摘要:
Agonist compounds of the histamine H.sub.3 receptor for therapeutic use, pharmaceutical compositions acting as agonists of the said receptor and preparation process are disclosed.The compounds are derived from an amine R-NH.sub.2 having a high affinity for the histamine H.sub.3 receptor and to the primary amine function of which a group which gives rise to a bond that is capable of being slowly hydrolyzed in a neutral medium is attached. The pharmaceutical compositions contain these compounds and a pharmaceutically acceptable vehicle or excipient.These compounds are used for producing a medicinal product which inhibits the synthesis and the release of histamine, in particular, possessing sedative, sleep-regulating, anticonvulsant, antidepressant, anti-allergic, anti-inflammatory, antisecretory or anti-ulcerous effects.
摘要:
Methods for improving solubility and bioavailability of lipophilic compounds are described. Particularly, described are stabilized supersaturated solid solutions, particularly in power from, of lipophilic drugs, such as steroidal molecules.
摘要:
The invention relates to the use of an oxidation inhibitor, i.e. active carbon, for ambient air in industrial manufacturing, especially in the processing of prostane derivatives, whereby the oxidation inhibitor removes ozone from the process air before contact with said prostane derivatives. The concentration of decomposition products is reduced.
摘要:
A transdermal therapeutic system is described, which is characterized in that it contains a crystallization inhibitor and optionally penetration enhancer in an active ingredient-containing adhesive matrix.
摘要:
Pharmaceutical compositions comprise at least one active agent and a pharmaceutically acceptable carrier for application to the respiratory tract. The active agents are from the area of antivirals. The pharmaceutical compositions can be used for application to the respiratory tract in order to treat virus infections including COVID-19.
摘要:
Pharmaceutical compositions comprising low doses of sensitive complexes between an estrogen and a cyclodextrin are provided with improved stability. In specific embodiments the composition comprises a complex between ethinyl estradiol and β-cyclodextrin in a granulate preparation and in yet another embodiment the composition comprises a limited amount of polyvinylpyrrolidone since this excipient was found to degrade ethinyl estradiol. Furthermore, a method for improving the stability of an estrogen in a composition and for manufacturing such a stable composition is provided. Essentially, the granulate preparation are manufactured under careful control of the relative humidity.
摘要:
An agent for transdermal administration is described, which is characterized in that it contains gestodene esters with 1 to 20 carbon atoms in the ester radical optionally in combination with one or two estrogen(s).
