Abstract

L-carnitine, acetyl L-carnitine and propionyl L-carnitine inner salts, or their pharmaceutically acceptable salts, are used in combination to treat oligoasthenoteratosperia including oligospermia, asthenospermia, and teratospermia.

10. The method according to claim 9 , in which the unit dosage form contains 2 g of L-carnitine inner salt, 1 g acetyl L-carnitine inner salt and 0.5 g of propionyl L-carnitine inner salt or equimolar amounts of their pharmaceutically acceptable salts.

11. A method for the treatment of oligoasthenoteratospermia consisting of administering to a patient in need thereof an effective amount of a combination of L-carnitine, acetyl L-carnitine and propionyl L-carnitine inner salts, or of their pharmaceutically acceptable salts and suitable excipients, wherein the pharmaceutically acceptable salt is not zinc citrate.

12. The method according to claim 11 in which the pharmaceutically acceptable salt is selected from the group consisting of chloride, bromide, orotate, aspartate, acid aspartate, citrate, acid citrate, magnesium citrate, phosphate, acid phosphate, fumarate, acid fumarate, magnesium fumarate, glycerophosphate, lactate, maleate and acid maleate, mucate, oxalate, acid oxalate, pamoate, acid pamoate, sulphate, acid sulphate, glucose phosphate, tartrate, acid tartrate, magnesium tartrate, 2-amino ethane sulphonate, magnesium 2-amino ethane sulphonate, methane sulphonate, choline tartrate, trichloroacetate and trifluoroacetate.

13. The method according to claim 11 , wherein oligospermia is treated.

14. The method according to claim 11 , wherein asthenospermia is treated.

15. The method according to claim 11 , wherein teratospermia is treated.

16. The method according to claim 11 , in which a molar ratio of L-carnitine to acetyl L-carnitine and propionyl L-carnitine or of their pharmaceutically acceptable salts ranges from 2.48:0.098:0.092 to 0.186:0.98:0.92.

17. The method according to claim 11 , in which a molar ratio of L-carnitine to acetyl L-carnitine and propionyl L-carnitine or of their pharmaceutically acceptable salts ranges from 2.48:0.49:0.46 to 0.62:0.49:0.46.

18. The method according to claim 11 , in which a molar ratio of L-carnitine to acetyl L-carnitine and propionyl L-carnitine or of their pharmaceutically acceptable salts ranges from 2.48:0.98:0.92 to 1.24:0.49:0.23.
