Nano Formulation

Objective: Drug targeting is the capacity of the dosage form. In which the therapeutic agent acts specifically to desired site of action in the non-targeted tissue with the help of Nano particles is called as the drug targeting. IMATINIB is a used to treat cancer by chemo therapy. Cancers like chronic myeloid leukemia cancer (CML) and acute lymphoblastic leukemia cancer (ALL) and other specific types of gastrointestinal stromal cell tumor (GIST) systemic mast cell disease and Bone marrow failure disorder. It is administered by oral root. For ATP, Tyrosine kinase is act as a binding site. Methodology: The drug IMATINIB is loaded in the polymer chitosan, poly-(D) glucosamine is a bio compactible, bio degradable, nontoxic, antimicrobial and soluble in solvents. This preparation is done by emulsion-droplet coalescence method. Content of the Drug, Size of the particle and Zeta potential, Encapsulation efficiency and Drug release testing are described for this formulation in this study. Results: The Imatinib Nano particles were formulated and evaluated for its invitro drug release profile. Based on the invitro drug release profile of Imatinib nano particles formulation (INP1 – INP5) formulation INP3 was selected as the best formulation in which the particle size was 285.9nm. The invitro % drug release of INP3 formulation was 99.76 ± 0.82 and it was found to be the suitable formulation to manage the cancer. Conclusion: Hence it is concluded that the newly formulated controlled release nanoparticle drug delivery system of Imatinib may be idol and effective by allowing the drug to release continuously for 24 hrs.

Tablets at present, remain the most preferred oral dosage form because of many advantages they offer to formulators as well as physicians and patients. The objective of this work was to determine the effect of co-processing on the disintegration and drug-release profile of ibuprofen tablets prepared from a co-processed excipient. The co-processed excipient (CE) containing lactose, gelatin and mucin in the ratio 90:9:1 was prepared using co-fusion. The excipient was evaluated for its physicochemical properties and then used to formulate tablets with the addition of a disintegrant by direct compression. The tablets were evaluated for their tablet properties and compared with tablets prepared with cellactose- 80® (CEL) and spray dried lactose® (SDL) and a physical mix (PM) of the co-processed ingredient. Results from evaluation of CE showed that flow rate, angle of repose, Carr’s index and Hausner’s ratio were 5.28 g/sec, 20.30o, 23.75 % and 1.31, respectively. Tablets prepared with CE had friability (0%), crushing strength (5.25) KgF, disintegration time (3 mins) and T50% (2 mins). For CEL, friability (0.4 %), crushing strength (7.25) KgF, disintegration time (1 min) and T50% (2 mins); SDL, friability (1.57 %), crushing strength (7.50) KgF, disintegration time (4 mins) and T50% (2 mins) and PM, friability (2.38 %), crushing strength (5.00) KgF, disintegration time (1 min) and T50% (2 mins). In conclusion, the disintegration time and drug release profile for CE was not superior but compared favorably with CEL, SDL and PM.

The aim of this research was to develop mucoadhesive buccal patches of nicergoline by using Factorial Design of Experiment, in order to provide a sustained release of drug into the systemic circulation. A 33 factorial experimental design was employed for optimization and to study the effect of formulation variables on responses R1 (% swelling index), R2 (% drug content), R3 (mucoadhesion time) and R4 (mucoadhesion strength). In vitro drug release study was performed on the optimized formulations. All the prepared formulations had good mechanical strength, mucoadhesion strength, neutral surface pH and drug content up to 98.17%. In vitro drug release study revealed that F-5 formulation showed promising sustained drug release profile (98.21%) for over 8 h and could be a potential substitute for marketed conventional formulations. The developed formulation (F5) was found to be optimized with considerably good stability and extended drug release profile.

The float formulation is a strategy to improve the bioavailability of drugs by gastroretentive drug delivery system (GRDDS). A drug delivery model based on swellable and reswellable low density biopolymers has been designed to evaluate its drug release profile using ranitidine (RNT) as a model drug and formulations have been prepared utilizing 32factorial designs. The drug release (DR) data has been subjected to various kinetic models to investigate the DR mechanism. A reduction in rate has been observed by expanding the amounts of PSG and LSG parts, while an expansion has been noted by increasing the concentration of tragacanth (TG) and citric acid (CA) with an increment in floating time. The stearic acid (SA) has been used to decrease the lag time because a decrease in density of system was observed. The kinetic analysis showed that the optimized formulation (S4F3) followed zero-order kinetics and power law was found to be best fitted due to its minimum lag time and maximum floating ability. The resemblance of observed and predicted values indicated the validity of derived equations for evaluating the effect of independent variables while kinetic study demonstrated that the applied models are feasible for evaluating and developing float for RNT.
