Pharmaceutical cocrystals of tadalafil with methylparaben, propylparaben and hydrocinnamic acid were investigated.
A team from the United States report their study on the hydrogen bonding motifs in tadalafil cocrystals with the aim to produce a drug with enhanced solubility for better oral drug absorption. Tadalafil, currently used for the treatment of erectile dysfunction, is being explored as a treatment for pulmonary arterial hypertension so would be more useful for this application if the time taken to reach its peak plasma concentration was shorter.
