Imipramine Warfarin

Among the most frequently used organic solvents is chloroform, used for the determination of many analytes in various samples free cyanide and thiocyanate ions in human saliva chlorophenols in urine and Bi(III), ethambutol hydrochloride, diclofenac, phenothiazine derivatives, imipramine, warfarin, flufenamic acid, and ethylmorphine in pharmaceutical preparations. Another proposed solvent is dichloro-ethane, used for the determination of bromhexine in serum and imipramine, ambroxol, berberine, bromhexine, neostigmine, 8-chlorotheophylline, and diphenhydramine in pharmaceutical samples.

Clinicians should be aware of a few drug interactions with Zolpidem. Flumazenil acts as an antagonist to the hypnotic effects of zolpidem. There is decreased alertness when zolpidem is combined with cimetidine. There is an increase in anterograde amnesia in volunteers treated with a combination of imipramine and zolpidem. Haloperidol, ranitidine, chlorpromazine, warfarin, and digoxin, along with cimetidine and flumazenil, do not alter the pharmacokinetics of zolpidem (Salva and Costa, 1995).
