The improved solid pharmaceutical composition of the present invention is characterized by physicochemical properties suitable for the tabletformulation by wet granulation, the adequate release rate of the active ingredient (an antiviral agent such as Valaciclovir or a pharmaceuticalacceptable salt or derivative thereof) and the storage stability, by employing suitable pharmaceutically acceptable excipients. The pharmacotechnicalproperties of pharmaceutical tablets include friability, hardness and flowability of the granules. Some of the problems that are encountered whenproducing tablets comprising high dose active ingredients are friction and shock that most often cause tablets to chip or break. Generally, themechanical strength of a tablet formulation provides a measure of the bonding potential of the tablet contents and this information depends upon theselection of suitable excipients..

A preferred form of Valacyclovir is the Valaciclovir hydrochloride salt. After oral administration, Valaciclovir hydrochloride is rapidly absorbedfrom the gastrointestinal tract and nearly completely converted to acyclovir and L -valine by first-pass intestinal and/or hepatic metabolism byenzymatic hydrolysis. It has been shown that Valaciclovir provides a high bioavailability of acyclovir, 3- to 5- fold higher than that obtained withoral acyclovir, and it is equivalent to plasma levels achieved with doses of intravenous acyclovir..
The produced tablets were tested for content uniformity, disintegration, water content and dissolution proving that they are meeting thespecifications.. Aciclovir fidia compresse acquistare on-line .

Finally, it was formulated in a solid dosage form by compressing it into a desired tablet form. Subsequently, the tablets were film-coated.Tabletsprepared according to example 1 demonstrate good hardness (>80 Nt), very good friability (0.17%) and the granule has excellent flowability (Carr'sindex 11.8%)..
Il trattamento va continuato per 5 giorni, ma può rendersi necessario un prolungamento nei casi di infezioni primarie gravi.. Aciclovir fidia compresse.
Furthermore, the disintegration performance of the Valaciclovir tablet is also quite long and therefore any possible solution to the hardness andfriability problem should not have a substantial deleterious effect on either the disintegration time or lubrication of the tablet. The formulation ofValaciclovir granules was also found to be problematic due to the adhesive properties of Valaciclovir and also to problems relating to the pHdependent dissolution rate and discolouration of the granules. Granules of Valaciclovir itself tend to be fragile and have a low coating efficacy.Furthermore, there is a need to mask the bitter taste of Valaciclovir..

An excipient is considered to be "incompatible" with an active ingredient (an antiviral agent such as Valaciclovir or a pharmaceutical acceptable saltor derivative thereof) if itinhibits the dissolution rate of said active ingredient, that is to say, if said active ingredient (an antiviral agentsuch as Valaciclovir or a pharmaceutical acceptable salt or derivative thereof) dissolves less or slower in the presence of said excipient whencompared with the dissolution rate of said active ingredient on its own. The terms "incompatibility", "compatible" and "compatibility" are definedaccordingly. The active ingredient (Valaciclovir or a pharmaceutical acceptable salt or derivative thereof) contained in a dosage form is"bioavailable", if when administered in a dosage form is released from the dosage form, absorbed and reaches, at least the same, concentration levelsin plasma as any of the marketed products containing the same quantity of the same active ingredient and intended for the same use..
Acyclovir is a known compound widely used for the treatment of viral infections, particularly infections caused by the herpes virus. Pharmacokineticstudies have shown that acyclovir is poorly water soluble and presents poor oral bioavailability, therefore intravenous administration is required inorder to achieve high concentrations in the plasma.. aciclovir fidia compresse acquistare on-line .
Moreover, any excipient may optionally be added to the above composition, provided that they are compatible with the active ingredient of thecomposition, in order to overcome problems associated with the poor flow properties and unfavorable pharmacotechnical characteristics of thesesubstances, and in order to increase the stability and the dissolution rate of the finished dosage form, and provide a product exhibiting excellentbioavailability..
