Clinical testing is not the only way to discover drug effects on people. That is the reason controlled clinical trials are the only legal basis for central regulatory agencies in each country, such as FDA, to conclude that a new drug has clinical effectiveness for a drug or biologic. Before clinical testing begins, researchers analyze the drug’s main physical and chemical properties in the labo...

Orodispersible tablets, usually prepared using freeze-drying method, are becoming a popular drug formulation for patients who have difficulties swallowing solid dosage forms. The influence of drug solubility and concentration on the physical characteristics of lyophilized tablets composed of mannitol and gelatin was investigated. Phenobarbital and phenobarbital sodium were studied as model drug...

Purpose: To evaluate a weakly cationic exchange poly(methacrylic acid-co-divinylbenzene) resin (PMD) as a new filler-binder for direct compression tablets. Methods: Powder properties of PMD and MCC were characterized. Tablets made from PMD and MCC with and without propranolol hydrochloride were evaluated for diameter, thickness, friability, assay, disintegration, dissolution and compression beh...

OBJECTIVES To assess the efficacy of Fuhuang Tablets in treating internal hemorrhoid hemorrhage and discussing the design and quality control of clinical trials of traditional Chinese medicine.

The clinical application of sirolimus (SRL) as an immunosuppressive agent is largely hampered by its narrow therapeutic range. This study focused on developing SRL tablets with a sustained release profile for better safety. SRL was highly water insoluble and its solubility has been efficiently enhanced by preparing self-microemulsifying drug delivery system (SMEDDS). The SRL-SMEDDS was physical...

Background: Ecstasy, mainly composed of 3,4-methylenedioxymethamphetamine (MDMA), is one of the most popular addictive synthetic drugs. This study was aimed to investigate the amount of MDMA in the ecstasy tablets seized in West Azerbaijan province, northwest Iran and also to assess the relationship between the physicochemical and morphological characteristics of the tablets. Methods: MDMA cont...

BACKGROUND Provision of anti-retroviral therapy (ART) for HIV-infected children is complicated using syrup formulations, which are costlier than tablets, harder to transport and store and difficult for health-workers to prescribe and caregivers to administer. Dispersible/crushable tablets may be more appropriate. We studied the acceptability of syrups and scored tablets among young children who...

The demand for FDT (Fast Disintegrating Tablet) has been increasing from the last decade particularly in geriatric, pediatric and patient with some sort of disabilities in swallowing. FDTs are those tablets which when placed in mouth get dissolved rapidly in saliva without the need of liquid and can be swallowed. European pharmacopoeia adopted the term Orodispersible tablet for FDTs. Fast disin...

The decision criteria for the physical appearance of pharmaceutical products are subjective and qualitative means of evaluation that are based entirely on human interpretation. In this study, we have developed a comprehensive method for the quantitative analysis of the physical appearance of film coated tablets. Three different kinds of film coated tablets with considerable differences in their...
