A modified-release fixed-dose formulation of orlistat and acarbose is properly tolerated and could also be an efficient approach for weight loss, in response to outcomes of a section 2a pilot research revealed in Weight problems Science and Follow.
The mix is designed to supply the weight-loss results of orlistat and to scale back orlistat’s tendency to stimulate urge for food with acarbose, in response to researchers, who cautioned that prescribing orlistat along with standard acarbose will not be really helpful.
“By altering lipid and carbohydrates digestion, the goal was to set off neuroendocrine suggestions signaling programs and thereby affect appetite,” Ulf Holmback, assistant professor within the division of public well being and caring sciences, medical vitamin and metabolism at Uppsala College, and colleagues wrote. “As well as, as glucose metabolism normally is affected in folks with weight problems and the danger of creating diabetes kind 2 is elevated, the mix has the extra good thing about the impact of acarbose on the postprandial glucose response.”
Holmback and colleagues carried out a single-center, randomized, managed, parallel-group, research to match the consequences on urge for food and tolerability of orlistat (Xenical, Roche) vs. three doses of a modified-release fixed-dose formulation of orlistat plus acarbose.
For the 2-week research, researchers assigned 16 wholesome males (imply age, 40.5 years; imply BMI 34.5 kg/m2; imply waist circumference 119 cm) to obtain a day by day dose of 60 mg orlistat/20 mg acarbose, 17 males (43.four years, 34.1 kg/m2, 119 cm) to obtain 90 mg of orlistat/30 mg acarbose, 16 males (42.three years, 34.eight kg/m2, 121 cm) to obtain 120 mg of orlistat/40 mg of acarbose, and 17 males (45.5 years, 35.four kg/m2, 119 cm) to obtain standard orlistat.
A modified-release fixed-dose formulation of orlistat and acarbose is properly tolerated and could also be an efficient method for weight reduction.

Individuals took their remedy with meals: at breakfast and lunch offered throughout research visits on days 1 and 14 and with three meals at dwelling on different days and dinner at dwelling on research days as properly. Individuals reported gastrointestinal signs and subjective urge for food through questionnaires for three days earlier than the research started after which after meals all through the research. Researchers took blood samples at the start, center and finish of the two weeks and at a follow-up go to on day 21.
The mix drug teams reported fewer orlistat associated adversarial results, reminiscent of liquid and oily stools, together with some acarbose-related adversarial results, reminiscent of flatulence and gastric distension. Extra contributors within the 90/30 and 120/40 dosage teams reported decreased starvation compared with the orlistat-alone group.
On days 1 and 14, the best blood glucose concentrations have been considerably decrease for the teams receiving any of the orlistat-acarbose combos vs. standard orlistat (P .05). The mix teams vs. the orlistat-alone group additionally had considerably decrease imply blood glucose concentrations and decrease most insulin concentrations at day 1, however not day 14 (P .05). Imply insulin concentrations have been related throughout teams on each research days.
No variations in reported starvation, emotions of fullness or want to eat have been noticed between teams for the 14-day interval. Numbers of contributors reporting a prespecified lower from baseline in starvation after lunch and dinner have been considerably bigger for the mix teams vs. the orlistat-only group.
These findings present it’s attainable to mix orlistat and acarbose in a modified-release formulation with out growing GI unintended effects, with extra advantages of lowering starvation and decreasing post-meal glucose concentrations, in response to the researchers.
“The impact on starvation, along with the consequences on glucose and insulin ranges, point out that the particularly designed launch charges of orlistat and acarbose set off programs concerned in urge for food regulation,” the researchers wrote. “These preliminary outcomes have to be confirmed in a research of longer period in a extra numerous inhabitants the place weight reduction is the first consequence.” – by Erin T.
