Clinical Study of 320 Patients

In a longitudinal study of 320 patients, we assessed today's acute inpatient treatment of depressive (ICD10 F3) and schizophrenic (ICD10 F2) disorders with focus on therapeutic strategies, medications, adverse side effects, time course of recovery, and efficacy of treatments. Of particular interest was the weighing of the benefits and drawbacks of polypharmacy regimens. Polypharmacy was by far the most common treatment regimen (85%). On average, patients received 4.50 ± 2.68 medications, consisting of 3.30 ± 1.84 psychotropic drugs, plus 0.79 ± 1.13 medications that alleviate adverse side effects, plus 0.41 ± 0.89 other somatic medications. The treating psychiatrists appeared to be the main determining factor in this context, while «previous history» and «severity at baseline» played a minor role, if at all.

Adverse Drug Reactions

Adverse drug reactions were found to be an inherent component of polypharmacy and tended to have a 2-3 times higher incidence compared to monotherapy. Severe adverse reactions could not be attributed to a particular drug or drug combination. Rather, the empirical data suggested that severe side effects can be triggered by virtually all combinations of drugs, provided patients have a respective vulnerability. In terms of efficacy, there were no advantages of polypharmacy over monotherapy.

Recommendations

Polypharmacy regimens are not equally suited for every patient. Specifically, such regimens appear to have a negative impact on treatment outcome and to obfuscate the «natural» time course of recovery through a multitude of interfering factors. Evidence clearly speaks against starting just every therapeutic intervention in psychiatry with a combination of psychopharmaceuticals. We think that it is time for psychiatry to reconsider its treatment strategies, which are far too one-sidedly fixated on psychopharmacology and pay far too little attention to alternative approaches, especially in mild cases where psychotherapy without concurrent medication should still be an option. Also, regular exercises and sports can definitely be an effective therapeutic means in a considerable number of cases. General practitioners (GPs) are particularly in demand here [Stassen et al. 2021].

vSpacer Adverse side effects under polypharmacy
Most patients experience significant adverse side effects induced by their psychotropic medications. As many as 87.3% of the F2 patients reported at least «some» mild adverse effects, of which 39.4% were of severe or very severe form. The differences to F3 patients are marginal.
