DOI: 10.1002/smll.201100520 The effectiveness of drug delivery relies on the drug being released from its pharmaceutical dosage form, such as a tablet or capsule, and dissolving in body fl uids prior to absorption, and transport to the therapeutic target. [ 1 ] The analytical investigation of drug release from its dosage form is called dissolution testing and is essential in development as well...

The objective of a medicinal formulation development project is to deliver drug to the patient in the required amount, at the required rate, consistently within a batch, from batch to batch, and over the product’s shelf life. To produce a drug substance in a final dosage form requires pharmaceutical ingredients. In selecting excipients for pharmaceutical; dosage forms and drug products the deve...

BACKGROUND Over one hundred different pharmaceutical dosage forms have been recorded in literatures of Traditional Persian Medicine among which nasal forms are considerable. OBJECTIVES This study designed to derive the most often applied nasal dosage forms together with those brief clinical administrations. MATERIALS AND METHODS In the current study remaining pharmaceutical manuscripts of P...

There were many natural pharmaceutical dosage forms cited by Persian pharmacists and physicians in the historical pharmacopeias (Qarabadins). This work aimed to perform a comprehensive study on “Qarābādin-e-Sālehi” (1765 A.D.), one of the main Persian pharmaceutical manuscripts defining traditional dosage forms. All traditional dosage forms as well as their definitions, descri...

Film coating is an essential unit operation in tablet manufacturing. Most tablet dosage forms in the market are film coated. The main purpose for coating of immediate release film dosage form is to provide colour identification, to enhance the stability, taste masking. It is also noted that film coating can improve the processibility and handling during pharmaceutical manufacturing and is the m...

According to Process Analytical Technology perspective, drug product quality should be ensured by manufacturing process design. Initial step of the process analysis is investigation of critical process parameters (CPPs). It is generally accepted to type the CPPs based on project team knowledge and experience [5]. This paper describes the use of Design of Experiments tool for selection of the CP...

Process development organizations in modern pharmaceutical firms face the dual challenges of making clinical supplies under tight deadlines and developing a viable commercial manufacturing process at the same time. These two work processes are intertwined in complex ways, and often involve the work of many different teams. We propose a way to meet both requirements in a parallel and coordinated...

A rapid, nondestructive Raman spectroscopic method was developed for quantitative estimation of paracetamol and nimesulide in their combined dosage form. A Raman univariate calibration model was developed by measuring the peak intensities of paracetamol and nimesulide at 853 cm(-1) and 1336 cm(-1), respectively. The developed method was successfully applied for in situ, concurrent estimation of...

Cyclodextrins (CDs) have been considerably raised interest and attention in the pharmaceutical sciences due to their specific ability to form inclusion complexes with many drugs, leading to significant enhancements of the solubility, stability and bioavailability, as well as decrease in the bitterness and tissue irritation of the drugs (Carrier et al., 2007; Challa et al., 2005; Miller et al., ...
