Piroxicam, a non steroidal anti inflammatory drugs (NSAID), is an oxicam derivative which can be used for treatment of various rheumatic diseases, such as rheumatoid arthritis and osteoarthritis. Piroxicam patch is an affective approach evading piroxicam’s side effect such as peptic ulcer and first pass metabolism. One of the patch components is polymer that the function is to control the speed of drug release from the patch. The aims of this study were to determine the optimum formula of a combination of polyvinylpyrolidone (PVP) and Carbopol to % moisture content (MC) and the flux release in solid dispersion piroxicam patch using Simplex Lattice Design. Piroxicam was prepared in the form of a solid dispersion in PEG 4000 to increase its solubility. The design formula of solid dispersion piroxicam patch made with the ratio PVP : Carbopol, that were 1 : 0; 0.5 : 0.5; 0 : 1. The optimum formula was chosen with the ratio PVP : Carbopol, 1: 0, which gave the best result of % MC and flux release. The result of % MC was 6.91% and the result of flux release was 35.543 µg/cm2.menit1/2.

Diltiazem HCl is a class of benzodiazepine calcium channel blockers used to treat angina pectoris, arrhythmias, and hypertension. Diltiazem HCl improves first-pass metabolism, a short half time of 3-5 hours, and bioavailability of diltiazem for oral administration of about 40%. Mucoadhesive buccal film diltiazem HCl releases the drug to the buccal mucosa, so the first pass metabolism can be avoided because of its absorption through the venous system that flows from the cheek. This study aimed to study HPMC polymers and polyvinyl pyrrolidone (PVP) polymers on swelling index, residence time, mucoadhesive strength of mucoadhesive buccal film diltiazem HCl, FTIR, and drug release. The prepared film was evaluated for swelling index, mucoadhesive strength, and mucoadhesive residence time. The optimal amount for HPMC was 35 mg, and PVP was 15 mg. The combination of polymers with this amount can produce a swelling index was 3,00, mucoadhesive strength was 41,87 gF, and mucoadhesive residence time was 330,66. FTIR test indicated that there was no interaction between active function clusters of Diltiazem HCl and other excipients. The release of the optimum formula in the 360th minute was about 97.847%, following in the zero-order release model and Higuchi.

Piroxicam solubility in water is very small this cause problem in the process of absorption so that it’s required an optimal formula to establish the physical properties of tablet quality for piroxicam tablets. The purpose of this research was creating formulas with the optimal combination of excipients lactose, Avicel pH 101, and piroxicam amprotab to obtain tablets with good physical properties and disolution. Seven piroxicam tablet formulas were made with a combination of lactose, avicel PH-101, and Amprotab on 2 batches. Method for making tablets piroxicam was established by direct compression. Tests included were the physical properties of piroxicam tablets tablets weight uniformity, uniformity of size, hardness, brittleness, disintegration test, as well as dissolution test, and content uniformity. Based on the simplex lattice design method, lactose is a dominant factor to improved the uniformity of tablet’s concentartions. Interaction of two components avicel PH-101 and amprotab is a dominant factor to reduced vulnerability. Interaction of three components lactose, avicel PH-101 and amprotab is a dominant factor to lowered the value coefisien variation of weight uniformity, increased hardness, decreased the disintegration, and improved dissolution of tablets. Selection of the optimum formula was determined by the method of simplex lattice design through diagrams superimposed contour plots and contour plots for obtaining the optimal proportions of each ingredient as follows: lactose (85,154–100%), avicel PH-101 (0–12,437%), and amprotab (0–5,425%).
