Цена: 7653.00 р.

The aim of current study was to investigate the in-vitro performance of compress coated tablet of Atenolol. Administration of conventional tablet has been reported to exhibit fluctuation in the plasma drug level, resulting either in manifestation of side effect or reduction in drug concentration at the receptor site. Atenolol has strong absorption throughout GIT as well as in colon. But, it causes GI irritation problem. Hence it is always effective to have absorption of Atenolol at Colon site. A novel colon targeted tablet formulation was developed by press coating rapidly disintegrating tablet of Atenolol with HPMC K100M, guar gum and Eudragit S-100 as barrier layer. The device was enteric coated so that variability in gastric emptying time can be overcome and a colon specific release can be achieved.

Novel Drug Delivery System
Цена: 4747.00 р.

The design of an controlled drug delivery system should be primarily aimed at achieving more predictable and increased bioavailability of drugs. Over the years, novel dosage forms have become increasingly sophisticated with major role being played by controlled release drug delivery systems. Such systems release drug at predetermined rate, as determined by drug pharmacokinetics and desired therapeutic concentration. It is evident from the recent scientific and patent literature that an increased interest in novel dosage forms that are retained in the body for a prolonged and predictable period of time exists today in academic and industrial research groups. One of the most feasible approaches for achieving a prolonged and predictable drug delivery profile in the GI tract is to control the gastric residence time (GRT). Dosage forms with a prolonged GRT, i.e. gastro-retentive dosage forms (GRDFs), provide new and important therapeutic options

Poloxamers are nonionic triblock copolymers composed of a central hydrophobic chain of polyoxypropylene flanked by two hydrophilic chains of polyoxyethylene. Now a day, Poloxamer are widely used in different drug delivery systems due to its biodegradability, high solubility and low toxicity. Poloxamers contain both hydrophilic and hydrophobic part, so they are used widely as surfactant and emulsifier in the formulation. Poloxamer are used in solid dispersion as solubility enhancer. Pluronic grade has thermo reversible gelation property, liquid at room temperature and convert gel at body temperature, so it is used in the control release formulation. Poloxamer are used for improve the stability of Nanoparticle and liposome. Poloxamers are used in solid suppositories for improve the dissolution of poorly soluble drugs and decrease the rectal irritation compare to conventional polymer like polyethylene glycol. Poloxamer are also used in the biological preparation as stabilizer.

Metronidazole Floating Microspheres
Цена: 5715.00 р.

Gastroretentive systems can remain in the gastric region for several hours and hence significantly prolong the gastric residence time of drugs. Prolonged gastric retention improves bioavailability, reduces drug waste, and improves solubility for drugs that are less soluble in a high pH environment. Floating microspheres are especially effective in delivery of sparingly soluble and insoluble drugs. It is known that as the solubility of a drug decreases, the time available for drug dissolution becomes less adequate and thus the transit time becomes a significant factor affecting drug absorption. For weakly basic drugs that are poorly soluble at an alkaline pH, hollow microspheres may avoid chance for solubility to become the rate-limiting step in release by restricting such drugs to the stomach.

Pharmaceutical Drug Analysis by Atomic Absorption Spectroscopy
Цена: 3572.00 р.

Naproxen and ibuprofen (aryl propionic acid derivatives) both are classified as non-steroidal anti-inflammatory agents. Except HPLC, no sensitive methods were reported for both the drugs. HPLC methods suffer from two drawbacks- first; requirement of costly chemicals and second; more time consuming. Because atomic absorption spectroscopy (AAS) methods are simple, sensitive, rapid, reproducible and uses low cost chemicals. The objective of present research work was to develop highly sensitive and economical analytical methods for the quantitative estimation of naproxen and ibuprofen in pharmaceutical formulations by AAS. The methods were based on the reaction of naproxen and ibuprofen with copper and cobalt chloride to form coloured metal complexes. These complexes were extracted with organic solvents and digested with acids. Naproxen and ibuprofen were indirectly estimated by AAS via the determination of the copper and cobalt content in the formed complexes. The proposed methods may be...
