They showed that small doses of 2.5–7.5<span class="elsevierStyleHsp" style=""></span>mg of MTX given at intervals of 12<span class="elsevierStyleHsp" style=""></span>h for a total of three doses every week had an improvement from 75% to 100% in 26 patients with severe Psoriasis, with minimal adverse effects (nausea, oral ulcers and hives).</p><p id="par0030" class="elsevierStylePara elsevierViewall">Chladek et al.<a class="elsevierStyleCrossRef" href="#bib0075"><span class="elsevierStyleSup">5</span></a> conducted a study that related the pharmacodynamics and pharmacokinetics of divided doses (2.5<span class="elsevierStyleHsp" style=""></span>mg and 5<span class="elsevierStyleHsp" style=""></span>mg three times a week) and weekly full doses (7.5<span class="elsevierStyleHsp" style=""></span>mg and 15<span class="elsevierStyleHsp" style=""></span>mg) of MTX with the Psoriasis Area Severity Index of 41 patients with severe disease. They concluded that split doses of MTX were associated with greater efficacy and lower risk of acute adverse effects during anti-psoriatic therapy.</p><p id="par0035" class="elsevierStylePara elsevierViewall">In the rheumatology field, Dhaon et al.<a class="elsevierStyleCrossRef" href="#bib0080"><span class="elsevierStyleSup">6</span></a> randomly divided 135 patients with rheumatoid arthritis into three groups: group 1 on split 7.5<span class="elsevierStyleHsp" style=""></span>mg doses of oral MTX two or three times weekly; group 2 on single 15–22.5<span class="elsevierStyleHsp" style=""></span>mg of oral MTX weekly; and group 3 on single intramuscular 15–22.5<span class="elsevierStyleHsp" style=""></span>mg dose of MTX weekly. Clinical efficacy of split and intramuscular doses was superior to single oral dose, but intramuscular administration lead to greater discomfort on patients. In addition, split doses group showed the lowest rates of gastrointestinal side effects, with higher levels of alopecia.</p><p id="par0040" class="elsevierStylePara elsevierViewall">Pharmacokinetic studies demonstrate enhanced bioavailability of the drug with multiple dosing, supporting the clinical superiority of divided doses compared to single oral dose. Hoekstra et al.,<a class="elsevierStyleCrossRef" href="#bib0100"><span class="elsevierStyleSup">10</span></a> compared blood samples of 10 rheumatoid arthritis patients with fluorescence polarization immunoassay technique who received a single oral dose of 25–35<span class="elsevierStyleHsp" style=""></span>mg MTX, and after one week, divided two or three doses every 8<span class="elsevierStyleHsp" style=""></span>h. Bioavailability of split doses was 28% significantly higher than single doses and similar to that of subcutaneous doses, obtained from a previous study. The authors concluded that when high-dose of MTX is needed, the divided dose is an effective and comparable alternative to subcutaneous administration.</p><p id="par0045" class="elsevierStylePara elsevierViewall">After demonstrating and bringing up the efficacy and safety of MTX split oral doses in patients with Psoriasis, it is important to remember that there are limitations and drawbacks in their use, mainly with delivery errors. Because patients must take three weekly doses of 2.5<span class="elsevierStyleHsp" style=""></span>mg or 5<span class="elsevierStyleHsp" style=""></span>mg, and MTX tablets are mainly available at 2.5<span class="elsevierStyleHsp" style=""></span>mg and 10<span class="elsevierStyleHsp" style=""></span>mg in this region, patients may accidentally fail in both: reduncing or increasing the dose. However, in our experience this accident is very uncommon.</p><p id="par0050" class="elsevierStylePara elsevierViewall">In conclusion, MTX remains as a first-line treatment for severe Psoriasis, and accessible in many Latin American countries. Enteral and parenteral weekly divided doses of MTX show similar efficacy and safety in several studies both in psoriatic and rheumatologic patients. Therefore, we should continue proposing low split oral doses in future guidelines and consensus, in comparison to the single oral dose, with the benefit of achieving greater adherence by reducing adverse effects, taking into account their limitations.</p><span id="sec0005" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0005">Conflict of interest</span><p id="par0055" class="elsevierStylePara elsevierViewall">The authors declare no conflict of interest.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:2 [ 0 => array:2 [ "identificador" => "sec0005" "titulo" => "Conflict of interest" ] 1 => array:1 [ "titulo" => "References" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "bibliografia" => array:2 [ "titulo" => "References" "seccion" => array:1 [ 0 => array:2 [ "identificador" => "bibs0005" "bibliografiaReferencia" => array:10 [ 0 => array:3 [ "identificador" => "bib0055" "etiqueta" => "1" "referencia" => array:1 [ 0 => array:2 [ "contribucion" => array:1 [ 0 => array:2 [ "titulo" => "Global epidemiology of psoriasis: a systematic review of incidence and prevalence" "autores" => array:1 [ 0 => array:2 [ "etal" => false "autores" => array:5 [ 0 => "R.
