Abstract: The present invention incorporates medicaments in the empty hard capsule shells (body and cap). The medicament is either physically/molecularly distributed and/or chemically bound to the polymer matrix of the capsule shell composition. Other medicaments in the form of drug-loaded matrices (powders, granules, beads, pellets, mini-tablets, and mini-capsules) can be filled in the drug-loaded empty, hard capsule shells. The same capsule dosage form contains medicaments in the core matrix and in the shell.

Abstract: Ferrous sulfate and ferrous ammonium sulfate are known to kill moss and liverwort. They impart acidity in the lawn. Moss grows better in an acidic pH. The current invention proposes a formulation of ferrous sulfate or ferrous ammonium sulfate and zero valent iron with lime. Lime neutralizes the acidity produced by the ferrous salt and keeps the pH of the soil at 7 to 7.5. The formulation produces an immediate effect to eradicate moss and also provides a sustained effect over a long period. Another embodiment contains an addition of antimicrobial agents such as benzalkonium chloride, dichlorophen, and didecyldimethyl ammonium chloride to the ferrous sulfate-lime formulation.
