There are examples of common drugs, like ibuprofen, where the use of chiral switching has caused controversy. Ibuprofen is a racemic mixture where the S-enantiomer is known to play a major role in reducing inflammation as it inhibits COX-2 (cooxygenase 2) compared to the R-enantiomer; the fact that the S-enantiomer is stronger is what led to ...
An enantiomeric pair (S,S)- and (R,R)-ethambutol, along with the achiral stereoisomer called meso-form, it holds a diastereomeric relationship with the optically active stereoisomers. The activity of the drug resides in the (S,S)-enantiomer which is 500 and 12 fold more potent than the (R,R)-ethambutol and the meso-form. The drug had initially ...
(S,S)-(+)-Ethambutol is powerful and selective antitubercular drug.It is a typical example of an old drug that was introduced for clinical use in its unichiral form. . Ethambutol contains two constitutionally symmetrical chiral centers in its structure and exists in three stereoisomeric forms, the enantiomeric pair (+)-(S,S)- and (−)-(R,R)-ethambutol, along with the achiral stereoisomer called m
amitriptyline – tricyclic antidepressant used to treat separation anxiety, excessive grooming dogs and cats; amlodipine – calcium channel blocker used to decrease blood pressure; amoxicillin – antibacterial; apomorphine – emetic (used to induce vomiting) artificial tears – lubricant eye drops used as a tear supplement
Most dogs, however, will need radiation, chemotherapy, and other medications. Even with those therapies, the survival time is short, so ivermectin could help if it proves to be useful.

Management of tuberculosis refers to techniques and procedures utilized for treating tuberculosis (TB), or simply a treatment plan for TB.. The medical standard for active TB is a short course treatment involving a combination of isoniazid, rifampicin (also known as Rifampin), pyrazinamide, and ethambutol for the first two months.
