par la muqueuse du plancher buccal ou la surface ventrale de la langue. La muqueuse sublinguale est relativement perm able en raison de la nature lipo dique de la muqueuse et de sa riche vascularisation, ce qui permet une absorption rapide et une biodisponibilit acceptable. Elle est pratique, facilite l'administration et sa capacit contourner le premier passage h patique. Cette recherche porte sur le d veloppement de comprim s sublinguaux de dinitrate d'isosorbide NT (ISBD). Compar toutes les formulations, ISDN4 a montr un pourcentage lev de lib ration du m dicament, c'est- -dire 97,15 % en 8 minutes, et est donc consid r comme la meilleure formulation qui contient du Pullulan sous forme de super-d sint gr la concentration de 10 mg.

A "administra o de drogas sublinguais tradicionalmente" envolve a administra o sist mica atrav s da membrana mucosa do assoalho da boca ou da superf cie ventral da l ngua.

Esta pesquisa elabora sobre o desenvolvimento de comprimidos "sublingual" de ISBD NT(dinitrato de isossorbida). Comparado a todas as "formula es ISDN4 mostrou alta" % de "libera o de drogas, ou seja, 97,15% "em 8 minutos, portanto considerado como a melhor formula o que cont m Pullulan como super desintegrador na concentra o de 10 mg".

Podjęzykowe podawanie lek w tradycyjnie" polega na podawaniu og lnoustrojowym przez blonę śluzową dna jamy ustnej lub brzuszną powierzchnię języka. Blona śluzowa podjęzykowa jest stosunkowo przepuszczalna ze względu na lipoidalną naturę blony śluzowej z bogatym unaczynieniem, co umożliwia szybkie wchlanianie i ma akceptowalną biodostępnośc. Jest to wygodne, ulatwia latwośc podawania i jego zdolnośc do ominięcia wątroby pierwszego przejścia. Niniejsze badania dotyczą opracowania "podjęzykowych" tabletek ISBD NT (dinitrat izosorbidu). W por wnaniu do wszystkich "preparat w ISDN4 wykazal wysoki" % "uwalniania leku, tj. 97,15 % "w ciągu 8 minut, więc jest uważany za najlepszy preparat, kt ry zawiera Pullulan jako super disintegrate w stężeniu 10 mg".

Oral route of drug administration is the most important method of administering drugs for systemic effects. Nevertheless, it is probable that at least 90% of all drugs used to produce systemic effects are administered by oral route. Drugs that are administered orally, solid oral dosage forms represent the preferred class of product. Whereas, tablets may be defined as the solid unit dosage form of medicament or medicaments with or without suitable diluents and prepared either by molding or by compression. Tablets are a unit dosage form, and they offer the greatest capabilities of all oral dosage forms for dose precision and the least content variability. They also lend themselves to certain special-release profile products, such as Sustained, Controlled, Enteric or Delayed-release products. Keeping all this in view, the present practical handbook has been written with two clear objectives, viz., (i) to enable upcoming Pharmacists i.e. Postgraduate and Undergraduate Pharmacy students, in developing and evaluating Tablet dosage forms; and (ii) to make them familiar with the art of using different Polymers, excipients, methods and techniques for the preparation of tablet dosage forms.

Sublingual drug delivery traditionally" involves systemic administration via mucosal membrane of floor of mouth or the ventral surface of tongue. The sublingual mucosa is relatively permeable due to the lipoidal nature of mucous membrane with a rich vasculature, which allows rapid absorption and has acceptable bioavailability. It is convenient, facilitates ease of administration and its ability to bypass hepatic first pass. This research elaborate about development Sublingual" tablets of ISBD NT(Isosorbide dinitrate). Compared to all "formulations ISDN4 showed high" % "drug release i.e., 97.15 % "in 8 min so it is considered as best formulation which contains Pullulan as super disintegrate in the concentration of 10 mg".

High performance liquid chromatography is at present one of the most sophisticated tool of the analysis. The estimation of Thiocolchicoside and Lornoxicam was done by RP-HPLC. The Phosphate buffer was pH 3.0 and the mobile phase was optimized with consists of Methanol: Phosphate buffer mixed in the ratio of 70:30 % v/ v. Inertsil C18 column C18 (4.6 x 150mm, 5μm) or equivalent chemically bonded to porous silica particles was used as stationary phase. The detection was carried out using UV detector at 260 nm. The solutions were chromatographed at a constant flow rate of 0.8 ml/min. the linearity range of Thiocolchicoside and Lornoxicam were found to be from 100-500 μg/ml of Thiocolchicoside and 1-5μg/ml of Lornoxicam . Linear regression coefficient was not more than 0.999. The values of % RSD are less than 2% indicating accuracy and precision of the method. The percentage recovery varies from 98-102% of Thiocolchicoside and Lornoxicam . LOD and LOQ were found to be within limit. The results obtained on the validation parameters met ICH and USP requirements .it inferred the method found to be simple, accurate, precise and linear. The method was found to be having suitable application.
