Definitions
- the present invention relates to the field of pharmaceutical products, particularly it relates to a prolonged-release pharmaceutical form based on hydralazine, which is useful as a reactivator of suppressor genes that are methylated and not expressed during the development of malignant diseases. Like cancer For this reason, they can be used to support cancer therapies.
- Hydralazine has demonstrated experimentally the excessive effect on various suppressor genes, ruling out that it is specific for a gene. This effect is confirmed in vitro and in vivo in its excessive and reactivating capacity of suppressor genes.
- the tablets are solid pharmaceutical forms that contain one or more active ingredients generally accompanied by appropriate excipients and are administered by different routes. They are prepared by applying high pressures on powders or granules, using mechanical equipment provided with appropriate dies and punches. In the formulation of tablets they are generally used as diluent excipients, binders, disintegrants and lubricants. Dyes and flavorings may also be present. Three general manufacturing methods are used: wet granulation, dry granulation and direct compression.
- the tablets can be coated to protect their components from the effects of air, moisture or light, mask unpleasant tastes or odors, improve the appearance and control the site of release of the active substance in the gastrointestinal tract. Tablets with simple covers - In some cases, the tablets are coated with sugar (dragees) which is applied by means of aqueous suspensions. The coated tablets are then polished by the application of dilute wax solutions in solvents such as chloroform or powder mixtures. The coatings that Consist of substances such as shellac or cellulose acetophthalate are often applied with non-aqueous solvents before the application of the sugary coating.
- enteric coatings When the active substance can be destroyed or inactivated by gastric juice or when it can irritate the gastric mucosa, the use of enteric coatings is indicated. These coatings are intended to retard. release of the active substance until the tablet has passed through the stomach.
- delayed release In the Pharmacopoeia of the United Mexican States, Seventh Edition, the term delayed release is used and the corresponding monographs include tests and specifications for the release of the active substance.
- Prolonged-release tablets - They are formulated in such a way that the release of the active substance occurs for a prolonged period of time after administration. Expressions such as extended release, prolonged action, repeated action and sustained release are also used to describe such pharmaceutical forms. However, the term prolonged release is used for pharmacopoeial purposes and requirements for release.
- Forms of delayed release The active substance is released 'globally, but not immediately after administration, but after a certain time (2-4 hours).
- the objective is to avoid the action of gastric secretions, so that the medicine comes into contact with organic fluids only when the orally administered form has reached the intestinal tract.
- Forms of prolonged release are those in which after an initial release of a certain proportion of the active substance, the release of this continues for a certain time (at least 6-8 hours), in such a way that ensures therapeutic plasma levels during this period. With this type of release system even without modifying the dose, or with a slightly more spaced interval (for example every 8-12 hours), non-fluctuating therapeutic levels are achieved, constantly within the therapeutic range.
- the maximum sustained release time of the drug is limited by the time that transit of that form can last through the patient's intestinal tract (24-48 hours).
- both systems tend to be considered more as forms of continuous release, reserving the term sustained release for other pharmaceutical forms (especially injectable deposits or subcutaneous implants) that allow, with a single application of the drug, a sustained therapeutic action during periods of very long time (months and even years).
- 4,606,909 refers to pharmaceutical formulations based on homogeneous pellets that are finally coated with a polymer that controls the release rate.
- a polymer that controls the release rate it can be seen that it is a chemical form of delayed release, since the appearance of the peak of maximum concentration is delayed. For this it is necessary to consider that the whole drug is released when the total erosion of the coating is reached in the intestine, at approximately a pH of 6.5.
- the formulations developed by the methods of this patent are only suitable for filling in capsules, since it is essential that the pellets are kept free and independent of each other. This type of formulation tends to be useful as a delayed release method but not controlled release.
- one of the objects of the present invention is to provide a pharmaceutical formulation based on tablets formed by a polymer matrix, active and excipients.
- Another object of the present invention is to provide a prolonged release system of a drug that releases the active ingredient at the rate necessary to reach and maintain a constant concentration of said active ingredient in the blood.
- Still another of the objectives of the present invention is to provide a system of prolonged release of an active ingredient such as hydralazine, whose release is equivalent to a concentration analogous to a continuous intravenous infusion where hydralazine is administered to the patient at a constant rate and equal to the rate of elimination.
- an active ingredient such as hydralazine
- Another of the additional objects of the present invention is to provide an extended release system based on hydralazine, whose release rate is independent of the amount of hydralazine that remains within the dosage form, said rate being also constant release over A certain period.
- a further object of the present invention is to provide an extended release system based on a pharmaceutical composition of hydralazine such that it has a therapeutic level rapidly and at a sustained and uniform concentration for a given period of time
- the dosage form generally consists of two parts: an initial dose that releases the drug immediately and a maintenance dose responsible for prolonged release appropriate for the treatment of cancer.
- the graph of Figure 1 shows the typical release profile (amount of drug released [Q] against time) obtained from one of the compositions that are covered by the present invention.
- the graph in Figure 2 shows a mathematical transformation of the typical release profile shown in Figure 1.
- the graph of Figure 3 shows another of the typical release profiles (amount of drug released [Q] against time) obtained from one of the compositions according to the present invention.
- the graph in Figure 4 shows a mathematical transformation of the typical release profile shown in Figure 3.
- the present invention relates to a prolonged release pharmaceutical composition based on hydralazine.
- the dosage form generally consists of two parts: an initial dose that releases hydralazine immediately and a maintenance dose responsible for the Prolonged release of hydralazine in proportions that allow it to be useful for cancer treatment.
- the present invention is based on the recognition of the pharmacokinetic parameters of hydralazine reported in the literature. Based on the results of the Owners and collaborators (Reactivation of tumor suppressor genes by the cardiovascular drugs hydralazine and procainamide and their potential use in cancer therapy; in Clinical Research VoI. 9, 1596 - 1603, May 2003) close release rates are conveniently required at 7.58 mg / hr for 24 hours to be able to be used in the reported treatments maintaining the desired demethylating effect and avoiding the hypotensive effect.
- the pharmaceutical composition object of the present invention is formed as follows: 10 to 70% hydralazine hydrochloride as active ingredient; 3 to 50% of a polymer limiting the rate of release based on some of the following compounds or a combination of them: ethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methylcellulose, hydroxyethyl cellulose, derivatives of methacrylic acid or carbomer, among others; 15 to 40% of a diluting agent based on starch, lactose, microcrystalline cellulose, monobasic or dicalcium calcium phosphate, carbohydrate-derived alcohols such as sorbitol or mannitol or mixtures of all of the above; 5 to 20% of a hydrophilic polymer moderating the release rate based on starch and its derivatives, alkylated cellulose derivatives such as methylcellulose, carboxymethyl cellulose, carbomer, natural gums such as acacia or xanthan gum, polyvinylpyrrolidone, car
- a prolonged release composition of hydralazine was prepared in the following proportions:
- Hydroxypropyl methylcellulose 2208 USP from 42 to 44%
- Microcrystalline cellulose PH 200 25 to 28%
- a prolonged release composition of hydralazine was prepared in the following proportions:
- the graph of Figure 4 also shows a mathematical transformation of the typical release profile of the composition prepared according to the present invention referred to in Figure 3, according to the Matrix Release Theory of T. Higuchi, which predicts a linear relationship between the amount of drug released, Q, and the square root of time, t, observing in this specific case that this linear relationship is preserved until almost 22 hours.
