Methods of treating a patient afflicted with non-alcoholic steatohepatitis (NASH)
Pharmaceutical carriers which provide an environment of physical and chemical stability comprising a therapeutically effective amount of an active pharmaceutical ingredient (API) compound of structure I, one or more antioxidants, one or more chelators and a vehicle base comprising water and one or more pharmaceutically acceptable non-aqueous solvents, one or more absorption enhancers, one or more gelling agents and one or more pH buffering agents are described.
1. A method of treating a patient afflicted with Non-alcoholic Steatohepatitis (NASH) which comprises applying to a patient's skin a pharmaceutical composition effective to treat the patient and alleviate the patient's NASH, wherein the pharmaceutical composition comprises a pharmaceutically acceptable carrier and a compound which has the structure:
or a pharmaceutically acceptable salt or ester of the compound in an amount effective to treat the patient, and
wherein the pharmaceutically acceptable carrier (A) provides an environment of physical and chemical stability, (B) enables retention of the amount of the compound effective to treat the patient in the patient's skin, (C) permits only a low level of the compound to enter and accumulate in the patient's systemic circulation, and (D) comprises:
(i) ethanol at a concentration of 10.00% w/w;
(ii) phenoxyethanol at a concentration in the range 0.1-5.0% w/w;
(iii) diethylene glycol mono-ethyl ether (otherwise known as DEGEE or Transcutol P®) at a concentration in the range 5.0-40.0% w/w;
(iv) propylene glycol at a concentration in the range 5.0-40.0% w/w;
(v) PEG400 at a concentration in the range 5.0-40.0% w/w;
(vi) carbomer homopolymer type C980 at a concentration in the range of 0.5 to 2.0% w/w;
(vii) butylated hydroxytoluene (BHT) at a concentration of at least 0.05% w/w;
(viii) di-sodium EDTA at a concentration of at least 0.001% w/w;
(ix) trolamine at a concentration sufficient to provide an apparent pH in the range 6.50 to 7.50; and
(x) water at a concentration of 19.02-22% w/w.
2. The method of claim 1 wherein the pharmaceutically acceptable carrier comprises:
(i) ethanol at a concentration of 10.0% w/w;
(ii) phenoxyethanol at a concentration of 1% w/w;
(iii) diethylene glycol mono-ethyl ether (otherwise known as DEGEE or Transcutol P®) at a concentration of 25.0% w/w;
(iv) propylene glycol at a concentration of 20.0% w/w;
(v) PEG400 at a concentration of 21.0% w/w;
(vi) carbomer homopolymer type C980 at a concentration of 1.0% w/w; and
(vii) water at a concentration of 19.5-22% w/w.
3. The method of claim 2 , wherein the pharmaceutically acceptable carrier comprises:
(i) ethanol at a concentration of 10.0% w/w;
(ii) phenoxyethanol at a concentration of 1% w/w;
(iii) diethylene glycol mono-ethyl ether (otherwise known as DEGEE or Transcutol P®) at a concentration of 25.0% w/w;
(iv) propylene glycol at a concentration of 20.0% w/w;
(v) PEG400 at a concentration of 21.0% w/w;
(vi) carbomer homopolymer type C980 at a concentration of 1.0% w/w;
(vii) butylated hydroxytoluene (BHT) at a concentration of 0.1% w/w;
(viii) di-sodium EDTA at a concentration of 0.005% w/w;
(ix) trolamine at a concentration of 0.375% w/w; and
(x) water at a concentration of 19.02-21.52% w/w.
4. The method of claim 1 , wherein the amount of the compound present in the pharmaceutical composition is a concentration of the compound up to 2.50% w/w.
5. The method of claim 4 , wherein the amount of the compound present in the pharmaceutical composition is a concentration of the compound of 0.25%, 0.75% or 1.75% w/w.
6. The method of claim 5 , wherein the amount of the compound present in the pharmaceutical composition is a concentration of the compound of 1.75% w/w.
7. The method of claim 3 , wherein the amount of the compound present in the pharmaceutical composition is a concentration of the compound up to 2.50% w/w.
8. The method of claim 7 , wherein the amount of the compound present in the pharmaceutical composition is a concentration of the compound of 0.25%, 0.75% or 1.75% w/w.
9. The method of claim 8 , wherein the amount of the compound present in the pharmaceutical composition is a concentration of the compound of 1.75% w/w.
