This study was conducted to compare the bioavailability of two tablet formulations containing 200 mg Lacosamide (one Lacosamide 200 mg film-coated tablet marketed in Italy as Ollat®, one Vimpat® coated tablet). 20 healthy subjects were enrolled in a single-center, randomized, single-dose, laboratory-blinded, 2-period, 2-sequence, crossover study, with a minimum washout period of 7 days. All the 20 subjects completed the study. Plasma samples were collected up to 72.0 hours post-dosing. Lacosamide levels were determined using a validated high-performance liquid chromatography with tandem mass spectrometry (HPLC/MS/MS) method

The transdermal drug delivery system is technique that provides drug through the intact skin. Skin penetration enhancement techniques have been developed to increase the bioavailability of drug substance. These review describes various transdermal patches available in market, types of patches, basic components, polymer used in formulation. The novel drug delivery method do well and complete with those already on the market the main problem that requires consideration include device design and safety, efficacy, ease of handling and economical. Transdermal drug delivery system represent the most attractive method among these because of its low rejection rate, magnificent, ease of administration and better convenience and compliance with patient. This review article provide an overview of transdermal drug delivery system contains various innovative dosage forms. In comparison transdermal patch are effective due to its easy to apply and non-invasive.

Tepilamide fumarate (PPC-06) is a new, patented prodrug of monomethyl fumarate (MMF), belonging to the fumaric acid esters (FAEs) class of drugs. The efficacy and safety of a 400 mg PPC-06 dose administered twice daily, achieved thus far through concomitant intake of two tablets of 200 mg, was demonstrated previously in two Phase 2 clinical trials on patients with moderate to severe chronic plaque-type psoriasis.

Pregabalin is a ligand for the alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system. It has anticonvulsant, analgesic, and anxiolytic activity. The bioequivalence of a test formulation was evaluated with respect to its corresponding reference drug formulation of oral pregabalin 300 mg, administered as a capsule. This randomized-sequence, single-dose, single-blind, two-period crossover design under fasting conditions was done on 25 healthy Mexican adult subjects including both genders. There was a seven-day washout period.

The objective of this study was to evaluate the encapsulation performance of Croscarmellose sodium, a superdisintegrant in a low-dose, poor-solubility drug formulation and the in-vitro dissolution performance of the Piroxicam capsules. Preparation, characterization and evaluation of the effects of the different concentrations of carmellose sodium and the amount of dried starch on in-vitro dissolution of Piroxicam capsules. Piroxicam was chosen for its very low solubility in biological fluids, which result in poor systemic bioavailability after oral administration. Piroxicam can be categorized as Class II drugs according to the Biopharmaceutics Classification System.

The aim of this manuscript is to study cyclodextrins (CDs) as a potential excipient to suppress bitterness and enhance palatability of pediatric liquid preparations for Cetirizine, an extremely bitter drug. Natural α, β and γ CDs; and β CD derivatives such as hydroxyl propyl (HP), randomly methylated (RM) and sulfobutyl ether (SBE) β-CDs were screened in different molar ratios of 1:1, 1:2 and 1:3 for their inhibition of the extremely bitter taste of Cetirizine using the human gustatory sensation test.

The objective of this investigation was to evaluate the efficacy and safety of purified Shilajit in moderately arthritic dogs. Ten client-owned dogs in a randomized double-blinded study received either a placebo or Shilajit (500 mg) twice daily for a period of five months. Dogs were evaluated each month for physical condition (body weight, body temperature, heart rate, and respiration rate) and pain associated with arthritis (overall pain, pain from limb manipulation, and pain after physical exertion).

Capsaicin, an active ingredient of Capsicum fruit, is currently undergoing “revival” in the clinical management of pain. However, the choice of its formulation is rather limited to the use of “old-fashioned” tinctures and recently the patches. In an attempt to improve the therapeutic outcome and develop its skin-friendly formulation, we prepared the vesicle-based drug delivery system with capsaicin.
