Crystal modification A of 1-(2,6-difluorobenzyI)-1 H-1,2,3-triazole-4-carboxamide and dosage forms and formulations thereof

TL;DR: In this article, the authors proposed a novel crystal modification of the compound I-(2,6-difluorobenzyl)-I H-I,2,3-triazole-4-carboxamide, wherein crystal modification A is characterized by characteristic lines with interplanar spacings (d values) of 10.5 and 2.81.

The nanoscale characterization and interparticulate interactions of pharmaceutical materials

TL;DR: In this paper, the authors used the atomic force microscope (AFM) artefact of tip imaging to produce 3D images of particles of micronised and SEDSTM salbutamol sulphate, an anti-asthma drug, contacting a model surface of highly orientated pyrolytic graphite (HOPG).

Investigating physical properties of solid dosage forms during pharmaceutical processing : Process analytical applications of vibrational spectroscopy

Meike Römer
TL;DR: In this paper, the authors propose a method to solve the problem of "uniformity" and "uncertainty" in the context of health care, and propose a solution.
Dissertation

Investigation of the physico-chemical properties of amorphous solid-state forms of azithromycin

TL;DR: The solid-state properties of active pharmaceutical ingredients are studied to establish whether they have an application in the manufacture of drugs or in the formulation of new drugs.

Mechanism of sustained‐action medication. Theoretical analysis of rate of release of solid drugs dispersed in solid matrices

TL;DR: The analyses suggest that for the latter system the time required to release 50% of the drug would normally be expected to be approximately 10 per cent of that required to dissolve the last trace of the solid drug phase in the center of the pellet.

The united states pharmacopeia.

Robert A. Hatcher
- 04 Jan 1908 - 
TL;DR: The Pharmacopeia was called into being by physicians in 1820, and in 1850 pharmacists were admitted to the convention; since then physicians have gradually relinquished control to pharmacists, and to-day the authors are confronted with an anomalous condition.
Book

Thermal methods of analysis

TL;DR: In this article, a revised edition necessitated by the phenomenal growth of the field during the past decade contains 90% new material, focusing on tech niques and applications of thermal analysis.
