Definitions

  • the present invention relates to anti-inflammatory and/or analgesic formulations for the treatment of humans or animals.
  • the formulations can also be used in the treatment of neurodegenerative disease.
  • the combination of active ingredients 4-hydroxy-3-methoxyacetophenone (apocynin) and 2- hydroxy-4-methoxyacetophenone (paeonol) to form a medication for use as an anti- inflammatory is known.
  • One such preparation is known as APPA and has had positive results in the treatment of osteoarthritis in dogs.
  • the APPA formulation combines the active ingredients with a solid excipient.
  • solid dose forms such as tablets, heat induced on the tablet during the granulation process and/or on tablet compression can cause transient melting of the low melting point paeonol and subsequent adverse transformation of the physical properties of the active ingredient.
  • Solid phase pharmaceutical preparations also exhibit inferior bioavailability to liquid preparations.
  • the active ingredients can be brought into the liquid phase by dissolution or suspension in an appropriate liquid and then encapsulated, or in the form of a standardised liquid extract which must be orally ingested by the patient.
  • Such liquid phase preparations possess a reduced concentration of active ingredients. This results in an increase in the number of capsules that need to be taken or increased amount of liquid extract that must be drunk. This is not desirable because the formulation does not taste pleasant and patients prefer not to take large numbers of capsules or drink a large amount of unpleasant tasting medicine.
  • Paeonol is 2-hydroxy-4-methoxyacetophenone and is shown by the following formula:
  • Apocynin is a plant phenol 4-hydroxy-3-methoxyacetophenone, and has the following formula:
  • Paeonol is a solid with a low melting point of around 49.7 ° C according to our studies.
  • Apocynin is a solid with a much higher melting point of around 1 14.6 ° C according to our studies.
  • APPA is a mixture of paeonol and apocynin, as indicated above.
  • the compounds are known to be effective in the treatment of inflammatory diseases when mixed at a ratio (by weight) of around 3.5 paeonol : 1 apocynin.
  • the applicants have surprisingly found that at (or close to) this ratio a eutectic mixture is formed resulting in a significantly lowered combined melting point of 44.7 ° C; below that of both paeonol and apocynin. This is the lowest possible melting point for an APPA system over all mixing ratios.
  • the applicants have further found that addition of a relatively small quantity of an excipient to the eutectic APPA mixture provides a liquid form of APPA which is stable at room temperature.
  • the excipient may be any suitable oxygenated compound of low toxicity.
  • a number of excipient materials may be suitable including glycols and glycol derivatives, polyhydric alcohols, esters and ethers.
  • the resulting liquid formulation possesses a relatively high concentration of active compounds.
  • the stable liquid formed contains 64.3 % APPA by weight. Due to the liquid having a high density of 1.1659 g/ml, this equates to 74.5 % APPA on a weight per volume basis. Accordingly, the liquid formulation of the invention may provide a highly concentrated form of APPA. The production of such a highly concentrated liquid formulation made from a eutectic mixture of APPA can be seen as a remarkable discovery allowing for a significant improvement in patient dosing and compliance (amongst other things).
  • Isomers of apocynin and paeonol are known in the art. Isomers of apocynin and paeonol include 2-hydroxy-3-methoxyacetophenone “orthoacetovanillone” (CAS: 703-98-0), 2- hydroxy-5-methoxyacetophenone (CAS: 705-15-7), 3-hydroxy-4-methoxyacetophenone “isoacetovanillone” (CAS: 6100-74-9) and 4-hydroxy-2-methoxyacetophenone“isopaeonol” (CAS: 493-33-4).
  • a liquid formulation comprising active compounds 2-hydroxy-4-methoxyacetophenone (paeonol) or isomer thereof and 4-hydroxy- 3-methoxyacetophenone (apocynin) or isomer thereof wherein the ratio by weight of paeonol to apocynin is from 3:2 to 9:1.

  • the ratio by weight of total active compounds to excipient is from 2:3 to 9:1.
  • Apocynin and paeonol are isomers of each other. It will be appreciated that according to the present invention the liquid formulation comprises two different active compounds (e.g. apocynin itself and paeonol itself).
  • the excipient may be any suitable oxygenated compound of low toxicity. It will be appreciated that in the context of the present invention the term low toxicity may refer to a material whose toxicity is suitable for long term oral administration along with APPA to humans without adverse effects.
  • the excipient is a glycol or glycol derivative, a polyhydric alcohol, or an ester and/or ether thereof.
  • the excipient is a glycol.
  • the excipient is a polyethylene glycol. More preferably the excipient is polyethylene glycol 400.
  • a preferred formulation has a ratio by weight of paeonol or isomer thereof to apocynin or isomer thereof that is from 80:20 to 77.7:22.3.
  • the ratio by weight of total active compounds to excipient is 64:36.
  • the formulation is a stable liquid at room temperature (15 to 25 ° C).
  • a high concentration of APPA formulation allows for an acceptable dose to be contain within a single soft gel capsule.
  • a 0.533 ml mixture of 3.5 paeonol : 1 apocynin with 2.5 parts PEG 400 contains 400 mg of APPA.
  • a 1.07 ml mixture of 3.5 paeonol : 1 apocynin with 2.5 parts PEG 400 contains 800 mg of APPA.
  • liquid formulation made from a eutectic mixture comprising active compounds paeonol or isomer thereof and apocynin or isomer thereof.

If natural apocynin is used the skilled person would readily understand how to adjust the ratios to produce a formulation of the invention. However, if this is the case it may be necessary to limit the amount of picrorrhiza kurroa to prevent side effects (such as stomach upset which may occur due to other phytochemical species in the picrorrhiza kurroa). However, it is noted that most human subjects can take up to 2,000 mg of picrorrhiza kurroa (Kutkin min 2%) per day without discomfort.
