Anagrelide Hydrochloride(BL4162A) is a drug used for the treatment of essential thrombocytosis.Target: PDEAnagrelide hydrochloride is an oral imidazoquinazoline agent that has been shown to reduce elevated platelet counts and the risk of thrombosis in patients with thrombocythaemia in various myeloproliferative disorders (MPD). It is currently approved by the FDA as oral treatment for essential thrombocythaemia (ET) and thrombocythaemia associated with polycythaemia vera (PV). Anagrelide is known to inhibit platelet cyclic adenosine monophosphate (cAMP) phosphodiesterase at concentrations that exceed those achieved at doses used to treat ET. Anagrelide is extensively metabolised in the liver and its metabolites are primarily excreted in the urine [1]. Anagrelide is an established platelet-reducing drug. Studies have also investigated the effects of anagrelide on platelets, indicating that platelet function is as important as platelet counts in ET [2].

Adapalene sodium salt(CD 271; Differin), a synthetic retinoid, is a Retinoic acid receptor agonist (RAR).Target: Retinoic acid receptor agonist (RAR)Adapalene sodium salt is a third-generation topical retinoid primarily used in the treatment of mild-moderate acne and is also used (off-label) to treat keratosis pilaris as well as other skin conditions. Adapalene sodium salt is possibly more effective than tretinoin 0.025% gel in the treatment of acne vulgaris [1].Thirty-six rats of either sex were divided into six groups (two control groups, and an etodolac, indomethacin, tretinoin and adapalene sodium salt group) of six animals each. Each group was given different drugs or chemicals. The inhibitory activities of the drugs were determined on carrageenan-induced rat-paw oedema. The inhibition rate (53.48%) in the tretinoin group was found to be higher than adapalene sodium salt and controls (P < 0.05). Adapalene sodium salt was found to have an inhibition rate of 10.28%, and when compared with the other groups, was found to have no statistically significant anti-inflammatory activity [2].Clinical indications: Acne; Purpura; SunburnFDA Approved Date: 1996Toxicity: Skin redness; dryness; itching; scaling; mild burning

Mirodenafil 2Hcl(SK3530 2Hcl) is a phosphodiesterase type 5 (PDE-5) inhibitor developed for the treatment of erectile dysfunction.Target: PDE5Mirodenafil is a newly developed oral phosphodiesterase type 5 inhibitor. Mirodenafil, in doses of 50 or 100 mg, significantly improved erectile function and were well tolerated in a representative population of Korean men with broad-spectrum ED of various etiologies and severities [1]. The concurrent administration of mirodenafil with alcohol was not associated with clinically significant hemodynamic changes in these healthy male volunteers in Korea. The pharmacoki-netics of mirodenafil were not significantly altered by this concurrent administration. Mirodenafil administered with alcohol had a tolerability profile comparable to that of mirodenafil alone [2]. In these healthy Korean male volunteers, the coadministration of ketoconazole and rifampicin resulted in significant changes in systemic exposure to mirodenafil [3].
