RIFAPENTINE HYDROHALOGENS. |
| abstract |
The addition salt of rifapentin with hydrochloric and hydrobromic acid is obtained from the bases in the free state as well as aqueous solutions of hydrohalic acid. Crystallization from different organic solvents or precipitation from solvents by addition of non-solvents produces two distinct polymorphs as well as the amorphous form. The polymorphs exhibit high stability in storage and also under the conditions usually employed for the preparation of pharmaceutical dosage forms. |
