The oral dosage forms are the most popular way of taking medicine although having some disadvantages like deliberate absorption and thus onset of action is extend. This can be overcome by administrating the drug in a liquid form i.e. effervescent tablet. The research is a formulation of diclofenac sodium as a effervescent tablet by wet granulation method. The bitter taste of the drug are masked by added sweetening agent (lactose, glucose etc.) In the present work we are prepared effervescent tablet in that we are used active drug diclofenac sodium and other active ingredient acid like tartaric acid and base sodium bicarbonate in different concentrations. The formulation of tablet was done by using wet granulation, wet granulation is found to be acceptable method of effervescent tablet formulation. The various pre-formulation studies was performed hardness, weight variation, disintegration, dissolution etc.

Oral dosage forms are the most popular way of taking medication, despite having some disadvantages compared with other methods like risk of slow absorption of the medicament, which can be overcome by administering the drug in liquid form, therefore, possibly allowing the use of a lower dosage. However, instability of many drugs in liquid dosage form limits its use. Effervescent technique can be used as alternate to develop a dosage form which can accelerate drug disintegration and dissolution, is usually applied in quick release preparations. Along with the development of new pharmaceutical technique, effervescent tablet are more and more extensively to adjust the behaviour of drug release, such as in sustained and controlled release preparations, pulsatile drug delivery systems, and so on. This review demonstrated the new applying of effervescent technique in effervescent tablets. Keywords: Effervescent Tablet, Sustained release, Floating Delivery System

This study has been performed to compare the compartmental modeling of two types of extravascular routes, sustained-release (SR) oral dosage forms and intramuscular (IM) injection. Twenty healthy volunteers received a single dose of 100 mg Diclofenac Sodium (DS) sustained-release tablet, then 75 mg DS Intramuscular injection after two weeks washout period. The concentrations of DS in plasma were measured using reverse-phase high-performance liquid chromatography (HPLC). The data analyzed using compartmental modeling, with single time-variant input and output. Primary kinetic parameters for both formulations, ( , , ) and other kinetic parameters were evaluated. The result shows that the IM injection needs a shorter time to reach the maximum concentration with convergent bioavailability to SR oral dosage forms, in another hand the data of IM injection fitted to single-compartment model with a correlation coefficient of 0.93 and the data of SR tablet fitted to two-compartment models with a correlation coefficient of 0.97.

Nowadays, novel fast dissolving oral films (FDF) have come in existence as an alternative dosage form in comparison with tablet, capsules, syrup and other oral dosage forms with respect to patient convenience and compliance. Fast dissolving oral films are helpful to paediatric and geriatric patients who experience difficulties in swallowing traditional oral solid-dosage forms. The FDF drug delivery systems are solid dosage form which disintegrate or dissolve within seconds when placed in the mouth cavity without need of water or chewing. FDF provide better drug dissolution, faster onset of action, bypassing the first pass metabolism of drugs and thus enhance their oral bioavailability with reduced dosing frequency. These formulations are suitable for cough, cold, sore throat, allergenic conditions, nausea, pain, hypertension and CNS disorders. The present review provides the details about the recent advancement in design and development of oral fast dissolving film.

Oral route is the most convenient route of drug administration. So far so many oral dosage forms have been developed to improve the patient compliance. The drugs with less half life are eliminated from the body with in short period of time. Different types of extended release matrix tablet have been explained briefly along with the various formulation which mainly by wet granulation or direct compression method or by dispersion of solid particle within a porous matrix formed by using different polymers. This review highlights the types of matrices, mechanisms involved and evaluation studies.  Keywords: Controlled release, matrix tablet, Polymer, Diffusion

Mouth dissolving tablets have gained more popularity among solid oral dosage forms. They perform better than conventional tablets because of its ease of administration and patient’s compliance. It facilitates water less administration and rapid onset of action. It also helps in improving oral bioavailability. The fast disintegration followed by dissolution leads to quick therapeutic activity makes these tablets superior over available tablets and capsules. Disintegration is an important key step for any solid dosage forms to show its pharmacologic effect as any solid dosage forms should disperse into its fine particles from which it is prepared. In mouth dissolving tablets superdisintegrants are incorporated in right amount for quick disintegration with improved bioavailability. Based on the source various types of superdisintegrants are available. They are synthetic, semi-synthetic, natural, and co-processed.  In this review, main emphasis is given on different types of superdisintegrants used in mouth dissolving tablets, their mechanisms and applications.

The matrix tablets of cinnarizine and nimodipine were prepared with varying ratio of Carbopol- 971P and co-excipients of varying hydrophilicity (i.e. dicalcium phosphate and spray dried lactose) by direct compression and wet granulation using alcoholic mucilage. The prepared tablets were evaluated for weight variation, hardness and friability. The influence of concentration of the matrix forming material and co-excipients on the release rate of the drug was studied. The release rate of Cinnarizine (more soluble drug) from tablets followed diffusion controlled mechanism whereas for nimodipine (less soluble drug), the drug release followed case-II or super case- II transport mechanism based on Korsmeyer- Peppas equation. The results indicated that the drug release from matrix tablets was increases with increase in hydrophilicity of drug and co-excipients. The release of drug also increased with thermal treatment and decreasing polymer concentration.
