Definitions
- transdermal administration has enabled many drugs to be effectively administered via the transdermal route. These advances include the development of many physical methods to increase skin permeability and facilitate transdermal administration, such as the use of iontophoresis, electroporation, ultrasound or microneedles. However, drugs that can be effectively and safely administered through the skin for 7 days or more without causing skin adhesion, skin irritation or sensitization are still limited.
- Risperidone is a highly effective drug with a relatively narrow therapeutic index. It may produce adverse side effects in overdose, most notably extrapyramidal syndrome (EPS) and, to a lesser extent, hypotension (due to peripheral ⁇ -adrenergic activity).
- EPS extrapyramidal syndrome
- hypotension due to peripheral ⁇ -adrenergic activity.
- the total daily dose of risperidone ranges from about 2 to about 8 mg; in order to alleviate behavioral disorders associated with neurodegenerative diseases, the total daily dose is usually less, usually in the range of about 0.5 to about 2 mg.
- patients need to be dose-titrated in order to obtain an effective dose.
- Risperidone is metabolized to 9-hydroxyrisperidone, which has pharmacological properties and potency comparable to the parent drug risperidone, but with a longer elimination half-life. Risperidone is distributed to and eliminated from brain tissue more rapidly than its metabolite, 9-hydroxyrisperidone.
- Isoquinoline-type genetic polymorphisms play a unique role in the metabolism of risperidone. Humans can be classified as poor metabolizers, intermediate metabolizers, or extensive metabolizers based on the metabolic rate.
- the metabolic rate is defined as the ratio of the urinary recovery of isoquinoline to the urinary recovery of the 4-hydroxyisoquinoline metabolite of isoquinoline within 8 hours after oral ingestion of 10 mg of isoquinoline.
- Orientals more than 99% of the population can be phenotyped because extensive and poor metabolizers are quite rare. However, in Caucasians, only about 90% of the population can be phenotyped as extensive or intermediate metabolizers.
- risperidone and 9-hydroxyrisperidone are largely dependent on the isoquinoline metabolism rate of human subjects treated with risperidone. More specifically, when the total daily dose is administered as a single dose, high instantaneous peak levels of risperidone may be achieved in poor metabolizers. This may Can cause undesirable side effects, such as extrapyramidal syndrome (EPS) and hypotension (due to adrenergic effect).
- EPS extrapyramidal syndrome
- hypotension due to adrenergic effect.
- the rapid distribution of risperidone in blood plasma and brain tissue shows that the drug can be better regularly divided and administered, and preferably with a continuously controlled rate to avoid the possibility of too high peak level (and side effect), while maintaining clinically effective drug levels.
- the rate-controlled transdermal administration system will obviously provide a practical solution to the above problems.
- the transdermal administration system can deliver drugs at a substantially constant rate for at least about 24 hours, while the amount of drug in the unused and exhausted system is kept to a minimum.
- CN 101366705B and US8431152B1 describe dissolving a certain dose of risperidone in an organic solvent to prepare a corresponding patch preparation, and there is no expectation of containing risperidone dispersed in a matrix in a crystalline form.
- CN 101366705B does not disclose that the patch can be continuously applied at a constant rate for 3 days (72 hours) or longer at a therapeutically effective dose, nor does it disclose that it contains risperidone dispersed in a crystalline form in a matrix.
- Example 4 and Figure 6 of the patent show that there is no linear relationship between the cumulative release rate and the increase in the amount of risperidone.
- oleic acid is not the most preferred penetration enhancer for risperidone patches (see the last line on page 29), and laurocapram, dodecanol and propylene glycol are the preferred penetration enhancers.
- laurocapram has questionable pharmacological activity or its safety is questionable.
- Propylene glycol is a skin irritant. Propylene glycol is the solvent used to dissolve risperidone.
- transdermal administration system of risperidone or a pharmaceutically acceptable salt thereof which can continuously deliver therapeutically effective blood concentrations within 24 hours to 14 days, thereby improving patients' medication compliance and providing long-term effective treatment for schizophrenia patients.
- the present invention has now unexpectedly found that lauryl lactate and long-chain fatty alcohols are both effective skin penetration enhancers for risperidone. They have no pharmacological activity and are non-irritating to the skin.
- the present invention also unexpectedly found that microcrystalline risperidone that does not use solvent dissolution can provide long-term continuous transdermal delivery at a constant rate.
- the transdermal application system comprises risperidone crystal form A and a skin penetration enhancer (preferably lauryl lactate, a long-chain fatty alcohol such as oleyl alcohol) in combination
- a skin penetration enhancer preferably lauryl lactate, a long-chain fatty alcohol such as oleyl alcohol
- it has good stability, and can continuously deliver drugs in a controlled manner at a constant rate within a duration period of 3 days, 7 days, 10 days and 14 days, and the transdermal amount of risperidone in the 3rd-7th day after application is maintained at more than 65% of the maximum transdermal amount.
- the system continuously supplies risperidone to the skin, and the skin penetration enhancer enables the drug to penetrate the skin into the blood circulation system at a therapeutically effective dose.
- the present invention also found that by controlling the skin penetration enhancer and the risperidone crystal form A
- the dosage can increase skin flux and is beneficial to achieving the above-mentioned technical effects.
- the penetration enhancer accelerates the drug release of the transdermal administration system, which has the opposite effect to the purpose of sustained release.
- the inventors also found that a specific matrix combination can obtain a risperidone transdermal administration system with both crystalline and amorphous states, which is conducive to the continuous delivery of risperidone at a constant rate.
- an object of the present invention is to provide a matrix-type risperidone transdermal administration system, which can continuously deliver risperidone or a pharmaceutically acceptable salt thereof at a therapeutically effective blood concentration at a constant rate over 24 hours to 14 days.
