Pgp inhibition by drugs may play an important role in drug safety, by increasing plasma and brain concentrations of coadministered drugs and thus causing adverse drug reactions. No evidence for a potent drug-drug interaction was found with fluoxetine 35, 37 ; . Based on these in vitro data 36 ; , sertraline and paroxetine exhibited the greatest potential for affecting the pharmacokinetics of coadministered drugs at the level of Pgp. However, at usual therapeutic doses of paroxetine and sertraline, the IC 50 value for the inhibition of Pgp is around 250-fold higher than the plasma concentration for paroxetine and around 500-fold higher for sertraline 38 ; , suggesting that even if the accumulation of sertraline within the cell e.g., in the biliary or renal system ; is taken into account, the Pgp inhibition observed in vitro might not be clinically relevant. This is substantiated by the fact that neither sertraline 39 ; nor fluvoxamine 40 ; nor citalopram 41 ; had a clinically relevant influence on the pharmacokinetic parameters of digoxin, a Pgp prototype substrate. On the other hand, in addition to being an inhibitor of CYP2D6, paroxetine is a substrate for this isozyme, whose activity is regulated by a genetic polymorphism. In the absence of active enzyme poor metabolizer ; plasma paroxetine concentrations are up to 25-fold higher than in extensive metabolizers 42 ; . Therefore, one cannot exclude that in poor metabolizer patients that the administration of high paroxetine doses may translate into clinically relevant changes in the pharmacokinetics of concomitantly administered Pgp substrates. It remains to be studied whether the inhibition of Pgp by the newer antidepressants might lead to drug-drug interactions in patients. Such interactions might, for instance, be relevant when drugs with low oral bioavailability due to substantial transport back into the gut lumen are to be coadministered, as has be shown for loperamide when given in combination with quinidine 43 ; . Specific Drugs. Selective Norepinephrine Reuptak e Inhibitors SNRIs ; Despite the current popularity of the SSRIs for the treatment of depression, the noradrenergic neurons should not be overlooked because they also influence the depressed mood 44 ; . The noradrenergic system appears to be associated with increased drive, whereas the serotonergic system relates more to changes in mood Fig. 45.1 ; . Thus, the different symptoms of depression may benefit from drugs acting mainly on one or other of the neurotransmitter systems 18 ; . The SNRIs Fig. 45.7 ; seem to be at least as effective as the SSRIs in the treatment of depressive illness 44 ; by acting specifically at noradren ergic sites. Thus, the SSRIs and SNRIs influence depression by parallel, independent pathways. SNRIs have a role in the treatment of depression, either alone or as adjunctive therapy. The SNRI antidepressants are well tolerated but possess different adverse event profiles. The selectivity ratios Fig.45.5 ; show that the SNRIs, as a group, are potent selective inhibitors of the NE reuptake transporter, and that the secondary amine TCAs are substantially more potent with regard to their inhibition of NE reuptake in comparison to the SSRIs. Their in vitro affinity for inhibiting the NE transporter essentially mirrors more or less their clinical efficacy as SNRIs 12 ; : desipramine protriptyline amitripptyline nortriptyline reboxetine maprotiline amoxapine imipramine paroxetine. The level of affinity of the SNRIs for NET is not predictive for antidepressant activity and azmacort.

It is very important with amirtiptyline to begin with a tiny dose 10 mg ; , as many patients cannot tolerate more than 5 or 10 mg. Step Therapy: In some cases, we require you to first try one drug to treat your medical condition before we will cover another drug for that condition. For example, if Drug A and Drug B both treat your medical condition, we may require your doctor to prescribe Drug A first. If Drug A does not work for you, then we will cover Drug B. Generic Substitution: When there is a generic version of a brand-name drug available, our network pharmacies will automatically give you the generic version, unless your doctor has told us that you must take the brand-name drug. If your physician determines that you are not able to meet a prior authorization, quantity limit, step therapy restriction, generic substitution, or other utilization management requirement for medical necessity reasons, you or your physician may request an exception. See Section 6 to learn more about how to request an exception.
